What is the elevation of the TDZE for RWY 4?

The correct elevation of the Touchdown Zone Elevation (TDZE) for RWY 4 is 44 feet MSL (Mean Sea Level). The TDZE is crucial in understanding the point on the runway where an aircraft first makes contact with the ground during landing. This elevation is determined by surveying the runway area and is vital for pilots to know since it affects landing calculations, including approach and descent profiles.

Typically, the TDZE is published in the airport's approach plates and is derived from the level of the runway's surface. Knowing the TDZE helps pilots maintain proper altitude during the approach and ensures that they have adequate clearance from obstacles in the surrounding area. The 44 feet MSL measurement indicates the altitude above sea level at which the aircraft should ideally touch down, allowing for safe and effective landing operations.
