Thank you gentlemen.
Hans,that is something I didn't know,I will try that.
Tom,I have both TTools and ADE.
TTools I am rather familiar with,I think.
ADE,I have not played with yet.
The version of RAF Valley is in the "Just Flight" British Airports,Volume 5,Wales & West Midlands
(the North West Mids is where I live),Shawbury,Ternhill and Cosford are the closest military airfields for me,we holiday a lot on Anglesey (in Wales)so I like to visit Valley quite often.
I assume the JF airports are editable with ADE(they are with TTools),so I'll try Tom's idea of deleting and re-adding the ILS.
*Addition*
I've just run ADE and checked the ILS information.
It seems that Just Flight have aligned everything on the Fs9 Valley.
ADE tells me that (in red)the ILS is stock,the delete button stays unlit,so I assume that it's not "editable" by deletion and re-addition.
It does however tell me that the ILS "beam" has a range of 30 miles,a width of 4.4 miles and a
3 degree glideslope.
Any other ideas?(apart from Hans changing the wind prior to launching)
