I don’t use the cockpit UI to enable de-icing… I just have a switch on my throttle that I link to all the de-icing key binds. Engine de-icing, prop, pilot heating, wings etc. with a single switch.
This way I can fly any aircraft and throw that switch on, and not be bothered about the location of de-icing options in the specific aircraft. 
But that said I’m very curious as to where the de-icing switches are on the c172 skyhawk. Does this thing not have de-icing ?
As I just wrote a couple of posts ago: some planes are not made for icing conditions. The 172 is not to be flown in icing conditions because it has no de icing. It has pitot heat and cabin heat. That’s it.

So what do you know you can fly the c172 at 0C and still be fine 
So the only thing that was being enabled by me throwing the “de-icing” switch on my throttle was actually pilot heating and cabin heating
I have a question… Is there some mechanism on the c172 that tells you how far you can fly with the amount of fuel left maintaining the current speed ?
E6B, and some basic math

I take it beyond the basic math, there is no system that calculates it for you… Hmm what a shame.
Update: Yes it can be found Page 157, 158, 159 of the g1000 manual (The fuel range ring). What an amazing piece of computer the g1000

Update: Unfortunately that feature isn’t part of the Sim however 
Should ask Asobo to add this feature in.

As a casual player, I don’t even know that feature exists IRL.
Would be awesome if Working Title’s G1000 mod could eventual include this.
Are you telling me that, the linked Github repo is the source for the g1000 system in-game ?
Super cool, its an interesting project.
It’s all Javscript, with most of the visual stuff build using SVG.
If that’s true the entire g1000 cockpit is a browser runtime
You wouldn’t be able to use the mod during the Cannonball Run Challenge though.
The DA40NG does not have a useful range of 940nm as the extended tank is not implemented in the game.
why not? It’s not modifying performance. I am still flying the default 172G1000; no custom livery or flight model enhancement per the rules. Only the G1000 unit navigation is modified.
I need a rule clarification on Rule 1 and Rule 7. Given that Rule 7 gives a save point and Rule 1 requires 10 min for repositioning / refueling. Is it acceptable to land leave game and continue on from the last “save point” as long as you don’t do it under 10 mins? The reason I ask this is, if minor icing forces a landing at an airport, it would be a way to simulate ground deicing.
If it has more functionality than the stock version, I‘d say it’s modifying performance. But I am not making the rules here.
Yes it’s not fair being able to use external mods, as it wouldn’t be fair. I agree.

Yeah, that’s fine. After you land and create a “save point”, you can end your active session, close MSFS, relaunch the sim, do whatever you want. You just can’t take off again after adding more fuel until a minimum of 10 minutes of real-time have passed.
Important clarification: when we land for re-fueling, we have to refuel, and THEN count 10 mins, or can I count 10 mins and refuel right before TO?
Once you land, and have come to a full stop you must engage your hand break. At this point your 10 min timer starts. During which time you can use the in-game menu to refuel and your allowed to take off when the 10 min expires. However if you take off say 15 seconds early, that will be reduced from your time pool at the end.

I think it was decided that after you come to a complete stop you are allowed to taxi @ < 50kts if you want to reposition your aircraft to the approach end of the runway or actually taxi to the fuel box.

That’s right. You are allowed to do whatever you like in that 10 mins as long as you stay below 50knts. You can visit the fueling station if you prefer that to using the in-game menu to fuel.
Personally this is what I plan on doing. Exit the game and restart it. Load up the new plan file and check if it’s still optimal based on wind and enter the last landed airport.
The only reason I plan to close the game and restart it is because when you do really long hour flights there is some kind of memory leak happening. That can in the end result in a game crash. So killing the app between each leg would keep things light and more stable.

Updated the OP with clarification of what difficulty settings must be enabled in the Options menu:
Full realism settings in MSFS must be enabled. In the Options Menu, “Piloting” must be set to “Hard” with the exception of “Take-off Auto Rudder” which can be on or off depending on your preference. “Aircraft Systems” and “Failure & Damage” must be set to “Hard”. All “Navigation Aids” must be turned off with the exception of “Taxi Ribbon” which can be on or off depending on your preference.
