Mapping Missions (Add the 'return to home' time)

João Marques

HI everyone.

I'm a new elite user (for mapping purposes) and so far (+- 10 flights) everything works very smooth and perfect during the missions.

I have just i idea / request for planning the missions, why not add to the flight mission the RTH time?

We currently have the Approach + Mission time flight but never the time from the last mission point to 'HOME'. It would help alot planning missions and give a more realistic flight time from take off and landing.

 

Just my 2 cents.

 

Thanks and congrats on the app.

 

JM

    The system can't compute the RTH details at planning time because it doesn't know where the home point is or what the RTH altitude is set to (both of these come from the connected drone).

    Jim McAndrew ok sounds logical, but in the mapping tool (pc) if we could 'choose' the home point to take off why doesn't the app use that home point as a landing point and give us a estimate time for the return?
    Is it a software limitation?

    Just asking out of curiosity and just because if would help ALOT planning.

    Thank you.

     

    Best,

    One more question, if you dont mine.

    when planning why cant i 'choose' from which side i wanna start, rather then what the software choose (even if i rotate the direction i cant choose from where part i wanna start)?

    Example, i wanna start from the upper right (closer to home point), rather then upper left (further from home point) - and it would consume less battery:

    What is the reference PIN? The dark purple? If so, wont change where it starts.

    Even if we allowed that, the software still doesn't know what the RTH altitude will be. Much of the RTH time is spend ascending and descending, so without this information the estimate would be meaningless. Theoretically, if you added an RTH altitude command the system could make a best guess, but again, still not really sure what the value is in any of this. You can already set what you think the usable amount time your batteries have, and the preview will show you how many batteries it thinks the mission will take.

    João. Sorry, I thought you meant where you wanted the drone to start/ launch from. Try moving the destination pin. This is where the mission will start the mapping. Hope this helps. 

    If you haven’t already, I’d suggest taking a look at the Dronelink 101 tutorials.

    In regards to adding the return time. Even at 2,000 feet away it would only take an estimated 60 to 90 seconds depending on which drone and the altitude. Just take the speed at which your drone returns home and times by 1.46667, or round it out to 1.47. It will give you the feet per second then calculate from there. I understand your request but it’s not much time even at that far a distance. Just a fun fact for the day. Lol…

    Also of I’m not mistaken, you can adjust the map so the ending point is closer to home-point. It will change the estimated time to run it since it uses the time starting from Take-off to the end point. Just a thought.. Enjoy.

    Mike (Arizona Wyldwest) after the today browser app update its working flawless! Now i move the approach pin and it changes to where i want it to start.

    Regarding, once again, the RTH time estimate i really dont care about the time of landing (it could be anything, since the app - like Jim says - dont know the RTH altitude), but i though that would be nice to have the estimate time between the final 'point' and the RTH point, before landing.

    But like Mike (Arizona Wyldwest) says its just a little gimmick nothing more.

     

    Anyway thanks for the fast reply and even faster fix in the app.

     

    Best regards,

    JM

    I don’t understand  "what the rth altitude is set to".

    This is a parameter that we can set in the appropriate command component.

    if you added an RTH altitude command the system could make a best guess

    Right, this is what I meant by this statement. If a mission plan had this command added (at the very start) it could make a guess, but it doesn't work this way right now, and we are unlikely to implement this feature request because it has limited value...

    just a little gimmick
