GM8 CAT.OP.MPA.110 Aerodrome operating minima
CAA ORS9 Decision No. 47
Text in magenta in force from 30 October 2025
LOW TEMPERATURE CORRECTION
-
An operator may determine the aerodrome temperature below which a correction should be applied to the DA/H.
-
Table 20 may be used to determine the correction that should be applied.
-
The calculations in the table are for a sea-level aerodrome; they are therefore conservative when applied at higher-level aerodromes.
-
Guidance on accurate corrections for specific conditions (if required) is available in PANS-OPS, Volume III (ICAO Doc 8168) Section 2 Chapter 4 First Edition, 2018.
