(PANEL 3) 605 Autopilot / RT859 Transponder / GTN 750 (Requires you own PMS50 GTN750 for MSFS) PMS50 website

Q1. Garmin gauges are Blank NUMBER ONE ISSUE OF ALL TIME Probable Solution:

The GTN750 and GTN750XI both require 3rd party software. 

PMS50 has freeware and payware and TDS has payware at a lower price but it uses the external trainer. So read up on both and try the freeware too. 

Please visit the links above

Q2. I can’t capture an ILS approach or GS Probable Solution:

===Check versions===

Check that all versions of the plane and gauges are up to date and in sync. This is by far the prime cause of ILS problems in this plane if you are capturing them OK while in other planes.

Many users are currently achieving consistent ILS approaches and following the Glide Slope (GS) without any hitches. Therefore we see any known issues are caused by user setups or piloting. 

There are many conditions that have to be met for an ILS to be captured. 

1. Make sure you have the correct ILS frequency dialled into the active NAV radio (NAV1 by default). 
2. Make sure that you switch from GPS to VLOC when you are at Final Approach Fix (FAF). 
3. Check that your angle of approach is narrow, more than 40 degrees either side of the Localiser bearing (check chart) may mean you will not capture the Localiser.
4. Also you should be at the correct Altitude to intercept the Glide Slope (GS). If you are too high you will more than likely fly past at whatever altitude the GPS is currently holding. 
5. Your approach speed may also be a factor. Currently you may need to use a higher speed on descent (100-120Kts) for the GS to be maintained. (This may be addressed in future betas)
6. Also don’t forget to set you baro QNH, this perhaps should have been point 1.

Q3. I have just purchased the 414, how do I install it Probable Solution:


Head to our digital store: 

Then log in and go to orders/history and click the order reference then scroll down. 

There is the registration key and download. The top of this page has instructions on how to locate the download button. Once downloaded unzip the package and inside is an exe installer. Copy your key then run the installer now the key will auto input. 

The installer will do the rest. Once loaded in the sim make sure to look at all the liveries as each 4 have a different panel based on what GPS Gauge panel you plan to use. Also 2 of the panels for the GTN750's require you to have their software.


1) Right click or double click the installation file to start the installer. This installer will auto find your sim no matter where it's located including other drives. If it does not find you sim location contact Flysimware through our websites contact form.

2) Open world map and click the aircraft in the upper left window then click a filter for the type of aircraft and or search for C414AW Chancellor. On the left side you can also click liveries. There are 3 panels and 4 liveries with a total of 12 choices. So click the panel name for the type of GPS you want and then the livery choice. 

3) To use the GTN 750 panels please make sure you read the product page information as this will gives you links to the 3rd party software required for these 2 panels. There is also a file included with links and info. The GNS 530 is included in this package and will work out of the box.

Q4. How do I fix the 10 degrees bug Probable Solution:

The 10 degree bug is caused by the alt capture as far as I can tell. You can temporarily fix the 10 degree bug by disabling alt hold, or if changing altitude, disarming the alt capture. But it'll come back as soon as you turn these modes back on.

Q5. Does the GTN750 manage the ILS (answer by pms50)

The GTN750 is not managing the ILS capture by itself. That can't be on its side if you have an issue.

It also does not manage the flight plan. This is done by the flight planner module (stock or WT).

Just see the GTN750 as an interface between you and the sim.

For example, when you select an approach, the GTN750 requests the sim for the list of approaches, displays it for you to choose from and tells the sim what is the approach index you have selected. Then, the sim updates the flight plan and the GTN750 displays it. Everything works this way.

Q6. Does the GTN select a ILS freq. (answer by pms50)

The GTN750 sets the frequency automatically when you activate an approach that is frequency based (eg ILS) but as the standby one. Up to you to switch it to active frequency.

The stock sim doesn't allow vectors to final. For that you need the premium version. Together with the WT code that is now part of the plane.

With the stock version, select any transition and issue a direct To if you want to bypass some waypoints.

Also, Q. Should I be able to select an approach without a transition?

It seems to always force a transition when selecting one.

Q7. Where can I get the latest information about the pms50 GTN750

Here is a link to their Discord

Q8. Where can I get information/support on the TDS GTNxi

Here is a link to their forums

Q9. What does the WTT GTN mod doNote: From v2.3.0 the WTT mod (patch) is no longer required as WT logic is now incorporated into the Autopilot. From this point on please make sure you remove the pms50 WTT patch. This is important

The WTT (Working Title Technology) replaces the default Asobo autopilot logic and brings more realism. This also allows the PMS50 to have more features. Version 2.3.0 now has a brand new HTML autopilot coded by Flysimware that allows you to assign all buttons to default hardware assignments. And since this also now includes the WT logic for the PMS50 panel you no longer need the package that PMS50 was giving out.

