WebSpeed and range. Helicopters are slower and have a shorter range than airplanes. This is compensated by their maneuverability. Jet airplanes can cruise at high speeds, using much less fuel than helicopters, which makes them ideal for long flights. Some airplanes are capable of flying up to 18,000 km (9,700 nmi). WebThe reason why the wing stalls when it exceeds its critical angle of attack is that the airflow over the top of the wing separates. When the airplane exceeds its critical Mach number …
