Landing is incredibly difficult

Recommended Posts

I've had this plane a few days and love it so far (After downgrading to Windows 7).

 

However, I find performing a smooth landing nearly impossible. I trim correctly (I think), and use the calculations on the table to get the correct approach speeds, however the plane becomes incredibly unstable and starts violently pulling to the left and the vertical flight path starts to become really difficult to control once I'm at the last 1,000ft or so. I then find it really difficult to maintain the correct speed as it either starts to climb or on a few occasions I end up slamming into the runway being unable to flare or simply being too high and going around and trying again. I've also noticed in videos on YouTube then others seem to have the same problem.

 

Is there a trick to landing this plane that I'm missing. I've never had this much trouble with any other planes in FSX :-)

Try landing with Flaps 15 and 10 knots higher approach speed.

 

I find this plane is very controllable until you get close to stalling speeds.

Yep same here :-) vref + (wind 1/2 steady wind + difference in gust to add) and max 20kts)

 

Example 270/12 and gust 17 and vref 117 gives 12 * 0.5 = 6 + 5 (17-12) = 11 vref 117 + 11 = 128

Sounds like you're trying to use too high of flaps, and having to use a lot of power to drag it in, and with the torque effect accurately depicted, it's yawing to the left from the propellers. As they suggested above, use less flap, higher speed (but not high enough that you're left in ground effect and float halfway through the runway before you touch down) and land the plane. It really is a difficult plane to land, it either has to get put down, or you get caught with a shortage of speed and power, and hit the ground pretty hard.

Keep power on @ <125knts flaps 15 until main gear down then reduce power. Not like other planes where you cut the power before flaring. Its apiece of cake after a few practices.

Thanks for the info guys, looks my mistake was I am approaching too slow and I'm using too high flap settings. Will keep trying :-)

Using a high flap setting is not your problem. There is nothing wrong at all with full flap landings, that's what it's designed for.

 

Your problem is that you weren't aware that the Dash is a "power on" landing aircraft. Pull back the power as you usually do with other aircraft, and the prop blades will be flat on to the airstream, thus the plane will sink like a stone.

 

Keep power ON, as the poster above suggested. Power back AFTER the main gear touches down.

 

As for the yaw to the left, this is said to be a characteristic of the real aircraft. You will have to decide for yourself if you think Majestic have modelled this accurately, or a bit over the top. As non Dash pilots, we have no idea.

 

If you are using a joystick, and thus find the propwash effect less than desirable, resulting in the aircraft pulling to the left, it can be disabled.

 

I prefer it disabled personally, we don't have to be slaves to realism. If the hardware we are using, or personal preference dictates otherwise, a minor mod is no big deal.

 

Simming is about enjoyment.

Many operators land using Flap 15... just make sure to set the landing flaps knob to whatever setting you actually use to avoid the GPWS warning kicking in...

 

As others have said, power must be kept on until the main gear have touched...

 

Practice... like I need to! :)

@martin-w. Thanks for the info, that makes sense now, and I can see what I'm doing wrong. I'm cutting out the power as I pass over the threshold just before the back wheels touch the runway and then the plane just drops like a brick. :-)

Here is me perfectly landing after the difficult approach to LOWI RW08, you just have to learn the proper landing technique, which is exactly the same as in the real Dash-8, that's why Majestic software Q400 is the benchmark in the flight simulation for the moment.

Nicely done, you make it look so easy. BTW, what is the scenery you are using for Innsbruck?

Thanks, I am using Aerosoft Austria Professional X for the mesh, textures,landclass and Aerosoft Approaching Innsbruck for the airport. Innsbruck and London City are my favourite airports for the Dash 8 in Europe.

Also learn how to use approach mode, it works like a charm. And practice,practice,practice..;-)

Superb landing Peter, I have subscribed by the way..;-)

When I first bought and flew this plane, 2 weeks ago, I was like whoooahhh, forget 10 years of flight simming;   I cannot land this plane!

 

Now 2 weeks later, hand on heart, almost every landing is a greaser :smile: ... the factor was as Martin said above, do not retard the power levers, until your main (back) wheels have fully touched down.   The props are huge on the Q400, and when they're not generating torque; they are immediately generating huge drag.     Once I realized this, and also that you must be established on approach (in terms of trim) by 500' in this aircraft, I nailed the landings.

 

PS... I do agree that Flaps 15 gives a far more smoother landing than 35.

Thanks guys. I've successfully done two flights today and landed alive, EPGD (Gdansk) to EPPO (Poznan), and then EPPO (Poznan) to EDDM (Munich). The first landing was smooth, and as everyone has said, the trick seems to be keeping the power until the back wheels have touched the runway and then going to idle. With my second landing I floated a little bit so still need some more practice.

I'm not sure in regard to flap 35 and smooth landings.

 

I landed at LOWI yesterday, with flaps 35, and it was one of my smoothest landings ever.

 

Need to try a few more I suppose.

Thank you, I have a new video and a new challenge for all of you who want to master this magnificent aircraft. This time it's the most challenging approach for a commercial turboprop airliner in Europe, the approach to Isafjordur rw08.

That was insane. For a minute I thought you were using LBS instead of KGS and thought you'd be gliding it all the way down.

 

But that approach looks great. Especially with that hazy/foggy/drizzly weather. Nicely done.

I agree with Mike, that was intense, great video Peter! I too would be interested in that route.

Thanks once again, now about the route as I am pretty familiar with it. There is only one route to and from Isafjordur, it's flown by two airlines Icelandair ( the main airline in Iceland ) and in the last years by the regional Air Iceland. The route is from Reykjavik: BIRK - SID: RATSA ( above 3000 ft ) - MYRAR ( at or above 5000 ) - SKALM - then - RE- between 6100 and 4500 ft where you start to descend to -OG- ( 2900 ft- min 800 ft ) and finally -IS- between 1000 and 800 ft where you turn to heading 262 to BIIS. The types of aircraft used are Fokker 50 and DHC 8 - 100 series only and if you are one of the few who had the chance to experience it as a passenger in reality you'll will never forget it ( see the video below ). But I can assure you one thing, properly landing there in a PC flight simulator for an experienced pilot is way harder then in reality ( I witnessed it yesterday, but promised not to talk publicly as the result was pretty embarrassing :) .

I do apologize for the bump, but this is something I felt like I needed to correct. The ECU varies prop pitch during power changes and with low settings, it coarsens it automatically with the governor. It feathers itself to maintain an incredibly low drag profile.
