Slip/Skid
Uncoordinated flight conditions. A slip occurs when the aircraft is banked too much for the rate of turn (ball deflected toward the turn). A skid occurs when there is too much rudder for the bank angle (ball deflected away from the turn). The inclinometer (ball) indicates coordination.

- Solo FlightA flight in which the student pilot is the sole occupant of the aircraft. Before the first solo, the student must receive endorsements from their flight instructor certifying competence in the specific aircraft type and at the specific airport.
- StallAn aerodynamic condition where the wing exceeds its critical angle of attack and can no longer produce sufficient lift to sustain flight. A stall can occur at any airspeed, in any attitude, and at any power setting — it is always caused by exceeding the critical angle of attack.
- TAF (Terminal Aerodrome Forecast)A weather forecast in coded format issued for airports, covering a 24 or 30 hour period. TAFs predict wind, visibility, cloud cover, and significant weather changes. Pilots use TAFs alongside METARs for flight planning decisions.
- TransponderAn electronic device in the aircraft that transmits a coded signal when interrogated by ground radar. Mode C transponders report altitude. Mode S transponders support ADS-B Out, which is required in most controlled airspace.
