Fed up



  • I am now getting fed up where is the ground power as now i have no power



  • @Moz154 The ground power unit and internal system is merely for display purposes and are activated via switches on the engineer panel, lower left side, where the engineer's knee would be - actual power to the airplane is via the master battery and avionics.



  • Nope nothing there can find it



  • Can't find what, exactly?



  • Dont matter i have uninstalled it wasted money on a plane i wont fly now



  • @Moz154 Concorde isn't massively complex, it's designed to be fairly simple to operate as long as the user reads the manual. I don't know quite what it is that you were unable to achieve?



  • The GPU can be activated by click the Ground Call switch which is located next the the Seat Belts switch.

    Regards,



  • Good evening.

    Even when the GPU is activated from everywhere, it stops working after a while.

    Another thing, I find the takeoff not realistic enough, the plane has trouble to take off. With four engines it shouldn't be so difficult.

    You should have added sounds in the cabin.



  • @Mangouste I'm going to take a guess here and say you are trying to fly it like any other airliner? I have no problem getting off the ground at the correct speeds.

    To quote Mike Riley (Concorde instructor),
    "Until the nose is raised and some wind gets under them the wings have no function except to complement the look of the fuselage and fin. This is different from a conventional airliner which lifts some of its weight off its wheels as it picks up speed, and likes to roll sideways if there is a crosswind."
    "It would be nice to be able to fly away at 400kts. At takeoff weight this is the minimum drag speed and therefore below the best climbing speed for miles per gallon. 400 is, however, subsonic VMO and official climbing speed; it gives you 4000fpm. Sadly, the tyres are only good for 250mph and runways are of a limited length so takeoffs are arranged to rotate at 200kts and leave the ground at 220, which happens to be V2. At this speed the drag is high which is why Concorde takeoffs look disappointingly pedestrian from outside."

    There's plenty more info out there should you wish to research it, but key points are rotate to about 13 degrees initially which will set you in a gentle climb and as 250kts is approaching lift the nose to give a pitch angle of roughly 18 degrees which should arrest the acceleration and increase the climb rate.

    Cheers,
    Paul.



  • @Delta558 I know the Concorde very well, I flew with the one from FSL which is the best, under FSX. I now have P3D 4.5.
    And I repeat that the Concorde DC Designs has no power for takeoff. It has no thrust reaction, while the real one has much more power with its four engines.



  • Okay, well I've just compared the take off in the DC Designs Concorde to the following clip:
    https://www.youtube.com/watch?v=1bjzoh3iQJc

    Bear in mind that we have no idea of the AUW in that footage, so I set the sim to fully loaded but with the tail tank at 75% (so just a couple of thousand pounds below MTOW). In the video, throttles forwards to Vr takes 40 seconds. In the sim, 41 seconds. Interestingly, the callout of 100kts occurs almost precisely at the same runway marker point in the vid as it is reached in sim.

    I agree that the FSLabs Concorde was the best we're likely to see. I spent several years with that as my primary 'relaxation flying'! This is not intended to be in competition with it, it is aimed at an entirely different market, has far less people working on it (2, I think?) and a much, much shorter development timescale. Given those points, and the comparison above with the real aircraft, I'm struggling to agree with you and really think it is close enough.

    Cheers,
    Paul.



  • @Delta558

    Well then it's me who has a problem with your plane. Example with the FSL I take off from Nice LFMN runway 22R or 22L. No problem.
    With yours I end up in the water, because the plane refuses to take off because it doesn't have enough speed.

    Then I know that the real Concorde does not take off from Nice. But the one from FSL or Colimata can, but not yours.

    Yet I put myself well at the end of the runway, I accelerate at 80% with the brakes, the nose at 5 degrees, I let go of the brakes, post combustion and I end up in the water 4/5 times.

    I add that I like your Concorde. I find it pretty, with a very good pilot cabin. But I have this problem that doesn't seem coherent to me.

    Thank you for answering.



  • ok I probably had a bug, but it's limited anyway. See my video :

  • @Mangouste At the moment, I have virtually no internet so I'm struggling to even load this page let alone the video! However, I did try a max weight takeoff from Nice and was airborne shortly before the end of the runway. I'm going to take a guess and say that operations from Nice would have been at lighter weights, given that the runway is about 1000m shorter than Heathrow, which in turn is a few hundred metres shorter than Charles de Gaulle.

    Cheers,
    Paul.



  • I think of a bug at the installation. I now have no more problems after another installation.

    Thank you very much for your answers.



  • Glad it's sorted for you.
