The report states that Rolls Royce were happy that there were no JPT or thrust anomalies on take-off for the accident sortie. There are clear statements of the JPT reading on take-off and during the accident manoeuvre, showing that the JPT on take-off was significantly greater than during the accident manoeuvre and within the normal range (580 - 690 C).
The Pilot's Notes state "Ideally, ease the nosewheel off the ground between 115 and 135 knots depending on configuration" and "Depending upon weight and attitude, the aircraft unsticks between130 knots and about 155 knots". On airtests, the take-off is performed initially with full back stick to check the minimum nosewheel lift-off speed; for this configuration it is usually about 105 KIAS.
Falcon900,
If the ground roll was greater than expected and the end of the runway was getting closer, even if below the normal nosewheel raise speed I think that some pilots may try to take-off at a slightly lower speed than normal.
