There is no performance advantage with the reversers if memory is correct.
Correct, and let's not forget that Crossair and BACX's E145 fleet had no TRs either. Not sure about City Airlines and BMI Regional. Some of the Crossair 145s ended up at Trans States.
Now here's something I had forgotten about the 145's system (it was mentioned on another bb): If you have weight on wheels but no wheel speed (due to hydroplanning) then the logic dictates that a wow fault is present and
brakes, TRs and spoilers are locked out, because the logic assumes the aircraft is flying. TRs wouldn't have mattered anyway, it seems.
(Time to hit the systems book again -
)
The company TSA which owns the aircraft had the reverses removed for cost savings.
Not quite. They simply ordered them without TRs. CHQ has some as well, I was told.
