A340 Take Off?

Featured Replies

Hello,I know how to take off but A340'S are the ones I'm focusing now ater Boeing 747-400. I know you slowly pull the stick at about 140kts but on this A340 I slowly pull the stick on 140kts but it the nose doesn't go up but I kept on pulling up at about 180kts but the nose went up slowly but the aircraft over ran the runway and crashed into the building. By the way I set my flaps to 10. Does anybody know whats going wrong with my takeoff or aircraft?The other thing is that once I took off (this was some lucky day) I went to about 2000ft and engaged the autopilot to 11000ft and 280kts however the aircraft just stalls and falls to the ground. Does anyone know why and how to fly properly with an Airbus A340?Thanks and have a happy new year

What A340 are you referring to, as Airbus uses flap settings of 1,2,3,4?Also, if it is heavy, it needs flaps3, and you will need to use up most of the runway.Once you engage AP, you need to accelerate "slowly" to 250kts below 10,000ft, and make sure not to exceed 1200ft/minute until you reach 250kts, and clean up the flaps.P.S. I am not an expert, and the numbers are not very accurate, especially since I do not know what A340 (payware, freeware) you are talking about. Also, if freeware, what type of panel are you using.Good Luck.

Sorry about that but my Aircraft is an Airbus A340-300 and its a freeware. Are there any other infomations I need to know?

Sounds like you're not setting the correct trim for takeoff. Apply some nose up trim and you should find that the aircraft will rotate at a much slower speed.

Thank you that worked but I'm still stuck on the autopilot part can anybody help?

Not sure. First up, is this by any chance a Project Opensky A340? I've found that a bit quirky, especially on takeoff and climb-out, although I've not had the specific problems you mention and heavies aren't really my thing anyway. In more detail - what happened? Did the aircraft pitch up markedly first? Did it actually reach 280kts or not? Either way, here's a couple of possibilities: - what vertical speed have you set for the climb? As others have said you need to keep this down while building up speed to 250kts. After that 1800 fpm or so should be fine depending on weight. But try a lower rate of climb anyway. - in your realism settings, do you have the ASI set to show true rather than indicated airspeed (which is lower than true airspeed, by a margin which increases with altitude)? 280kts true is a bit on the low side although probably not low enough to cause a stall at 11,000 feet. 280kts indicated would OTOH be about right. If so, change it to show indicated airspeed instead, which is more realistic anyway. Finally (and generally) bear in mind that autopilots and autothrottles just try to do what they're told - they can't defy the laws of physics or turn an airliner into a fighter. So for instance you can't expect an A340 autopilot to climb at 3,000 fpm while maintaining 300 knots IAS. Real-world Airbuses (and other types) have inbuilt protection to stop the pilot setting them in ways that would cause stalls or other catastrophic events. Freeware models generally don't - which means you find out the hard way I guess.

Your best bet is to acquire a flight manuel with the speed/weight schedules.1. To ascertain your correct Vr2. Your correct V2 etc.3. Your correct flap positions.4. Your correct attitude after rotation.5. Your correct noise abatement speed.6. Your correct accelerate and clean up A of A.I'm afraid jets don't handle like cars. You have to always set the correct configuration for speed/weight rate of climb/descent etc.Even the old VC10 which "does" fly like a fighter has to be flown properly with regard to it's weight etc.vololiberista

Sounds like it could be a few things, especially if it isn't a particularly realistic simulation of the real A340 (which is likely if it is a freeware model). some things to check:Not overloaded? i.e. make sure you haven't got full fuel and a full payload, the real A340 is not an especially lightweight airliner, so it would never make it off the deck when overloaded, and a simulated one probably won't either.Trim set? i.e. depending on your payload and fuel on board, you will need to alter the elevator trim, probably to somewhere around four or five.Autothrottle engaged? You can engage the autopilot to track altitude and speed, but you need the autothrottle to be engaged too, and from your description it sounds suspiciously like you set the autopilot to climb at a certain speed, but without engaging the autothrottle to actually make it fly at that speed, resulting in the aircraft trying to climb without sufficient thrust. Most Airbus autothrottles are a bit weird when you are used to a Boeing, they do not physically move the throttle levers as the autotrottle like on a typical Boeing, so you could have the autothrottle not properly engaged on an Airbus and would not necessarily be able to tell that was the case simply by looking at the throttle's position on the pedestal. Modes properly engaged? The autopilot mode control panel on a typical Airbus is rather different from that on a typical Boeing, the switches, dials and displays are not quite so intuitive, and many of them have several modes, which can be confusing. Your best bet to ensure that they are engaged properly is to check on the PFD and MCP annunciators to ensure the autothrottle, climb and altitude settings are actually engaged (check a mamnual to ensure you know what annunciations you are looking for). These choices aren't displayed in the same way as they are on a Boeing's MCP, for example, managed modes controlled by the FMC tend to remove data from the MCP windows and display dashes in the windows instead, in order to indicate you have an FMC-controlled mode selected.There is no truly realistic simulation of an A340 for FS, but you will find the Wilco payware version is pretty close in many respects, so worth having if you desperately want a fairly decent Airbus. How realistic your freeware one gets is debatable, but I should think it is not especially similar to the real thing, nevertheless, here is the real A340's Flight Operations Manual if you are curious about the real aeroplane: http://www.smartcockpit.com/pdf/plane/airbus/A340/systems/0004/Al

Check out my youtube flight sim videos: Here

The real Airbus A340 has a FBW autotrim system whereby the computers keep the aircraft in trim at all times, allowing for the removal of artificial feel systems. However no one in FS right now can accurately simulate this system. (Airsimmer was the closest)Also beware of ice, a few tonnes of it can seriously degrade performance.

Thanks guys the problem was that I had to put the elevator trim up like 1 degrees or sometimes 1.5 degrees. Thanks for help happy new year
