GTN 750 : TDS vs PMS

Featured Replies

There had been a couple of threads months ago on this and interesting posts on the Comanche 1.1 thread but  it bears multiple topics now. 

I have a fairly good idea of what a 750 is, had one in P3D, but less on how the two products  compare. I  installed the free PMS version, read the two manuals and watched a couple of You Tube which were very moderately informative. I suppose that very few of you have both but you can see what is possibly missing in yours.

I am now focusing on two specific questions :

1/ How good, complete is the Utilities page,  specially VNAV, Trip Planning, Fuel planning, DALT/TAS Winds  functionalities.

2/ the Data base

The PMS uses Asobo's. It thus has the myriad of airfields the sim has. The TDS Sim uses the Garmin which is supposedly more limited (it was in P3D). 

I installed the standalone Trainer and did a rapid check on two improbable iFR  flights (as often are mine) from Mae Hong Son VTCH  in Thailand to Naypiytaw VYNT in Myanmar, another from WAEE Gebe to Babullah WAEE (great approach btw if you like volcanoes) in Indonesia. Both are in the Garmin trainer with their approach procedures.  But do any of you had an airport missing in the TDS Sim ?

Any other features is, of course, open to discussion (TAWS etc.). I don't own Navigraph so I didn't raise this issue.

The PMS750 site has a large list of "extras" for the premium/lifetime version. It's what I have since I fly everywhere. Never had a missing airport in the PMS750 version.

That is the biggest advantage of the PMS 750 paid version, you get all the airports in MSFS regardless of size, visual approach guidance, great tech support from the developer, and simbrief compatible. https://pms50.com/msfs/downloads/gtn750-premium/

In addition with the PMS you get WTT integration for a very large number of aircraft.

The extras are the normal 750 functionalities which are deactivated in the free version. 

If any of the two would miss an airport that would be the TDS per construction.

I've not come across an airfield yet which isn't there with TDS.

Do you use the calculator functions in the utilities page of the TDS ? Do they work Ok?

The PMS displays MSFS flightplans created on the MSFS Worldmap directly, even without having to save them. The TDS can't do that, you rather have to save and convert them to load them into TDS.

This may not be an issue for most of you creating their flightplans using SimBrief or  which ever external planner, but for me it's quite essential. That's one reason why I only use the PMS (paid) those days, while I own both.

I don't have the PMS50 version, but I know TDS depends on navigation cycle data that is usually old and updated at long intervals. How does PMS50 fair with this issue? I see the site mentions a navigraph subscription.

PMS50 uses the free navdata from the sim or the Navigraph navdata if you use the paid version and have a Navigraph subscription. It also displays the Navigraph charts on the device with the aircraft position on the charts.

If you use Simbrief, it will allow to transfer the plan directly into the TDS FP folder and the same FP will be available in the GPS, so it does work very well, you dont need to convert the plan the Simbrief downloader will do it for you.

I have been using the TDS worldwide since release and have yet to see any airport missing. All functionalities are there and working as advertised. The only drawback compared to the PMS is the Garmin database that is generally behind by at least six months, but since you are not interested by this aspect (you are not a Navigraph user anyway) the TDS is fine and far less expensive than the PMS.

I have both but prefer the PMS for the up to date database.  I recently planned a VFR flight in the USA where a few waypoints on my route were not available in the TDS 750, but all were there in the PMS 750 (planned the flight with Garmin Pilot).

Sure, that's it if you use Simbrief.

However, not everyone does this, and if you just plan your flight on the MSFS World Map, it doesn't transfer to the TDS directly, albeit the plan can be saved and converted to the TDS format (e.g. using Little Navmap, if memory saves me right).

I read a post awhile back on the FS Forum where someone claimed that the current Garmin Trainer data base hadn't been  updated in almost 2 years.

Current data was just updated in the the past month and brings the TDS databases to Dec 2022 dataset which makes them just six months behind. Also I have never had an issue where an airport or named fix was missing.  Approaches maybe, airports never. YMMV,
