Good morning all...

"In the forecast conditions, the icing clearance would have allowed an IMC pull-up from low level to Safety Altitude over the Mull of Kintyre."
You will note that there are no caveats whatsoever to that statement.
here's one caveat for you dear caz:
The emergency safe alt
and the leg safety alt (based on a 15nm or 25nm 'lozenge' around the leg to waypoint B - the one to which the nav kit was referenced) was, in fact,
6500ft or thereabouts. With a transition altitude of 5000 ft, a low RPS of about 1000mbs and a correct quadrantal, that gives the minimum safe flight level as FL70 - somewhat above the icing level, don't you think? That is the
minimum FL I would have flown if I had aborted from LL and was IMC in that part of Scotland. However, it is patently obvious that this option was not available to ZD576 because of the icing restriction and why a 'cruise climb to 2500ft' was a ludicrous suggestion for the BoI to make.
