Actually you can land the 72 in a crab, I'll try and find the limitation, because to be honest I have forgotten the limit. I have operated the 72 in very strong cross winds with little trouble. On a few occasions full rudder and aileron application on takeoff was insufficient and I had to nudge the nose wheel steering tiller until the airspeed got over a hundred knots to stay on the center line.
The heavier the 72 is the easier to land in cross winds.
For approach fuel flows on final in landing configuration (flaps 30) on the 100 series at normal weight it seemed that around 3,000 PPH was the target setting, on the 200 series around 3500 PPH was needed. Set the power at those settings and then make minor adjustments to remain on the landing profile.
It is actually a very easy aircraft to fly. I enjoyed the 7,000 hours I have in the 727.
(Well, most of them anyway.
)
Oh, one note of caution. A lightly loaded 727, crew only and less than 10,000 pounds of fuel, will float like a Piper Cub on landing if you let it, so be careful when light.
