I flew the more "modern" Avro RJ100 for 2 years - what a lovely aeroplane to pole....Yes, only did M0.70, but it was comfortable to spend 3 hour sectors in. Loads of head and legroom.
Four engines for short airfields - that is the WHOLE point of the 146. Lose an engine and it still goes up at a decent rate. Only decent size jet into places like London City. I'm sorry but you can't call the Embraer Barbie things real size jets, or the canadian thingy.
