Hey guys can somebody help me please ??
which part of the wing stall first on 737 swept wing?
is it root or tip first?
i know a simple swept wing stall at tip so what has been done to 737 wing to stall at root first?

Ash heres a question, What do you think they have done to prevent stalling at the tips first?

Put more vortex generators out there...energises the airflow and delays separation.

Have u seen those STALL strips on the LE Flaps?

Yeah, it probably has nothing to do with that twist in the wing that lowers the angle of attack at the tip...

There's a large vent opening under the wing tip that, when approaching the stall at the wing tip, bleed air is blown towards the tip to energise the vortex and avoid flow separation. So someone told me in a bar long ago after my inaugural 'walk-round'. Please don't tell me they were kidding.

It's all PFM.

Thats hilarious, now I know what I will tell the next newbie during the first walkaround :D
Given that a simulator is just that : a simulator, the next time you are in one I invite you to try the following.
10,000 feet, 250 KIAS, close taps, pull back smoothly to 45 degrees nose up and simply let go of the prong.
The result will give you great confidence in the design, and remind you that, while, (in relative terms ), the B737 is a reasonably slippery airframe, it is just another airplane.
No vices ; what you see is what you get. No tricks or traps. Good fun to fly.
Enjoy !!

That assumes the simulator is programmed with the correct data for the resulting manoeuvre. Simulators are good up to the point of stall - thereafter they may not be entirely accurate.

Both AB and Boeing say simulator modeling does not accurately reflect real a/c performance at the edge of the performance envelope and stalls in the a/c are more violent than the simulator models.

Spot on! That is why upset training is so difficult to do on the simulator. It can lead to unrealistic expectations of the real aircraft's behaviour and misplaced confidence in the pilot's ability to control the resulting manoeuvres. Trainers need to be very aware of the limitations of the simulator's ability to replicate the aircraft.
