Formation Flight
Time-on-target timing aid
Free
Formation Flight is a timing aid for pilots flying time-on-target (TOT) and hack-time missions. Set a target and a TOT, or start a hack, and the app uses your device's GPS to show the numbers you need to arrive on time:
• Time, ETE, ETA, and your early/late Δ against the TOT, colour-coded against tolerances you choose • Current groundspeed and the groundspeed required to make the TOT • Distance and bearing to the target, plus your current track • Large, high-contrast readouts designed to be read at a glance in the cockpit • Screen stays awake while a flight is active
Plan flights ahead of time, pick targets on a map or by coordinates, and adjust the TOT or hack time in flight.
Formation Flight is a supplemental situational-awareness tool. It is not a certified navigation system and must not be used as a primary means of navigation, terrain avoidance, or traffic separation. Always fly the aircraft first and cross-check against primary instruments.
