Question for EDI controllers

[Flap40]

Any Ideas wht the min radar vectoring altitude for 24 is (mostly) 2300ft but the ILS & NDB approaches have a platform of 2100ft? It makes no difference to us for the ILS but it can make it very difficult to find the descent point on the rare occaision that we get vectored for an NDB.

An excellent question!

The 2100' restriction is for noise abatement minima. The RVA chart allows for descent to 1700' within the final approach area, but if vectoring that's not much use (as we can't give you that level until it's too late!). Personally, if I'm vectoring for the NDB I'll generally give you "turn left heading 280, cleared NDB approach 24" and you can do whatever suits you regarding descent. Many pilots will descend the extra 200' straight away, then commence final descent at 6.1d as per the plate.

Where the 2300' figure comes from, I honestly don't know.

Sounds a bit like what happened at Sunny Sumburgh last year.....

Someone built a 100ft mast on top of a hill 5nm N of the airfield. RVA minima subsequently ammended from 2000ft to 2100ft within 5nm of the mast....which happens to encompass the airfield and approach aids (VOR and NDB). However all approach plates still give MSA and Initial Approach level as 2000ft!!!

I have given up trying to find an answer... <img src="rolleyes.gif" border="0">
