Use the glossary to clarify the actual document and responsible reviewer. Loan proceeds, aircraft value, equity, insurance protection and legal qualification are separate concepts; no short definition establishes individual approval or coverage.
How to use this aircraft financing glossary
Use these terms to identify questions in a proposal, purchase agreement, insurance policy or loan document. A short definition helps you read those documents; it cannot supply the actual legal terms, determine coverage or establish qualification. When a term changes the transaction's economics, ask for its definition in the relevant document and a worked example using your proposed figures.
The glossary covers financing, ownership, insurance and operating arrangements because these subjects meet at closing. Keep the responsible reviewer clear. The lender confirms its financing conditions, qualified insurance advisers explain policy provisions, and aviation counsel addresses legal rights and structure. Technical condition still needs its own qualified review. Browse the buying and ownership library for longer explanations of individual subjects.
A: agreements, aircraft and amortization
Agreed Value
An aircraft value accepted for a stated insurance purpose under a particular policy. Read the settlement provisions, deductibles, exclusions and relevant endorsements. The stated value does not by itself promise a payment for every loss or establish the lender's accepted collateral value.
Aircraft Management Agreement
A contract defining services, authority and compensation for an aircraft manager. Identify which administrative, operational or maintenance-coordination tasks are included and who retains decisions. The agreement's title does not determine operational control, loan eligibility or the scope of insurance protection.
Aircraft Purchase Agreement
The sale contract stating the aircraft, parties, price and conditions of the proposed transaction. Financing, inspection, deposit and title provisions need to work together. AOPA discusses tailoring contingencies and deadlines to the purchase rather than assuming every deposit is automatically refundable. AOPA Finance: purchase agreements, deposits and contingencies
Airworthiness Certificate
An FAA document concerning authorization to operate the aircraft within its certificate category. A standard certificate's continuing validity depends on the conditions FAA describes, including conformity and safe condition. Possession of the certificate alone is not a current inspection or loan approval. FAA: standard airworthiness certificate scope and validity
Amortization
The pattern by which loan principal is repaid through scheduled payments. The amortization period used to calculate payments can exceed the contractual maturity, leaving a balloon balance. Ask for both the payment schedule and the balance due at maturity. AOPA Finance: understanding loan terms
Annual Percentage Rate (APR)
A measure that incorporates interest and applicable financing charges under the relevant calculation. CFPB distinguishes APR from the interest rate in its consumer auto-loan explanation. Aircraft disclosure requirements require separate applicability review; do not compare a nominal rate with an APR as equivalent numbers. CFPB: interest rate and APR are different measures
Asset-Based Lending
Financing in which identified collateral has a central role in the proposed credit structure. The description does not establish that repayment capacity, guarantees or other underwriting are ignored. Ask what value is accepted, how proceeds are calculated and what covenants apply.
B: balances and borrowers
Balloon Payment
A substantial remaining amount due at a specified point, often maturity, after the preceding payment schedule has not fully repaid principal. Refinancing or selling later is a plan subject to future conditions, not a guaranteed source for satisfying the balloon.
Borrower
The person or entity obligated under the loan documents. Identify every borrower and distinguish that role from an owner, pilot or guarantor. An aircraft's registered owner and the people supporting repayment may have different roles that require coordinated documentation.
C: cash, collateral and contract conditions
Cash Flow
Money received and paid during a defined period. Specify whether the discussion concerns business operations, household resources or the aircraft budget. A reserve transfer, loan principal payment and accounting expense have different meanings; make the scope clear before comparing figures.
Collateral
Property supporting a secured obligation. The security documents identify what is covered and the rights involved. Do not assume that an aircraft's advertised price, equipment invoice or insured value automatically establishes the collateral value accepted for financing.
Commercial Use
A description requiring clarification of the actual activity. Business travel, leasing, instruction and transportation for compensation can raise different legal, financing and insurance questions. Describe who operates and pays, the purpose and the passengers; a broad label alone does not resolve those questions.
Conditional Sales Agreement
A sale arrangement in which specified rights or completion depend on stated conditions. Determine exactly when possession, title, risk and payment obligations change. The label alone cannot establish priority, repossession rights or the filings needed for a particular aircraft transaction.
