Nose is supposed to pitch up more for the same flight path angle as speed slows, as AoA increases.... that is 100% correct.

Be careful what you change though.

I have this situation with my Q400
As if the whole center of the plane didn't show up. Someone knows what could be causing this

Looks like the interior isn't rendered. Exterior and interior are separate models IIRC, and whether the interior gets rendered depends on the current view, I think. FG only renders the "visible" side of any polygon, so the outside of the hull isn't visible from inside the aircraft.

First thing I'd check, though, is whether your aircraft model is installed into a correctly-named directory. If the name doesn't match, then FG might be looking for the 3D meshes (the AC3D files) in the wrong place.

I checked everything, and it's still the same, interestingly other planes are working properly

Only thing I can think of - try hitting the 'c' key? On some aircraft - not all - that toggles the 3D cockpit on and off. It may be that? :?

If that doesn't fix it try redownloading it - its rather wierd though.

Edit -- from D-ECHO on discord:

For everybody that experienced problems with the QSeries 3d-model: This bug is confirmed, it is present in all current versions due to a change in the FG program. Should be fixed soon, will let you know


And later, he says its fixed -- so definitely redownload.

Three questions here:

- The QNH knob doesn't seem to work. In fact, there doesn't seem to be a knob there at all, just the spot on the panel where the knob should go. Ctrl+C reveals it as clickable, but clicking it doesn't seem to do anything. This makes it impossible to set QNH to anything but the default 1013 mmHg. Is this a known bug?
- It looks like LNAV isn't implemented, is this correct?
- The PFD doesn't seem to display the currently-set autopilot mode, although the autopilot dialog does. E.g., clicking the HDG button on the glareshield panel does seem to put the autopilot into HDG mode, and turning the HDG knob makes the aircraft turn to the desired heading, but the PFD still displays ROLL HLD. Bug? Missing feature? PEBKAC?

Other than that, lovely. Nosewheel steering is much better now, I can taxi the aircraft without problems now, even at a fairly small airport (EDLN) with taxiways designed for smaller aircraft.

You can work around that using a dialog, IIRC that should be "Instrumentation" (it has been a long time since I used FlightGear.)

This is a new bug, which I haven't noticed before. Fixed in svn and git.

LNAV is implemented, use the "NAV" button. Remember you need to have a route set and activated.

This should be working, although not all modes are yet displayed correctly. Autopilot will only work in the air.

The project completely moved to FGAddon. You can find the current version at https://sourceforge.net/p/flightgear/fg ... t/QSeries/
Thanks for the reminder, I have now updated the wiki page.

Hey Echo,

Test flew your latest version of the DH8D. Great work so far (as usual :D )!
However, once airborne the throttle went mad in the NTOP/MCL setting (with PROP 900). The engine dials went off the scale and the propellers started stuttering.
I tried various PROP settings, but the engines just wouldn't behave. Did I forget anything on startup?
And then there is climb performance in the MCL power setting. With standard payload and 2.5 tonnes of fuel it barely reached FL220 @240kt IAS in clean config. Normally IRL these things smoke every A320 from 0-FL100.
I'm off to the airport now :lol:

Hey Sven,

yep, there is something definitely wrong with the aircraft. I have also experienced this but I could not yet find the cause and/or the solution, so I can't fix it currently. I think it appeared while I was trying to fix the performance for climbs, so there's that.... These are things I'd definitely need to adress, but I simply don't know how..

Regards and have fun at the airfield

Hi,
It seems most test pilots here have done their testing with the Q400. As I prefer smaller planes, I have done my test with the Q100. Globally it was a nice experience, and as a result I present here some suggestions for the checklists and other stuff, and also a few bugs.
Just for the records, it was a test flight from Tenerife Sur (custom scenery) to Mogador Intl - Morocco, FL240, cruise speed 280 KT (ground speed).

To be considered for the checklists:
  1. Switch on also the External Power AC (DC is mentioned);
  2. And the positioning / beacon lights;
  3. Mention the control lock position while on ground;
  4. Note that only the bottom part of the starter actually starts the engines...

Considering handling: small inputs with the throttle using the joystick produce large amounts of change in the engines. This can be compensated using the PgUp and PgDn keys, but it could be improved. Also, during taxi, it gains a lot of speed even with condition levers at 900 and N1 around 16%. Remedy is applying constant brakes...

A bug with the condition levers: if the "m" key is applied three times, it goes to fuel cutoff, instead of going to the MAX position. Between the 900 and the MAX, changes are controlled moving the levers with the mouse.
And a bug with the right side PAX door: it can be opened, but does not close!

Request: the engine reverses are working OK, but there is no corresponding sound.

Finally, I suspected the engines were burning excess fuel, but after all it will be just a matter of doing a proper cruise. Anyway, here is the average value:
Speed 195 KIAS; FL240; Fuel burn: 800Kg/h (both engines). In US units: 263.24 gal/h or 1763.7 lb/h. Range with full fuel would give around 900NM. Published range is 1125NM, so it is not far.
