Beta 4.5 - Excellent performance!

Recommended Posts

I just made a short flight to test the LPV approach fix. Using the RXP GTN750, LPV glideslope capture and descent was very stable - no tendency to oscillate in pitch as before. I goofed initially, and forgot arm APPR on the autopilot, so the aircraft flew through the descent point. I used the new TCS function to pitch down a bit to re-capture the LPV glideslope, then enabled APPR, and the aircraft descended just fine from there on in. It seemed as stable as the corresponding ILS approach to the same runway.

But, the most substantial improvement by far (IMO), was the reduction in the drag parameter for slats. I initially deployed them in level flight while maintaining 180 knots IAS. There is no longer a "hitting a brick wall" effect as before, where the airspeed would start to drop substantially as soon as slats came out. I found that a slow and steady 12 percent increase in N1 was sufficient to hold 180 knots. (I was lightly loaded at GW of 29,500 pounds).

The slats drag fix has also improved the aerodynamics when deploying flaps and gear later on in the approach. An increase in power is required of course to counter the increased drag, but much less than before. Previously I found it necessary to add a lot of extra power when deploying flaps and gear, and due to the delay from engine spool-up time, I would end up chasing airspeed to keep it stable at VAPP. It is ever so much better now. Nice job!

Hi Jim,

A most excellent PIREP... Very encouraging... Yeah - while I've never flown anything larger than a Duchess - - - it did seem draggy from flying other bizjets in FS - I could fly some incredibly steep STOL like approaches in this bird... Sounds like an improvement...

Regards,
Scott

Hi Jim!

Did you update P3D to V4.4? I updated the Client only and installed the V4.5 of the Falcon 50 and all I get is a black screen with CTD(idem with the Lear 35). I use the  F1GTN which I updated to V2.07. So far all the other planes(CaptainSim 757 III, PMDG 747, 777, DC6 with GTN650)work flawlessly except the Flysimware. I'm very eager to know your answer also the one of other people who updated P3D to V4.4!

Regards

Hi Pat

Great Report. This plane keeps getting better. 

Could you summarise target approach speeds for us please? 

Thanks.

Hi Pat, just carried out a flight ( similar to Jim) using Prepar3D 4.4 and the flight1 750gtn ver 2.07 and it went well. that's with ver 4.5 for the f50.

I haven’t updated my sim to 4.4 yet. I’m waiting on the Rex/Milviz weather radar to be made compatible. If they don’t update soon, I may have to uninstall it temporarily, because I really would like to try 4.4

I am running the updated P3D 4.4-compatible versions of the RXP and F1 GTNs - but still in 4.3

I use the RXP in the Falcon, and the F1 in the Lear.

Thank you onebob and Jim, may be the cause of the problem is the weather radar, I forgot when I updated to V4.4 that it's not yet compatible with this version of P3D.

Cheers

I uninstalled the rex/mv wx radar and just have a blank screen in the f50,

Yes, from what I read, the Milviz radar in its present version will definitely cause a CTD in P3D 4.4 if loading an aircraft that references it.
