Why do helicopters have a higher collision rate as compared to aircraft?
Helicopters have a higher collision rate as compared to aircraft for several reasons,
Helicopters have more intricate machinery than planes, which requires maintenance and examination. Helicopters have a main rotor, a tail rotor, a transmission, and an engine, all of which are essential for aviation and control. Any failure or damage to these components can cause a disastrous crash.
Helicopters fly at lower altitudes and speeds than aircraft, which exposes them to more obstacles, such as power lines/grids, buildings, trees, and birds. Helicopters also have less margin for error and recovery in case of an emergency, as they cannot glide or divert to a nearby airport like planes can.
Helicopters are harder to fly and control than aircraft, especially in hovering and low-speed situations. Helicopters require constant and precise input from the pilot to maintain stability and direction, as well as coordination of the cyclic, collective, pedals, and throttle.
Helicopters are also more susceptible to aerodynamic phenomena, such as vortex ring state, retreating blade stall, and ground resonance, which can cause loss of lift or control.
