    Not so. I have been able to modify the Lear AP code so you can set LinkVor=false and the RXP GTN 750 will work as intended in GPS mode. This in turn frees up both RMI needles to be used independently of the GTN 750.

    As I mentioned above, PM me an email address if you would like to try the modified code.

    Al

    Sorry for the late reply. Been quite busy recently. Definitely interested. Will send email through PM.


  2. Having read a bit around on the RXP GTN forums it appears that LinkVor = true is a requirement for vertical guidance autopilot approach coupling to work. 

    So it appears that the Lear 35 RMI must learn to deal with this and keep both VOR channels open independent of GPS mode or ILS coupling ( the latter only using VOR1 and not blocking VOR2 as well).


  3. Hi,

    using latest GTN 750 in P3D v4.4

    I have the GTN configured to use „simulator“ as clock source. That works fine as to the fact that the GTN will start up with the time set in P3D. 

    However, when using time acceleration, this will have no effect on the elapsed time when using the flight timers within the GTN. The clock speed of the GTN will stay at 1x, which of course gives totally wrong results for time accelerated flights.

    Should the GTN clock speed not adapt to simulator speed when clock source is set to „simulator“ ?

     


  4. Now, as far as I can see, when LinkVor = false, the glide slope *is* there for LPV approaches.

    The problem is that the red vertical GS flags across the sides of ADI and HSI do not clear away. Next to the red flags, on the right side, you can see a tiny yellow arrow tip that moves with vertical guidance in case an LPV approach is active. It appears that the flags obstruct the yellow vertical guidance pointers. You can even see more of the yellow vertical guidance if the deviation is big so the yellow arrows go above or below the red flags.

    See here: https://ibb.co/G7X91FV

     

    However, on arming the GS on the autopilot system, GS will not be captured (presumably because the signal is flagged as invalid).

    Unless there is a setting in the RXP GTN.ini file other than LinkVor=true which kills the VOR indications on the RMI (please share!), I think the Lear ADI/HSI should take away the GS flags and make the autopilot accept the vertical signal as soon as there is any GS input and work properly with LinkVor = false

    Agree something is wrong somewhere. Unfortunately the applicable XML RMI code is in the interior model file which is compiled so I don't have access. However, try setting LinkVor = false in the RXP GTN ini file then save the file and reload the a/c. With that I think the RMI should only respond to VOR/ADF frequencies and be independent of whether the GTN is in the GPS or VLOC mode.

    Al

    Yes, that brings back both(!)  VOR needles on the RMI independent of GPS or VLOC mode.

    But you lose RNAV/LPV vertical guidance 😞. That seems to require VOR linking to be set to true, I just tried it with LPV approaches into LFSB. No glide slope on Lear HSI with VOR linking in GTN disabled.

    Other ideas?


  6. Hi,

    I am using the latest Lear 35 together with a single RXP GTN unit (version 2.5.16.0)

    The GTN, as a single unit, is configured to COM1/NAV1, so my expectation is that it would only occupy the VOR1 channel via GPS.

    I have put the frequency of a nearby VOR in both NAV1 and NAV2 and set both RMI needles to VOR.

    Now, look at this:

    In VLOC mode, both RMI needles indicate the selected VOR, as expected:

    https://ibb.co/W0z9jMV

    Now, the GTN is switched to GPS. Upon doing so, I lose the VOR1 indication on the RMI, since it is now coupled to the GPS. This works as expected:

    https://ibb.co/187jKrp

    Now, I add a waypoint to the flight plan in the GTN. Upon entering the waypoint, VOR2 indication on the RMI is lost:

    https://ibb.co/XLSm0h8

    However, the VOR2 channel should not be affected by the GTN at all, since it is configured to take COM1/NAV1. What is wrong here?

    Thanks for looking into this.

     

     

     

     


  7. I might add that while using IAS hold is the preferred mode in climb, V/S for climbing can be mandated in strong gusty and changing winds. In such conditions, IAS hold mode can lead to huge pitch oscillations resulting in bobbing motions as the aircraft chases IAS. Pretty uncomfortable for pax and pilots alike.


  8. +1 vote for fixing the landing and taxi lights. Really difficult to see taxi lanes and markings on the ground at night, on some payware airports even with only the taxi lights on.

    I tried to tinker around with the lighting based on what I found in the aircraft.cfg, but found that it has no effect. The lighting seems to be compiled into the model.


  9. Hi,

    Please have a look at the following: https://ibb.co/d4dXqwV

    The Lear is tracking the flightplan correctly, but with constant lateral offset.

    This happened on the second leg. First leg from freshly started P3D was without issues, for approach GPS was switched to VLOC to shoot an ILS.

    On turnaround, without restarting P3D, after new flight plan inserted in GTN, GPS guidance was again selected, and flight plan was flown with the observed lateral offset.

     

    GTN is configued to automatically adjust the HSI course.

    Sim is P3D v4.4 on Win 10.

    Any ideas?

