I see a lot of RTH questions, and some misunderstanding of its function. Some only believe it's an emergency feature, which it can be, but there are three valuable RTH modes. The RTH function can be extremely useful and relieve a lot of stress returning your P3. It also has some useful alterations while flying back.
Failsafe RTH: When the RC & P3 lose signal for 3 seconds, a Failsafe RTH initiates and the P3 returns and lands at its takeoff point. It can be cancelled with a tap of the RTH button on the RC, or through the soft button on the app once signal is regained.
Smart RTH: When the P3 determines the amount of energy needed to return to its take off point has been reached due to distance from the Home Point, it initiates a Smart RTH. This can be disabled in the app, and will only activate once for each flight. If cancelled from the controller or app, it will not re-initiate because of battery levels.
RTH: User initiated return to the home point. Inside of 20 meters, a user initiated RTH will auto land at its location. Outside of 20 meters, the P3 will return to it's home point.
Return to home can be cancelled at any time by the operator, and also re-initiated as well manually from the RC or app. In all of the above, if one of the RTH modes kicks in and the P3 is below the Failsafe Return-to-Home-Altitude, the P3 will ascend and return. Above this limit, it will just RTH at its current altitude.
In all above modes, the operator can alter the P3 in various ways with the control sticks. As a picture is worth a thousand words, there's about 4000 below! Hope this helps anyone who may have RTH questions and/or fears. Feel free to ask any other questions you may have.
