Flight Schools Industry Terminology
AATD/BATD (Advanced/Basic Aviation Training Device)
FAA-approved ground-based simulators used for training and proficiency; AATDs offer more capability and usually more credit than BATDs. They reduce cost, mitigate weather cancellations, and allow scenario-based practice of abnormal/emergency procedures.
We’ll move your lesson into the AATD to keep you progressing despite the low ceiling; You can log up to X hours of instrument time in our BATD toward the rating per FAA approval; The school’s ATD LOA is posted at dispatch for your instructor’s reference.
ACS (Airman Certification Standards)
FAA standards specifying knowledge, risk management, and skill performance for each certificate/rating. They replaced the older PTS and drive how schools design curriculum, study guides, and checkride prep.
Our syllabus maps every lesson objective to the Private Pilot ACS; The DPE will evaluate risk management elements per the ACS; Update the stage check rubrics to the latest ACS change notice.
ADM (Aeronautical Decision Making)
A systematic approach to risk assessment and decision-making in flight, integrating human factors. Common tools include PAVE, 5P, and the DECIDE model; emphasized across all training stages.
We’ll debrief your ADM using the 5P model; Strong ADM led you to divert early instead of pressing into worsening weather; Integrate ADM scenarios into the night cross-country lesson.
ADS-B (Automatic Dependent Surveillance–Broadcast)
A satellite-based surveillance technology; ADS-B Out broadcasts aircraft position and is required in certain airspace, while ADS-B In provides traffic and weather (FIS-B) to cockpit displays/EFBs.
All our rental aircraft are ADS-B Out compliant for Class C airspace; Use ADS-B In to monitor traffic but keep your outside scan; Maintenance just updated the ADS-B performance report after the transponder swap.
AGL (Above Ground Level)
A vertical reference to the surface beneath the aircraft, used for pattern altitude, maneuver heights, obstacle clearance, and weather minima interpretations.
Fly the pattern at 1,000 feet AGL; Stay at least 1,500 AGL for stall training; The cloud base is 2,500 AGL—legal for VFR training today.
AFSP (TSA Alien Flight Student Program)
U.S. TSA vetting program requiring non-U.S. citizens to receive approval before starting certain flight training (e.g., initial, instrument, multi-engine). Involves identity verification, fingerprints, and school validation.
International students must get AFSP approval before starting instrument training; Schedule fingerprinting for the AFSP Category 3 request; We cannot begin your multi-engine course until the AFSP training request is approved.
Annual Inspection
A comprehensive inspection required every 12 calendar months for all U.S.-registered aircraft. Flight school fleets also often require 100-hour inspections when used for hire.
The 172 is down for its annual—reschedule your booking; Plan the annual in the slow season to reduce revenue impact; The annual uncovered an AD that we must comply with before return to service.
AOA (Angle of Attack)
The angle between the chord line and relative wind. Mastery of AoA concepts helps prevent stalls/spins and manage performance, especially during takeoff/landing and maneuvering.
Watch the AOA indicator in slow flight to manage margin above stall; AoA awareness is central to our LOC-I prevention module; Don’t chase airspeed—fly AoA in the short-field approach.
ASEL/AMEL (Airplane Single-/Multi-Engine Land)
Common category/class ratings for fixed-wing pilots. Flight schools structure programs and marketing around these ratings, aircraft types, and progression paths.
She completed her ASEL and is enrolling in AMEL next; Our AMEL course uses the Seminole for multi-engine training; Market the ASEL-to-AMEL bridge package for commercial students.
Break-even Analysis
A financial tool that determines how many billable hours or students are needed to cover fixed and variable costs, guiding pricing, fleet sizing, and staffing decisions.
At current fixed and variable costs, our break-even is 280 Hobbs hours per month; Raising wet rates by $10 drops our break-even by 25 hours; Adding an AATD lowers break-even by shifting training to lower-cost time.
CAC (Customer Acquisition Cost)
All-in cost to acquire a new student (ads, sales time, tours, discovery flights). Key metric for marketing efficiency and budgeting.
Our CAC from Google Ads is $620 per enrolled private pilot; Lower CAC by optimizing the discovery flight funnel; Compare CAC to LTV to ensure marketing ROI.
CFI/CFII/MEI
Instructor certificates: CFI (flight instructor), CFII (instrument instructor), MEI (multi-engine instructor). Determine what and whom an instructor may teach and endorse.
