Samuel Tabor 75f772b269 AP_Soaring: Add SOAR_MAX_RADIUS parameter, that defines when a RTL will be used when exiting LOITER. 2020-04-08 09:11:54 +10:00
Samuel Tabor 298088268a Plane: Soaring, don't wait for heading if too low, and add timeout otherwise. 2020-04-08 09:11:54 +10:00
Samuel Tabor 684ee11fc3 AP_TECS: Add flags to indicate gliding flight, and use these with AP_Soaring. 2020-04-08 09:11:54 +10:00
