Thanks for that and one final question. Is there a detailed FMC programming guide included with the iFly model or do we need to buy something else?

The manual is comprehensive - 500+ pages worth; there is also a QRH and tutorial. All in all, it's a very good package. DJ

Considering the PMDG 737NG is roughly 5 years older than the iFly series, it would seem obvious that the iFly is a much better purchase than the PMDG model. I really do recommend the iFly for FS9 - it's very good.

Technically PMDG is nbr 1. Graphically iFly is nbr 1.

Technically PMDG is nbr 1

Just out of curiosity, not to provoke any dispute, but what exactly is technically superior in it over iFly?

the least that I can say is that PMDG Performances meets the real Airplane CLB/CRZ etc as well as the fuel consumption, if you can manage do a flight with a real flightplan with both of them, then you will be able to say if am right or no, dont wanna talk about some other details about the auto system behaviour as well.

The ifly 737 feels too sensitive through the joystick for my liking. Maybe I'll have to adjust some settings somewhere. I already have adjusted it in my styles. The PMDG felt a little more heavy on the controls which is what I've heard the real aircraft is like - any aircraft really. I could use more joystick movement with the PMDG which felt more natural.

At last somebody that has my same opinion ! See this post in this same forum: http://forum.avsim.net/topic/343106-reducing-rudder-sensibility/ And what I have modified in the IFLY-737-800 to make it less sensitive: Ok, I modified the aircraft.cfg file for the IFLY 737-800 in the [flight tuning] section:rudder_effectiveness = 0.50 // it was 1.00elevator_effectiveness = 0.70 // it was 1.00No FSUIPC calibration.FS9 Joystick sensibilities about 25% (except throttle 100%) with a small null zone.From being a jerky aircraft, now it behaves like a charm and hand flying it is a total delight, having the stable and soft movements that (I presume) an airliner should.signed: José Luis

Well, I finally got mine to work. Over all I'd put ifly ahead, but not by much which some may say is a big call. The 2d cockpit is visually a lot better. I never cared for the VC is any aircraft so I wont comment. Graphics, visual appearance, moving parts on external views etc etc etc mean jack squat to me. I look to the FDE as the deciding factor in everything. Which is why we all love add-ons like the Level-D 767, PMDG 747, aeroworx B200 etc. The ifly 737 feels too sensitive through the joystick for my liking.

The PMDG felt a little more heavy on the controls which is what I've heard the real aircraft is like - any aircraft really. I could use more joystick movement with the PMDG which felt more natural. The iFly model does seem to reach the cruise altitude numbers from take-off - distance flown - closer to the real thing then the PMDG( using boeing documentation). But in descent, the iFLY seems too slippery for my liking. At a .79/300kt descent, even planning for 3 x height + 20 was too close(zero wind, 250kt below 10,000). Plus 25nm would be closer to the mark. PMDG's 737 I could get down using 3 x height + 15. Evidently most real pilots use 3 x height + 10 for the similar aircraft - 737-800 in all these tests. But if a real pilot wants to correct me, please do!! The iFly spoiler is WAY to strong. From some of the numbers I've seen regarding the real thing, PMDG seems way closer to the actual thing. Especially below 250kts the real aircraft speedbrake isn't much help as is the PMDG 737. iFly's model will double the descent rate which is too much. The iFly 737 doesn't always hold the numbers in vnav mode. It'll bust the speed often. Whether this is realistic anyway, I don't know. Personally, I'd prefer the iFly for sure. Some aspects of the PMDG I'd like in the iFLY. But for the time being, iFly is number 1for me.

It's supposed to be slippery - check out the new 737NGX model as an example; iFly catches that well. I haven't noticed control sensitivity and suspect it may be the controller rather than the model - for me it's been stable. Got to admit I've never busted a vnav number either; remember that the speeds are not absolutes unless you enter them - if the a/c has computed them they are approximations. DJ

Interesting... I've flown the actually real Level-D simulator here in Eagan and from my experience iFly nailed the FDE on all counts... I can't speak for the PMDG version as I'm an FS9er. All I know is PMDG got the roll sensitivity wrong in the 744 based on what I experienced in the real 744 simulator... The roll delay in a 744 has to be experienced to know what I'm talking about here... It's funny to read people changing FDE entries to what they assume the aircraft should fly like versus reality...

Les, they're talking about the old FS9 PMDG version!

From my experience in the Leved-D sim that pilots train with iFly is the next best thing to being in the real bird.

Oops, thanks... I just wrote a little note to iFly commenting on their VC and thanking them for their effort. I like all the advances in the PMDG model but iFly nailed what it's like in the flight deck. For one if the pilot is sitting correctly in the cockpit his eyes is not that high over the glare shield. Before anyone comments I've not only sat in the real cockpit but also flown the Level-D simulator. I wish I had photos of it (already posted shots of me in the 744). I'll take some pics the next time I go if I get the chance again...
