If you lose Glideslope past FAF, do you have to go missed?

Asked by: 2082 views
FAA Regulations, Instrument Rating

I am a commerical student and had a question about instrument procedures. If you lose Glideslope past FAF, do you have to go missed?

I have heard that if you are before the FAF and lose glideslope, you should raise your minimums to non precision mins. However, past the FAF you should go missed. 

If you are past the FAF and go missed before the DA on a precision, would you climb to your initial altitude on the missed procedure, proceed to the MAP, then execute the missed instructions? 

 

Thanks!

    You don’t “have to.” It it’s generally a good idea to go missed. (I’ve made the switch to a LOC only once.’

    Yes, I would climb.

    If you were in IMC what altitude would you climb to? Initial altitude climb on the missed instructions?

    The initial altitude on the missed is to avoid a turn while too low. It’s not a level off point unless there is a charted altitude limit (see the BFI ILS 14R for an example).

    So, I’d just start climbing to the top missed approach altitude, although I’d wait until the MAP before making any turns.

    If you included the “what if” in your approach brief, and discussed the LOC only minima (if they are even charted), then continuing to LOC only minima is acceptable, and would be expected in a commercial environment.

    If you are in single-pilot ops, then you might want to reconsider this decision, depending on your experience.

    I would also vary this decision based on reported weather or availability of an auto-pilot.

    If it was a check-ride, then this should have been briefed as a possibility.
