Hmm, I'm getting really frustrated with myself, as I'm sure it's down to my own 'finger trouble.' I loooove the Q400, everything about it sits really well with me, and the wonderful sound set when the engines roll to life is awesome! Anyway, I find the aircraft really difficult to hand fly and I'm unsure whether it is down to the weight/fuel/load distribution or if in fact it is characteristic of the aircraft. I always feel like the aircraft is on a water bed! She floats upwards and downwards like a bowl of jelly.Trying to trim her into level flight and adjust the throttle always seems to be a hard task for me. I find the whole affair of manual flying her a real task. Does anyone else share this frustration or is it just me? Is this pertinent to the specific FDE of this aircraft? Is there anything I can tweak that could help alleviate this effect, I'm thinking of perhaps a heavier load?? Anyway, some input would be appreciated. Thanks fellas.

Howard, she's got masses of excess power (just like the real aircraft) and I found (and still find) levelling off smoothly at the target altitude after climb-out is challenging without using the automation. Manual approaches however have always felt fine provided the aircraft is trimmed properly and I keep an eye on the speed. (Gentle touchdowns however are another challenge - again just the real thing!)

 

One foible of the Dash 8 is that the aircraft requires not only elevator trim, but also rudder trim with power adjustments.

 

Not sure if this helps much, but hopefully someone better qualified than me will be able to provide some pointers.

 

Cheers,

Nick

Thanks Nick for your input. She certainly is a handful!

Make sure when your landing to keep the power on or  else you find yourself in trouble

Hi Pete, sure, I discovered that at my expense on several occasions

Mine is a joy to fly, i always use the Majestic loading application and attempt to get the balance about right.  Speed control is difficult, unlike the NGX 800 the aircraft will slow down well but occasionally the speed can get away from me, both too fast and too slow.  At altitude it runs slanted to the right unless you use about 6 right rudder trim.  The Airline-2-Sim training course helped me.

My Nephew is a Dash-8 Pilot/Instructor with one of the Majors and they do the initial climb out by hand but will use the automation to maintain altitude and to handle both climbs and descents.

It's quite interesting watching some in-cockpit footage of Takeoff's/Landings and the most common call-out is "Alt Sel"  as each new Altitude setting is dialled in and then again as the 1000 to go alert sounds.

He also described the Dash-8 as "it lands like a shopping trolley" but only in the Dry! when the runway is wet landings are much smoother.

They also lower the gear at the same time as they dial in the first level of flaps on landing because the dash has no speed breaks sticking a ton of steel and rubber out into the wind help to keep the speed in check.  

As Ian has suggested above http://www.airline2sim.com/

As Ian has suggested above    http://movies.airline2sim.com/ is well worth it to have  a look

Agreed, excellent series I'm looking forward to the next offering

I've started with the Q400 recently and I can confirm she's indeed a handfull, with a lot of power. The nickname Crash8 has it's reasons.

I'm following the Airline2sim videos and there they also advise to put in some load. Empty with just enough fuel for short hauls she's very jumpy, adding weight does make it a little better. But keep in mind, it's is an aircraft with a lot of automation and it's build to use that.

Howard,

The real thing moves around quite a bit. There are a number of factors to consider. It's not a heavy plane like the airliners, and more vulnerable to winds. It's got a giant rudder that acts as a sail for crosswinds. It has a high wing with tons of lift. It's got giant flaps and landing gear with tons of drag. And it's got giant turboprop engines with tons of thrust, prop wash, torque, and p factor. This all makes for a squirrely affair on takeoff/landing. To counter the props, I use 15 ticks of right rudder trim on takeoff and 5-10 for landing depending on conditions. Even aileron trim can be necessary in this thing to counter- balance the rise of the left wing caused by all that rudder trim. I recommend setting trim buttons on the keyboard for easy access... and, of course, be ready to work the yoke or stick... often, like a mad man.

 

Also, as mentioned before, making sure the payload distribution is correct using the bundled MJ application is literally pivotal to the balance of the aircraft.

 

If you are absolutely hating the experience, you can find the mjq400 ini file and set propwash=0 or .5, it is currently 1. This should settle down atleast one aspect of the fde. You would be removing one of the main characteristics of this plane, however, and cutting short the amazing complexity of the dynamics engine.

 

Edit: come to think of it, that prop wash value in the ini file might be binary, and require a 0 or 1. I'm not sure, maybe others could clarify this.

Hi Howard,

I think this is a different aircraft to all others. Where I hand fly a NGX/777 close to cruise the Q400 is different. PFPX has a profile for it and I set up a flight of around 70%-98% full PAX and some cargo. 

 

Take off is always is way more challenging to a NGX etc because of the toque for one think, you need to rudder trim and need to keep an eye on it, because reduceing toque/power like when you level off  you need to re do your rudder trim. When you take off look how much your slipping and rudder trim it out. Also trimming for VS before AP helps.

 

Take off V2+ 

AP ON

IAS On and set to 185

once at 185 flaps up

IAS 210

 

You do need to use AP with the Q400, Approach and landing, I must be lucky I find it to be a joy to hand fly approachers and landing as long as you know your Vref and land at that speed with power still on grease landing I find easy. I reduce power at touch down never before.

 

I have a new Q400 flow list Howard, if you would like it drop me a email mate, always happy to help.

 

Kind regards

Dave.

I would set the Q400's turbulence scalar to something under .5.  I don't remember what I set it at, but I tuned it in coordination with various conditions in Active Sky based on what I would expect to see, which is quite subjective.  I think at the default value the plane is overly sensitive to choppy air, and so do many others, which is why they gave you the ability to change it.

 

Set the power and leave it.  The plane is sooooo sensitive to power changes.  It helps immensely to have accurate throttles, and if your quadrants are the least bit noisy than that can be a problem.  I checked your profile PC specs (Rockliffe) and you have a Warthog throttle, so setting the power very precisely ought to be easy for you.  On approach, set that torque at 18%, and only nudge it from there, in the smallest possible increments your throttles will allow, or else you'll be all over the place.  The only reason the Q400 has wings is to mount the engines on.

Thanks for all the feedback fellas, very much appreciated.

Yup, done this and while I agree it has changed the FD somewhat, I certainly feel it is more manageable. Thanks

Dave, you sent me the flow chart some time ago, thanks.

I'll try that, it sounds very interesting, thanks.

Not the same one, don't mess with the Q400 :(
