Ok, since the release today of v1.1.2 of the IOS Pilot app, I spent a bit of time running the simulator and have learned some interesting things:
1. the app now remembers the values input for RTH altitude and MAX flight altitude and restores them to the settings fields correctly between sessions.
2. these values are input as meters regardless of how you have the imperial/metric setting
3. although this is in the manual, I believe there are several crashes being caused in the user community by misunderstanding the fact that IF THE QUAD SWITCHES TO RTH MODE IT WILL DO ONE OF TWO THINGS. IT WILL IMMEDIATELY DESCEND AND LAND WHERE IT IS OR IT WILL MOVE VERTICALLY TO THE RTH ALTITUDE, THEN TRANSLATE TO A POINT AT THE RTH ALTITUDE ABOVE THE SAVED HOME POINT AND THEN DESCEND AND LAND. The absolute factor that decides between these two scenarios is the horizontal distance between the saved home point and the point below (or above) the P3. This horizontal distance is 20 meters which is 65 feet and altitude doesn't matter. If the P3 is 64 feet away from the home point (regardless of altitude), and it enters RTH mode, IT WILL DESCEND AND LAND RIGHT WHERE IT IS. If it is 66 feet from the home point when it enters RTH mode it will go to the RTH altitude, move horizontally to the home point and then land.
One More Time: <65 feet RTH lands where it is, >65 feet it goes home. Know it. Learn it. Be it. |
