Time required on LOC (NON Precision)

Asked by: 3415 views Instrument Rating

How to determine the time required on LOC (NON Precision) when we fly difference category of aircraft?  

For instance, on the LOC approach RWY 6L at LAX with Cessna 172 the ground speed should be 90Knots and the time 3:24. If I am flying Boeing 737 and my G/S is 138knots what is the time from FAF to MDA?

    If you were flying a 737, you would have the MAP available as a fix in the FMS and would not need to worry about time.

    However, it appears that use of an E6B is no longer being taught and you wish me to perform the calculation for you.

    5.1 NM @ 138 knots will take 2 minutes and 10 seconds.

    E6B nothing. Seems 7th grade algebra is no longer being taught.
