Shock horror - wazzing and zooming at high AUM and speed to show off to pax often leads to disaster!
As discussed on this forum before, the 350 has exactly the same problems with servo transparency/jackstall as the Gazelle so its not like it should have come as a surprise to Airbus/Eurocopter/Aerospatiale.
Every Brit Mil helicopter pilot trained on the Gazelle will have been shown the entry to and recovery from jackstall/servo transparency exactly because it is dangerous.
