[a] 

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. 

(1) 

I

ntermediate. Use steps 7

3

6a1(a)(1) thru (6). Do not correct the IAF or IF when using individual 

segments method. 

(2) 

Final. Use steps 7

3

6a1(a)(7) thru (10). 

(3) 

Missed Approach. Use steps 7

3

6a1(a)(11) thru (13). 

(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.
