Anyone know how long a typical lets say news helicopter can last in the air given how much fuel it holds? I am not sure but I heard a news helicopter or a police helicopter probably wont last more than 3 hours in the air. Some military transport helicopters can only do about 2 and attack helicopters like the apache longbow attack helicopter probably wont last more than 30 minutes due to its weight from holding armaments. Some vertical takeoff aircrafts (harrier) probably can't last more than 2 minutes before using too much fuel to land safely. This is all what I have heard from other sources, I was wondering if anyone can shed some light on this subject.
