Hi all - I was flying a large area mission today, the wind was maybe 15mph max and had a large effect on two things which new pilots need to be aware of.
Firstly I didn’t take the wind into account when planning the survey from the comfort of my home. What actually happened is that I set the first capture point as the furthest away from me so that the aircraft would work its way back to me. However the head wind meant that the aircraft had a low ground speed and lost more than 10% battery power just getting to the first waypoint. It meant I had to abandon the mission near to the end, swap batteries, then re-plan the (relatively small) area it had missed.
The DroneDeploy software must use an interval timer to determine the gap between pictures. In other words, all the front overlap that you set is all over the place when you’re flying in the real world with wind. It has the effect of taking less pictures per area when travelling with the wind, and taking almost double when heading into the wind. This effect is obviously because of the speed difference. This surprised me.
I’ve uploaded a screenshot of the actual number of photos the software took and it’s easy to see where it was heading into the wind (travelling east) or with the wind (travelling west).
