Out of touch I am
Currency is everything - but, a passing question . . .
If you force tuned a VOR or NDB say, and the FMS already had a nice ILS all set up and working with ILS pb APPR too - could/would this (force tuning the other aids) . . . disengage the operating in range LOC/ILS and mess things up a bit?
I would tend to want to force tune what I had, as a back-up, if at all, rather than something - I may want in the event of a G/A or whatever. What am asking is: would it detract from what was already set up in the box and on the PFD and the NAV map. Because I thought to force tune would over-ride what (it) had auto-tuned?
