Concerning the airfield in fig 37, what is true about REIL for RWY 22?

The correct response indicates that the REIL (Runway End Identifier Lights) for RWY 22 are positioned 213 feet from the threshold. This is relevant because it clarifies the operational design of the lights, which serve as a visual aid to pilots, particularly during takeoff and landing. The positioning of the REIL is crucial for safety, helping pilots visually confirm the runway's end and ensuring proper alignment during approaches.

Understanding the significance of REIL helps pilots assess their situational awareness during approach and landing, especially in low-visibility conditions. Therefore, knowing the exact distance that these lights are placed from the threshold is essential for planning and executing a safe landing.

To fully grasp why the other possibilities do not apply, it's important to understand a few key concepts:

• REILs are typically located at the runway threshold to assist in identifying the runway from a distance, making the first choice incorrect.

• Additionally, REILs are designed to be used for both visual and instrument approaches, so the claim that they cannot be utilized for instrument approaches does not hold true.

• REILs generally operate continuously, regardless of daylight, unless specified otherwise, which makes the assertion that they only function during daylight hours inaccurate.

Therefore, recognizing that RE
