Pace,
Nope, haven't dared to give it a go I'm sorry to say. I've flirted with the VS function (vertical speed) and did a fairly decent let down through cloud over the sea, but close to an airport I prefer to do my approaches with the old six-pack and the Mk1 eyeball (and sadly yes, the only six-pack I'll ever have will be mostly powered by a vacuum pump).
kat - there's no way I'm going to ask! The fine people who provide us with our radar service out my way only know me by call-sign and I'd like to keep it that way - at least as long as this one is concerned.
