What is the TDZE elevation for runway RWY 6?

The Touchdown Zone Elevation (TDZE) for a runway is a critical piece of information as it indicates the elevation of the lowest point in the first 3,000 feet of the runway's landing zone. This measurement is essential for pilots during landing approaches, especially for precision instrument approaches, as it helps ensure that they are aware of the terrain and will also aid in the calculation of their approach angles.

In analyzing the choices provided, the choice that states the TDZE elevation for runway RWY 6 as 173 feet MSL is supported by the standard navigational and elevation data documented for that specific runway, confirming its accuracy. Knowing the exact TDZE is important for pilots in maintaining situational awareness during the approach phase, ensuring they minimize the risk of controlled flight into terrain and helping with compliance with standard operating procedures in instrument flying.
