Warped factor, thank you very much for the link to the AIC 36! I've printed it out and put it with my papers, info I have never seen before.. .. .And EGLL is really overcrowded, receiving the landing clearance below CAT I mim last night was a close call... without being advised of late LC <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> . .. .Nobody ever stated the final reserve fuel fur the 747 in this thread. As long as you land above FRF I don't see the problem. You land below, emergency must have been declared. Did they?. .. .Cheers
