I’m flying KA350 almost exclusively (at least in the game) and I don’t think I’ve experienced most of these, at least not to that extent and not consistently. I’ve read feedback by other people who are saying that it’s very hard to slow down the airplane during arrivals (mostly because propeller drag is not modelled in the game) but I can’t say I had this issue.
My usual method of descending from cruising altitude is to set a VS rate of about 1200fpm, then set throttle to around 20-30%, propellers to around 30%-50% (aiming for 1500-1550rpm) and lately I keep condition level to low idle (used to have high idle all the way but I’ve changed that habit). Gradually I may decrease VS to around 800-1000fpm when I’m under 8000-10000 feet.
The above configuration ensures my speed decreases from 200-210KIAS at FL250 to around 180KIAS at FL050 minutes before the final approach and this is when I’ll lower flaps one notch which will further reduce speed and will allow me to reduce gears. As soon as this is done and I’m also established on the GS/GP then I’ll lower flaps again and this’ll send me straight into Vapp speed range (115-120 KIAS) from which Vref is achievable if you simply decrease throttle or even set it to idle).
When I was flying with cond level high idle, I would sometimes switch to low idle to bleed speed but not often. Also I used to always go to full reverse on touchdown but not anymore (it only needs to be used for short runways).
It’s true that sometimes during landing or even taxiing, both N1 and prop RPM go crazy without you changing anything and you can tell by the high whine. Usually this happens after I’ve touched down. My workaround is to switch prop levers from 100% to around 50% and then back to 100%. Most of the times this does the trick and both N1 and RPM decrease. Not sure why this is happening.
This is happening to me too. Curiously it ONLY happens during taxiing after landing but not during taxiing before takeoff, even when weights are comparable (e.g. you’ve made a really short trip). I’ve read that in real life, KA350 will start rolling out even at idle throttle but this is not the case in MSFS. Before takeoff you always need significant amounts of throttle to get the thing moving (especially when you’re nearing MTOW) but after landing this behaviour changes completely and it takes lots of messing with throttle/prop levers to keep N1/RPM low and lots of braking. I never have to use reverse thrust though.
To summarize the above, KA350 is much more problematic than the other MSFS turboprops and the propeller drag issue (or lack thereof) is a game breaker for many. Personally I doubt that Asobo will ever focus on fixing or improving any of the above, so I’ll wait for a 3rd party to release some proper study level version of the plane as they’ve done to other sims.
I’ve voted for this.
