PR9 take-offs
90% was the standard rpm for take-offs. I can't remember the safety speed, although it might have been 180kts. We did a det to an airfield in a hot country where the there was no barrier and the over-run was very strewn with boulders. After some discussion, we decided on 100% take-offs. The safety speed was much higher (220kts IIRC). At max operational AUW, the event was rather less comfortable than a normal launch for me, sat in my cupboard up front.
