    Okay so how much experience do you have with PT6A engines with prop aimed directly at the cockpit?   I mean, you state there is not a lot specific, that indicates at least some solid experience with how other aircraft, with that engine,  sound in the cockpit.  You might not agree but you do so while stating that you have zero experience. 

     

    For now this is the sound set we have and there are no immediate plans to update it.

    That's too bad that you've just decided to give up on this after a year's work.  This is the most requested update for the Twotter, you asked for feedback, and now you're arbitrarily shutting it down because you won't consider reasonable feedback from a person who understands the scientific principles that explain how an aircraft generates noise. 

     

    So what if I had just made a new account, told you that I am an astronaut and DHC factory test pilot who flew the DHC-6 on its first flight, wrote the same post, you would have accepted the same feedback?  Do you see what I'm saying?

    Do you have actual experience on the aircraft? It is very specific in it's sounds.

    No.  But I do not agree that a Twin Otter is "very specific" in it's sound.  I explained my qualifications in my post.  Is is a twin engine, PT6A powered turboprop, with 3-blade propellers.  It is unpressurized and minimally insulated so it is loud inside.  There is nothing I can not grasp about that.

     

    Hopefully you can at least agree with my simple observations such as the pitch of the prop sound should not be different inside than outside...it's scientific principle.  And there should be wind sound in the cockpit.

  3. I think this is great!  This is the meaty update that people have been waiting a year for!  After the Twotter was first released, I tediously developed a legacy FSX-style sound pack for myself while my family was sick with COVID.  I spent more time on that item than I would ever imagine I could spend on FS, but FINALLY I am happy to say I no longer need it.

     

    I don't completely agree with the way you are choosing to qualify user feedback.....however I will offer the following: I have not been able to fly or fly in a twotter despite my best efforts (we planned a holiday in the Caribbean that included a segment on Winair...pandemic again) but I am a freelance corporate jet pilot IRL, but I have also flown King Air series, MU-2, Tucano T.1 and been a passenger in various turboprops.

     

    -The pitch of propeller sounds is not matched between interior & exterior.   The interior sounds are lower pitch than exterior, but the EXterior pitch sounds more correct to me...except at 76% NP where I think both need to be slightly lower pitch.

     

    -Transitions in/out of feather are not smooth.  OUT of feather is the least graceful.  The "flop-flop-flop" sound of a feathered propeller is proportional to RPM, as is any propeller-produced sound.  When you hear a prop unfeathering, the "flop-flop" speeds up and cross-fades with a pitch range where it is briefly pretty quiet, before reaching the idle speed.

     

    -Turbine sounds could be about 15% lower during flight.  Prop sound should be strongly dominant in flight.

     

    -There is no wind sound that I can perceive.  Twotter is unpressurized, minimally insulated, with big car doors in the and sliding windows in the cockpit.  There should definitely be wind sound in the cockpit.

     

    -Beta-reverse sounds could be run through a low-pass filter.  The hissing quality of those samples hides the realistic reverse sounds.  Otherwise a good improvement.

     

    -NP=76% sounds are not quite phase-synced...close but not exact.  If I had a 6-lever throttle device, it wouldn't matter (I could sync props manually) but unfortunately I & many others don't.  Creates a bit of ear fatigue during cruise for headphone users.

  4. OK, it's happened again.

    A319 CFM on 1.2.3.2.  Windows 7 Pro.  i7-4790K @ 4.5 ghz.  GTX1080ti.  32GB DDR3.  ChasePlane, ActiveSky ASP4 with REX SkyForce (injecting clouds only), running in the background as usual. 

