Falcon, very true comment!
I think the problem is the statement "unable"!
They cant say "we are unable" when the same aircraft in the same colours is doing it in front and behind them.
It would require a statement " I am" unable or unwilling to achieve the requirement.
I've watched people put the gear down, then wait for the A/T to increase, and then select slower.......a total waste of drag!
The 180 to 160 should be done ASAP. If it doesn't bleed off easily then bite the bullet and lower the gear, you've got drag, use it if you have to!
Energy Management.......if it doesn't come naturally, it has to be taught!
The CDA is another example!
