No, they should go on as soon as you have the throttles in a position below the flight idle gate. Does not matter if it's in flight or on the ground.

It's not so much the presence of torque roll, but more the amount of trim required to counter it. Sure, physics dictate that torque roll should be present with the prop config that the Jetstream has. But on the actual aircraft it's near non-existent. I've mentioned this on these forums and on different forums as well. If you've flown the actual aircraft, this simple fact ruins the simming experience. If you haven't flown the actual aircraft, you will get a wrong impression on how it would fly from this add-on. The last time I tried the addon I had to set over half scale aileron and/or rudder trim for a somewhat level takeoff. In the actual aircraft, those two will usually be set to neutral for takeoff (rudder trim tab is set 7 degrees to the right if you have a neutral indication in the cockpit). You will almost never get near half scale trim deflection in normal operations. I think this is a genuine issue, whether it's the addon or X-Plane itself doesn't really matter. What does matter is that you shouldn't consider it a realistic simming experience as long as the issue exists. It's a beautiful addon, it's fun, and might be considered a challenge, it's just not realistic.

Every single Jetstream I've flown so far has none to very minor roll to the right at maximum torque. I've been told this is part X-Plane bug and part "feature" to make it more challenging. Difference of opinion, I don't find having to put in full left aileron trim for takeoff challenging. The autopilot was overwhelmed by it on a test flight a while ago as well, sending me belly up into a nosedive once it couldn't control the roll anymore... Yes the right engine is critical, but you won't notice any significant roll or yaw unless you start getting into single engine situations as Cooley mentioned.

I think the uncommanded roll will keep you plenty busy. It stumps the autopilot sometimes as well, couldn't keep wings level with full rudder and aileron trim...

Yes, mostly passenger comfort. Even though 8000ft cabin altitude should be no problem for passengers (it's a common cabin altitude for larger airliners for instance), there's no real benefit to setting a higher cabin altitude, at least not that I'm aware of. You might reduce stress on the airframe, but those are rated for a number of pressurisation cycles anyway, whether those are to max differential or not. One thing might be if you want to make your passengers a bit easier to handle... .

Well, generally speaking you would go for the lowest option. Not much sense in having a really high cabin altitude if it's not needed. So I would say just go for 2000ft or 2500ft.

That's the point where the addon stops being true to the real deal. The "Airplane alt. at max diff." is meant for the small subdial at the bottom. With the addon, it is non-functional. The normal range for cabin altitude is from sea level or 1000ft above field elevation to about 8000ft at FL250. With 8000ft at FL250, you will be near maximum differential pressure. For FL200, a cabin altitude of 5500ft will give you a differential pressure that's very close to the maximum differential pressure. So take a safety margin and set it to 6000ft or 6500ft. Maybe this will help:

The way the add-on is set up doesn't correspond to how to use it in the real aircraft (not trying to bring the addon down, just stating a fact). The dial that indicates the cabin altitude has a subdial at the bottom that indicates the maximum altitude. For climbing, you will normally set it to 1000ft above your filed level. So if we're flying at FL150, we set the subdial to FL160. This keeps a nice margin for the maximum differential pressure. The airplane can keep sea level pressure up to about 13.000ft or FL130, so any flight below that you can keep the pressure set to field elevation or 1000ft above (see next part). For descent, it's common procedure to set the cabin altitude to 1000ft above airport elevation, and correct for temperature and QNH. What this basically ensures is that when you're at 1000ft in the approach and stabilized, the cabin should start descending as well and you can slowly close the flow selectors for a nice transition between pressurized and outside pressure.

Aim for 300-500fpm for passenger comfort, 1000fpm can be quite uncomfortable for the people in the back .

Try reducing RPM to 97% percent at about 1000' AGL. Keeping them at 100% creates a lot of drag you don't need. And you won't have to worry about running RPM too high.

Not sure if it applies to the addon as well, but in real operations you need to turn on the fuel booster pumps above 20.000ft/FL200. Might want to check that out.

Don't know about MSP, but I do know that after leaving the aircraft for 6 hours in -20C without heater, the aircraft is freaking cold. As in, put on some gloves or your hand will freeze to the yoke cold. In our operation we have heaters hooked up to the ground power heating the aircraft most of the time in cold, cold weather. To get the cabin to a decent temperature takes anywhere between 5-15 minutes. And no, the instruments and labels are not that yellow. The instrument lighting is a bit of artistic liberty in the add-on I suppose. The instruments themselves usually just have one or two simple light bulbs integrated or sticking out of the panel to provide some illumination. There's a panel flood below the glareshield which helps illuminating any text labels, a general cockpit flood behind and above the captain's seat and the lines and buttons you see lit up on the skirt panels and overhead are a bit more white in the real aircraft.

Yeah, normal operating range is between 55 and 100C. Oil Cooler Flaps to Auto/Normal should automatically close the oil cooler flaps when the temperature is getting too low. Minimum required for takeoff is 55C as well, and you should have no problem reaching this even with an outside temperature of -20 or -25C on the ground (speaking from experience ). At level with temperatures down to -40C I've yet to see oil temperature go below 60C. Cold weather is lovely, great performance.

On the other hand, you can downright trim it to perfection and fly hands off if the weather isn't too adverse...

I understand your point of view a bit better now as well Javier. It is just different from my approach to simming, but that's something personal. Yes, there are also a lot of similarities between the add-on and the real thing. But since it's a simulation and that's supposed to be the case, I didn't point them out .Still, I will try to refrain from sounding too negative, since I am also a bit biased due to the experience on the real aircraft. What you created is miles ahead of the only other J31/32 addon I'm aware off .
