DONE - Landing pitch too high

On final, default landing pitch is too high (around 5 degrees).

Going into the aircraft.cfg, in the [flaps.0] section, increasing the lift_scalar value from 1.0 to 1.45 seems to improve this, giving a value of 2.5 degrees (using flaps 30 and correct Vref speeds) which should be correct according to Boeing manuals.

2.5 seems too low, that number is used for VREF+10 in unreliable airspeed condition.
According to FCTM, 3~4 is the range for a normal VREF+5 approach.
CS's 5drgree is too high and noticeable in cockpit view, and still there in v1.0, hope it could get fixed.

Actually the highest value quoted in the FCTM is 3.2 for the -300 with flap 30, with 1.7 with flap 40. If you want to match these values as closely as possible, you can try lowering the scalar figure I mentioned by 0.05 at a time.

Cheers

Ah, I have done that with another 733(and 4,5) back to FS9 days and it took me days to complete all tweaks and test flights.

I believe that should be what I paid for CS to do now Huh
