Dear Paul! You can see comparison with FCTM: post #20 http://forum.avsim.net/topic/345401-final-approach-attitude/page__view__findpost__p__2075807

I confirm. Zero degree on final approach with Vref+5. There is a problem. But the developer does not want to admit it.

I have pressed.

Roger.

Low dependence.

Dear Sir, I have installed all hotfixes.

It is not normal Sir. And I'm trying to draw attantion to this.... And one problem more: http://forum.avsim.n...ruise-altitude/

Are you shore? Almost 2000 feet?

Hello! I have one more question. Before I asked about approach attitude. Now I have to note my observations for Optimum cruise altitude. So, flight URSS-DAAG. Boeing 737-800. Abt 1800 NM. 17 tonns of fuel, 4 tonns of cargo and 147 passangers.Gross Weight = 74.0 tonns : Ok. TSO914 climbing FL360... Reached FL360. Optimum altitude and TAT: Gross weight: FCOM: [ Difference is 1800 ft - too mach. Who is wrong? Please check it.

Hmmm. If you mean PMDG 737NGX can you show any screenshot of your approach?

Exactly Sir. I mean Attitude is zero. Of course AoA is abt 3 deg for my situation.

Realy? May be Boeing 737 FCTM is not realistic?

The result must be 2.9* for GP 2.5* and 2.4* for GP 3.0*. And not otherwise.

You are wrong Sir. Everythings updated. And 64.9 tonns is abt 143080 lbs, not 130000. And see again this picture:

Ok guys. I have made a new test. Airport ULAA. Pattern route. No any weather generators. No wind, no gusts. Gross Weight = 64.9 tonns, Vref30 = 148 knots: Compare with FCOM : Excelent! Flaps 30, IAS is Vref+5, attitude is abt 1 degree and vertical speed is only 400 ft/min: Ok, ILS approach 08, autolanding : 240 ft: 80 ft: Flare, 1 sec to touchdown: Sorry for this long story. One more picture from FTCM: Thanks. Great aircraft! But please check this situation.

You are wrong Sir. 20 sec later, vertical speed = 800 ft/min : Attitude is zero. And I say again: this is not my video: http://forum.avsim.n...uring-approach/. See from 06:12. I have the same problem with the approach attitude.

Ok Sir. But as far as I know FMC is recalculating Vref speeds all the time according actual weight and fuel consuption.

Good idea! I'll try that in few hours.

See CDU display on the screen. Actual calculated Vref is 141 knots.

Thanks for reply. But you can change this on your system in any airports with glideslops 2,5 or 3 degree. You will see same attitude - zero. This is not correct.

Hello! I thought that this problem only with me. But I have watched this video http://forum.avsim.n...uring-approach/ and undestood that everybody has it. What I mean? See this video from 06:12. Vref30=141knots. IAS=146knots (Vref+5). Flaps position=30. Vertical speed=900ft/min. And... Attitude=0 degrees. According to FCOM, attitude for final approach with IAS=Vref+5 must be more then 2 degrees.Dear PMDG Team, could you chek it? Screen from that video:
