August 1, 200421 yr 1) I was never able to get spoilers to deploy on landing unless throttle was cut IN THE AIR. Touching down with any sort of power added would not deploy spoilers; even if throttle is brought to idle on the ground. However, after landing while still rolling out, disarming and rearming the spoilers will deploy them instantly. This has been discussed. You cannot add ANY POWER here or in the real world upon touch-down because it will cause the spoilers NOT to deploy and for good reason. I don't have issues here. Plus it is already clear many folks simply had some power going and after following suggestions it was fine. In fact other have reported 100% deployment after the patch.You paying attention Martin ;-), while you are here Martin, can you also report to Ariane that RTO IS working on landing, as you are aware this is impossible, please pass that along would ya?

August 1, 200421 yr I know this has been rehashed over and over again, but I thought I'd add a few more welts on the dead horse...Today I did nothing but landings with a 738 into KBOI. All in all I think I did about a dozen landings. Spoiler deployment was very unpredictable. In the end I could not come up with a fool-proof 100% working solution to deploy them (without having to hit / on t/d). However, I do have a few hints that seem to *help* deployment that I have not read elsewhere on here.Note: I have registered FSUIPC and have calibrated in adaquate null-zone on the bottom of the throttle. Gives me about a 21.5% N1 which seems to be equal to using the keyboard.1) I was never able to get spoilers to deploy on landing unless throttle was cut IN THE AIR. Touching down with any sort of power added would not deploy spoilers; even if throttle is brought to idle on the ground. However, after landing while still rolling out, disarming and rearming the spoilers will deploy them instantly.2) On the N1 indicator when changing the throttle position there is a marker of where the throttle is transitioning to. It seems that if you engage the reverse thrusters BEFORE that marker hits idle the spoilers will not deploy.3) I did 1 coupled autoland and my throttle was at idle well before touchdown to make sure it was at idle when the A/T disengaged. Spoilers did not deploy, the autoland also came in very heavy and had some bounce action. Note, this might be because of the fact that when the A/T disengages it will not be set where your throttle actually is until you move it.I always click-drag the spoiler arm to the ARM position and then hit the SHIFT+/ sequence in case. And I also checked for deployment by switching into spot-view after landing; not in an instant-replay or recorded video.Even when trying to be sure to perform all the above and previous posted methods I was not able to acheive a 100% deployment rate.I've read rumors that the new patch, although nothing was changed in the code, has a much improved deployment success rate. Any ideas on teh release date?
August 1, 200421 yr what about the "SHIFT+/ " will this be addressed in a later patch?it is working on the -700 but not on the -800Thanks for an answer X-Plane 11.3x / DCS 2.5.4 / P3Dv4.5 / Aerofly FS 2 Win10-x64 | ASUS Z270E | Intel i7-7700K @4.5GHz | Corsair Vengeance LPX 32 GB DDR4 | 6TB SSD Samsung 850 Pro | ASUS GTX 1080 ROG STRIX 8GB DDR5X | TM Hotas Warthog | Saitek Combat Pedals | Oculus Rift CV1
August 1, 200421 yr Weird ...i've NEVER had the spoilers 'NOT' deploying unless i wanted them to not deploy(t/g)a few comments about your remarks. They are very helpfull to people having this problem i think, so it's a good thing posting them together, however:1) => one should always cut throttle in air, if you only idle at touchdown... you're late basically meaning you're gonna have an over-energetic airplane(see my other reply in the thread about autoland bounces) If you ever see a real plane land that way, either the pilot doesn't know what he's doing or there is something seriously wrong...2) => true, but since that 'indicator' should be synchronised with your joystick(which has ample nullzone to clear possible noise induced effects) at a very high refresh rate, i have zero lag on the indicator .... it's also a good practise to ALWAYS, even on a full autoland, pull your throttle back to it's idle position when the moment of 'retarding'(is this even a verb??) arrives. this also applies to remark 3)3) => see 2) and the heavy impact on the autoland is NORMAL, it's just as simple as that, real world autoland systems(on the 737 anyway, believe me, i've done it in a level D sim(airbus though;), funny actually we also did a GPS coupled landing set the vertical speed to an FPA of -3.00
August 2, 200421 yr Commercial Member Lenny-Thanks for your additional feedback- and the english is better than most. ;-)To further the discussion- it might be helpful if I re-explain (again!) the theory behind the spoiler controller in the PMDG airplane...We had a different system in FS2002- but with the advent of FS9, MSFS made some changes to the spoiler control logic that make it very difficult to work with from a developer standpoint. I won't go into alot of the details there- but suffice to say that it's something we are still pushing via our contacts on the MSFS team to get addressed... (more on that another time.)The manner in which spoilers are modeled in MSFS assumes that the airplane has a single spoiler mechanism that is controlled in full range while in the air or on the ground. (i.e.: You can go from 0-100% in all regimes of flight.)On the 737, however- this is not true. There are some spoilers that will only deploy when the WOW (Weight on Wheels) switch is depressed- and the remainder of the spoiler plates will only deploy through a limited range while in flight.In order to model this in FS2002, we used series of animation sequences within 3DStudio, and then by programmatically limiting the spoiler limits we could animate the spoiler movement from 0 - in-flight limit while in the air..and 0-full while on the ground.Then came FS9......In order to work around the "kludge" that became the FS9 controller- we found that we had to dramatically modify the interaction between the mouse-click, spoiler controller, animation sequences and joystick control. Even after a few hundred hours worth of work we were unable to come up with a desirable result that did not also require a complete rebuild of the airplane animation and center console code....So what we have in the airplane is a "compromise" between our desire to model the system effectively while not completely disabling the MSFS spoiler logic.... From the standpoint of the guy who wrote that section of code- it's my greatest source of annoyance- a bit like accidentally painting a dimple on Mona Lisa.... The key is finding a way to overhaul the code without all the negative side effects. No small task!So best practices for the spoilers are as follows:1) Arm/Disarm using the mouse...2) Make certain that your throttle is well tuned.3) Make sure you are on the idle detent at touchdown unless conditions prohibit.We are designing a spoiler controller for the 747-400 that starts out by taking the MSFS weaknesses into account. Also- because it's design does not include the original work-arounds for FS2002- it isn't nearly as limited in scope as the controller on the NG... So we won't have this problem on the next airplane- and the lessons learned there can be ported back easily- if i do my homework correctly!As always around here- we are always tinkering.... Robert S.

August 2, 200421 yr Lenny,>and the heavy impact on the autoland is NORMAL, it's just as simple as that.Man am I lucky that I fly a 767. The autopilots on this ship grease it on every time.You can really learn a lot by watching the autopilots doing an autoland.>So it's a normal thing that this bird lands a bit more rough than you handfly it to the runway... Sometimes my landings are a tad smoother than the autoland but the autopilots do it much more consistent than I do ;-)RegardsBernt Stolle Capt 767
August 2, 200421 yr hey Bernd not sure as to why that is. Perhaps it has to do with 767 having 3 IRS units to combine for a LAND3 and the 737 only has 2? I don't know, not and aircraft designer I'm afraid :) but I do know the facts... I've heard this comment about autoland from various amounts of pilots, but indeed I must agree none of them were 767 pilots...
