What is the actual height before landing and before take off?

The actual height before landing and before takeoff can vary depending on the specific aircraft and airport. However, in general, commercial aircraft typically fly at cruising altitudes of around 30,000 to 40,000 feet before landing and takeoff. During the approach and descent for landing, the aircraft gradually descends to lower altitudes, typically around 10,000 to 5,000 feet before touching down on the runway. Before takeoff, the aircraft taxis to the runway at ground level before ascending to its cruising altitude.

Before Landing:

- Height Above Touchdown Point (HATDP): This is the aircraft's height above the threshold of the runway when it reaches a specific point, typically 50 feet.

Before Takeoff:

- Height Above Ground Level (AGL): This is the aircraft's height above the ground when it reaches a certain point during the takeoff roll, typically 35 feet.
