Before we get into comparisons, we should note that we’ll be looking at the ATR 42 and 72, as well as the Bombardier Dash 8 and its variants. We do need to note that the Dash 8 program had recently changed hands in 2019, with Bombardier selling the program to the Longview Aircraft Company of Canada. The manufacturer itself has actually been rebranded as De Havilland Aircraft Of Canada and has revived the Dash 8 name, where Bombardier had once called it merely the Q400.
We mention Bombardier in the title, as well as within this article, as it has been the dominant manufacturer of the Dash 8 recent decades, with De Havilland Aircraft Of Canada only taking over recently.
With that out of the way, let’s look at the battle of these two turboprop programs.
Dash 8 program beginnings
The Dash 8 was initially designed by De Havilland Canada, a company founded in 1928 by the British de Havilland Aircraft Company. The Canadian Government subsequently acquired de Havilland Canada in 1974.
However, it wouldn’t be until the mid-80s that the first Dash 8 would take form. According to BAE Systems, the very first prototype DHC 8-100 (C-GDNK) flew for the first time on 20th June 1983, entering service in October 1984.
The Canadian Government would then sell the Dash 8 program to Boeing in 1986, who would later go on to sell it to Bombardier in 1992. From 1992 to 2019, the Dash 8 program would remain with Bombardier. The most recent variants of the Dash 8 produced by Bombardier would be called the Q-Series and exclude the ‘Dash 8’ name. They would be branded as the Bombardier Q100 through to Q400.
ATR program beginnings
The manufacturer’s name is an acronym that stands for Aerei da Trasporto Regionale in Italian or Avions de transport régional in French. In English, this translates to Regional Transport Aircraft.
Established in November 1981, ATR began as a joint venture between Airbus co-founder Aerospatiale and Italian company Aeritalia. Both founding companies have changed shape over the years, and ATR is now a joint partnership between Airbus and Leonardo, with the company’s headquarters in Toulouse, France.
Although the company was established in 1981, it took some time to develop its first product: The ATR 42. This new aircraft would make its first flight in Toulouse, France, in 1984. It wasn’t until 1986 that ATR would go on to launch a larger version named the ATR 72.
With the Dash 8 program morphing several times, comparing the two families of aircraft is not as straight forward. These days, the Dash 8 program really only consists of a single aircraft, while ATR still produces two. However, for the sake of comparison, let’s include the most recent (yet discontinued) version of the Bombardier Q300.
Aircraft comparison: Q300 vs. ATR42-600
Capacity: The Bombardier Q300 best competes with the ATR42. The former can accommodate between 50 and 56 passengers while the latter can seat up to 50 passengers.
Range: The ATR42-600 can fly a full load of passengers 1,326km while the Q300 has a range of 1,558km.
Take-off distance: The Q300 has a take-off distance of 1,178m while the ATR42-600 can take off with just 1,036m of runway.
Efficiency: Aircraftcompare.com lists the ATR42-600’s fuel economy at 0.758 kilometers per liter while the Q300 covers 0.499 kilometers per liter.
Aircraft comparison: Q400 vs. ATR72-600
The Bombardier Q400 most closely competes with the ATR72. However, the Q400 is a little over five meters longer than its competitor. This will, of course, be a slightly skewed comparison.
Capacity: The ATR72-600 can accommodate as many as 78 passengers. The Q400 can actually seat up to 90.
Range: The ATR72-600 can fly a full load of passengers 1,528km while the Q400 has a range of 2,040km.
Take-off distance: The Q400 has a take-off distance of roughly 1,400m, while the ATR72-600 can take off with just 1,175m of runway.
Efficiency: Aircraftcompare.com lists the ATR72-600’s fuel economy at 0.333 kilometers per liter, while the Q400 covers 0.391 kilometers per liter.
Aircraft orders: The real test of popularity
According to ATR’s website, the company has sold nearly 1,700 aircraft and has over 200 operators in more than 100 countries. Unfortunately, the equivalent statistics aren’t available for Bombardier and the Dash 8 program.
A March 2019 Bombardier report stated that the Q300 and Q400 collectively had racked up 912 orders. After the report and subsequent sale of the program, however, De Havilland Canada would go on to secure several more Q400 orders, including 20 from Palma Holding along with several single-digit orders. If we include the Q100 (299 orders) and Q200 (105 orders), as well as pre-Bombardier orders, the total gets relatively close to ATR.
How do the two companies compare?
The two competitors have had very different histories. ATR seems to be the calm and steady manufacturer, which has slowly developed its two aircraft lines, and made improvements over the years.
The Dash 8 program, on the other hand, appears chaotic and turbulent in comparison – passing from owner to owner throughout its history, being rebranded several times. This has also made our comparison article difficult, as data isn’t as consistent.
The program went from having four variants to just one and has recently been sold off by Bombardier. The latest Dash 8-400 offers more capacity and range than anything ATR can provide and thus has an advantage in that respect. However, as the only variant still in production, airlines have less flexibility for smaller operations.
Hopefully, the Dash 8 program will have a reliable and stable new home at De Havilland Canada that will allow it to remain in competition with ATR in the decades to come.
