Possible Bug:
250/10000 speed restriction not honored (during cruise phase). 757 and 767
Flight Phase:
Level-off to cruise (below 10,000ft)
Manual Reference:
No manual needed
Issue:
When cruise altitude is below 10,000, at level off, the CS 757/767 ignores the SPD TRANS of 250/10000 and accelerates to cruise speed (well above 250KIAS).
Can any one with a little more real world experience chime into whether or not it's a bug? It's not written in my airline manual anywhere at all, I've read all the VNAV chapters today and no clue, it's rare you'll be in CRZ phase below 10000 (except lately lots super short of repo flights IRL!), but now I wonder. I know every other plane I've flown IRL has honored any climbing restrictions to cruise if the restriction is lower than the cruise speed.
