RNAV approach using LNAV/VNAV
Litjan replied to tango4's topic in 737-300 Aircraft Systems and Operation
Ok, this certainly does not sound like the cases I described - they would all have the LOC deviation pointer centered. I could also imagine a strong shift in winds - the gain (how hard the AP tries to track the LOC) is reduced when closer to the ground - otherwise the AP would get too twitchy and hectic. This is analog to the real aircraft, and a reason why automatic approaches are limited to 10kts of crosswind. There is also the need for the Pilot Monitoring to watch the deviation scales and call for a go-around if deviation exceeds 1/4 dot LOC or 1/2 dot GS (iirc), because this exact same think can happen with shifting winds in real life. If it happens to you again, try to capture a screenshot (with the FMA showing), or possibly even a short movie (I am using ShadowPlay so I can capture the "last two minutes" with a press of a button). Thanks again, Jan -
RNAV approach using LNAV/VNAV
Litjan replied to tango4's topic in 737-300 Aircraft Systems and Operation
Hi Charles, again, thanks for the feedback, both positive and constructive ;-) We are very aware of our shortcomings - and although it has been a bit more "quiet" on the update front in the last few weeks, we are at work on the the first big comprehensive update (no ETA yet). I expect to scratch quite a few items off the "not in 1.0" list for that, and you may have seen a teaser shot of the new TCAS, for example. The problem with the LOC signal not leading you down to the centerline can probably be attributed to (95%) bad X-Plane navigational data - usually the runway is misplaced by a bit. Go to your local map and zoom in on the runway (with display of ILS´s selected), then you can see how well the LOC lines up with the runway. The remaining 5% are attributed to deliberately offset LOC approaches (like KFLG, for example). Happy landings, Jan -
RNAV approach using LNAV/VNAV
Litjan replied to tango4's topic in 737-300 Aircraft Systems and Operation
Hi Charles, First, thanks for the nice words in your initial post. And yes, there is still lots to do on this aircraft, and we are well aware and working on it ;-) you are correct - the 737-300 is not certified for LNAV/VNAV approaches (to my knowledge) - you have to fly the RNAV in LNAV and V/S, using the deviation bar like a "glideslope". At least that´s how we did it when I still flew the 737. Cheers, Jan -
So far every single instance of this happening could be traced to a "live virus scanner" type software that is interfering with the in-out database accessing that is running while the route is in a MOD state. I am a bit surprised by rgeber´s report because he specificially states that he has no anti-virus running...But that was the only report of that kind we ever got. Cheers, Jan

Huh, that is strange - we are forcing the switchover once past a certain altitude - so I wonder what happend. Thanks for the report, we will try to recreate (and fix) this! Cheers, Jan

Hi Pierre, we are experiencing some difficulties with this in 1.0.7 - so what you are seeing is under investigation! Thanks for the report, Jan

The DH should always be set to the same value - after all it is just one aircraft doing one approach that only has one DH . The DH is only used for CAT II and CAT IIIa approaches - so they should be set to the value specified in the approach charts for CAT II (usually around 100) or to 50´ for CAT IIIa autoland approaches. For all other approaches, set both to -20. Jan

basic tutorial to get wing view / passenger cabin view
Litjan replied to cmbaviator's topic in General Discussion
Hit the "W" key... Jan -
Yes, this will work if the angle is not too large - the plane will adjust for the drift. But if the set course is grossly wrong, the plane will turn "off" the localizer signal and then have no way of recapturing the centerline. Jan

Hi, As far as I know and remember, the wing-anti-ice valve is always closed on the ground - it only opens in the GRD TST position, but only until the thermal switch triggers and closes it. This is the way it was on the Classics I flew and the way we modeled it - no plans to change that, even if there are other configurations for the Classic. The Classic has no automatic increase of N1 during engine or wing-anti-ice bleed extraction. Bleed supply is always sufficient to provide anti-icing, even at idle. The ram door operation is not described very well in the manuals - it is completely independent and can not be influenced by the pilots. It says "at slow speeds", but there is no speed specified, so we only modeled the "flaps not up" - as that pretty much covers the slow speeds as well. Cheers, Jan

Ah, ok . The waypoints where full latitudes cross full longitudes are available in the nav-database... The format is like N5150 or 51N50 and so on. The placement of the N determines wether its 50 West or East. I am not totally sure of the correct syntax, but if you boot up and place yourself at BGBW you should be able to take a look at the local map and see those points. Then you can figure it out. Jan

Yes, known problem. Don´t select a runway without an instrument approach for now to avoid that. Cheers, Jan PS: The FMS can´t take stuff like M074F360 - this is not entered into the route, normally, it is just information for ATC when filing the flightplan. Also NATF is not determined - the NAT tracks will be determined and issued by Shanwick Oceanic twice a day - so NATF will be different from day to day. You have to enter the waypoints of NAT F point by point. Jan

