OO-VEG, you´re right. The Avro RJX project was cancelled, with the term "RJ" I refered to Regional Jets such as the CRJ700/900, Embraer 170,175,190,195 and the 728/928JET, not to the ARJX. The onlyairlines having placed orders for the ARJX were British European and Druk Air. The latter is known for looking at the A319 and large RJs to fulfill its future requirements, BE is said to be interested in additional Dash 8-Q400 and wants to make a new RJ decision in late 2002.
