Power-Off Stall
A stall practiced with idle or reduced power to simulate the approach-to-landing configuration and teach recognition and recovery near the critical angle of attack. Student pilots commonly log power-off stalls with slow flight and pattern work as foundational private-pilot maneuvers.

- Power-On StallA stall practiced with takeoff or climb power to simulate departure and departure-turn scenarios. Power-on stalls appear in private and multi-engine maneuver training so pilots can recognize an excessive angle of attack with power applied and recover promptly.
- Precision ApproachAn instrument approach that provides both lateral and vertical electronic guidance to the runway, such as an ILS, GLS, or PAR. RNAV (GPS) LPV and LNAV/VNAV procedures also provide vertical guidance and are flown to a decision altitude, but the FAA classifies them as approaches with vertical guidance (APV) rather than precision approaches.
- Preflight ActionThe pilot-in-command duty under 14 CFR 91.103 to become familiar with all available information concerning a flight before departure. Required items include runway lengths, takeoff and landing distances, weather reports and forecasts, fuel requirements, alternatives if the flight cannot be completed, and known ATC delays; "all available information" includes NOTAMs.
- Preflight InspectionA thorough visual and physical inspection of the aircraft performed by the pilot before each flight. The preflight checks fuel quantity and quality, oil level, control surfaces, tires, lights, and overall aircraft condition using the manufacturer's checklist.