Thanks for the report - I have added it to the list of things to be fixed! Jan -
error 1142: attempt to index upvalue 'crd' (a nil value)
Litjan replied to dvasi's topic in Bug Reports
Hi and thanks for the logs - we are adding it to our list of quirks to look in to. Jan -
There is a non-normal checklist for this, it used to be called "loss of both engine driven generators" iirc. Jan

Well, it is noticeable that you will rarely hear anything rude from a controller here in Europe or anywhere where the airlines are paying for the ATC service directly and per flight. Testy in more stressful situations (when they have to call someone 5 times because they aren´t listening properly), but never downright rude. The U.S., where ATC is paid by for the goverment is a whole different story. Efficient,yes. Likeable, mostly - but dare to ask the JFK approach controller to repeat his clearance Now if you employ a "real" controller to work on a service like PilotEdge, I would think it a testimony to the realism of the whole setup if the guy forgets that its "just a game" and takes it all seriously enough to fall back into old habits when dealing with non-compliant aircraft. Nice? Maybe not. Realistic? Definitely. Don´t forget that part of the whole ATC experience is also the pressure to not mess up, play along and to not be the clog in the wheel of a nicely humming EGLL approach flow... Jan

Yeah, I love it when manuals are clear and concise and leave no room for misinterpretation. Here is my favourite one: Quote: There appears to be some confusion over the new pilot role titles. This notice will hopefully clear up any misunderstandings. The titles P1, P2, and Co-Pilot will now cease to have any meaning, within the BA operations manuals. They are to be replaced by Handling Pilot, Non-handling Pilot, Handling Landing Pilot, Non-Handling Landing Pilot, Handling Non-Landing Pilot, and Non Handling Non-Landing Pilot. The Landing Pilot, is initially the Handling Pilot and will handle the take-off and landing except in role reversal when he is the Non-Handling Pilot for taxi until the Handling Non-Landing Pilot, hands the handling to the Landing Pilot at eighty knots. The Non-Landing (Non-Handling, since the Landing Pilot is handling) Pilot reads the checklist to the Handling Pilot until after Before Descent Checklist completion, when the Handling Landing Pilot hands the handling to the Non-Handling Non-Landing Pilot who then becomes the Handling Non-Landing Pilot. The Landing Pilot is the Non-Handling Pilot until the "decision altitude" call, when the Handling Non-Landing Pilot hands the handling to the Non-Handling Landing Pilot, unless the latter calls "go-around", in which case the Handling Non-Landing Pilot, continues Handling and the Non-Handling Landing Pilot continues non-handling until the next call of "land" or "go-around", as appropriate. In view of the recent confusion over these rules, it was deemed necessary to restate them clearly."

Main panel and fuel gauges problems X-plane 10.50b5 1.0.7
Litjan replied to MartyJazz's topic in Bug Reports
Thanks for the follow-ups, everyone! Jan -
Yeah, the plane will fly perfectly fine without any electrical power - as long as you are in VMC. So there is always that element of luck involved when these (rare) events take place. Jan
-
What, only one busload of worshippers??
-
Yeah, you are right - I parked the plane as well... Actually, I do fly it on warm summer days (not too high!) and cold winter days . We are aware and will fix (probably some X-Plane dataref thingy again...) Thanks for the report, Jean! Jan

Hi, it is modeled - but right now it can not be seen because the 5th stage has been beefed up by us to provide more air during testing prior to release. It turned out that our model was not able to maintain cabin pressure running on only one engine at higher altitudes - before the 9th stage would open, the volume got too low. We could have tuned to make the 9th stage open at a higher PSI level - but this didn´t work according to the videos I made from the real plane, so as a stopgap measure we simple increased 5th stage pressure output. We may tune this at a later stage. In the real airplane you can sometimes feel it getting suddently warmer in the cabin during descents - the 9th stage opens, and the bleed air is considerably warmer than from the 5th stage. So before the AC system gets a chance to react, it first gets noticeably warmer... Jan

Tony is right - and so is his fiancee (give her a kiss for me, will ya?) My brother is complaining that he only got two stripes, though - oh well, if he shapes up a bit with his flying, who knows, maybe a rank progression is going to come his way? If he could only stop looking around the cockpit and concentrate... Jan

Hi, runways can not be added (also not on the real one, afaik), AC is a DME station and can also not be shown. RB would be possible, though. Cheers, Jan

Hmm, so we have two people reporting this, both running Radeon Chips on iMacs, running 10.11 OSX... Nils did try to put in a protection into the OpenGL code that MIGHT help with this - probably showing in 1.0.8 or more likely 1.1. Let me know if there is anything else you can figure out - I will be working on plans for the shrine just in case this works out . Jan
