Is the application of full/calculated take-off thrust on the brakes a common take-off procedure for these jets? It makes me think the crew felt it was going to be tight from the off.
only if you’re runway limited. Usually a rolling takeoff if available runway exceeds BFL buy a good margin. BFL in the AFM are computed using T/O thrust set before brake release.
From my copy of the 900EX AFM, “Full takeoff thrust is set before brake release.”
Section 5, subsection 150, p3. Additionally there is a T/O CONFIG warning light on the MCS illuminates if:
Flaps more than 22°
Airbrakes not retracted
Slats retracted
Trim outside authorized range (-4.5° to -7.5°)
Park brake engaged
Uncommanded brake press in #2 system
this warning only triggered on the ground with at least one power lever > 82°PLA
accompanied by master caution and aural warn, “NO TAKEOFF” cannot be silenced as long as T/O Config is illuminated.
