At first glance, the Bombardier Dash 8 Q400 and ATR 72 may seem like very similar aircraft. After all, both are small twin turboprops with their wings on top of the fuselage. When you look at the specifics, some key differences emerge.
The ATR is slightly smaller than a Q400, however it is significantly cheaper. As far as performance, the Q400 will happily take those extra 10 passengers an extra couple hundred miles, but it’s going to take a lot more runway to get in the skies and it’s going to drink a lot more fuel. Both aircraft have racked up many orders (around 2000) across their families and remain popular choices for short haul flying.
