How far away are flanker lights from the PI?

Flanker lights are positioned at a specific distance from the point of impact (PI) to provide visual references for jumpers during a parachute landing. The standard distance for flanker lights is 250 meters to the left and right of the PI. This placement ensures that jumpers can easily discern their landing zone and adjust their trajectory accordingly, particularly in conditions where visibility might be compromised.

Additionally, having the flanker lights at this distance allows for a sufficient buffer to ensure that jumpers can safely maneuver toward the landing area without jeopardizing their position. The 250-meter standard is widely recognized in jump operations and is crucial for maintaining the safety and effectiveness of the drop zone. This positioning aligns with established military and aviation practices, ensuring consistency across various parachuting missions.
