What color are the last 2,000 feet (or last half, whichever is less) of runway edge lights on a runway longer than 4,000 feet?
Answer: Yellow
Runway edge lights transition from white to yellow (amber) in the caution zone — the last 2,000 feet or last half of the runway, whichever is less.
A pilot using PAPI sees all four lights showing red. What does this indicate?
Answer: Well below glidepath
Four red PAPI lights indicate the aircraft is well below the glidepath and at risk — the common mnemonic is 'all red, you're dead.'
On a standard 2-bar VASI, which combination indicates the aircraft is on the correct glidepath?
Answer: Near bar white, far bar red
On a 2-bar VASI, a white near bar and red far bar means the aircraft is on the correct glidepath — 'white over red, you're ahead (on glide).'
Runway End Identifier Lights (REIL) consist of:
Answer: Two synchronized flashing lights flanking the runway threshold
REIL consists of two synchronized omnidirectional flashing white lights, one on each side of the runway threshold, to improve threshold identification.
Touchdown zone lights (TDZL) extend from the threshold for how far down the runway?
Answer: 3,000 feet
TDZL consist of two rows of transverse white light bars extending 3,000 feet from the runway threshold to aid pilots in identifying the touchdown zone during low-visibility approaches.
The Approach Lighting System with Sequenced Flashing Lights (ALSF-2) is primarily designed for:
Answer: Category II and III precision instrument approaches
ALSF-2 is a high-intensity approach lighting system with sequenced flashers designed for Category II and III ILS precision approaches in very low visibility conditions.
A displaced threshold is indicated by:
Answer: Red lights across the original threshold and white lights at the displaced threshold
Red threshold lights face outward (toward approaching aircraft) at the original threshold end, while green lights face inward at the displaced threshold, showing the area before it is unusable for landing.
