Here is our April flight test update for the three programs among the Western OEMs. Note the hours shown are best estimates and come from third parties who attempting to track the programs.
The additional aircraft is helping to build hours. However hours were impacted by FTV2 being in the Florida-based McKinley Climatic Laboratory and not accumulating any hours while doing so. FTV3 flight time is based on an average of 2h per flight (8 flights for April) due to no radar data available on flightradar24 or FlightAware; which means the hours could be understated.
The two major OEMs continue to execute their programs well and Bombardier appears to be doing better but still looks slow. Bombardier has said the winter impacted their test program and we wait to see a program acceleration now that the worst weather is over. They are supposed to add another test vehicle which should help.
In summary, the tables show how the programs are faring. Bombardier clearly needs to accelerate their program hours. Bombardier has averaged 27 flight test hours per month compared to 152.8 at Boeing and 137.2 at Airbus.
