In the two aircraft types I have flown, 727 and 737-200, the recommended rotation rate was 3° per second. The 727 had tailstrike potential but on the 737-200, it was much less likely.

I was reading an accident brief the other day(for a DC-9-10) and found this interesting quote...


"Normal DC-9 Series 10 operating procedures advocate an approximate 6° per second rotation rate. The 6° per second rate of rotation can result in higher than desirable angle of attack as the airplane becomes airborne. The Safety Board believes that a 3° per second rotation rate of the DC-9 Series 10 airplane should be specified when icing conditions exist. The same procedure was applied to Boeing 737 airplanes after a number of them experienced “wing roll-off”(partial stall) at liftoff in icing conditions."

I have never seen this mentioned anywhere else. Is it still a 6° rotation rate on the short DC-9's?

Anyone have old 737 manuals(on the net perhaps) that mentions the 6° rotation rate?

I looked at the Air Florida report but nothing is mentioned about it.
