What does that mean?
We were at FL 300 and ATC said:
"When ready, descent FL 210, be at FL240 or bellow at 15 NM from ABC"
My CPT leveled off at FL 240 at 15 NM from ABC and waited there before descending to FL210.
I disagreed!
Up to me (but he could be right), he was not allowed to level off at FL240. He told me "yes, because she said "when ready"".
For me, when she said "when ready", this was to start the descend from FL300 to FL210 and to cross 15NM from ABC at or bellow FL240, and not to level off at FL240 and when ready descent to FL210!
What do u think?
