What would happen if a jet flew in a layer other than the stratosphere?

The stratosphere is the second layer of Earth's atmosphere, just above the troposphere, and below the mesosphere.


as such you will find that all planes do in fact fly in a layer other than the stratosphere and do so quite well.What would happen if a jet flew in a layer other than the stratosphere?
There would be over 100 alerms gooding off to tell pilot to fly down and if hes deth then you would proble get those little mask breath things that pop down and it would stallWhat would happen if a jet flew in a layer other than the stratosphere?
Servince ceilings are the top alititude an aricraft can fly. The engines is what limits an aircrafts service ceiling. As said before basically you have engine failure. Small aircraft using recipricating engines with regular float cards have lower service ceilings. As you go up in altititude the air thins out. You need specific amount of air to fuel called the air fuel mixure or A/F ratio. So the small float carb engine can only support combustion until it reaches an altitude where the air is thin enough to throw off the a/f ration to where it wont burn. Now add a supercharger or turbo charger and you are getting the thin air pressurized and are able to operate at higher altitudes. In fact many super and turbo chargers boost the pressure to the same as at sea level. Now moving on to Jet engines which can compress a lot more air than reciprocating engines and you have the most ideal engine for high altitude flight. Of course it suffers the same problems once it gets even further up to where the air is very very thin. Eventually it's A/F ratio will no longer support combustion and the engine will fail. Now moving on the rocket engines. These provide all the needs for combustion and can operate in space with zero air.
would stall if jet flies too high due to lack of oxygen and would deprive the engine of oxygen to burn fuel and cut off fuel supply to engine. jet would stall and fall back down to lower altitude.
blow up prob
nothing
