Lift(carrying capacity), fuel economy, stresses on the air frame, temperature the air frame is exposed to.
Yes, jets are airplanes but they are called supersonic airplanes.
Airplanes had expedited traveling and could travel over any terrain. Land, Sea, Mountain,etc...
Now we have airplanes and cars now
Averages 370 knots
They eat cham chowder. Why?
Airplanes need a lot of speed to take off because they are not designed for vertical takeoff and are to heavy to do so.
Most of the planes can fly during windy times. But their speed decreases. Only small aircrafts like Cessna are affected by these wings. So they cannot fly.
Airplanes all have different speeds.
Airflow ans lift over the airframe is affected by the airplane's speed.
Speed, altitude, and cost.
The speed, and therefore also the wavelength (for sound of a given frequency), are affected by temperature.
how does is wind speed affected by altitude
