Almost all the functionality of the Perspective is implemented.

GCU Keyboard needed a change in FG1000 and canvas.PFD to support keypresses. I've sent a patch to Stuart who said it will be on "next" shortly. Adding waypoints using the keyboard instead of the damned FMS is wonderful!

@D-ECHO: Stuart asked me If it was possible to add the GCU in FG1000, but I'll need to extract the 3D model from the interior, which was made by you. ¿Are you alright with that?

Still struggling with the FDM. I've uploaded the last attempt to the github repo (https://github.com/bartacruz/SR22T) with hopes that somebody will look at it and point me in the right direction.
Adding the turbo, makes the engine go and mantain 36.5" MP but the speeds are not wright. The plane climbs like a rocket, 2000+ FPM at ~190kts :shock:

I've fiddled with volumetric-eficiency, and bsfc and boost-loss-factor, but since I couldn't find real data for the engine, it's all trial-and-error....

Here's my last approach:

Code: Select all
<piston_engine name="TSIO-550K">
   <minmp unit="INHG">         10.0 </minmp>
   <maxmp unit="INHG">         29.5 </maxmp>
   <displacement unit="IN3"> 550 </displacement>
   <maxhp>        315.00 </maxhp>
   <cycles>         4.0 </cycles>
   <idlerpm>      700.0 </idlerpm>
   <maxrpm>      2500.0 </maxrpm>
   <sparkfaildrop>  0.1 </sparkfaildrop>
   <man-press-lag> 0.1 </man-press-lag>
   <static-friction  unit="HP"> 1.57 </static-friction>
   <starter-torque> 252.00 </starter-torque>
   <starter-rpm> 1400 </starter-rpm>
   
   <stroke unit="IN">  4.25 </stroke>
   <bore unit="IN">    5.25 </bore>
   <cylinders>        6.0  </cylinders>
   <compression-ratio>  7.5 </compression-ratio>
   <volumetric-efficiency> 1.05 </volumetric-efficiency>
   <bsfc unit="LBS/HP*HR">           0.5683 </bsfc> <!--18.3 gallons per hour at 85% power = 113.46 lbs (AVGAS) per hour at 267.75 hp-->
   <air-intake-impedance-factor>0.18</air-intake-impedance-factor>
   <ram-air-factor>0.1</ram-air-factor>
   
   <numboostspeeds>1</numboostspeeds>
   <boostoverride>0</boostoverride>
   <boost-loss-factor>1.2</boost-loss-factor>
   <ratedboost1 unit="INHG">6.58</ratedboost1>
   <ratedpower1>315</ratedpower1>
   <ratedaltitude1>18000</ratedaltitude1>
   <ratedrpm1>2500</ratedrpm1>
</piston_engine>


Any pointers will be welcomed.

Cheers,
Barta

I will have a look later, for now: Yes, of course the DUs may be added to the FG1000

SoImanaged to find a download for the Cirrus SR22 but when I spawn t in it just comes up as some sort of foam yellow and blue glider thing. This same thing happens with the A330 addon. Is there an easy was to fix this?

From where did you download the aircraft? If you used a github link, be sure to remove "-master" from the folder name.

You can either download it within the launcher (i.e. from FGAddon), you can download it using SVN directly from FGAddon, or, if you want to use barta's work on the displays, get it from his repository at https://github.com/bartacruz/SR22T, either via "Download ZIP" or using GIT. When using "Download ZIP", as the branch name barta uses is "barta", make sure to remove it from the folder name, so that it is just "SR22T".
