The higher that an airplane flies, the smaller the speed of sound.
The average speed of sound at sea level is about 343 meters per second or 768 mph, but The sound waves move slower the higher up in altitude you go. The speed of sound is nearly independent of pressure or density but does change with temperature, so the fact that the temperature generally decreases as altitude increases is the main cause for the lower speed of sound at the altitude of an airplane. Typically, for a plane at an altitude of 5 miles (8 kilometers, 26,000 feet) the speed of will have decreased about 10%.
At higher altitudes, the air begins to warm again, so above 10 kilometers, the speed of sound again rises.

What causes an airplane to change their velocity and direction?
Forces, these forces can be created by the environment or the airplane.
Why knowing the velocity of an airplane is more important to a traveller than knowing its speeda?
velocity is speed and direction. It would not be good to be traveling at a speed of 500 mph in the wrong direction!
What two factors determine the amount of lift achieved by an airplane?
velocity and the difference in pressure above and below the wings
Why use velocity?
If you have to fly an airplane in air with wind, or a boat in water with current, and meet a schedule, then you'll be using velocity almost before you know it, even if you don't know what to call it. And vectors too.
What is the definition of vertical velocity?
Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity.
What does it mean if an airplane has constant velocity?
it means that the airplane is staying in motion but will soon crash;)
What causes an airplane to change their velocity and direction?
Forces, these forces can be created by the environment or the airplane.
An airplane flying from New York to Los Angeles is traveling at a velocity of 1400 kph west There is a head wind with a velocity of 20 kph east What is the resultant velocity of the airplane in kph?
1380 kph west
How do you calculate tak-off velocity of airplane?
peak height = (take off velocity^2)/(2*gravity)
What is the velocity of an airplane that travels 500 km in 2 hours and 17 minutes?
The velocity of an airplane that travels 500 km in 2 hours and 17 minutes is 218.97 km per hr.
What is the terminal velocity of an airplane?
That is it's maximum speed. Different for every aircraft.
How far can an airplane travel in 5 hours if it is traveling at a constant velocity of?
It will fly exactly .
What is the velocity of an airplane that experiences a displacement of 580 m in the north direction in 2.5 s?
The craft's velocity is 232 meters per second north.
What is an airplane's velocity if it travels at 260 miles an hour heading northeast?
260 miles an hour
Why is it important for airplane pilots to know wind velocity and not just wind speed during a flight?
Wind velocity is vector quantity. direction is also important.
How do you find velocity of a paper airplane?
Paper airplane's velocity can be measured as any other object can be determined by measuring its displacement over time. In other words, time the glide and measure the distance. Then divide the distance by the elapsed time to get the average velocity of the flight.
What could describe an airplane's velocity?
The main two useful velocity measurements are... 1. KTAS- Knots (True Airspeed) 2. KIAS- Knots (Indicated Airspeed)
