    thx for your answer.

    Since that parameter / factor that associates an aerowing with the propwash is fixed, I guess it doesn't differ between upwind / downwind aerowings, so, it should be symmetrical during the takeoff run under x-wind ( ? )

    Anyway, I see the propwash vector can itself be affected by the wind, which influences other flight dynamics aspects, and that's good to know.

    How does AEFS2 FDM deal with x-wind situations regarding the deflected propwash from, for instance, an aircraft with it's prop ahead of the fuselage / wings taking off under x-wind ?

    Is the propwash deflection due to stronger x-winds, specially during initial full power takeoff run taken into consideration, with the "wash cone" being deflected downwind and hitting mostly the downwind wing and fuselage / tail sides, as well as taking it's "central core" away from the tail surfaces and reducing their efficiency during the initial takeoff run ?

    AEFS2 is the Perfect Simulator platform presently available to bring to live features ever wanted / requested by the big majority of the simmers after all, and in some ways already, like when we look at it's VR implementation and overall performance & smoothness...

    Well, I confess I couldn't give hand of my Condorsoaring v2, but my perspective for the future pretty much lays in the direction of AEFS2 evolution because it is the cleanest approach so far, not tied to old engines and idiosyncrasies and being built from scratch but with outstanding detail and quality.

    It's not a sim for those suffering from the typical disease of the XXI Century - Impatience and Consumism, totally forgetting to enjoy what is provided... and instead always focusing on what is not yet provided ...

    Thx again for yet another great video!

    It actually also shows a particular aspects where AEFS2's way of portraying reality, and one which is important for the realism / accuracy of the simulation, really needs tuning - the PAPI light systems.

    Their positioning, size and efficiency, as well as ( afaik ) there being just one type of PAPI and no APAPI, VASI or T-VASI although these are seldom used these days, are additional features I would like to see updated for upcoming releases.

    Indeed Herve - happened to me 2 times too :-/

    The first one was in 1982 when the first of the only two fatal glider accidents ever occurred in Portugal took place at Serra da Estrela, when a friend from Germany who was flying in Portugal for the season crashed in the club Cobra 15 against the summit when the glider entered a spin...

    Then when I as at Portuguese Air Force, I also witnessed a T-37 crash during a training session of the Portuguese Air Force exhibition team, killing it's pilot when one of the wings detached from the aircraft after he pulled at the end of a low pass...

    On both occasions it had quite an impact in me... I believe I love everything about aviation, less all being military / combat.

    Hope you can recover fast from that bad experience.

    All of the Best from here...

    Thermals that drift and cant with the wind due to gradient and friction, but also turbulence....

    Thermals that have an, even simplified, life cycle...

    Thermals that are possibly triggered by Sun radiation ( angle is important and a function of time and day of year, latitude, but also the type of terrain, which could be simplistically determined from the orthos...

    So many things I would like to have - the ideal would be something along the line of how soaring weather was modelled in my 3 preferred soaring sims, SFS PC, Condorsoaring and Silent-Wings...

    Nice update! Thx!

    Regarding the iddle thrust, if it now handles as described, for a considerable range of GW values, it is certainly more realistic!

    Regarding the 744 flight model update associated with throttle, I don't know what exactly it means, but I always found the 744 in AEFS2 a lot less sensible tha expected to thrust ajustments - the real thing exhibits very noticeable pitching moments due to thrust, which in good part accounts for the A/T being disengaged in the initial approach, unless it's fully automatic ( autoland )... I hope it didn't get even less pitching moments with the update ( ? )

    Well, currently I have nothing to wish for on te aircraft side. Eventually an agile Airbus longhaulr like the A330 would be great. Or the Boeing 777, which they are already working on. (767/787 are also great planes, love the sound on the 767

    People from other forums will surely know how important this is to you! 8);):thumbup:

    Of course Jeroen, that was what I meant to write, but missed - already edited :)

    Very few simmers care about that detail. I do, in every sim I use, and even my IL-2 Battle of Stalingrad/Moscow depict it perfectly ( including the correct Moon phase ) and DCS World does it too, although not so perfect in terms of Moon phase.

    But my IFR long used / preferred training sim, ELITE IFR, has been doing it in perfection since v7 ...

    The Q-400 in AEFS2 is actually IMH the most advanced default aircraft ever offered in any general civil flightsim I have used. The level of customization put, for instance but certainly not only, to the implementation of the Q-400 turbines is unique.

    People from other forums will know how important --> for me <-- the correct depiction of daylight and Moon according to date is :-). Well, even if AEFS2's Moon always shows the same phase when out of New Moon, it does get depicted with correct ephemeris and the daylight as a function of latitude - given that AEFS2 uses, by default, the PC date ( current ) is very good - tried it at various places on Earth just to check !

    Any Helicopter, and GAs, Cessnas, Pipers, Beechcrafts, ...

    Also the change to have glider being tugged by an aircraft.

    ULM would also be welcomed, and, of course ... WW2 airbirds :)

    I don't think I can get you ?

    You have a joystick, but are using buttons to control the ailerons and elevator, or are you saying you were unable to make the trim controls for pitch roll and yaw work ?

    Th Q-400 has noticeable torque effects at high power / AoA, requiring consistent use of rudder trim. Aileron trim should only be used in asymmetric thrust emmergencies, fuel imbalance, etc... So your main compensation / trimming should be done via rudder and elevator trim.

    Once set in the Controls menu, it's really easy to use in the Q-400.

    Can you be more explicit about your problem David ?

    AFAIK MSFS doesn't use a stabilizer trim system for planes that are supposed to have only elevator trim.

    It moves the CG and/or the aerodynamic center forward and backward.

    From the MSFS Aerodynamics Reference DOC -Source AVSIM ( by Yves Guillaume ), linked from:

    This was long confirmed to me by a good source, and by Ron Freimuth, with whom I had the honour to learn a lot about the MSFS internals....


    4.1 Elevator and Pitch Trim

    The main pitch control system in MSFS consists of an elevator and a stabilizer trim surface. The pitch trim concept is basically more the one of a moving horizontal stabilizer than that of an elevator with trim tabs. However, the additional lift and drag generated by the deflected stabilizer is not simulated in MSFS. Furthermore, the default autopilot only uses the stabilizer for trim and not the elevator. For consistency with the SDK the term Cm_detr is used although the elevator is not directly involved in trim.

    MS seems to have pitch controls designed for joysticks where the stick returns to a fixed center when hand force is released (such as most game sticks, e.g. Saitek X52). Zero hand force means zero elevator deflection in relation to stabilizer, so the stabilizer is the only trim surface.

    There are three components related to elevator and stabilizer trim: Stabilizer, elevator and an additional elevator effect due to stabilizer deflection.[...]


    P.S.: Sorry for the out-of-context message - this is an AEFS2 Forum... I know :-/

    @bbrz: it's MSFS that uses a stabilator-like modelling of pitch trim. In that simulator, when you trim in pitch, indeed the simulator assumes the whole HS moves, as if every aircraft was just like a typical airliner and most gliders, in terms of pitch trim.
