SOUNDS The C-17 Globemaster III features the amazing and unique DreamEngine sound plugin from DreamFoil Creations. This allows a much greater control over sounds in X-Plane. It really brings the C-17 to life, from the deafening roar of the engines at the back to the shrill scream of the fans at the front, you’ll feel like you’re standing next to the real thing as it thunders past. With 3D positional sound technology, the pitch, tone and type of sound changes as you move around the aircraft, just like the real thing, and with layered sound it allows a smooth transition between multiple sound samples for a better experience.

SYSYEM SETTINGS The C-17 is a large aircraft, texture-rich and featuring many 3D objects all working at the same time. Like many of the other high quality pay-ware airliners it will place demands on your system and it may struggle at higher settings on old hardware. However if you can run some of the other high performance aircraft available at present, you shouldn’t have any problems with the C-17. The recommended field of view is 80-90 degrees. Recommended system requirements: X-Plane 9.70+ or X-Plane 10.10 Windows XP or later Mac OSX 10.4+ Linux IMPORTANT: The aircraft file (C-17_Globemaster_III.acf) is by default for XPlane 10. X-Plane 9 requires a slightly different version which you’ll find in the folder ‘X-Plane 9 Aircraft file’ together with a read-me file. All other texture and object files are the same.

6) Standby Engine Display (SED). This unit is a digital display of actual engine N2/EPR, EGT, N1, EPR rating, and mode selected. N2 and EPR cannot be viewed at the same time, so a mode switching knob (lower left side) selects OFF/N2/EPR. In EPR mode, several more functions become available. The normal blue EPR rating chevrons on the engine display will change to a solid blue horizontal line in this mode and the five buttons on the right of the SED unit become active, as does the rotary knob on the upper left side. The default EPR (Engine Pressure Ratio) rating is provided by the MAN button, this allows the value to be manually set using the rotary knob, top left Virtavia Pty Ltd C-17A Globemaster III Manual Version 1.0 for X-Plane 9.70 & 10.10


on the unit. The other four buttons provide presets for various EPR ratings (thrust levels). Use caution when experimenting with these as they will adjust engine thrust and this is unwise when on the ground or at low level. From top to bottom, the presets are as follows : Maximum, Intermediate, Maximum Continuous Thrust, Derated Thrust and Manual Control. 7) Flaps Gauge. The Flap Position indicator dial shows flap positions from fully retracted (0°) to fully extended (40.5°). It is graduated in 4° tick marks with labels every 8°. 8) Speed-brake Position Indicator. Shows the position of the spoilerons on the upper surfaces of the wings. Speed-brakes can be activated with keys ‘3’ and ‘4’. 9) Landing Gear Lever.

Set parking brake (center console, left side). Check throttles are at IDLE. Check all switches are OFF including APU. Turn on the Master Battery switch on the overhead electrical panel. Turn on the Master Avionics switch on the overhead electrical panel. Check WACAP on overhead for messages. Check Fuel Quantity is sufficient. Request clearance to start engines. Set an MFD to display ENG 2. Turn on NAV lights (overhead panel). Turn on ANTI-COLLISION lights (overhead panel). Turn on ENGINE IGNITION (overhead panel). Turn on IGN Igniter switches. Press and hold APU Starter switch to 'start'. Wait until 100% RPM reached and set to 'run' position (overhead panel). Turn Engine 1 Shutoff switch to ON (vertical position) (overhead panel). Switch on Fuel Pump 1 (overhead panel). Pull down ENG1 Starter switch (overhead panel). Hold until EGT rises and N2 reaches 25-30%, typically 12-15 seconds, then release. Check ENG1 RPM stabilized (MFD). Turn on Generator 1 (overhead panel). Turn off APU (overhead panel). Repeat steps 14-18 for remaining engines. Turn on Engine Bleed Air (overhead panel).

Avionics: 1. Set HUD to AUTO. 2. Turn on Mission Computers as required. 3. Set CNC NAV/COM frequencies as required. 4. Set AFCS as required. 5. Set STBY ENG display as required. 6. Load FMS flight plan as required 7. Set ALT to first clearance. Anti-Ice: 1. Turn on Pitot Heaters (overhead panel). 2. If conditions dictate, turn on Wing and ENG Anti-Ice (overhead panel). Before Taxi: 1. Check all exits and rear ramp closed and secured. 2. Taxi lights ON.



Taxi: 1. Prior to taxi check flight control surfaces by moving joystick and rudder pedals and verifying control surface movements on the CFG (Configuration) MFD on the main panel. 2. The C-17 will require a different amount of thrust to break away depending on weight. It is not unusual at high gross weights to use up to 70% N1 to start rolling. 3. Use the lowest amount of thrust necessary to start rolling. Using excessive amounts of thrust will cause you to accelerate faster than intended. Remember, engines are still producing thrust as they spool back down to idle. 4. Once you attain 12-15kts of taxi speed slowly reduce power. The aircraft will taxi at just above idle thrust, but may require slightly more at high gross weights. 5. Use maximum nose wheel steering deflection whenever possible. The use of differential braking is discouraged due to heat build-up in the brakes. Before Takeoff: 1. Check Brakes, Steering and Control Stick free movement. 2. Check Flight Instruments, Engine RPM, EGT levels normal. 3. Set Take-off flaps and slats as required. 4. Apply nose-up trim as necessary, either using the main panel Trim gauge or the centre console levers. 5. Taxi lights OFF, Landing lights ON. Takeoff Procedure: 1.

Hold brakes and slowly increase power to approximately 80% N1. When engine readings appear stable, release brakes and increase power to maximum. 2. Accelerate to rotation speed and slowly pull back on the stick to attain a 2.5°/sec pitch rate to 10° and hold. Use the following table to for Vrot rotation speeds (extrapolate for weights not listed): 1. 300,000 lbs = 118 KIAS 1. 320,000 lbs = 120 KIAS 1. 340,000 lbs = 122 KIAS 1. 360,000 lbs = 124 KIAS 1. 380,000 lbs = 126 KIAS 1. 400,000 lbs = 128 KIAS 1. 420,000 lbs = 130 KIAS 1. 440,000 lbs = 132 KIAS 1. 460,000 lbs = 134 KIAS 1. 480,000 lbs = 136 KIAS 1. 500,000 lbs = 138 KIAS 1. 520,000 lbs = 140 KIAS 1. 540,000 lbs = 142 KIAS 1. 560,000 lbs = 144 KIAS 1. 580,000 lbs = 146 KIAS 1. 600,000 lbs = 148 KIAS At Vrot apply back stick pressure and maintain climb angle of at least 12° and not more than 15°. Virtavia Pty Ltd C-17A Globemaster III Manual Version 1.0 for X-Plane 9.70 & 10.10


As soon as positive climb rate is verified, raise landing gear. Adjust trim as necessary after gear has retracted to maintain 12°-15° hands-free. Retract trailing edge flaps. Once trailing edge flaps are fully retracted, select desired Climb Thrust (MCT) or (INT) on the SED (main panel). Retract leading edge slats.
