Hi All,

I spent this night in the sim.At the end of the section we still had 30 minutes for free time.
I asked the instructor to level me off at the optimum level for the weight we had , (205T), which was 37000 FT.
It was tested in a new simulator.

I disconected ADRs 2 and 3 and I wanted to force the airplane into stall.

General Impressions:

1.It entered in full stall at around 40thousand feet , well into the red line.

2.To force it into stall I was using a pitch up of between 15 and 20 degrees of pitch and climb thrust.

3.Just before stalling the airplane pitched up by almost byhimself to 30 degrees.

4.It then started sinking R/D between 10 and 15000 ft/min.

5.Then I pushed the side stick full forward and kept it there. NOTHING. Interesting to note that I was maintaining pitch 10º Down , but it never got out of stall.

6.At around 26oooFT I reduced the thrust to get a pitch down moment.

7.It never recovered from stall until the instructor freezed the sim at 4000 feet.

8. Tried the same again. The same happened.

9.Leaving the sim , I met a coleague , very experienced on the A330 who told me thre is a trick to recover from stall. Set manual pitch trim to full down. I didn`t tried it. Maybe next time I have some free time again.

Conclusions:

1. If the sim really reproduces the airplane behaviour , the AF447 was is deep stall and they would never recover.

2.I had never heard about trimming down the airplane.So the crew didn`t for sure.


Your opinions.
