How do I start and take off in the DCS World F-15C?

In DCS World’s F-15C, use the automatic start command for a cold aircraft, or switch on electrical power and start each engine manually. Close the canopy, set take-off flaps, taxi to the runway, apply full military power or afterburner, rotate smoothly at roughly 130–150 knots, then raise the gear once climbing.

The F-15C is a Flaming Cliffs-style aircraft with a non-clickable cockpit. Starting it therefore relies on assigned commands rather than pressing battery, starter or fuel switches with the mouse.

Which F-15C start method should I use?

Use automatic start while learning, and the individual power and engine commands when you want a shorter, more deliberate procedure.

On the standard keyboard profile, automatic start is normally LWin+Home. Common manual bindings are RShift+L for electrical power, RAlt+Home for the left engine and RCtrl+Home for the right engine. Imported profiles and controller software can replace these, so confirm them under the F-15C column in Options > Controls; our summary of the default DCS keyboard and mouse bindings covers the other basic flight commands.

1. Set the throttle to idle. Hold the wheel brakes or make sure the parking brake is set. A throttle axis that is not fully at idle can interfere with starting.
2. Close the canopy. The usual keyboard command is LCtrl+C, although automatic start may handle it as part of the sequence.
3. Start the aircraft. Press LWin+Home and let the automatic sequence finish, or turn on electrical power and start the two engines individually.
4. Wait for stable engines. Do not taxi as soon as the first engine begins turning. Let both settle at idle and check for obvious warning indications.
5. Configure for taxi. Check pitch, roll and rudder movement, set the flaps to the down or take-off position, retract the airbrake and centre excessive trim.

DCS ATC is not required to make the aircraft move, but missions may expect you to obtain permission before starting or taxiing. The procedure for requesting start-up, taxi and take-off clearance through DCS ATC also explains the communications menu and radio-mode differences.

How do I take off in the DCS F-15C?

A successful F-15C take-off depends on a straight acceleration, a gentle rotation and prompt gear and flap retraction after lift-off.

1. Complete the line-up checks. Confirm canopy closed, flaps down, airbrake retracted, gear down and flight controls responding correctly. Use the mission’s specified take-off trim; if none is supplied, avoid large nose-up trim inputs.
2. Taxi under control. Keep the speed low and steer with small rudder inputs. The manoeuvring-range nosewheel-steering command is intended for tight, slow turns and should not be held during the take-off roll.
3. Stabilise the engines. Hold the brakes, advance both throttles together and check that the engines respond evenly. Release the brakes, then select full military power or afterburner.
4. Keep the aircraft straight. Use small rudder corrections. Large inputs produce weaving and can become worse as the nosewheel unloads.
5. Rotate smoothly. For many normal combat loads, begin easing the nose up around 130–150 knots and establish roughly 10 degrees of nose-up attitude. Do not pull sharply or force the aircraft off the runway.
6. Clean up after lift-off. Once the aircraft has a definite positive climb, raise the landing gear. Retract the flaps after gaining safe speed and height, then reduce from afterburner when it is no longer required.

A runway-start mission removes the start-up workload while you learn directional control and rotation. Our guide to finding DCS training lessons and repeatable take-off practice explains the useful training and Instant Action options.

Should I use afterburner for take-off?

Use afterburner for a heavy aircraft, a short runway or a tactical departure; full military power is normally adequate for a lighter aircraft on a long runway.

Afterburner shortens the ground roll but consumes fuel rapidly. If you use it, cancel it once the aircraft is safely climbing unless the mission requires continued maximum performance.

What is the correct F-15C rotation speed?

There is no single correct rotation speed because fuel, weapons, runway conditions and air density change the required take-off performance.

Around 130–150 knots is a practical starting range for many ordinary DCS World mission loads. A heavily loaded aircraft may need more speed and runway. Watch the aircraft’s response: ease the nose up, hold a moderate pitch attitude and allow the main wheels to leave the runway rather than increasing back-pressure abruptly.

Why won’t the F-15C start or take off?

Most failed starts and take-offs come from conflicting control assignments, brakes remaining applied or trying to rotate before the aircraft has enough speed.

• Automatic start does nothing: verify that Start Procedure is assigned under the F-15C controls, not another aircraft’s column. Also check that Windows or controller software is not intercepting the command.
• One or both engines will not start: move the throttle fully to idle, switch on electrical power and check for duplicated throttle assignments across the joystick, throttle and game-controller columns.
• The aircraft will not move: release the parking brake, remove wheel chocks if the mission uses them and inspect toe-brake axes. DCS often requires pedal brake axes to be inverted.
• The aircraft veers across the runway: check rudder and brake axes for noise or reversed input. Use small corrections and avoid the high-angle nosewheel-steering mode during the take-off roll.
• The nose will not rise: confirm that the pitch axis moves through its full range, the aircraft is fast enough and no second controller is commanding forward stick. Excess fuel and weapons also increase the required speed.
• The aircraft sinks after lift-off: avoid retracting the flaps the instant the wheels leave the runway. Establish a positive climb, accelerate and then clean up the aircraft.
