Hijacking the thread......Do you need the 510 with a 750xi? I know you do for the 750.

I have to ask because I have never done this nor really understand the benefit. But for the purpose of "planning" the flight the night before, do people actually plan for anything other than Origin DIRECT destination? And if you are filing IFR< the clearance will almost always be different than your filed route unless you're out in the middle of nowhere going direct A to B. So the planning you did the night before is worthless now because the clearance would be different.

FF gives you the option to update your flight plan with the new routing. Then you BLuetooth it to your Nav system.

A 15-second online Garmin search for that question shows that the 510 would be required for the Xi. Good to know because the topic GPS 175 has Connext® cockpit connectivity built in.

Out here in California, high mountain terrain, class B, and restricted airspace are the most common reasons I never go direct from a point A to point B and therefore have to do some advanced planning.

I'm a big fan of fltplan.com which was bought by Garmin. In that app (and maybe others) are the last bunch of filed routes for a trip. I prefer to study the routes to get an idea of the arrivals and waypoints and names and altitudes so there are no surprises.

If you file one of those previous routes, there is an excellent chance of getting it.

The other benefit is when you get "cleared to" some weird name, it will be in your flight plan already or at least you will have seen it. Sometimes there are clearance points not on a map but only on an approach plate. Knowing those points and not sounding like a dunce is a big win in congested airspace.

In this example below is a IFR route request Dallas(Addison) to Las Vegas. Check the routing and the type of aircraft cleared and you probably will figure out what to expect, have it already loaded in and only make minor changes during the taxi or flight. If it was on your mobile device it can be sent by Connext to the GPS 175, for example, as listed in this topic.

The best part is you can study those departures and names amd load it into your ipad and not sound like a dunce when it comes through.

The laziest method is to get your clearance on fltplan.com sent to your mobile device when your flight plan is received by the FAA and entered into the system. You will know at least an hour ahead what you are going to get as a clearance. You will have time to study, make changes or delay times etc.

There is no reason today to get any surprises on clearances.

Be careful using those route as in most cases they are planned routes only. I can put all kinds of weird routes in there that make zero sense and will then show up as a "planned" route.

Dude, those are actual clearances provided by ATC at departure. I only have 10 years of using them. How many times have you used them and they were wrong on fltplan.com? Do you have an example from your logbooks and flight plans you can provide us?

Is the 175 depending on a terrain/obstacle warning to avoid hitting something? I'm curious about what this statement really means. How does the 175 visual approach feature take "into consideration terrain and obstacle avoidance"?

Following

Yes. among other things, check the status of MOA's and flight plan around the active ones.

Definitely use the common sense filter when using "previously approved routes" on any app. I got a suggested route from KDTN to KSPS that recommended I fly just south of Tulsa which is 150NMish north of my route.

I hope all this chatter helps get the 175 sold. I really like the unit, but I am not sure what I'd do with one in my panel.

I have a GPS 175 in my plane. It was a great affordable upgrade to my avionics. I debated a used 430 but quickly came to the realization the 175 is a better choice. What i like about it is the software is very intuitive and has the Bluetooth capabilities. It not only accepts the waypoint info from Foreflight it can push it to an ipad. If i enter a clearance route on the 175’s flight plan page of the unit, it can push it to the foreflight to have the same flight plan info on my moving map. This works better for me as airways can just be entry and exit on the 175 and all the waypoints are populated to a foreflight flight plan. Simple

For the cost of the unit it is a great addition to any non gps panel. Touch screen, modern software and will be supported for many years.
