  1. 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.
  2. 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.
  3. 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.
  4. 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...
  5. 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... .
  6. 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.
  7. 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:
  8. 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.
  9. Aim for 300-500fpm for passenger comfort, 1000fpm can be quite uncomfortable for the people in the back .
  10. 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.
  11. 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.
  12. 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.
  13. 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.
  14. On the other hand, you can downright trim it to perfection and fly hands off if the weather isn't too adverse...
  15. 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 .
  16. Alright, after hearing that I can buy & test the aircraft in the demo of X-Plane, I decided to buy it. Even if it's not up my alley, I do like supporting small developers, and anyone making a Jetstream has a star in my book . Having said that, here's a list of things I noticed in the 30-60 minutes of quality time I spent with the addon.... Please note, these might not be bugs, but developer choice, sim limitations or just things in which the addon differs from my experience with real J32's. Cockpit Cabin lights... why are they not linked to the cabin light switches on the panel? The manual mentions that the normal way to turn them on is via the galley in the back, but the cockpit has Cabin Light switches in all planes (I've been in at least). Developer choice to put them on the yoke menu?Reading lights switch... It's meant to activate the reading lights in the cabin, so passengers can use those for ehm... reading . I was kind of suprised when I turned them on and the cockpit lit up, haha.Panel Master Switches... would it be possible to just let these switch off the panel lights instead of acting as backup Avionic Master Switches (if I read the manual correctly, that is their current function)? The Avionic Masters aren't that hard to reach from the co-pilot seat in my humble opinion (both in the simulated cockpit and in RL). Turning each section of lighting off is quite time consuming during flight though.Speaking off the lights... On real aircraft there is a panel flood light switch, located on the left of the mode selection buttons, which controls the bright panel floods. In the addon they are controlled with the Left/Center/Right switches. One switch could be easier perhaps?Temperature control... Ok, this might be going in a little bit too deep... but with temperature control set to Auto and the Temperature Selectors full left (default position), cabin temp should be about 18C. The temperature selectors have a range from 18C at the lowest position to 23C at the highest. So 25C is a little bit much.Gear horn... the inhibit button is there and functional, but the horn itself does not seem to function as it would in the real aircraft.Very small one... the flap control CB reads FALP . Flight Model Overall it seemed to be a little bit too nervous and quick to respond. This might have to do with my joystick setup, but at some points roll rates just seemed way too high. It also doesn't change speeds as quickly and easily as a real one can do. So take care to slow down sufficiently for approach, perhaps plan your descent with a little bit of level flight at the end to lose speed. Speed seemed to be quite high in most cases as well, but I will have to check into that a bit more thoroughly.The pull to the right is just plain awful and not realistic in any way. I don't know if this is a general X-Plane issue of developer choice, or a combination of both. Whatever it is, it makes the plane almost unflyable for me. A couple of times, even full left aileron trim wouldn't stop the aircraft from rolling right. The only time I have ever had to use full aileron trim in the real one was during engine failures/V1 cuts in the full motion sim and simulated engine failures during proficiency checks. In the end, I quite like it, but I will not purchase X-Plane to fly it unless there will be some changes in the flight model, particularly the yaw/roll to the right. Still, standup job!
  17. Ah, I was not aware that addons would work in the demo mode of X-Plane (that's what you get for being an X-Plane noob). That would make it less of a costly affair to check it myself . I'll go download the demo then. Apologies to Javier as well if I came off too critical, I really respect the job he has done. It's probably not the first thing you want to hear in the first week after release, me coming around and basically saying this is wrong and that's wrong . For me it was just trying to determine what I could expect. But I fear I have kind of derailed this topic .
  18. Anti-ice is basically what you turn on when the outside air temperature is within icing range and there's visible moisture (clouds etc). Continuous Ignition is usually used when there is also (heavy) precipitation present, like flying through rain or snow. Some Jetstreams have the combined option, others have a seperate Ignition switch. So basically, whenever you're flying through precipitation, you switch from Anti-ice to Anti-ice/IGN.
  19. For reference with the real aircraft.... Speed limits for the flaps on the JS32 are: 10 - 170kts 20 - 160kts 35 - 150kts And max gear extension speed is 160kts. If icing is suspected, use max flaps 20 and increase Vref with about 10 knots. This should normally work out quite nicely in the real thing, so you can give it a shot in X-Plane. The 130-140kts that cruster mentions is more in line with my experience. You should see between 35% and 40% torque (again, in the real aircraft). I've been kinda turned off by this addon. Basically because I want it to be as real as possible (within the limits of the sim), while the developer point of view does not seem to match that desire. And since I would have to purchase both X-Plane and this addon (and neither have refunds as far as I can tell).... It's kind of a big investment for an addon that might not match my expectations . I hope you guys don't mind my constant references to the real aircraft, let me know if it's too much. I don't want to come off as a random guy showing off what he knows... I'm just interested in your experiences and how it compares to mine in the aircraft.
  20. Looking very good! Would it be possible to provide a version later on without the wire antenna running from the fuselage to the tail? It's quite rare on actual Jetstreams as far as I'm aware.
  21. Yes, all digits are limited to a range of 0 to 7 on real transponders (if I understand your question correctly).
  22. Ok, thanks for the information. As I mentioned, I'm not really at home in X-Plane, so I didn't know if it was a simulator limitation. Still getting it as soon as I get home, currently waiting for maintenance to fix a Jetstream .
  23. Just my 2 cents about the stick pusher; It is a pretty violent mechanism. At the first flight of the day you also check stall protection. First left button to test, next right button, then both to activate stick pusher. When testing the stick pusher, you better hold on tightly to the yoke, or it will slam into full down pretty hard. There is no gradual motion in 1,5 or 2 seconds.
  24. Ok, clear explanations. - I was only aware of the 23,5V and 24V limitations, have never heard/read of the 20V one. But you never stop learning . - The only thing we can really set before engine start are radio frequencies. In the planes I fly, the GPS units are linked to the Avionic Masters and will forget any input if you turn those off for engine start. But since we have 2 sets of hands in the cockpit, we can easily set everything during taxi. A couple planes also have avionics that might be sensitive to frequency fluctuations that can occur during engine start. - Resetting the generators... maybe something for me to learn again. I will ask around to see if any of the other pilots do it/used to do it. - Ok, I will just have to remember, haha. Is it possible to edit the default configuration though? I am not very familiar with X-Plane, but could I set the HYD shut-off and LP to open by default? - Ah, clear story. I don't want to try that on the real aircraft, the starter/generator would probably start eating itself up trying to move the blades while they are in feather position . - The fuel pump stuff is just from all the documents I have here. They say that they should be on for TO, and we never have them off for TO in RL either. And indeed, 2 pilots, 2 procedures. I will stop bothering you with this stuff until I have bought the addon myself, haha. Just a bit too happy that there is finally a nice rendition of the plane I get to fly on for a living. So again, great work!
  25. I do not want to speak out of turn since I don't have the addon yet. I'm just excited to get it onto my regular system after coming weekend, so I'm hanging out here hoping to help, haha. On the pedestal center panel, there should be a rotary dial next to the recirculation fan switch (just move up from the flow selectors). It should read FOOT at the bottom and DEMIST at the top. If the system is modeled you can try turning it to DEMIST. There are a couple of holes on top of the glareshield through which air is blown onto the windows. This might help, if it is simulated of course.
