SAE ARP693E Landing and Taxiing Lights – Design Criteria for Installation

SCOPE

This document includes requirements of installations of adequate landing and taxing lighting systems in aircraft of the

following categories:

a. Single engine personal and/or liaison type

b. Light twin engine

c. Large multiengine propeller

d. Large multiengine turbojet/turbofan

e. Military high-performance fighter and attack

f. Helicopter

This document will cover general requirements and recommended practices for all types of landing and taxi lights. More specific recommendations for LED lights in particular can be found in ARP6402.

Purpose

The purpose of this document is to provide certain basic considerations and design criteria for installation of landing and taxing light systems for night operation. These recommendations can be used to provide criteria for adequate lighting for the FAA or other certifying authority.

Landing Lights

Landing lights are used primarily to provide ground reference information during final approach, touchdown,
ground roll, and takeoff, and to illuminate any major obstructions in the airplane’s approach glide path or on the runway at night.

Taxi Lights

Taxi lights are not required by the FAA. When present, they are used to provide illumination when the aircraft is maneuvered on the ground at night. They typically have a wide pattern to illuminate the full width of the runway.
Because sealed beams have been used in these applications successfully for many years, Table 3 is provided as guidance for typical lighting installations. If newer technology lighting will be used on an aircraft, the light
pattern produced by the sealed beam technology can be used as a basis of comparison.

Runway Turnoff Lights

Runway turnoff lights are used to augment the taxi lights on large multiengine jet aircraft when taxing. They are typically aimed to the sides of the runway to illuminate runway turnoff areas. If using sealed beam technology, see Table 3 for examples of commonly used sealed beam lamps. The landing lights are normally switched off while taxing to conserve the lamps and to avoid blinding oncoming traffic.

Recognition Lights

A recognition light function may be produced by steady burn or by flashing the landing or taxing lights, or by using lights provided specifically for recognition.
