The aviation terms operators search before they enquire.

Part 141

Part 141 is the US structured flight-training framework under 14 CFR Part 141 that lets FAA-approved academies teach reduced-minimum syllabi with regular stage checks.

Part 61

Part 61 is the flexible US flight-training framework where student pilots train under an individual CFI, typically at a non-TCO school or through independent instructors.

Part 135

Part 135 is the US regulation covering commercial on-demand air taxi and commuter operations — the certificate basis for legal for-hire charter.

Part 107

Part 107 is the US FAA Small UAS Rule that governs commercial drone operations under 55 lb, including daylight, visual line of sight, and remote pilot certification.

BVLOS

BVLOS (Beyond Visual Line of Sight) is drone operation where the pilot cannot see the aircraft unaided — enabling long-distance inspection, pipeline monitoring, and utility survey under specific regulatory waivers.

ICAO

ICAO is the UN specialised agency that sets global civil aviation standards, including the four-letter airport codes (KLAX, YSSY, EGLL) used in flight plans and aviation search.

Jet-A

Jet-A is the primary turbine-aviation fuel used by jet and turboprop aircraft, specified under ASTM D1655. Jet-A1 is the ICAO variant with a lower freezing point used outside North America.

Discovery Flight

A discovery flight is a short introductory flight (usually 30–60 minutes) a flight school offers prospective students — the first revenue event and biggest-impact conversion point in the training funnel.
