Saab 340b. I understand that a number of compressor stalls have occurred on this plane. Is that a concern?

Question

I have been informed that a temperature inversion of 5 to 7 degrees C can contribute to this. Does this mean an aircraft engine of this type can stall more easily than a typical modern car engine?

A compressor stall is when the airfoils on the intake blades of the engine stall aerodynamicly. that is the airfoil stops producing lift (the fan blade), and causes the engine to stop compressing air for the combustion chamber. Its a concern for the pilot not to exceed the opertaing limits of the aircraft's engine, but a not a major concern for passengers as long as the pilots doesnt do anything stupid. ..

Partial answer.

Answer 2

The temperature of the air reduces as you increase in altitude down to about -40 at 36,000 ft. Turboprops don;t usualy operate at this height though. I don't see why 5 to 7 degrees has any effect in particular?

Cars have recipricating engines not jurbine engines.

Answer 3

You are talking about two totally different types of engines there, a jet/turboprop engine vs. a reciprocating... definitely not the same...

The fact is, the SAAB 340B is a very light airplane and has a VERY good safety record... especially after the change to the weight and balance certifications.

The SAAB 340 can very easily, and quite routinely for the pilots, make an emergency landing on one engine...
