Remove Autothrottle on the Dash 8 Q400

I was recently browsing some images of the autopilot panel on a Dash 8 Q400 when I made an observation:

There is no autothrottle control included on the panel! This prompted me to do further research, and I conclude that, as a factory new plane, the Q400 is not autothrottle equipped.



The Q400’s engines are Pratt & Whitney Canada PW150As, the latest in the well-established PW100 series, rated at 3,420kW (4,580shp) each for normal take-off conditions, with an emergency rating of 3,780kW if an engine failed during take-off. ¶ As well as FADEC (which does not include auto-throttle), the PW150A has an engine monitoring system (for maintenance purposes) and electric starter motors.

To keep the Q400 as accurate to real world operation in Infinite Flight, I propose that the feature is removed. Although it is nice and reduces workload, it isn’t realistic. While there is always the “you don’t have to use it” counter-argument (which is valid), I feel FDS should reconsider this currently implemented feature.

Thanks for reading. Please share your opinions on this feature request.

I think this could be used in a rework of the Dash 8 Q-400…

A rework is not needed in my opinion. This is about the only thing I’ve found in error with the Q400. Besides, it was only added a few years ago.


Ok you’ve got a point. I just think it would be odd to just have 1 change…but hey, anything could happen!

Ksisky, you bring up a good point. I feel that it is important to mention that all turboprops need their autothrottle removed wink turboprop change wink but good catch! Definitely deserves my vote!

Its not just the Q400 that have incorrect autothrottle, the Cessna 172 and 208 aren’t supposed to have autothrottle as well as the Cirrus SR-22.

I see your point. However I think the devs might have done this on purpose. Yeah removing it would be realistic but having to balance the throttle during the phases of flight is a bit of a pain.

We could just pretend its the first officer/copilot managing your speed while you fly the plane.

I considered extending this request to other planes with autothrottle in IF, but as those models are not relitvly new, I decided against it, as it would likely be included in a rework.

I wouldn’t mind controlling the throttle manually on the dash 8.
