Start the Quest Kodiak cold and dark with the correct PT6 lever setup, starter sequence, instrument checks and fixes for failed starts.
To start the Quest Kodiak from cold and dark, set the parking brake, establish battery power, keep the avionics off, open the fuel supply, engage the starter, and introduce fuel with the condition lever once Ng is sufficient. Monitor ITT and oil pressure, stabilise at low idle, then bring the generator and avionics online.
This is the common PT6 start logic used across Microsoft Flight Simulator, X-Plane, FSX and Prepar3D. Exact switch names, starter behaviour and operating limits depend on the Kodiak add-on, so use its checklist for the specified Ng, ITT and starter-duty limits.
How should the Kodiak's levers be set before starting?
The normal starting configuration is power lever at idle, propeller lever fully forward and condition lever at fuel cut-off. Select an available fuel tank or open the fuel shut-off control, depending on how the particular Kodiak models its fuel system.
Check physical throttle assignments as well as the cockpit levers. A mixture axis mapped to the condition lever can quietly return it to cut-off, which is one of the most common reasons a simulated PT6 lights briefly and then stops.
Quest Kodiak cold-and-dark start procedure
- Secure the aircraft. Set the parking brake or use wheel chocks. Confirm that the throttle is at idle and that there is enough fuel aboard.
- Configure the engine controls. Place the propeller lever fully forward and the condition lever at cut-off. Make sure the fuel selector or shut-off valve is in the operating position.
- Establish electrical power. Switch on the battery and the appropriate anti-collision beacon. Leave the avionics master off, but confirm that the engine instruments needed for the start are powered.
- Prepare the fuel and ignition systems. Set the auxiliary or boost pump and ignition controls as required by the add-on's checklist. Some Kodiak models combine ignition with the starter logic.
- Engage the starter. Watch
Ng, the gas-generator speed, and confirm that it rises normally. Do not introduce fuel if the compressor is not accelerating. - Introduce fuel at the specified Ng. Move the condition lever from cut-off to low idle only after reaching the checklist's minimum starting speed. Look immediately for an ITT rise, continued Ng acceleration and oil pressure.
- Monitor the start. Keep the power lever at idle. Abort if ITT exceeds its limit, oil pressure does not appear, no light-off occurs, or Ng stops accelerating below a stable idle.
- Disengage the starter. Some add-ons do this automatically; others require the starter switch to be released or switched off at the specified Ng. Do not leave it engaged after the engine is self-sustaining.
- Complete the electrical setup. Once the engine has stabilised, switch on the generator and any standby generating system required by the model. Check bus voltage and generator load before switching on the avionics.
- Finish the post-start checks. Set the fuel pump, lights, inertial separator and environmental controls for the conditions. Allow the avionics to initialise before programming the route or moving the aircraft.

Why will the Quest Kodiak not start?
A Kodiak that cranks but does not run usually has no fuel introduction, insufficient starter speed or a conflicting hardware assignment. The engine indications tell you which part of the sequence failed.
| Symptom | Likely cause | What to check |
|---|---|---|
| No Ng movement | No starter power | Battery voltage, external power, starter switch, circuit failures and duplicate control bindings |
| Ng rises but ITT does not | No light-off | Condition lever, fuel selector or shut-off, fuel quantity, boost pump and ignition |
| ITT rises, then the engine stops | Fuel is being cut off again | Condition-lever position, mixture-axis assignment and noisy throttle hardware |
| Ng stops below idle | Hung start | Battery condition, starter state, fuel flow and add-on failures |
| ITT approaches or crosses the red limit | Hot start | Return the condition lever to cut-off and follow the model's abort procedure |
| Displays remain dark after starting | Electrical setup is incomplete | Generator, avionics master, bus switches and simulated circuit breakers |
After an aborted start, do not keep adding fuel or immediately repeat the attempt. Return the condition lever to cut-off, clear or cool the engine only as directed by the aircraft checklist, and respect the modelled starter duty cycle.
Does the procedure change between simulators?
The underlying PT6 sequence remains the same, but system depth and switch automation vary considerably between Kodiak add-ons.
- Microsoft Flight Simulator: Assistance options and automated checklists may move controls for you. Disable assisted engine starting when learning the manual sequence.
- X-Plane with REP: REP can model maintenance state, battery condition and start damage beyond the base aircraft. Use the REP-specific X-Plane 12 starting sequence rather than treating it like the standard model.
- FSX or Prepar3D: Older Kodiak packages vary in systems depth. The FSX Kodiak package with supplied checklist and reference files is a useful aircraft-specific reference where applicable.
Should the avionics be on during the start?
The avionics master should normally remain off while the starter is drawing heavily from the electrical system. Engine instruments required to monitor Ng, ITT and oil pressure must still be powered; after the engine stabilises and the generator is online, switch on the avionics and verify that the displays initialise normally.
If a one-key automatic start works but the manual procedure does not, the aircraft installation is probably sound. Compare the automatic control movements with your manual sequence, then check fuel controls, starter disengagement and hardware bindings rather than reinstalling the add-on immediately.
