Site Requirements
The PAPI should be placed near the runway in accordance with the specifications from the
applicable regulatory agency, for example FAA or ICAO. The PAPI is placed to the left of the runway
as seen by the approaching aircraft across from the touchdown zone. The location is determined based on
the type of aircraft, the grade of the runway, the nominal glideslope angle, and the height of the LHA above
the ground. As an example, Figure 4-1 illustrates some of the specifications from FAA AC 150/5340-30d.
Note that the site requirements are more complex than illustrated in this figure as they must take into
consideration the aircraft type, the grade of the runway, and whether or not there is an ILS. In addition,
there are different rules for a general aviation runway used by non-jet aircraft.
Figure 4-1.1: Diagram of the layout on the runway for PAPI Light Housing Assemblies (LHA) from
FAA AC 150/5340-30d. This is an example only, the installer is responsible for placing the LHA in
accordance with the specifications from the applicable regulatory agency, for example FAA or
ICAO.
