Answer :

Final Answer:

A displaced threshold on an instrument runway is indicated by runway markings that consist of a white threshold bar followed by chevrons.

Explanation:

A displaced threshold is a portion of the runway where landing is not permitted, typically due to obstructions or other safety considerations. The runway markings for a displaced threshold include a white bar followed by a series of chevrons extending into the runway.

The white bar indicates the beginning of the displaced threshold, and the chevrons emphasize the portion of the runway where landing is not allowed. Pilots are advised to land beyond the displaced threshold markings. This configuration allows for safe takeoff and landing operations while considering any obstacles near the runway's approach.
