It was the standard recovery to self-navigate to the TACAN dive arc (actually a sort of cheese wedge) at Valley, then aim for Point Alfa. I think the dive started at FL185? Then whistle down at 300 KIAS with one notch of flap and idle power. Hopefully then visual to the aerodrome, otherwise change the offset to Point Foxtrot and thence the ILS to RW 14. Much more difficult in the Hunter without an offset box though.
One or two Gnat students set the offset for the VYL TACAN, but had dialled up the wrong TACAN channel - such as the POL TACAN. Diving down to break cloud somewhere over Manchester was a bit of a shock - as it was to the Air Traffickers!
Pretty simple; it's all changed now though.