We’re hiring CFII/MEIs for the fall instrument and multi demand; Your next goal after CPL is the CFI so you can instruct; Assign a CFII for the IPC candidates next week.
Checkride (Practical Test)
FAA certification test administered by a DPE or FAA inspector. Evaluates knowledge, risk management, and skill to ACS standards for the target certificate/rating.
Your checkride has an oral and a flight portion with the DPE; Let’s do a mock oral to prep for the ACS tasks; We’ll submit your IACRA and schedule the checkride once stage checks are complete.
Complex Aircraft Endorsement
Instructor endorsement required to act as PIC of a complex airplane (retractable landing gear, flaps, and controllable-pitch propeller). Often integrated in commercial training.
You’ll need a complex endorsement before renting the Arrow; The CPL course includes complex systems and retractable-gear ops; Document the complex sign-off in the student’s logbook per 61.31(e).
CRM/SRM (Crew/Single-Pilot Resource Management)
Techniques for managing all available resources—humans, equipment, information—to enhance safety and efficiency. SRM adapts CRM to single-pilot operations, emphasizing task management and automation use.
Incorporate SRM callouts during busy pattern ops; Multi-crew CRM skills carry into advanced instruction and safety pilot work; Use TEM within SRM to identify and mitigate threats.
CTAF/UNICOM
CTAF is the frequency for self-announced traffic communications at non-towered fields; UNICOM is a ground station (often the FBO) that may provide advisories and services.
Make standard CTAF calls on 122.8 leaving the pattern; Ask UNICOM for fuel and parking on arrival; Practice non-towered ops phraseology before solo cross-country.
Density Altitude
Pressure altitude corrected for non-standard temperature. A key factor in performance planning, especially at hot/high airports, affecting climb, takeoff distance, and engine output.
Today’s high DA increases takeoff roll—use performance charts; Teach DA effects during summer operations; Delay departure until cooler temps to reduce DA risk.
Dispatch
The school’s operational function that schedules and releases aircraft, tracks status/squawks, verifies endorsements/authorizations, and controls keys/logs for each flight.
Check with dispatch to confirm the aircraft’s squawks are cleared; Improve dispatch reliability by tightening return-to-service communication; Dispatch will place the keys and maintenance log in your binder 30 minutes before the flight.
DPE (Designated Pilot Examiner)
An FAA-authorized examiner who conducts practical tests. Schools coordinate closely with DPEs for checkride availability, standards interpretation, and feedback.
Book a DPE four weeks out due to backlog; The DPE prefers the oral first thing in the morning; Provide the DPE’s required documents checklist to candidates.
Dry Rate vs Wet Rate
Aircraft rental pricing conventions: wet includes fuel/oil; dry excludes fuel (renter pays separately or is reimbursed). Impacts billing, margins, and perceived price.
Our 172s rent wet; The Arrow’s dry rate plus current fuel price equals about $220/hour; Be transparent about fuel reimbursement rules for dry rentals.
EASA Part-FCL
European pilot licensing regulations (Flight Crew Licensing) governing training, testing, and licensing in EASA states. Important for schools serving international students and conversions.
Our partner academy delivers an integrated ATPL under Part-FCL; Convert your FAA CPL to EASA via a bridging syllabus; Ensure instructors are familiar with FCL.210 for PPL requirements.
EBITDA
Earnings before interest, taxes, depreciation, and amortization; a common metric for evaluating operational profitability and valuing flight school businesses.
Compare EBITDA across locations to evaluate performance; Sim costs flow through OpEx and affect EBITDA; Improving fleet utilization should lift EBITDA margin.
EFB (Electronic Flight Bag)
Tablet or phone-based cockpit information system replacing paper charts and more. FAA allows EFB use with appropriate backup and procedures; widely integrated into training.
Use ForeFlight as your EFB for planning and ADS-B weather; Ensure your EFB battery backup meets our SOP; The school’s EFB checklist includes NOTAM and performance verification.
Endorsements (Logbook)
Instructor logbook entries required by regulation (Part 61) to authorize specific privileges like solo, cross-country, complex/high-performance, knowledge tests, and practical tests.
You need a 61.87 solo endorsement before first solo; Enter the 90-day solo endorsement renewal today; Provide the knowledge test endorsement with your AKTR before the checkride.
