Will the 757 air file be included on all the 757's iFDG releases here shortly or just the Transavia livery?

Hi there,It will be included on the full iFDG release. I am modeling the RR RB211-535E4 model and with small mods, other thrust ratings will be provided as well. Be patient :)Iz

Iz, Seeing as how you're specifically modeling the RR-engined 757, and I was looking forward to flying my PW powered model, do you have any plans to model the different versions? I know that you fly the RR model in the real world, but perhaps the tweaks needed to mimic the PW2037s or the PW2040s would not be too difficult to handle. I am wondering if the only real factors in the aircraft's performance as far as FS goes would be the thrust ratings; any other changes would be too minor to worry about. But I'm far from an expert.Ryan Hoffman

Hi Ryan,Apart from engine acceleration differences and of course, difference in performance due to a different thrust rating, none of the flight dynamics need any changing. I think that the different shape of the PW engines hardly have an appreciable effect in performance and handling so that won't be a problem.Engine acceleration is also something I don't know much about, regarding accurate spool-up and -down times but this is too minor for me to care. I know that engine starts in our RR engines are rougly twice as fast as in Dutchbird's (Condor) PW engines, at least, a mechanic of DB told me. Still, too minor to even worry about, I don't think the engine start sequence is even programmable like that. So the difference in performance due to thrust ratings is just achieved by changing the engine thrust value. Drag, lift etc. is airframe related and stays the same.I did model the powerplant data to be used primarily with 767PIC, so that means that N1 values etc. are not modelled after real life values. For example, the CLB thrust setting may call for 105% N1 at a certain altitude while on our aircraft, it's only 98% under the same circumstances. In the FDE, it will be 105% so it matches the thrust rating on EICAS. As long as the actual amount of thrust and related performance at low and high thrust settings are correct, that's what I'm aiming for (and I think I've got it right now).Hope that answers your question.Regards,Iz

Iz, You answered my question and then some...thanks.Ryan Hoffman

You're welcome.Just tested my 757 on single engine performance. Engine failure right after V-1, single engine approach and go-around. She performs okay, not really up to the standard I'm used to but at least you'll stay alive, and without fighting for it :) It's too much effort to go and tweak all parameters again, I'd be busy for another month. Plus, it might be FS inherent that single engine performance on a two engine jet performs worse than in real life? I remember crashing and burning with some Posky 767's. Here we are on the ILS32 at KORD, autopilot coupled, works quite nicely.. :)