    Tired to fly the RNAV/GPS-B at PHMK and GPS-A at Libby, MT (S59)

    Thanks, but on the GPS/RNAV APP. I don't believe there is a freq. to tune.  On an GPS/RNAV APP shouldn't the GPS create a GS on the ADI and the pilots/autopilot follow?

    As I was suspecting, none of the GPS approaches you mentioned has vertical guidance by design. The RNAV part only gives lateral guidance.

    An RNAV approach with vertical guidance requires RNAV/LNAV or RNAV/LPV designations and minima.

    Compare to e. g. the RNAV approach charts for Teterboro (KTEB) which should come up with vertical guidance.

    I believe there was also a photo of a Lear 35 with a GTN 750 installed.

    Lear 35's with GTN are not that uncommon. But interesting to see it was built into a Falcon 50.

    I remember a discussion on our forums a few months back about whether or not it was realistic to equip the DA50 with Garmin GTNs. Only a handful of RW aircraft have had the STC performed, so there's really no pics available on the internet to show the installation. But after some deep browsing of the interwebs (a little bit of link manipulation via guessing) I managed to find this pic from an aircraft that was listed for sale last year. The aircraft has since sold and the photos and listing have been removed, but it turns out the pics are still out there to be found with a little bit of work.

    Small image, but you get the point. Have a look!

    Nice find!

    If only we had GTN crossfill available, it would be the icing on the cake 🙂

    Hi:

    I've attempted two RNAV approaches without success.  The approaches were loaded via the GTN750.  As I approached the 3% glidepath at the intercept altitudes, I armed approach on the autopilot.  But the airplane doesn't follow.  I noticed I got G/S warning flags on the ADI.

    Thanks.

    What was the actual approach you were flying? Not all RNAV approaches have vertical guidance.

    @ark and you are perfectly right! It is a 'who's first' initialization issue with the fuel type prior powering up. We've overlooked this one obviously. Thank you all for your astute help with this! Unfortunately it will have to wait for the next update for a fix.

    Thanks for the information. At least the issue has been identified now.

    Looking forward to the next update!

    I've now also tested the RXP GTN 750 fuel display with the Baron58 as well and the fuel value in pounds is always correct even when the GTN is initially started in the fuel 'pounds' mode.

    So based on the numbers, my hypothesis is that when the GTN starts up in pound fuel units, it defaults to using the weight of AVGAS (about 6 lbs/gallon) instead of the weight of JETA (about 6.7lbs/gallon). Thus the Baron58 numbers are correct, but not the Lear35 or King Air 350 numbers. But if you start the GTN in some other fuel unit besides pounds, when it then switches to pounds it uses the correct lbs/gal value for JETA.

    I posted this on the RXP forum so Jean-Luc can take a look at the issue.

    Al

    Toying a bit more around with this, I realized the same and can confirm your observations.

    Hopefully RXP will look into this.

    I have found that if the GTN750 is started up in the mode with the fuel units in pounds when the FSW Lear35 is loaded, the GTN displays the wrong value. But if the GTN is started up in the mode with the fuel units as gallons, the GTN displays the correct value, and if you then switch the units to pounds, the value will be correct.

    I then tried the default Beech King Air 350 and get the same results. If the GTN750 is initially in the fuel pounds mode when the a/c is loaded, the GTN displays the wrong value.

    The Beech Baron58, which uses AVGAS and not JETA like the Lear35 and King Air 350, did NOT have the above problem -- the GTN displayed the correct fuel weight in pounds.

    So the problem seems to show up when the a/c is using JETA fuel and the GTN is initially (when first started) using pounds for the fuel units.

    I used Win10/P3Dv4.4 for the above tests.

    Al

    Exactly my obervations!


  16. I have experimented further. I get the correct fuel quantity in the GTN if a swap units for fuel quantity within the GTN itself back and forth, e. g. swapping from pounds to kg gives me the correct quantity in kg. Swapping back to lbs then yields the correct weight.

    Unfortunately, that needs to be done every time when the aircraft is loaded.

    Wonder why the GTN can't get it right in the first place when loading up ..

    Thank you for the confirmation.

    When in doubt, it is always best to first remove all plugins/modules/third party aircraft from the equation. It is easier to isolate the causes using a default aircraft too, otherwise there are so many possible points of failure along the entire chain...

    The B58 (XPlane and FltSim) is my favourite test aircraft for the GTN and the GNS V2: simple yet well equipped, fast enough for multiple touch & goes in a short time, light enough to load quick.

     

    Well, I could make the GTN pick up the correct fuel quantity, but with a detour:

    Went into the GTN itself, System setup, units section. 

    Swapped units for fuel from lbs to kg, and lo and behold, I got the correct fuel weight in kilograms. Swapped back to lbs, and finally got the correct fuel weight in lbs.

     

    Sadly, that doesn't stick. I have to do the unit swapping trick every time I load the aircraft for the GTN to pick up the correct fuel weight.
