Formation Lights locations are:

• A. On the wings only
• B. Two on each wing tip, one outside each vertical stab, one on each side of the forward fuselage just forward of the LEX
• C. On the tail
• D. On the landing gear doors

Answer: (B)

Formation lights are placed to give other pilots a reliable visual cue to maintain formation, especially in night or limited-visibility flight. The layout with two lights on each wing tip provides clear cues from the sides and at distance, while a light outside each vertical stabilizer adds visibility from rear-quarter angles, which are common when aircraft are offset in formation. Placing a light on each side of the forward fuselage just forward of the Leading Edge Extensions ensures there’s a bright cue visible from the front as well, helping lead or wingmen track position even if other lights are obscured by the aircraft’s own structure. This combination creates symmetric, multi-angle visibility, increasing safety and coordination in close formation. Lights mounted only on the wings would leave gaps in visibility, the tail-only option wouldn’t help with forward or side angles, and placing lights on landing gear doors would be impractical and unreliable during flight.
