I was wandering if the height of the new engines on the max 8 could coarse the jet fuel to self ignite. Jet fuel burns at 38 degree celsius and self ignite at 210 degree celsius. The engines are to big for the old 737 model so the engines are lifted so high up in front of the wing that the outlet from the engines run over the back side of the wings , also why the plane needs MACS, and can get up to 600 degree celsius, is this safe ?.
Even the Aluminium construction can this handle the heat in the long run ?.
