Airport /Heliport APAPI and Heliport PAPI System Precision Approach Path Indicator providing visual glide slope guidance for flight landing

- April 23, 2020

Annex 14 to the Convention on International Civil Aviation – Aerodromes Airport Lighting APAPI and Heliport PAPI System Precision Approach Path Indicator

Approach Light Systems provide the basic means to transition from instrument flight to visual flight for landing. Operational requirements dictate the sophistication and configuration of the approach light system for a particular runway.

PAPI (Precision Approach Path Indicators) primarily assists by providing visual glide slope guidance in non-precision approaches environment.
These systems have an effective visual range of at least 3 miles during the day and up to 20 miles at night. The row of light units is normally installed on the left side of the runway and the glide path indications are as two red and two white (2 red 2 red) when on proper glide path angle of approach. Light combinations indicate when slightly high (3 white 3 white), significantly high (4 white 4 white), slightly low (3 red 3 red) and significantly low (4 red 4 red ).
