Original Note:
White smoke from the aircraft’s APU during startup can be due to unburnt fuel vapor. When the engine is shut down, fuel left in the manifolds can coke up in the burners. When you try to start again, the fuel spray might miss the ignitor leading to the emission of white smoke. https://youtu.be/Aaejx0VRoY0?si=tyH46BShu8ypderg
