Can a failed Glide Slope also void the Localizer approach?
but perhaps if you examined the BFI ILS Rwy 13R
approach, or the KMSO ILS RWY 11 approach, you would understand.
Well, maybe I'm thick, but I don't understand. True, you need to be
prepared to switch (i.e. have the chart handy, have the DME tuned
properly) but I see no reason why a properly prepared pilot could not
switch. True, you may be below the stepdown fix when you lose the GS,
but if you don't go any lower, you won't hit anything (the GS has
already provided obstacle clearance) and you should be able to fly your
present altitude until the next stepdown.
Or... set up for the LOC, but fly the GS if it's available.
I'm looking right now at the BFI ILS 13R and the LOC/DME for the same
runway.
