4.3.5.2.2 Determination of minimum promulgated temperature. Determine the minimum probable temperature (the temperature correction is obtained from Appendix A to this chapter) and round it down to the next lower 5°C increment. Then:
a) the FAS for that temperature shall be calculated (see 4.3.5.2.3) and, if less than 2.5°, the promulgated VPA shall be increased to ensure the FAS at minimum temperature is equal to or greater than 2.5°; and
b) the length of the preceding segment shall be reviewed to ensure it meets the relevant requirements for minimum distance before vertical path intercept.
Note 1.— One suitable method of obtaining the minimum temperature is to obtain the mean low temperature of the coldest month of the year for the last five years of data at the aerodrome elevation. Round this temperature down to the next lower 5°C increment for promulgation. Obtain the cold temperature correction applicable for this temperature, the aerodrome elevation, and FAP height using the criteria in the appendix to this chapter.
Note 2.— No minimum temperature restrictions apply to aircraft with flight management systems incorporating final approach temperature compensation.
Note 3.— No minimum temperature restrictions apply to aircraft with flight management systems incorporating approved final approach temperature compensation, provided the minimum temperature is not below that for which the equipment is certificated.
