Can't start this thing!



    1. I have been working with this plane for about a month. I will not give up. But: How on earth do you start it? Yes, I've read the manual and have diligently done what it says to do. But it spools up, and then dies. Time and time again.

    2. Somehow, I've saved scenarios with the engine already started. Fine. But once airborne, I find it next to impossible to stabilize the altitude to engage the AP. Not impossible, just "next to."

    3. In any case, once airborne, the plane sometimes just takes off for the heavens, even with AP off, and throttle at ZERO!

    4. Finally (for now), can anyone explain to me the relationship (if any) between the KIAS as indicated by P3D and the speed as indicated in the Vulcan. This is supposed to be a supersonic plane, and yet I get an "Overspeed!" warning at 400 K. Moreover, sometimes at cruising altitude, with AP engaged, the speed just drops off until it stalls and loses control, even at full throttle. Huh?

    Thanks all,

    Mac6737



  • @Mac6737 The Vulcan is not supersonic (Routinely!)



  • @Roebuck

    OK, fair enough. But the Manual says it's max cruising speed is Mach 0.95. So that's getting close.

    1. The engines sounds very much like you haven't got fuel going in - All fuel panel switches on, LP cocks (under the Fire Buttons / RAT handle), HP cocks (throttles all forwards of the gate - right click?) and then throttle position - the throttle lever for the engine you are trying to start needs to be quite a way forwards depending on the type of start you are trying.

    2. and 3) it is twitchy in pitch, but that's speaking reletively for a medium bomber. You should be able to stabilise it quite easily, but you will need to trim forwards from take-off and keep on top of the trim throughout.

    3. Max Mach number is at altitude. There are two constraints, you cannot pass one just because the other exists. From memory, the IAS limit in Air Force service was 350kts. Low level it equates to 0.53M but as you climb through (18,000?)ft you convert to mach readings, maintaining the climb at 0.7M. You will be able to accelerate the aircraft as you level out, but be aware that the max mach number is NOT where you should be flying routinely - at that speed, because of the tuck experienced by the airframe the mach trimmer has balanced things out and you will have very little remaining pitch-up authority. 0.89M is a more usual limit in service, even though the aircraft is physically capable of more.

    (figures above are from memory, manuals not to hand and I'm heading off to work!)

    Hope that helps,
    Paul.

    Paul,

    Thanks. You were right about the fuel panel switches. (It didn't help that the switches are not visible in one of the 2 views of the coaming; the guards are, but not the switches!) After finding the switches, I used the rapid start sequence. ONLY the No. 3 engine started. Pushing the individual engine start buttons had no effect. CTRL + E in this bird has no effect, either.

    In any case, p. 57 of the Manual tells you how to go to the Add-ons menu and select a panel state: "cold & dark" or "Ready for takeoff." So I tried the latter. No luck. As before, it sounds like it's spooling up, but then fades away. I would like to get this thing airborne and worry about a cold start later. What is it about "Ready for Takeoff" that I don't understand?

    BTW, the only way I've ever gotten the engines started is to cheat: select another plane, start the engine and then select the Vulcan. But today, not even that worked.

  • @Mac6737 okay, so just focussing on what you have said in that latest post:

    Fuel should now be available to the engines.
    Have you set the left-side start panel correctly? 3 toggle switches, Ignition ON, start master ON, rapid / normal set to rapid. The air crossfeed indicator should be white.

    The throttles at this point all need to be set to 50% +, make sure they are well forwards but not fully open.

    Then back to the start panel and press the black rapid start button behind the individual engine start buttons.

    As the engines spool up, the dolls eye indicators on the centre front panel should change from white to black to show that fuel pressure is good.

    See how you get on with that, if it comes to it we'll have to sort out a time to run through it step by step from cold and dark to see if we can work out what step you are missing.

    Cheers,
    Paul.



  • @Delta558 Thanks again. The next day, I was able to select "Ready for Takeoff," and discovered that means "Eventually . . . ."
    If you wait a while, all 4 engines spool up. So now at least I can get off the ground.

    I'll try again later to do a cold start.

    BTW, notwithstanding p. 57 of the Manual, saving a flight does NOT save the panel state. Yesterday I saved a flight at 32,000.'
    When I loaded that scenario today, I was at 32,000', but no engines on, and the landing gear extended!