Cross-Default Clause
A provision connecting a default under one obligation to consequences under another. Identify the affected obligations, triggering events, notice and cure terms. A separate loan or guarantee may therefore matter even when the proposed aircraft payment itself has been made.
D: debt, depreciation and dry leases
Debt Service Coverage Ratio (DSCR)
A defined measure of cash available for debt service divided by the debt service included in the calculation. Ask how both amounts are determined. Different definitions and periods can produce different ratios; a numerical example is not an industry-wide approval minimum.
Default
A failure to satisfy an obligation identified in the governing documents. It may involve payments or other covenants. Review the actual triggers, notice provisions and remedies instead of assuming that default means only a late monthly installment.
Depreciation
A term used for accounting or tax cost recovery, and sometimes informally for falling market value. Those measures are not interchangeable. IRS Publication 946 describes tax depreciation and recovery-period classifications; a tax deduction does not establish an aircraft's resale loss or usable life. IRS Publication 946: tax depreciation and recovery periods
Down Payment
The buyer's contribution toward the purchase price beyond financing proceeds. Closing expenses, initial work and retained reserves may require additional resources. Reconcile a credited deposit within the price contribution so the same money is not counted twice.
Dry Lease
A lease of the aircraft without crew. The FAA emphasizes examining actual operational control and the arrangement in practice. The term does not by itself assign every maintenance or insurance expense or make a bundled aircraft-and-crew arrangement lawful. FAA: dry leases and actual operational control
E: equity, escrow and early repayment
Early Payment Penalty
A charge or calculation that may apply when debt is repaid early under the contract. Read its timing, formula and exceptions. Do not assume all aircraft loans have a penalty, that all penalties expire on the same schedule or that a partial payment is treated like a full payoff.
Equity
An ownership value after subtracting the relevant debt from an identified asset value. State which value and debt date you use. Gross equity differs from net sale cash after payoff charges, transaction costs and other adjustments; it is not automatically available refinancing proceeds.
Escrow
An arrangement in which a third party holds funds or documents under agreed instructions. Identify release conditions, responsibilities and fees. Using escrow does not itself establish aircraft condition, complete title clearance or satisfaction of every financing contingency.
F: fixed rates and terminology checks
Fixed Interest Rate
A rate that remains unchanged for the period specified in the agreement. Confirm whether that period covers the whole loan or an initial portion. A fixed rate does not guarantee that insurance, storage, maintenance or every other ownership payment will remain unchanged.
Float Plan
Clarify this wording with the person using it. Identify any proposed itinerary or notification, its recipient and purpose. Do not assume it means an FAA flight plan, loan funding plan or insurance approval. Obtain the actual document or requirement before relying on the label.
G: guarantees and grace periods
Grace Period
A specified interval relevant to a particular payment or other obligation. Read what it changes: a late charge, contractual default or another consequence. A grace-period reference is not permission to ignore due dates or an assurance about credit reporting.
Guarantee
A promise supporting another party's obligation, with scope defined in its documents. A guarantor's exposure and release conditions need legal review. Supporting repayment does not automatically confer aircraft ownership; the FTC makes that distinction in its consumer cosigning guidance. FTC: cosigning obligations and ownership distinction
H: hull coverage
Hull Insurance
Aircraft physical-damage coverage under a policy's terms. Identify covered risks, valuation, deductibles, pilots, uses and exclusions. Hull coverage is distinct from liability coverage, and evidence requested by a lender should be coordinated with the actual policy rather than an informal coverage description. AOPA: named pilots and open-pilot policy provisions
I: interest, installments and registration
Installment Loan
A loan repaid through scheduled installments under agreed terms. Determine whether each payment includes principal and interest, whether payments can change and what remains at maturity. An installment structure can still include a final balloon or separately payable fees.
Interest Rate
The rate used to calculate interest under the loan's specified method. Ask about the calculation basis and whether the rate is fixed or variable. It does not, by itself, express all charges or the total cost over your intended ownership period.
