"slowing to turbo prop speeds"
What you mean keeping 265kts to 4 miles then???
Honestly some people get so up about this, but having flown both there is nothing more frustrating than being in a turbo prop and having to SLOW DOWN to jet speeds on the approach because of the 737 ahead!! ( I now fly 737's).
The capabilities of the Turbo Prop in the final maneuvering area are far greater than that of a jet, plus the jet doesnt need the spacing behind the turbo prop that the opposite would require!
Now if we were to discuss something like a 30 something seater turbo prop on a main stand at EDI while I park at A12 with my 149 seats we could mybe get a more reasoned disscussion going!!!!!
