Mount Etna is one of the world’s most active volcanoes and is in an almost constant state of activity. It lies above the convergent plate margin between the African Plate and the Eurasian Plate. It is the highest active volcano in Europe outside the Caucasus.[3] It is currently 3,326 m (10,912 ft) high, though this varies with summit eruptions.
Flying at such altitude is tricky because helicopters and multirotors don’t operate as safely as fixed-wing airplanes in the lower-density air found higher up in the atmosphere. Pilots who fly rotor aircrafts at mountain elevations have to learn to constantly calculate the difference between how much power they need for maneuvers such as taking off, hovering, and landing, and how much power they actually have, with air pressure and temperature critical factors.
Already at take off the drone was rising very slowly and not showing much interest in the project. But slowly we reached the planned altitude. Performing the flyover of the Central Crater it suddenly started descening like being sucked into the crater. Luckilly I found a small ascending current to bring me back up and could safely land. Mission Success and thank you Inspire!
