View Full Version : Small ILS Q
I would be grateful for an explanation as to the answer to the following Q.
Thanks in advance for your help.
Q: Under what circumstances would an ILS glide path in excess of 3 deg be used?
a) Where other means of obstacle clearance are impractical
b) For aircraft with STOL capabilities
c) Where noise abatement restrictions make a less steep approach impractical
d) Parallel runway operations
I would have thought answer a) obstacle clearance.
STOL aircraft can use greater than 3 degrees but they don't have to.
As far a I know noise abatement would not affect ILS angle and neither would parallel runways.

(A) I'd say.
Van Nuys in the USA have a > 3° GS angle to bring you in over the mountains as I recall......

I'd say a) too. Approaches to Bodrum in Turkey have a steep approach due to the surrounding mountains.

a) e.g. Prestwick runway 31 - 3.5 degree slope.

a) London City = 5deg. Pilots have to be rated accordingly.

Just a smidgin off thread, I know, but please forgive me.
Englishal, I like the piccie, it brings back many happy memories. I believe it's the biggest representation of a club in the world, isn't it?
F1 - totally forgiven - but Shirly, the biggest 'representation' of a club is West Bromwich Albion?
