Which two things are needed in the combustor during the start cycle?

Explanation:
During the start cycle, combustion needs two things: an ignition source and a combustible mixture. The spark provides the energy to ignite, while the fuel-air mixture supplies the fuel in the right proportions with oxygen to burn. A spark without fuel won’t produce a flame, and a fuel-air mixture without an ignition source won’t ignite reliably in the combustor. Air alone isn’t fuel, so it can’t sustain combustion. So the combination of a spark and a fuel-air mixture is required to start the combustor.
