How to flare this beauty?
Hi guys, starting to fly this beast a couple of days ago and still learning the flows and the systems of the Q400.
My first two landing was like very very hard, after pitching +2° up below 30 fts AGL, the vertical speed barely moved and i smashed the ground at -600ft/min. My third landing, i started to preflare at 40ft and then really hold back some back pressure from 30 ft until touch down reaching a pitch attiitude of 5/5.5 °on touch down but my vertical speed was still in the -200/-300 area. I know it is an acceptable firm landing but still.
I also find the q400 to have a lower pitch rate when passing 50 ft but to my knowledge that could be explained by the ground effect that will make the aircraft more nose heavy and also kill the vertical speed.
I watched a couple of videos and q400 pilots were able to make greasers and seemed to start flaring at 30 feets

Landing in the correct spot is far more important than getting a "greaser". The FS community places far too much emphasis on so called "greasers" but if you are using half the length of the runway to achieved it then it is not a good landing. I would suggest that because the Q400 has such a high wing the ground effect is minimal but the effect of prop wash on lift is huge. As soon as you idle the props the wings lose a substantial amount of lift. I heard once that Q400 pilots leave some power in on the flare to prevent the well known hard landings.
I do know that but there is a difference between landing at -50ft/min and -600ft/min.
I only put the PL in Disc then Reverse after touching down
I found (no idea where) an interesting article about landing the Q 400 and try to attach this document for you.
We have a detailed document provided by one of our tech pilots regarding "Landing the Q400"
Cheers
Yeah i saw it yesterday, actually the pilot said to apply power dsuring flare and i've seen a video where the pilot went from 16% torque to 22% torque during flare and made a nice smooth down down, gonna try that
I strongly agree with ferrariman15. When watching greasers in replay I sometimes ask myself whether or not the weight on wheels switches would be activated at all at such low vertical speeds. In general I only go for a greaser if there is lots of runway in front of me and if using the most part of the runway doesn‘t lead to a significally prolonged taxiing.
Greaser or not, the following aspects helped me improve my landings over time (mostly in terms of accuracy):

all of the q400 videos i've watched, the PF made a greaser
Keep in the power until main wheel touchdown, be at Vref + 5 (or gust/wind additive, whichever is higher), at latest when passing the runway treshhold, focus your view at the far end of the runway to get a better feel for the closure rate, initiate the flare around 15° by a slight pitch increase (do not exceed 6-7°, 8° WILL end in a tailstrike), touch down roughly at Vref. Avoid excessive flaring and/or pitch inreases. If you notice you are sinking too fast (speed is getting low), increase power slightly. If you feel a float or observe a too high speed after flare initiation, reduce power slightly (do not go to DISC however). Hope this helps and a rough guideline.
15 ft, thats late no ?
Yes that late. Unless you want to extend your flare too much and flaot down the runway. Of course you can arrest your descent rate at 50ft a bit if it's a tad high.
at 50 fts, i already feel the ground effect on the Q400, its getting very nose heavy, i have to hold backpressure just to maintain the flight path. In video ive seen, i never saw a pilot in the q400 flaring below 30ft RA, they even add 5-6% of torque below 20ft RA
even when flaring at 30, adding 4-5% torque, i smash the ground at -400. I am at Vapp/Vapp +5 and -700ft/min, starting at 15, i would smash at -700/-600
You can see that he add torque at 40 ft:
Are you flying the Vref + 5 (or gust correction) speeds? I never have hard landings in the Dash, my average is around 50fpm usually.
Jesus thats a greaser -50ft/min
I maintain yes Vref +5 ( around that).
Nah the engine are quite sensitible and Q400 pilot that made the flaring manual for majestic suggested not the try to maintain perfectly Vref. I maintain speed between Vref and Vref +5 kts.
I noticed two different ground effect witht the Q400:

I understand you are new to the Majestic Q400. But one thing to keep in mind is that it will behave little differently each time. Depending on how much speed you have during the flare, your TRQ setting and if you are properly trimmed, are just three factors to consider. You will not find one golden recipe for perfect landing everytime in the MJC Q400.
But I make sure to carry at least vref+5 into the flare. That is minimum for me.
20ft-15ft RA start flare, I very rarely add TRQ to arrest sink rate.
This works for me, some tweaks here and there depending on current conditions
I say the most important part is keep on practicing and get proper feel for the aircraft, more so than mimicking Youtube-clips.
Are you using the 125khz control mod btw? Maybe it can make things easier in your case?
One of my landings in an older version of P3D. (not saying it's perfect by any means, but you see how I do in sim)
thanks no i can't use the 125Hz as it's not compatible with my brunner force feedback yoke ?
do you have Chase plan by the way ?
I really noticed two different behaviour starting at 500fts
and all was identical only the second time, it has a bit less fuel do to the go around
on our video it looks very realistic
I fly the Q in real life. In my short time flying this sim it's not exactly like the real plane. I'm using the DH8TOLD app to find my Vspeeds and I'm skeptical about them, the attitudes don't seem to match up with the actual aircraft, maybe that's just me getting incorrect numbers.
In general, the norm is Flap15 landings, reduced Np landings unless there are operational requirements (crosswind, turbulence, short strip, icing, etc). In calm conditions, we either bug Vref and fly Vref+5kts, or we bug Vref+5kts and fly the speed bug. Usually that puts the nose right at or slightly above the horizon.
In terms of the flare, in general the flare sequence flare at 20 feet. At 20 feet I add in just a touch of power (~1%) and bring the nose up very slightly. We call this increase in power "walking the throttle up" because you have to be very gentle with it. Eyes should be outside during this point, as in real life you would have a pilot monitoring calling things out for you. We have call outs at 5 degrees nose up, which is an alert call, and then a 6 degree nose up call, and corrections/go around may be needed at this point. Tailstrike is about 6.8 degress nose up (correct me if I'm wrong, I haven't been flying for a while).
One technique we use is listening to the 50, 40, 30 calls. The closer they are, the faster you are sinking, if it skips a number you are really coming down fast.
Landing this plane in real life is hard, inconsistent at best. You will have a week of good greaser landings, followed by a month of not so good ones.
