I was caught out the other night becoming established on an ILS by forgetting to switch the gps annunciator switch from GPS enroute mode to NAV mode (light twin).
I'm sure many Pilots have done this before and I reckon that eliminating the ILS ident (navaid ident) when the instrument is in GPS mode could help the situation from re-occuring.
What are your thoughts? Is there a good reason why TSO'd gps' allow the navaid ident to be recieved even though you're tracking via GPS CDI (the position of the navaid) rather than the navaid itself?
