Step 5

This section teaches the concepts behind the aviation, regulation and safety assessments. The goal is candidate-level understanding: enough to recognize terminology, reason through workplace scenarios, and understand the environment in which FAA employees operate.

5.1 Aviation Fundamentals and the NAS

Aircraft operate through a structured system of airspace, airports, routes, procedures, navigation, surveillance and communications. Air traffic services coordinate aircraft movement, while pilots remain responsible for operating their aircraft in accordance with applicable rules and clearances.

5.1.1 Airport Areas

1. Runway: prepared surface used primarily for aircraft takeoff and landing.
2. Taxiway: route used by aircraft to move between runways and other airport areas.
3. Apron/ramp: area used for parking, loading, servicing and related ground operations.
4. Terminal: passenger/cargo processing building or complex; not a runway or hangar.
5. Hangar: building used for aircraft storage, maintenance or related work.
6. Control tower: facility from which controllers manage traffic on and near an airport where tower services are provided.

5.1.2 Aircraft and Flight Phases

Aircraft categories and types differ in performance and operating requirements. A basic flight sequence can include preflight, taxi, takeoff, climb, cruise, descent, approach, landing and taxi-in. Safety decisions can arise at every phase; a warning discovered before takeoff should be evaluated before continuing rather than ignored for schedule convenience.
