Hi fellas,
Flying the PMDG 744 and, as you know, it flies clean at well over 250 knots under 10,000 feet, how do I get that 250 knot restriction waved?
Cheers.
I would have thought that the 747 would be able to fly clean at 250kts. Are you particularly heavy? The 250kts rule at 10,000ft is initially an FAA regulation though it has been adopted by many other authorities. That said the "No speed" restriction is given only on departure to facilitate climb to cruise etc. Arriving the general idea is to slow down!!! So ATC would not give a "no speed" restriction as it would destroy aircraft separation in a nanosecond!
Currently the "no speed" restriction in PF3 is a random event. I'm not sure if it is purely random or whether some criteria is applied first.
I would have to say that in your case if you are descending from 10,000ft you should be thinking of slowing down. Climbing however the 74 sould be able to maintain 250kts easily. It also depends on the SID as well if there are any SID speed restrictions.
Another point with the 747 on climb out is, especially if it is at auw, is rigid adherence to the flaps retraction speeds. The a/c at auw is going to be a bit sluggish anyway and if you retract flaps too soon even more so! From a video point of view the best example I have come across is Oh and stating the obvious make sure that in option1the Just planes Air Atlanta Icelandic video Luxembourg Singapore Kuala Lumpur Baku Luxembourg. I listed all that because they did a couple. Anyway on take-off from Luxembourg the 747 is about 100kg below auw! The PO is flying exactly to the flaps schedule so much so that the Captain comments on it!