F-1/M-1 Visa & SEVIS/SEVP
U.S. nonimmigrant student visa categories: M-1 (vocational, common for flight training) and F-1 (academic). SEVP/SEVIS manage school certification and student status tracking.
We issue the Form I-20 for M-1 students; Keep SEVIS records current when students change programs; Clarify that full-time enrollment is required for M-1 status.
FAR/AIM
The Federal Aviation Regulations and the Aeronautical Information Manual. Core reference for legal requirements and operating guidance in U.S. flight training.
Bring a current FAR/AIM to ground lessons; The answer is in 61.129 for CPL aeronautical experience; Use the AIM for phraseology and recommended procedures.
FBO (Fixed Base Operator)
Airport-based service provider offering fuel, parking, maintenance, and amenities. Flight schools often rely on or operate as FBOs for line services and facilities.
Coordinate with the FBO for fuel and tie-down; The FBO charges a ramp fee waived with fuel purchase; Our school subleases office space from the FBO.
FITS/Scenario-Based Training
FAA/industry approach emphasizing real-world scenarios, risk management, and decision-making over rote maneuver drills. Often integrated with simulators and ACS-aligned tasks.
Today’s lesson uses a FITS scenario with evolving weather; Grade risk management and SRM in each scenario; Scenario-based training better prepares students for real-world flying.
Flight Review (BFR)
A recurrent requirement under 61.56 every 24 calendar months, typically at least 1 hour ground and 1 hour flight, unless satisfied by certain recent checkrides or FAA WINGS credits.
Our BFR package includes 1 hour ground and 1.5 hours flight; Completing an additional rating resets your BFR clock; Tailor the BFR to the pilot’s typical missions.
FTD/FFS (Flight Training Device/Full Flight Simulator)
FAA-qualified simulation devices under Part 60. FTDs provide procedural training with varying fidelity; FFSs provide full-motion, high-fidelity training and testing.
The Level 5 FTD can credit instrument time in our syllabus; Airlines use Level D FFS for type ratings; Book the FTD for abnormal procedures we can’t safely do in the aircraft.
Glass Cockpit
Aircraft with electronic flight displays (PFD/MFD) and integrated avionics. Requires specific training on automation, failure modes, and information management.
Our G1000 glass fleet qualifies as TAA for commercial training; Include automation management in glass transition training; Compare PFD trend vectors to maintain stabilized approaches.
GNSS/RNAV (GPS)
Area navigation using satellite positioning (GPS). Enables RNAV approaches, en route navigation, and advanced minima (e.g., LPV with WAAS) integral to modern IFR training.
We’ll fly an RNAV (GPS) LPV approach using WAAS; Use RAIM prediction when planning legacy GPS ops; Teach CDI sensitivity changes on RNAV approaches.
High-Performance Endorsement
Required instructor endorsement to act as PIC of an airplane with more than 200 horsepower. Often combined with complex or TAA training in advanced courses.
Get your high-performance sign-off to rent the 182; Include engine management techniques in the endorsement flight; Log the endorsement under 61.31(f) in the student’s logbook.
Hobbs Time vs Tach Time
Two ways to measure aircraft usage. Hobbs is an electrically driven hour meter (often tied to oil pressure or master), while tach is engine RPM-based. Impacts billing and maintenance schedules.
We bill rentals by Hobbs but schedule maintenance by tach; Expect tach time to run slower in cruise; Clarify Hobbs vs tach to avoid billing disputes.
Hundred-hour Inspection
Inspection required every 100 hours of time in service when an aircraft is used to carry persons for hire or provide flight instruction for hire. Similar scope to an annual but at shorter intervals.
The 100-hour is due in 6 tach hours—plan a ferry to maintenance; Remember the 10-hour overage counts toward the next 100-hour; 141 operations must still comply with 100-hour when for hire.
IACRA
Integrated Airman Certification and Rating Application, the FAA’s web portal for pilot certificates and ratings. Handles applications, endorsements, and temporary certificates.
Start your 8710 in IACRA before the stage check; The CFI will approve your IACRA application after verifying your documents; The DPE pulls your IACRA file on test day.
IFR/VFR
The two primary flight rules sets: Visual Flight Rules and Instrument Flight Rules. Training progresses from VFR basics to IFR procedures, weather, and instrument approaches.
We’ll stay VFR for the first leg and pick up IFR for the return; Teach VFR cloud clearance rules early; File IFR to practice the RNAV arrivals.
