The E-170/5 is the best-selling Embraer aircraft. Based on ch-Aviation fleet data, 773 of these aircraft are in active status as of today. But this number is nuanced. Look at this chart.

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.
