Low noise??
Well, the goal of the exercise is to burn fuel at a reasonable high rate in a hold with minimum fuss.
So how about hold below 10 000feet, say 4000 feet, 230kts with 2 minute legs or greater , gear down flap 5 should give reasonable high fuel flow and not to much noise.
No clue about the total fuel flow at that speed an configuration as I never had this issue, but a clean hold at 4000 and up speed plus 10 gives ca 2200kg burn per hr for aircraft 65 ton or less.
So a 70 ton aircraft at my configuration would tip 4000kg plus ,I figure.
Total wild guess.
Tell You what, I put it on my list for the sim next month , time permitting. ( Mind You a lot of Max vs -800 stuff I want to test first)
