Portable PAPI
The portable (or Tactical) PAPI is the direct result of Research Engineers collaboration with Air Forces under operational conditions. The emphasis of the design is on portability, rapid deployment and ease of maintenance. Suitable for both civilian and military use, the Portable PAPI is a standard NATO stock item.
Two units, each with two projectors, have been found to be entirely satisfactory for landing all types of fixed wing aircraft in APAPI configuration. Operational experience shows that 100 watt lamps are adequate if the equipment is used predominantly at night. Slope angle is set quickly and simply using three legs. The front legs level the unit laterally whilst the rear leg provides the elevation adjustment.
