BOAC :yes, in case of retracting flap directly to 1 you should increase flap at vref30 +20kt,or vref 15 +5
This ideea of going from flap 30 to 1 in case of engine failure on final,followed immediately by GA,is what can be understood from the last ammendament of the FCTM of the 737 (5.31 oct31/2003),as I said before.
We've tried it in the sim ,flaps 15 and also flaps 1 direct,and there are different feelings about both procedure.
My question is how you do it?
From your answers I get is : eng fail-GA- flaps 15,speed vref 30+15(20). This is how we do it,but from the FCTM I understood diferently,and I was trying to find out how others do this.
