Analyzing COMAC ARJ-21 operating number is possible from the latest Skailark data, which provides insight not only into the COMAC C919 but also the ARJ21. Â We have been following the ARJ21 program for some time, and the program had a long gestation period. Like all Chinese commercial aviation operations, getting a handle on things is not easy.

Co-Founder AirInsight. My previous life includes stints at Shell South Africa, CIC Research, and PA Consulting. Got bitten by the aviation bug and ended up an Avgeek. Then the data bug got me, making me a curious Avgeek seeking data-driven logic. Also, I appreciate conversations with smart people from whom I learn so much. Summary: I am very fortunate to work with and converse with great people.
