I've been invited to do a demo flying session with a sporting club which has a massive indoor arena. However the arena is within 1.5km to 2.0km of Tullamarine (Melbourne International) airport. I'm using the latest software on all apparatus (bird, controller, dji app); 1. If I take off from the furthest end from the airport and get to say 100ft in height if I fly closer to the airport will it force me lower? Obviously in the 1.5km range it will land if i've read the information correctly, but is it in any mode (GPS, ATTI, Manual)? 2. Will ATTI mode be sufficient indoors? 3. Given I haven't done much manual flying (Husban X4 maybe for 20 hours), how much harder is it flying compared to GPS or ATTI given it's indoors and there isn't (or at least I don't think there is) much of a breeze? 4. How do you get to manual when the bottom of the S1 switch is set to RTH? 5. If on the day say there is a thunderstorm outside, how would this affect the bird given it's inside? I believe the compass would be a concern? 6. Would you calibrate the compass inside the building or outside? With the above I'm not keen on downgrading for potentially one or two flights (as it's definitely going to be a one off) as i'd prefer to keep it as it is given my bird is flying quite nicely. Sorry for all the questions and look forward to the replies!
