Final Approach
The last segment of an instrument or visual approach procedure in which the aircraft is aligned with the runway and descending for landing. During instrument approaches, the final approach begins at the final approach fix (FAF).

- FlapsHinged surfaces on the trailing edge of the wing that increase both lift and drag when extended. Flaps allow the aircraft to fly at slower speeds during approach and landing, and enable shorter takeoff rolls. Common types include plain, split, slotted, and Fowler flaps.
- FOI (Fundamentals of Instruction)The body of knowledge covering the learning process, teaching methods, assessment techniques, and human behavior that flight instructor candidates must master. The FOI written test is required for all initial CFI applicants.
- GPS (Global Positioning System)A satellite-based navigation system that provides precise position, altitude, and ground speed information to aircraft. GPS is the primary means of navigation for many IFR procedures including RNAV approaches.
- Ground EffectAn increase in aerodynamic efficiency that occurs when an aircraft flies very close to the ground (typically within one wingspan height). Ground effect reduces induced drag, which is why aircraft may float during landing if carrying excess speed.
