concorde can't reach high altitude

Recommended Posts

hii try to fly the concorde. but i can't climb to high flightlevels. at FL 400 i get a stall with full power. fpm 1'000.does anybody know how to fly concorde?

You need to keep your speed up. You should reach Mach 1 at around FL290. Put up your visor, engage reheat (Shift+F4) for extra engine power, get up to Mach 1.7 (while being careful not to overspeed) and then turn the reheat off - then continue accelerating to Mach 2. You should reach Mach 2 at around FL490. 1,000 fpm should be absolutely no problem.Kitty MercuryCathay Pacific Virtual Pilot (CX252)

First get the set of realistic flight dynamics released by Paul Varn from www.flightsim.com. A new "REALITY UPDATE" will be released shortly by Paul, which with help from myself, many Concorde enthusiasts, and a handful of Concorde pilots, will prove to be the most realistic set of flight dynamics ever released for this aircraft!How to fly the Cruise Climb:This stage of flight is flown using the two autopilot modes, MAX CLIMB and MAX CRUISE - however these are not present on the default FS2000 Concorde. Once the reheats are engaged (in pairs), the nose is raised to 7*, speed is around 400KIAS VMO between FL280 and FL320. Passing FL320-500, the speed increases from 400 KIAS up to 530KIAS with a pitch attitude of about 5*. Passing M1.70 (around FL430) the reheats are switched off, and the aircraft continues to accelerate on full dry power. On passing flight level 500, Concorde begins its cruise climb. This puts the aircraft into a slow climb of about 50 feet per minute (fpm). Also passing FL500 (a little after) the Cruise engine rating setting is applied. Cruise Climb is the most efficient way for the aircraft to fly at these altitudes. Using a fixed power setting, the fuel is burnt off, which decreases the weight of the aircraft, which allows it to climb higher. A bit like the same way any other commercial jet liner would, they 'step climb'. Like the Concorde, as they burn off fuel, they will 'step up' to the next flight level. Concorde doesn't need to perform these steps, as it is the only aircraft operating on the airway in only one direction. E.g. All the Westbound flights will fly on the SM Track, and all the eastbound flights will fly the SN. In Concorde, this 'Step Climb' is referred to as 'Cruise Climb', which was used by other aircraft in the early days before subsonic airspace became more populated. So depending on the temperature, and the amount of fuel burnt off, the aircraft climbs at a slow rate (+/- 50fpm), starting off at around FL490-520 and will end up at the end of the cruise somewhere around FL570-600. The aircraft never actually cruises at FL600. That's about all there is to it! You have to watch the TOT. Max on the nose is 127*C. Very rarely do you reach this temp, however a few weeks ago before the UK had the heavy winds, there was a high temp area just South of Ireland (-48), and many inbound flights had to slow up passing 20West - flying at M1.98 just under Max TOT. Also the London - Barbados run requires low air temps, and is quite tight on fuel to get down there. It is vital that the CG position is correct - and on occasions the rear tank (11) becomes full. This results in not being able to pump any additional fuel aft. When this happens, you start to burn additional fuel, and on occasions - it's been touch and go whether the aircraft can make its destination or not! So you can see that the temperature plays a large part in how the aircraft is flown at these altitudes! Hope this helps.Andrewhttp://ftp.avsim.com/dcforum/User_files/3dc0629457f3286f.jpg

Keep in mind that you need to keep a close look at fuel flow between fore/aft res. if you want to reach mach 2 !Cheers,Smalco

Do a search for mvconcrd.zip at Flightsim.com. It has a very good and detailed explanation on how to fly the Concorde. Also, look for mvconwld.zip for a round the world tour. Lots of Fun!Be well,Marcelo.

And just a reminder -- As alluded to in Andrew's detailed description, insure that your sim is set to "Display Indicated Air Speed" not true airspeed. I don't recall the menu where you check and/or set that option. Hmmmmm? R-