IMSAFE/PAVE/5P
Common personal and operational risk assessment mnemonics: IMSAFE (personal fitness), PAVE (Pilot, Aircraft, enVironment, External pressures), and 5P (Plan, Plane, Pilot, Passengers, Programming).
Complete an IMSAFE check before the night lesson; Use PAVE to brief risks on this mountain flight; Reassess the 5Ps at top of descent as the weather changes.
IPC (Instrument Proficiency Check)
A check with a CFII to restore instrument currency after it lapses beyond the 6-month grace period. Covers specified tasks per the ACS/Instrument ACS guidance.
Book an IPC after your instrument currency lapsed; Use the FTD for holds and unusual attitudes in the IPC; The CFII will endorse your logbook upon successful IPC completion.
Knowledge Test (AKT)
FAA multiple-choice knowledge exam required before certain practical tests. Results are documented on an Airman Knowledge Test Report and have a limited validity period.
Your PPL knowledge test score is valid for 24 calendar months; We require three practice exams above 80% before endorsing the AKT; Bring your AKTR to the checkride.
LAHSO (Land and Hold Short Operations)
ATC procedure where an aircraft is cleared to land and hold short of an intersecting runway/taxiway. Pilots may decline; training covers performance, briefing, and compliance.
We’ll brief LAHSO and practice the decision to accept or decline; Decline LAHSO if you’re not comfortable or performance is tight; Review the hold-short points on today’s airport diagram.
LOC-I (Loss of Control Inflight)
A major accident category involving unintended departure from controlled flight. Training focuses on stall/spin awareness, energy management, and upset recovery techniques.
Our upset recovery module is designed to mitigate LOC-I risk; Emphasize AoA awareness to prevent LOC-I on base-to-final; Analyze the NASA data on LOC-I accidents in training.
MEL (Minimum Equipment List)
An FAA-approved list permitting operation with specified inoperative equipment under defined conditions. Many training aircraft operate without an MEL, using 91.213(d) and the Kinds of Operations Equipment List.
Without an MEL, use 91.213(d) and the KOEL to determine dispatch legality; Larger trainers may operate under an MEL approved by the FSDO; Teach MEL deferral procedures in commercial ops classes.
METAR/TAF
Routine and forecast aviation weather reports. Core to preflight planning and in-flight decision-making taught from the first lessons onward.
Decode the METAR to assess ceiling for solo; Compare TAF trends to choose a go/no-go time; Use EFB visualization to see METAR gaps along the route.
NOTAM
Notices to Air Missions conveying time-critical aeronautical information like runway closures, navaid outages, and TFRs. Essential preflight review item.
A runway closure NOTAM affects today’s pattern work; Check GPS NOTAMs for RAIM outages; Teach students to verify NOTAMs via EFB and FAA sources.
Part 61 vs Part 141
Two FAA training frameworks. Part 61 is flexible and instructor-driven; Part 141 uses an FAA-approved syllabus with stage checks and may allow lower minimum hours for certain certificates/ratings.
Our Part 141 syllabus can reduce minimum hours for some ratings; Part 61 offers more scheduling flexibility for working students; International students often enroll in structured 141 programs.
SMS (Safety Management System)
A formal, data-driven approach to managing safety risk, including policy, risk management, assurance, and promotion. Increasingly adopted by flight schools to improve safety culture.
File a safety report in the SMS after that bird strike; Our SMS identifies runway incursion hotspots at the home field; Use data from the SMS to update SOPs and training mitigations.
Stage Check
An evaluation milestone in structured syllabi (especially Part 141) conducted by someone other than the primary instructor, ensuring standardization and readiness to advance.
Schedule a stage check with an independent CFI; You must pass Stage 2 before first solo cross-country; Stage check feedback loops into the student’s remediation plan.
TCO (Training Course Outline)
A detailed syllabus used in Part 141 programs that defines lesson sequence, content, and evaluation standards. It underpins standardization and regulatory approval.
The TCO lists lesson objectives, hours, and stage checks; Submit the revised TCO for FAA approval; Map each lesson in the TCO to ACS tasks.
Utilization Rate
A measure of how effectively aircraft and instructors are used, often tracked as billable hours per aircraft per day or scheduled hours vs available hours. Key driver of revenue and profitability.
Our fleet utilization target is 3.5 Hobbs hours per tail per day; Weather cut utilization to 55% last month; Boost utilization with earlier first-lesson slots and an AATD fallback.
