Fuel used from Desdi
Just out of interest; after exiting the Desdi hold the other night I noted the fuel used from crossing Desdi at 10,000', flying the arrival 30R with the usual minor extension downwind and reduce speed/early flap, to touchdown was exactly 2 tonnes. This was in 772 and as has been pointed out the FMS does not give accurate predictions in this situation. Wouldn't want to leave Desdi with less than 5 Tonnes or 5.5 in the 773. This gives about 25 mins holding to land with a 30 min reserve.
What do you guys think?