The AP doesn’t do the bizarre things the stock asobo AP does - you can add holds, procedure turns etc. Without the weirdness of the stock flight planner. 

Also it is possible to bind controller keys.

Here is another post from Flying2night

"This 414 is getting to be an absolute JOY to fly. Some flight model tweaks aside, the avionics and AP with the PMS GTN750 (with WTT) are functioning superbly for me.
As a good test, I did the steep ILS RW 09 into EGLC which has burned me too many times in the CJ4, and this 414 coped and exceeded all my expectations. I noticed it even auto switched the CDI from GPS and got me all setup. A (very quick) APR press and the GS armed, then captured right on time, and the steep descent started.
Very happy with that indeed.
Thank you mono and pms50 again. You’re making this aircraft such a joy to fly now."

Q10. How do I get C414 updates



Q11. HOW do I set mixture A. Thanks to @KC Pilot

Entire books have been written on the question "Where do I set the mixture levers?" 😃 
I'll tell you what I do, but know that you'll get different answers from different people. Once you've leveled off and set the power where you want it (I use 30/2300), pull the mixture levers back until you see where the temp on the EGT gauge peaks. Continue pulling back until the temp drops another 50 deg (two marks on the gauge). This will put you at 50 lean-of-peak. Some people prefer to run on the rich side of peak, in which case you would move the mixture levers forward after you reach peak, instead of continuing to pull back. 

More help on Mixture leaning (Thanks to @Riggo_RNV)

With Manifold at 32-33 and rpm at around 2400-2500 you can lean the plane to around 115lb/h per engine

In climb you can go for Manifold 35, RPM 2500 and lean to around 155lb/h 

Q12. Why does my plane drop it’s nose when I turn on the Autopilot to climb. (PCT Switch)

The PCT (pitch) Switch on yoke is used to Set Pitch. When setting up for a climb, before turning on the Autopilot, trim the plane to the desired pitch. Also make sure Gear and Flaps are up. Now press the PCT button then engage the A/P. Note. The A/P should have already been set up in preparation, even on the ground prior to takeoff.

This way you will not get a drop of the nose before the A/P gets a chance to correct the pitch. 

Here is a more detailed note from mono…

First turn on the FD and the YD before takeoff. Then once you takeoff and pitch up your are supposed to use the PCT switch on the pilots yoke right side and this syncs the FD to the pitch you are at so when you enable the autopilot the PID mode which is the pitch mode will be synced and will maintain that pitch. Right now the FD is at zero and actually about -4 degrees since this plane sits nose up when level on ground. Or you can turn on VS and pitch the wheel making the FD pitch up to your current VSI and then turn on AP and it will maintain with no nose down issue. 

Q13. How to start up and set up the Autopilot for a VFR flightPlease Note: Since the release of 2.3.0, the steps involved in setting up the Autopilot have changed. I will produce a new video shortly.

I have produced this short Video in an effort to help.

An 11 minute video on starting up the Flysimware C414AW and a short VFR flight to demonstrate the use of the Autopilot. I'm using the latest beta 2.2.0 with the pms50GTN as well as their WTT patch. I'm not a very polished content maker but wanted to try to help those who are finding it hard to set up the Autopilot in particular. This is offered warts and all. One being at 04:15 where I referred to the ALT button as the Alternator, meant to say Altitude.

Q14. What do I do if I see my power or EGT drop a lot Thanks to WxMArc

If you are seeing a drop in EGT and loss of engine power at altitude: 

1. Check your power setting. Are you running for a long time at full power? The engine config file specifies that detonation can occur above 39 inches manifold pressure. If you are operating for long periods at full power (41 inches), you can damage the engine. This will show up as a gradual loss in power, dropping fuel flow and EGT. Normal climb power is 35 MP and 2500 RPM.

2. If you are not running the engines at extreme power settings, are you using any third-party software to map your hardware buttons and levers to sim events? If so, ensure that any mixture settings are mapped to the AXIS MIXTURE1 SET and AXIS MIXTURE2 SET events.

I suspect that toggling the assistance settings resets the engine damage variables. That's why the engines work properly again after switching assistance presets.

Q15. Why are the C414AW’s props bent at the tips

They are a design type to improve aerodynamics, just like winglets on wings. 

Q16. How can I prevent my plane from bobbing up and down on Autopilot (porpoising) (Thanks to Poundy) NOTE: This has been fixed in beta ver 2.3.0

This is autopilot related not related to the GPS module you choose. For the moment there are files to help, it might make it less noticeable, but some people have reported things working worse not better. Give them a try first or wait for the next beta release.

Q17. Will I still need the WTT mod with the pms50 GTN 750 once I have beta v2.3.0

Please note that the PMS50 GTN 750 now includes the WTT logic with out our new HTML autopilot. So there is no need to download any WTT patches from PMS50.

Since 2.3.0 we have dedicated default liveries for the pms50 GTN750 with and without WTT. Select the appropriate livery"
