ATR incorrect data

Hi all,

 

Further to my recent posts about incorrect data, I believe there may also be some errors with the ATR -42 and -72 family of turboprops. In particular, the range of the -600 series is significantly overstated.

 

There are also a few types missing (42-320 and 72-210), which I have requested in the “aircraft requests” thread.

 

Observations based on this brochure from the ATR website: http://www.atraircra...ptembre2014.pdf

 

I couldn’t find historical data for the ATR-42-200, but it’s possible these numbers need updating as well.

 

ATR-42-300

ATR Min Runway = 3,822 ft

 

*AE Ave. Speed = 310 mph

*ATR Max Speed = 345 mph (300 ktas)

 

AE Max Pax = 50

ATR “Standard Config” Pax = 48

 

 

ATR-72-200

 

AE Max Payload Range = 660 mi

ATR Max Payload Range = 1,004 mi

 

AE Fuel Flow = 2,246 (units??)

ATR-72-500

 

AE Max Payload Range = 666 mi

ATR Max Payload Range = 903 mi

 

AE Fuel Flow = 2,387 (units??) – PW127

ATR Fuel Flow = 1,680 lb/hr – PW127F/M

 

AE Min Runway = 3,410 ft

ATR Min Runway = 4,016 ft

 

*AE Ave. Speed = 318 mph

*ATR Max Speed = 317 mph (275 ktas)

 

AE Max Pax = 74

ATR “Standard Config” Pax = 68

 

 

ATR-72-600

 

AE Max Payload Range = 1,528 mi

ATR Max Payload Range = 949 mi

 

AE Fuel Flow = 2,443 (units??)

ATR Fuel Flow =  lb/hr

 

AE Min Runway = 4,560 ft

ATR Min Runway = 4,373 ft

 

*AE Ave. Speed = 305 mph

*ATR Max Speed = 317 mph (275 ktas)

 

AE Max Pax = 78

ATR “Standard Config” Pax = 70

 

* I wasn’t sure what “average speed” refers to, and I couldn’t find any reference to “average speed” in the documentation, so I have included the stated maximum speed for reference.​
