I would guess as ab33t says, having reduced to CLB power with "N1 - 210/20/30" for accel, when clean at the bugged 210/20/30, the next call is 250 for the climb speed limit?
"Press the N1 button (or VNAV if appropriate), verify that
N1 Limit
annunciates CLB and that climb thrust is set........
~~~~~~~~~~~~
Complete the flap retraction and, maintaining a constant pitch attitude,
accelerate to appropriate climb speed.
Do not exceed 220 kts until the
leading edge devices are retracted."
and
"If the Flight Director is used,
at Aa the Handling Pilot should call for:
"VNAV", which will automatically provide Climb N1, or
"Climb Power,
xxxKts" and follow the pitch commands which will give the correct
acceleration during flap retraction."
"Climb Power," is most easily achieved by pushing 'N1', LVLCHG being initially inhibited.
mistakenly thinking that the thrust is at take-off power while TOGA is being displayed
??? - what is it at then?
