This is more of a question with regards to BETA throttle positioning during Taxi operations. I am not a "RWP" but have been flying Sims since the C64 days. I notice that most of the MSFS Turbo Prop aircraft, specifically the TBM930 & now Kodiak, tend to stop (some actually back up) when entering the BETA position. I was under the impression the BETA position was used to slow taxi speeds prior to going into complete reverse thrust. Is this action really correct? It's really pronounced with the new Kodiak since taxi speeds increase rather dramatically when outside of BETA and the minute you drop into BETA it will completely stop movement in a very short period. I have another TBM, in another Sim, that this feature does seem to allow continued forward movement while in immediate BETA position, (this is not a flame throw either I use both 😀) just wondering which is correct.

All thoughts are welcome and especially if you are a RWP with Turbo Prop background..

None turbine pilot here, but there is good video of Kodiak taxi. It appears to me shows  conditioner low idle, high rpm, and throttle around idle

 

I'm not sure, his throttle looks to be well into the BETA range during taxi just before the hold short. Really hard to tell there though.

I've seen Kodiak RWP use beta for breaking during taxi

Pulling the throttle slowly into beta range while taxiing, allows the pilot to control the taxi speed without having to use the brakes. Hard to set throttle up to do that in MSFS.

Good point and I would imagine that would be the case for all TProp situations during taxi. My main concern is the instant you go from Flight Idle to BETA would the aircraft come to a rather abrupt stop then begin backing up or would it just slow its forward momentum depending on how far you drop into the BETA area of throttle.

This is how I interpreted the process to happen. I hope MS/ASOBO can work some magic in sim to provide this ability. Thank you Bobsk8.

If you are in beta, with just a small amount of throttle in beta range, it will slow down. Increase the throttle in beta range and you can stop and even taxi in  reverse at full beta throttle. 

I flew the Majestic Q  400 for a few years and could easily control taxi speed with beta range.

As already discussed in another thread - BETA/Reverse is broken since SU7. You can go into BETA only with the command "Decrease Throttle".

Using this will result in full BETA mode and you are not able to adjust the power as you go direct out of BETA trying to do so. This behavior leads to stop or even backup the ac in BETA.

Before you could use commands like toggle BETA and adjust the BETA power with the power lever (I have a HOTAS Warthog).

IRL mostly used for convinient taxi speed or manouvering (esp. for ac with 2 or more turboprops in "close quarters").

Best regards

Have used beta reverse a lot in SETP's and it accomplishes a couple things: Super useful when taxiing and hitting black ice on the ramp! Has actually saved us from sliding into a snow berm when the brakes locked up trying to slow down. You won't find that in any manual 🙂  Generally used to slow the plane down on the runway after landing, as opposed to burning up the brakes (those pads are not cheap). Occasionally used while taxiing but not a whole lot (depending on the plane, wind, slope etc.) and usually just to slow before stopping at hold short bars or intersection. Have used it to backup on occasion when holding short, and a commercial flight needs to squeak by for IFR release time. Always fun to ask the guys to 'watch the tail' for that. All that being said it is a great tool that is a real advantage over jets of similar size.

I've seen someone setting the condition lever to low-idle when taxiing. Is that plausible?

Yes, you stay in low-idle for taxi.  High idle prior to takeoff.

Thank you. I tried it and I find the taxi speed much more manageable with low-idle.

You don't even need high idle for takeoff, unless short runway, heavy load etc.

Has anything improved regarding turbo prop controls ?
