Hi Globaliser.
A standard ILS slope is 3 degrees, Faleola is a standard airport in Pacific Paradise.
one degree is 108 ft per Nautical mile.
so 3 degrees is 324 ft per mile.
At 8 miles they were 970 ft instead of 2464 ft above MSL
The pilot flying and even the Pilot not flying should be cross checking DME with altitude.
The Pilot flying and the pilots not flying should take a note of the time of capture and the distance of the capture.
Lets Say @ 10 miles so its going to take about 3 minutes at 180Kts to get to the runway.
A mental picture must be present.
Never rely on only one indication of what you are suppose to be doing if another method is available to cross check
These guys had two other sytems, Time over distance and altitude over distance but they all locked on to the IAS ( who looked at the VSI??)
It goes on and on.
They all needed a Base check(180Day check)
Thats Basic instrument flying
Eh
