What is the elevation of the TDZE for RWY 4?

To determine the elevation of the Threshold Designation Zone Elevation (TDZE) for a runway, it's essential to reference the airport's published data, such as the airport layout plans or the approach charts for the specific runway. In this case, the correct answer states that the elevation of the TDZE for RWY 4 is 44 feet Mean Sea Level (MSL).

The TDZE is a critical piece of information for pilots since it represents the elevation at which the aircraft is expected to touch down on the runway during an approach. Knowing this elevation helps in assessing necessary altitude corrections and in managing the approach and landing phases appropriately.

In this scenario, 44 feet MSL is consistent with the recorded data for RWY 4. This measurement is precise and published, ensuring that pilots can accurately reference it for their approach calculations. Understanding the significance of the TDZE elevation and its role in approach planning reinforces the importance of accurate airport data and its applications in real-world flying scenarios.
