The Aviation Glossary

A

ATP (Airline Transport Pilot)

The highest FAA pilot certificate and the legal minimum for airline captains and, since 2013, airline first officers. Requires 1,500 hours, age 23, and the ATP Certification Training Program.

AME (Aviation Medical Examiner)

A physician designated by the FAA to issue medical certificates. Your first stop before serious training money gets spent.

ATC (Air Traffic Control)

The ground-based network that sequences and separates aircraft. Talking to ATC crisply is a learned skill and a hiring signal.

B

Bravo airspace

Class B, the controlled airspace wrapped around the busiest airports. Flying through it requires a clearance, and training in it builds radio confidence fast.

Block time

Time from the moment an aircraft first moves under its own power until it stops at shutdown. Airlines pay pilots by block hour.

C

CFI / CFII / MEI

Certificated flight instructor; the II adds instrument students, the MEI adds multi-engine students. The classic paid route from 300 hours to airline minimums.

Checkride

The practical exam ending every certificate: an oral examination plus a flight test with a designated pilot examiner.

Cross-country

Any flight with a landing beyond 50 nautical miles from departure. Specific cross-country totals gate the private, commercial, and ATP certificates.

Class 1 / 2 / 3 medical

The three FAA medical certificate levels: first class for airline captains, second for commercial privileges, third for private and student flying.

D

DPE (Designated Pilot Examiner)

An FAA-designated examiner authorized to conduct checkrides. Examiner availability is a real scheduling factor; good schools book them early.

Discovery flight

A paid introductory lesson where you handle the controls with an instructor. Loggable, inexpensive, and the correct first step.

F

FAA (Federal Aviation Administration)

The US regulator for civil aviation: certificates, medicals, airspace, and the rulebooks schools teach under.

FBO (Fixed-Base Operator)

The service business on an airport: fuel, parking, rentals, and often the flight school's front desk.

Flow agreement

A contractual pipeline moving pilots from a regional airline to its partner major without a separate application, like Envoy to American.

14 CFR Part 61 / Part 141

The two federal rulebooks for flight training. Part 61 flexes around your life; Part 141 runs an FAA-audited syllabus with lower minimums for some certificates.

G

Glass cockpit

Flight decks with digital displays like the Garmin G1000 replacing round-dial instruments. Standard equipment in modern trainers and every airliner.

Go-around

Rejecting a landing and climbing away to try again. A normal, trained maneuver, not an emergency, and examiners love a decisive one.

H

Hood

A view-limiting device worn in training to simulate instrument conditions while a safety pilot or instructor watches for traffic.

Hour building

The stretch between the commercial certificate and 1,500 hours, filled by instructing, towing, surveying, or flying freight feeders.

I

IFR / VFR

Instrument flight rules and visual flight rules, the two legal frameworks for operating. Airlines live in IFR; your instrument rating is the ticket in.

IOE (Initial Operating Experience)

Your first airline trips flown on real routes with a training captain after simulator school.

K

Knot

One nautical mile per hour, aviation's speed unit. A 120-knot trainer covers about 138 statute miles per hour.

L

Logbook

The legal record of every hour, endorsement, and checkride you accumulate. Digital or paper, it is your career's ledger; guard it accordingly.

Line flying

Regular scheduled flying at an airline, as opposed to training or reserve duty.

M

Multi-engine rating

The add-on rating for aircraft with more than one engine. Airlines expect it, and twins teach the asymmetric-thrust discipline jets demand.

Minimums

Both the FAA hour floors for each certificate and the lowest weather conditions an approach may legally be flown to. Context tells you which.

N

NOTAM

Notice to Air Missions: time-critical bulletins about runway closures, airspace changes, and hazards. Reading them is preflight hygiene.

P

PIC / SIC

Pilot in command and second in command. PIC time is the currency of a resume, and building it is the point of the CFI years.

Part 121 / Part 135

The operating rulebooks: 121 governs scheduled airlines, 135 covers charter and smaller cargo operators. Many careers pass through 135 on the way to 121.

PPL (Private Pilot License)

The first full certificate, formally the private pilot certificate. You fly friends and family; you just can't charge them.

R

R-ATP (Restricted ATP)

A reduced-minimum ATP for structured backgrounds: 750 hours military, 1,000 with an approved bachelor's degree, 1,250 with an associate's. Age 21 instead of 23.

Reserve

Airline duty where you're on call with a report window rather than holding a scheduled trip. Junior pilots start here.

S

Solo

Flight with you as the only occupant, first reached around your mid-teens hours in training. Nobody forgets theirs.

Seniority

The date-of-hire ranking that governs an airline pilot's schedule, aircraft, base, and upgrades. It is the reason start dates matter.

Sim (Full-flight simulator)

A motion simulator faithful enough that airline type ratings are earned entirely inside one before you touch the jet.

T

Type rating

The aircraft-specific certification for jets and large aircraft, like a 737 or E175 rating. Airlines pay for yours during new-hire training.

TAA (Technically Advanced Aircraft)

Aircraft with glass panels and autopilot meeting an FAA definition; commercial students can use TAA time in place of some complex-aircraft time.

V

V-speeds

The lettered reference speeds that structure every flight: VR for rotation, VX and VY for climbs, V1 as the takeoff decision speed at the airlines.

VOR

A ground-based radio navigation beacon, still taught, still tested, still working when the GPS constellation has a bad day.

W

Written (knowledge test)

The computer-based exam preceding each checkride, drawn from published question banks. Modern prep apps make a 90-plus score a study-discipline question.
