Subsonic means any speed below the speed of sound. (Mach 1). So subsonic aircraft range from 0 - 661 knots at sea level. (Mach 1 is 661 knots at sea level.)
The correct term for this is subsonic, not infrasonic. And yeah, I wouldn't want to go above the speed of sound in a hang glider! So, yes, they fly subsonic.
Yes, an airplane travels faster than a bullet. The average speed of a commercial airplane is around 550-600 mph, while the speed of a bullet can range from 1,700 mph to over 3,000 mph depending on the type and caliber.
Small planes fly at 100 to 200 mph. Airliners fly around 350 to 500 mph. Jet fighters fly faster.
Yes, it is the transition from subsonic to supersonic and then back that causes the sound.
High-speed fighter planes have aerofoil-shaped wings.
Yes many jets can travel at this speed as can props
Bullets flies at the top speed of Mach 3 but almost Mach 4. There are some planes that can fly much faster than bullets but bullets used to fly faster than most planes(aircraft). Hypersonic aircraft can fly up to Mach 9. So yes, hypersonic aircraft can fly much faster than bullets. If these hypersonic planes can fly faster than bullets, they can fly alot faster than missiles. Missiles also flies around Mach 3 but hypersonic planes don't fly at that kind of speed. The top speed that hypersonic planes is nearly Mach 10(almost 10 times faster than the speed of sound).
air, speed, wings, a pilot (unless if your a UAV), balance, and a way of maintaining speed
Of course, planes can fly.
If they are in the air so the answer is no, because if planes fly at high altitude and at high speed. It makes it alot difficult to get planes shot down.
Every airplane has its own speed limits. Most small and commercial planes fly below Mach (the speed of sound). Military fighters and some other planes, like Concorde, fly above Mach, or supersonically.
it can fly