International Registry
The Cape Town system for registering specified interests in qualifying aircraft objects. FAA explains the system's aircraft-object eligibility and related processes. It is not limited simply to aircraft making international trips, and it does not replace every applicable domestic title or filing inquiry. FAA: Cape Town Treaty and qualifying aircraft objects
L: liens, value ratios and policy interests
Lien
A claimed or established interest affecting property in connection with an obligation. The type, validity, priority and release process need transaction-specific review. A seller's statement that a loan is paid is different from obtaining the relevant documented release and addressing recording requirements.
Loan-to-Value Ratio (LTV)
The relevant loan amount divided by the specified aircraft value. Identify the accepted value source and whether the lender instead limits proceeds by another measure. A percentage based on purchase price may differ from one based on an appraisal; neither alone establishes approval.
Loss Payee
A party identified to receive payment in specified circumstances under an insurance policy or endorsement. Review the exact lender-interest wording and obligations. Being named as a loss payee is not the same role as every insured party or a blanket guarantee of claim payment.
M: maturity and monthly obligations
Maturity Date
The date the remaining contractual obligation becomes due. Compare it with the amortization schedule and intended ownership horizon. A manageable installment can coexist with a substantial maturity balance, requiring resources beyond the normal monthly payment.
Monthly Payment
The scheduled monthly amount for the specified obligation. Identify what it includes and excludes. A loan installment is only one aircraft cash requirement; maintenance, insurance, storage, training, applicable taxes and irregular expenses belong in a broader ownership plan.
N: net worth and notices
Net Worth
Assets less liabilities using stated values and dates. Identify ownership shares, valuation assumptions and contingent obligations when requested. Net worth differs from cash available for closing: an illiquid ownership interest may have value without supplying immediately usable funds.
Notice of Default
A communication concerning an alleged default under applicable documents and law. Review the alleged issue, delivery requirements, response deadline and possible remedies with counsel promptly. Receiving a notice does not establish that every dispute or legal consequence has already been decided.
O: leases and origination costs
Operating Lease
A lease description whose legal, accounting and tax implications depend on the arrangement and applicable framework. Clarify rights, payments, maintenance responsibilities and return conditions. Do not infer an automatic off-balance-sheet result, tax deduction or FAA operational classification from the name alone.
Origination Fee
A charge associated with arranging or making a loan under the stated agreement. Confirm recipient, amount, timing, refundability and whether it is paid separately or included in financing. Including a fee in principal changes proceeds or repayment and should appear in your comparison.
P: principal, prepayment and purchase review
Personal Guarantee
A guarantee given by an individual supporting a specified obligation. Review whether it is limited, continuing or subject to other conditions. An entity as borrower does not itself establish that individuals have no personal exposure when separate guarantees are signed.
Pre-Buy Inspection
A buyer-directed technical review with an agreed scope for the candidate aircraft. AOPA Finance recommends independent expertise appropriate to the aircraft. The inspection is distinct from appraisal, title review and an assurance that no future maintenance expense will occur. AOPA Aviation Finance: independent pre-purchase inspections
Prepayment
Repayment before the scheduled date, either partly or in full. Ask how funds will be applied, whether a charge applies and what happens to future installments. An estimated principal balance may differ from the actual dated payoff amount.
Principal
The loan amount outstanding apart from interest not incorporated into that balance. Distinguish original principal from current principal. Fees financed into the original balance can affect principal, so do not assume the principal always equals the amount delivered to the seller.
Q: qualification
Qualified Borrower
A borrower satisfying the particular financing source's requirements for a stated proposal. The phrase is not a single national aircraft-loan credential. Confirm whether qualification is preliminary or final and which aircraft, insurance, valuation or documentation conditions remain.
R: recourse, refinancing and residuals
Recourse Loan
A loan allowing specified recovery beyond the collateral under its documents and applicable law. Ask which parties and assets may be exposed and whether limits or exceptions apply. Selling or surrendering the aircraft does not necessarily satisfy the entire obligation.
Refinancing
Replacing or restructuring existing debt through a new financing arrangement. Compare proceeds, payoff, fees, maturity and total obligations over a consistent horizon. Future refinancing depends on conditions then available; a present balloon should not be treated as already solved by a future application.
