precision approach CAT I Operation down to minima of 200 ft decision height (DH) and runway visual range (RVR) 2600 ft. (When RVR is not available, 0.5 SM ground visibility is substituted.) Note: Rotorcraft visibility limits may be half those published for aeroplanes.

Fr: approche de précision CAT I
precision approach CAT II Operation down to minima below 200 ft decision height (DH) and runway visual range (RVR) 2600 ft, to as low as 100 ft DH and RVR 1200 ft. Note: Rotorcraft visibility limits may be lower than those published for aeroplanes.

precision approach CAT III Operation down to minima prescribed in the carrier’s operating specifications in the operator’s operations manual or in the Canada Air Pilot (CAP).

precision approach path indicator An approach path indicator system consisting of four light units situated on the left side of the runway (on both sides of the runway, in the case of the military) in the form of a wing bar. The aircraft is on slope if the two units nearest the runway show red and the two units furthest from the runway show white, too high if all units show white, and too low if all units show red. A PAPI can be situated so  as to provide three types of eye-to-wheel height (EWH): P1 (10 ft), P2 (25 ft) and P3 (45 ft).

abbreviation: PAPI