     

    Flight plan:  KLAS BOACH8.RIKII SHTNR.ANJLL4 KLAX FL280

     

    Loaded the flight, set cold/dark state as usual.  Used the fuel planner and the INIT LOADSHEET feature on the 3rd FMS, which I don't normally.  Flew the whole flight in managed mode without any modifications to the route (until the end anyway...decided to change the approach after speed went haywire).  Made a manual descent with V/S from FL280-260, and then again to 240.  Engaged managed DES prior to GLESN (has a window constraint FL240-300).  Managed speed worked fine until GLESN at which point it dropped to around green dot speed.  I also noticed something else strange...overhead GLESN and next two (I think) waypoints, the footrests on both sides of the cockpit extended and then retracted spontaneously.  I realize that those animate on their own when the aircraft enters the CRZ phase, so I thought it was worth noting.  They just extended and retracted on their own at the instant I passed GLESN, ANJLL, and CAANN.

     

    I can test again, perhaps tomorrow night...but the last time I ran into this bug (see my post from a few days ago) was also in the A319 after passing a waypoint that had one of these window constraints (i.e. as above, cross GLESN between FL240-300 and 280KIAS).  I don't know if that is a common feature of procedures in Europe, but they are quite common on RNAV STARs in the U.S.

     

    Logs attached.

    @fedenav I am  following this topic for a couple of days. I've experienced the same bug with my A319, flying from Hamburg to Stockholm. I remember that I've also changed my arriving runway. This was the only flight with this issue and also the only flight, I was changing the runway during cruise/descent. All my other flights (could be about 10-15 flights) since the update were normal, but I didn't changed the runway there. I use Active Sky for P3D V4 and usually the wind-prediction seems to be correct. So changing the runway during flight was not necessary for the other flights, because I set the correct arrival-runway before departure.

    This could be indeed a hot tip.

     

    Best regards

    Your idea makes sense, but I experienced the issue on 1.2.3.0 even when flying the route as initially loaded without any modifications.  I have also changed the landing runway or the approach or the entire STAR + runway with no issue.

  6. Just upgraded to 1.2.3.2 last night.  Two flights today...no issues on the first one, this happened on the second one.

    A319 IAE

    KLAS BOACH8.LVELL.LUCK1.KSAN FL260

     

    Flying LUCKI1 STAR to KSAN.  LVELL transition was loaded however I proceeded direct MOMAR.  Prior to TOD, I selected the LOC27 approach to KSAN, no approach was selected prior to that.

     

    10 mi prior to MOMAR I selected 12,000', 2 mi prior to MOMAR I armed DES.  MOMAR has a window constraint FL240-260, no speed restriction.  The initial step down to MOMAR was fine, however during the level-off for the constraint at MOMAR, managed speed reset to 214 KIAS, even though there was a 270KT constraint ahead.  I tried to go back into managed speed a few fixes down the road, but it was still commanding something around min speed.

     

    Logs attached.  I paused and copied the logs as soon as I noticed the problem.

    I've had the whole A318-321 Pro package since Thursday... I've done maybe a dozen flights (used all the models), and I can tell you that the only times managed speed has provided sensible values at all were my 1) very first flight and 2) my most recent flight.  The common thread between those flights is that I did not set the weight units to LBS, as would be my preference.

     

    The issue I have with managed speed is that it gets stuck on an arbitrary low IAS, usually a few knots above minimum speed.  Managed descent also fails to capture the VNAV path.  I know how to operate the FMGC and A/P...the minimum entries required to fly this add-on are pretty straight-forward. 

     

    Perhaps we can investigate the LBS/KGs thing?

     

    It’s too late to edit my post, but this is not the problem.  I have made three more flights without issue.  I am following this regimen strictly:

     

    -Do not use implied entries in MCDU preflight.  i.e. if block fuel is 15,000 lbs, type “15.0” not “15”.

     

    -Ensure all fields are filled on INIT and PERF and a departure runway selected in FPLAN (you do this anyway to get the FMC-calculated speeds)

     

    -Ensure Managed CLB is selected prior to T/O (press the ALT knob IN, V/S window shows “————— “) 

     

    I realize that #2 & 3 are things you should be doing anyway, so don’t laugh me out...it just seems like we need to be methodical to get to the bottom of this bug, and I’m not sure how many people reporting the issue could be classified as casual vs. serious flyers.

     

    V1.2.3.0.  Also, I use ActiveSky (ASP4 & ASCA) on every flight...some people had mentioned that above as a suspect.