Repossession
A creditor's recovery of collateral following circumstances that permit it under the governing documents and law. Notice, procedure, sale and remaining obligations require legal review. Aircraft location, possession and lien priority can raise separate questions that a glossary cannot decide.
Residual Value
An estimated or contractually specified value at a future point, depending on context. Distinguish a forecast from a guaranteed purchase obligation or lease provision. Actual condition, market demand and transaction costs can change eventual proceeds.
S: security documents and rights
Security Agreement
A document granting specified security rights in identified collateral. FAA describes requirements for recording qualifying aircraft security agreements. The agreement and recording process need appropriate review; recording alone should not be described as proof that every competing interest has been eliminated. FAA: recording an aircraft security agreement
Security Interest
A creditor's interest in collateral supporting an obligation. Creation, enforceability, perfection and priority are related but distinct questions. Ask counsel and the title professional which documents, searches and filings apply to the aircraft and any qualifying engines or other objects.
T: terms, title and disclosure law
Term
The period relevant to a specified agreement or provision. Clarify whether someone means loan maturity, amortization, a rate period or a lease duration. Matching labels without matching dates can hide a balloon or change in pricing.
Title Insurance
Coverage against specified title risks subject to a policy's conditions, exclusions and limits. Identify the insured parties and risks actually covered. It is distinct from physical-damage insurance and should not be assumed to insure every defect or replace the underlying title work.
Title Search
A review of specified records for ownership and recorded interests. Ask which records, jurisdictions and aircraft objects are included and how new filings and releases will be handled at closing. The scope matters; a search should not be described as a universal guarantee against all claims.
Truth in Lending Act (TILA)
A federal consumer-credit disclosure framework implemented in relevant part by Regulation Z. Applicability requires review: section 1026.3 includes business-purpose, organizational-credit and amount-based exemptions with qualifications. Do not assume every aircraft loan receives identical consumer disclosures or protections. Regulation Z 1026.3: exempt transactions
U: underwriting and useful life
Underwriting
The financing source's evaluation of a proposed borrower, collateral and transaction under its criteria. Distinguish an initial discussion, conditional decision and completed requirements. A document request or preliminary indication is not necessarily a binding commitment to fund.
Useful Life
An estimate of the period an asset can provide service in the relevant context. Economic service life, maintenance limits, market value and tax recovery periods are different concepts. IRS guidance uses specified classifications for tax recovery; do not substitute an assumed aircraft lifespan for that analysis.
V: variable rates
Variable Interest Rate
A rate that can change according to agreed provisions. Identify the index, margin, reset dates, floors, caps and payment effects if present. Use a sensitivity calculation based on the actual terms rather than assuming that today's installment continues through maturity.
W: wet leases and working capital
Wet Lease
Under the definition in 14 CFR 110.2, an arrangement providing the entire aircraft and at least one crewmember, excluding the stated codesharing arrangement. Actual operational authority and control still require review. It is not simply any lease that includes maintenance or insurance charges. 14 CFR 110.2: wet lease definition
Working Capital
Generally, current assets less current liabilities in the stated financial analysis. Identify which assets and obligations are included and their dates. Working capital differs from unrestricted cash immediately available for an aircraft deposit, down payment or ownership emergency.
Worked example: four numbers that are not interchangeable
Assume a fictional $200,000 purchase price, $180,000 accepted appraisal and $135,000 financing proceeds. The proceeds represent 75% of the assumed appraisal, but 67.5% of the purchase price. The buyer must supply $65,000 toward the price before separate transaction costs. Neither percentage establishes an actual lender policy or an available offer.
In a separate ownership snapshot, assume $190,000 market value and $140,000 current principal. Gross equity is $50,000 before sale costs, payoff adjustments and other obligations. That snapshot is not the same transaction or date as the purchase example and does not establish cash a refinancing source will advance.
For another simplified example, assume defined annual cash available for debt service of $18,000 and included annual debt service of $12,000. DSCR is 1.5. The result depends on those definitions and does not establish an approval threshold. Reconcile your own figures with the provider rather than substituting this illustration for underwriting.
Continue with loan terms and payment structures and title and lien protection questions. Use a consistent set of terms, dates and document references when comparing actual proposals.
