CAT111.
The prevailing runway at BHX remains 33 and unless winds prevent, aircraft have to state reasons why they want 15.
BHX has had 5 years of downgrading and upgrading of its ILS.
New ILS was fitted 5 years ago 15 end, then the following year on 33. Then 2 years when the runway extension was being built and the final year when it was moved back to the end of the extension.
Full CAT3 will be re-established on 33 when all the current cabling work and grass reseeding have taken hold.
