JENKI: 12000 + 500 = 12500 ft.
b.
Temperature Compensating System: Operators using a temperature compensating RNAV system to make
altitude corrections will be set to the current airport temperature (
−
12
°
C) and activated prior to passing the IAF.
A manual calculation of the cold temperature altitude correction is required for the MDA/DA.
1.
Individual Segments Method: Missoula requires correction in the intermediate and final segments.
However, in this example, the missed approach is also shown.
(a)
Manual Calculation: Use the appropriate steps in the All Segments Method above to apply a
correction to the required segment.

I
ntermediate. Use steps 7
6a1(a)(1) thru (6). Do not correct the IAF or IF when using individual
segments method.
(2)
Final. Use steps 7
(3)
(b)
Temperature Compensating System: Operators using a temperature compensating RNAV system to
make altitude corrections will be set to the current airport temperature (
−
12
°
C) and activated at a point needed
to correct the altitude for the segment. A manual calculation of the cold temperature altitude correction is required
for the MDA/DA.
