Default Intercepting the ILS

Were you timing the approach as well for when the GS goes out of service
as they sometimes do on IPC rides? the timer should start at the FAF
which can be a busy time if you're going down, staying centered,
maintaining airspeed, calling the tower at FAF if that's what they
wanted, etc.



The Final Approach Point (not fix) on an ILS is the published
glideslope altitude (in this case, 1800) intersecting with the
glideslope. That's NOT where the timer for a LOC approach would
start, because there's no glideslope to define the point!


In this instance there's a 5.3 DME defining the FAF, and the Outer
Marker it's 4/10th of a mile from GS intercept. It's a busy time. I
didn't say he started timing at GS intercept at 1800, I believe I did
say at the FAF. With an IPC you expect things like GS's to fail which
adds to the workload. Thats all I meant.
