Hi,
so just completed my first flights on the mavic air ... and it was fantastic fun, very stable, yet very nimble - going to be lots of fun.
a couple of questions came up whilst flying though, some of which related to where my home/flying site is.
Im at 1300m, and living on a kind of headland in southern spain in the mountains, on one side rises up a gentle slope, and on the others sides falls off quickly
a) Altitude and RTH etc
so I take off, and the Air records a RTH point - I assume this is consider level 0 ?
so when its says height on the screen, this is height above RTH point NOT height above the ground.
correct? so if Im going up a slope, and say need 10 meters clearance on trees - then I need to take care of the slope change.
Ive all sensors turned on, will at some point the Air notify me if its getting close to the ground?
I assume for RTH altitude I set it at slope + tree height for safety.
(though obstacle avoidance might stop it running into a tree/ground?!)
b) RTH oddity whilst landing
so on one occasion, I got it to RTH from a distance... with a altitude of 40m.
it flew back fine,
but then it seemed like it was having difficulties descending ... almost losing height then gaining it again. (it wasn't particulary windy)
I ended up pulling down the stick, and it came straight down - but I was a little confused why this was needed.
(as I said, first flights so, it may be it was just 'going thru the motions' that i was unaware of)
c) RTH accuracy
how accuately does it usually land on a RTH spot, it seemed to be within a few meters. (I had abotu 18 sats locked so seemed good reception)
is this correct?
d) can i reset a RTH point some how? will this reset the altitude lvl?
e) do birds strike drones ?
after abotu 30 mins, I had quite a number of swifts (or perhaps martins) appear , definitely the drone had 'interested' them, as they'd come from nowhere and went away when I landed it... they swooped around a bit, but didn't seem to want to attack it...
also we have eagles and vultures around, so wondering if I need to take care.
(Obviously not only do I not want the drone downed, but also I dont want to hurt any birds!)
f) wind / thermal effects?
this is kind of related to (b) , im wondering at 1300m in a warm climate, do I have to be particularly careful of any kind of thermal effects, or wind being higher relative to my ground point than (e.g.) if i was at sea level?
will the drone warn me if it detects high winds.
as a newbie, Im guess Im a bit concerned at what constitutes higher winds, even at 30-40 above my level where it is calm,
Im sure I will get used to this, but wondered if some might be able to advise me a bit on what to expect / be careful of !
as i said a thoroughly enjoyable first few flights, and looking forward to going out again tomorrow and gaining some more experience
