ED Decision 2023/007/R
LOW TEMPERATURE CORRECTION
(a) An operator may determine the aerodrome temperature below which a correction should be applied to the DA/H.
(b) Table 20 may be used to determine the correction that should be applied.
(c) The calculations in the table are for a sea-level aerodrome; they are therefore conservative when applied at higher-level aerodromes.
(d) 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.
