Never 2, though; that must have been some huge ground speed at rotation.
- not so frightening, and certainly no worse than Improved ('going like a train') speeds - Flap 1 common for Classic take-offs where obstacles were the primary concern, but abandoned on the 737- 400 due to tailstrike risk. Used also on 200 and I assume 100. I was told it dated from 727 or even 707 (or even B17.......
) from which the flap gate (and gear lever?) originates and rather than re-machine the whole thing Boeing left the gates as they are. If you use it, use the F1 manoueuvre speeds as I don't think any are published.
