Enhancements since 2019.1 include a developer preview of the upcoming Compositor graphical rendering framework as a separate pre-built binary, better aircraft carrier support, improvements to both the JSBSim and YASim flight dynamics models, better view options, more efficient and better looking OpenStreetMap buildings and translation of the UI into Polish. This new version contains many exciting new features, enhancements and bugfixes. The FlightGear development team is delighted to announce the v2020.1 release of FlightGear, the free, open-source flight simulator. Several ground bombing scenarios suitable for the A-10, involving moving and static tank formations, explodable M1 Abrams tanks, etc.Please help us translate in other languages!.You can also choose to fly without the AIM-9s and the ECM pod, press Tab or Ctrl-I on the keyboard to display the config menu. (In Flightgear, the key ',' is usaly used for left brake, in the A-10 a nasal script intercepts the binding for weapons release, this is not a definitive solution). This sound is audible only when an AIM-9 is available, selected and searching. Now select Pylon #11, you should ear the seeker sound. Now a big circle appears on the HUD symbology, that the searching aera of the AIM-9. Press key 'e' on the keyboard to fire the gun.įor AIM-9, turn ( C) the AIM-9 Mode Knob to SEL (click on the right side of the knob). You should have on the left side of the main panel a red light indicating 'Gun Ready'. There is actually 2 AIM-9, the GAU9 gatling gun, and MK85 250 pound bombs.įirst of all push up the Master Switch to ARM ( B).įor the gun, push up the Gun Rate Switch to HI (right of the rounds counter). The gun's rounds counter ( A) should be lighted in blue and the HUD should be active. To avoid these problems, if you choose to equip the plane with full armament you may wish to fill the tanks only half full or so-the plane becomes much easier to fly and half fuel is still enough for a reasonably long flight.īe sure to have energy before trying to use the armament panel. Symptoms you would notice are difficult to take off, difficulty gaining altitude, difficult to manoeuvre without triggering stall warnings or actual stalls. At this weight the plane is quite difficult to fly. With fully loaded fuel tanks and a full load of armament, the A-10 is heavy-about 50,000 pounds. The cycling is repeated until fuel is depleted from the external wing tanks first, and external fuselage tank secondly.įor negative G flight, collector tanks will supply the engine with sufficient fuel for 10 seconds operation at MAX power. Main tanks can be topped when the fuel level is below 3034 lbs. Wing tanks can be topped when the fuel level is below 1590 lbs. In this case, opening the valve "tank gate" create a link between the two main tanks.įuel from the external tanks is transfered to the wing or main tanks by pressure from the bleed air system. Unequal fuel level between left (aft) main and right (forward) main tank (imbalance superior 750 lbs) will cause a longitudinal CG shift that may exceed allowable limits. In case of a main tank boost pump failure, the affected engine will suction-feed from the affected tank for all power setting up to an altitude of nearly 10,000 feet. Check valves prevent reverse fuel flow from the main tanks to the wing tanks. In case of a wing tank boost pump failure, the wing tank fuel will gravity feed its respective main tank if the main tank fuel level is below 600 lbs. The main boost pumps then supply the respective engines with the remainder fuel in main tanks. The wing boost pumps ( G switch) supply the respective engines until the wing tanks are empty, then the wing boost pumps automatically shut off. The two feed lines can be interconnected by opening the cross feed valve ( E switch). The right wing and right main tanks feed the right engine. Normally the left wing and left main tanks feed the left engine and the APU. (This could change with future development of engines failures.)įlightGear A-10 starts with all internal tanks full.Ģ wing tanks (left and right), 2 fuselage tanks: left main (aft) linked to left system and right main (forward) linked to right system, up to 3 external tanks (2 wings and 1 fuselage). Now the complete electrical circuit is powered and you can stop the APU to save some fuel. Wait for the starting cycle light to turn off, turn on the corresponding generator and repeat with the second engine. Just click on one of the throttle rails (Ctrl-c to see them), the throttle will move from stop to idle and the engine start. Now that we have minimum electrical power and bleed air supplied by the APU, starting the engines is straight forward.
