How do pilots measure altitude and speed while flying?

Question

What are the method?
What are the equipments involve and how do the work?

Answer 1

Altitude is measured using an altimeter which works with barometric pressure.
Your height is calculated according to the pressure reading.
Your height above ground is different than pressure altitude.
You may go up or down in relation to the ground but your flight level will remain the same as you are flying the pressure reading.
Airspeed is read with the pitot tube/static port.
It reads the difference between the two and it shows your airspeed which is called indicated speed.
Your ground speed is different.
Your airspeed indicator can show 100mph while your ground speed or true speed can be 50mph.
Why is that? Well you can be flying with the wind or against it.
Hope I helped.

Answer 2

The altimeter measures air pressure. As the plane ascends and the air gets thinner, the atimeter reflects the change. The pitot tube measures the force of the incoming air or wind speed against the plane. This will give them their true airspeed or speed in relation to the still air. Pilots can calculate ground speed by using a GPS (which can also calculate altitude) or by using an estimate of the wind speed and direction against their true airspeed.

Answer 3

I'm no pilot but they probably use a pitot tube to indicate wind speed. That measures the difference in pressure of your outside air with respect to pressure build up as a result of wind speed. Knowing that pressure differential and the density of air you can calculate the wind speed. Just do a search on wikipedia.org for more info. There is more to it than just a reading a magical guage that just "knows" where you are and how fast you are going. And actually wind speed does not tell you flying speed. That only tells you how fast you are going with respect to the air. If your wind speed is 80mph, but the head wind is 15mph, your ground speed is only 65mph.

Answer 4

The standard flight instruments for aircraft use barometric pressure differential to indicate altitude (altimeter) and pitot/static air pressure differential to determine airspeed.

Altitude and groundspeed can also be measured with modern satellite based electronic devices such as GPS, and larger commercial aircraft frequently use RADAR altimeters for determining height above ground during landings and take-offs.

Answer 5

Ditto - Using an altimeter to determine altitude and air speed indicator to determine speed.

Answer 6

Using an altimeter to determine altitude and air speed indicator to determine speed.

Answer 7

one way is to look out the window!!! air pressure will determine altitude and wind speed will determine flying speed

Answer 8

They look at the altimeter and air speed indicators.
