Six years flying the RJ and in general it was a very nice aeroplane to fly.
A smooth ride and responsive to the controls and a flattering undercarriage.
Airstairs were a nice feature.
It could go down very quickly when it had to. On the other side, it did run out of puff in the climb.
What I don’t miss is the air system. Lots of switch changes after take off and before landing. The air conditioning was poor. After a turnaround in Spain in the summer months it would be about 40 minutes after take off before the temperature became bearable. In the winter if the aircraft had been de-iced before you arrived then you could use the APU to power the packs until after landing so the aircraft would be very cold till some time after take off.
