Autopilot Throttle?

[TurboKen 221]

OK whats the trick?

I can turn on autopilot set a heading and the plane adjusts to my heading. I set an altitude and it stays or goes where I select. But as soon as I set my speed it does not care, it will not adjust the throttle at all? Sometimes it will actually try to hit the speed I select by putting the plane in a dive and disregard the altitude hold. I have nearly the same autopilot in the TBM and it works perfectly so it seems like a bug, anyone get the Phenom to work correctly?

There's no 'trick'. Like most other Bizjets the Phenom isn't autothrottle equipped. Neither is the TBM.

Well that would explain why I cant get it to work...  

Also, you are right on the TBM, I was thinking of another plane.

Did you modify the auto-throttle parameters in the aircraft.cfg?

These should work:
autothrottle_available=    1
autothrottle_arming_required= 0
autothrottle_max_rpm =   98
autothrottle_takeoff_ga= 0

It works in my Phenoms.

Question before I mod my Phenoms. are you using the FLC knob (if so does that elim the FLC) or something else for the autothrottle?

Hi Folks.

Here's what I do and it works for me. I am not a RW pilot but I find that trial and error in the sim is the best way to find out the little foibles of indiviual aircraft in the sim.

The weight of the aircraft determines the V speeds, I select an airspeed for the initial climb out and then after gear up and flaps inboard I set the power to climb and check the indicated airspeed. As it approaches the selected airspeed, I activate FLC mode and monitor the trend in the airspeed tape. The aircraft will adjust pitch to aquire the selected airspeed, I have to do my bit as pilot by monitoring the trend indicator and adjust power to match the trend. Once the power setting and pitch angle match the airspeed, I leave well alone and simply monitor. If I am cleared to a new FL or altitude I select an appropriate VS and adjust the power to match my desired airspeed. I find that it is all about power and pitch to match my selected airspeed.

There are some very good YT videos by Jesse Flies. He pilots the 300 in and out of various airfields in the US and Mexico.

Best Regards...Ken.

Yes YT Jesse flies was a great Phenom 300 source of info, unfortunately for us he went on to the airlines. Your narrative is good and very close to mine. Still waiting to hear from jfrex about the mod.
