Density altitude, valley wind and terrain — flying where the aircraft has less to work with than the manual assumes.
Manufacturer performance figures are quoted at sea level in still air. Take the same aircraft to 3,000 metres and it has meaningfully less thrust available, a longer stopping distance, and a much smaller margin when the wind picks up.
This is our home ground. Mountain flying in Nepal is not an edge case we accommodate — it is the default condition, and it kills more drones here than any other single factor.
The course covers what altitude does to a rotor, how valley and slope winds behave through the day, how to plan a flight where the aircraft cannot simply climb out of trouble, and how to read terrain before you commit.
Tell us what you want to be able to do and we'll tell you which course gets you there — or that you don't need one.
