Anyone know of a carburetor heat gauge suitable for FS2K2? Looking for one to drop into a 172 panel.

The default Cessna 172 Skyhawk is not fitted with a carburettor heat control, probably because it has a fuel injected engine.
The Cessna 150/152 aeroplanes are fitted with carburettored engines, and therefore require a heat control to prevent icing in the carburettor.
If you really want a Heat gauge, (remember it's only a push-pull knob), there are many of them in the "Gauges" Folder, but you will need to alter the Aircraft File to suit the new gauge, and find a way of locating a suitable position for the gauge, (using Paint Shop Pro... Wink

....).

P.S. (You will find it difficult to find a space for it in the default Cessna 172 Skylane panel anyway... Wink

You could always put it on a pop-up window. This is easy enough with CfgEdit & a lillte basic knowledge of Panel.cfg. You don't need PSP or any other graphics editor to add or move gauges - unless you wish to edit the BMPs or create new ones.

...why would you want to put a "lillte*" carburettor heat control gauge on a fuel injected Cessna 172 Skyhawk engine...?

I'll grant you that. One up to Fozzer. I'll have my revenge, just you wait. Roll Eyes

My posts are full of typos as I always was a rotten typist. That's why most of them are edited later. You didn't give me time to do this one. Shocked

What's with these "carburettored" engines? I though it was carburated. That didn't take long did it? I can be more pedantic than most people if I wish. LOL Tongue

O.K ...
A truce it is...(for now).... Tongue

...!
On a technical note... 8)...!
I am always surprised that the likes of Lycoming. Continental, et al, still fit carburettors to their aero engines, knowing how vulnerable they are to "icing up" in adverse conditions.
A few years ago we had similar problems with carburettors on certain of our motorcycles for identical reasons (they had to be re-called and fitted with heaters).
Aero carburettors are reasonably cheap and simple, but I'm sure the cost is sometimes outweighed by the dangers.
Fuel injector pump systems are slightly more expensive and complicated. but are infinately more reliable under ~~all~~ most conditions.
Small diesel injected engines are now becoming more common for GA aircraft, and will be the preferred piston engine type in the near future.
(I'm watching them closely)... 8)...!

OK then. This is only a temporary cessation of hostilities you understand. It will last until I feel cheeky again, which could be any time really. Shocked

I'm sure that fuel injection is superior in most ways. Maintenance would be more complicated & thus more expensive of course. Even basic car engines are fitted with fuel injection & electronic ignition these days. The aircraft industry tends to to stick with the old tried & trusted methods.

Okay, okay. Thanks for all the advice.

I think it was Mark Twain who said he wouldn't trust a man who could spell a word only one way.

Relative to the carburetor heat: I'm working on a PPL, and in the 152 and 172, the drill is to add carburetor heat when you reduce power below 2000 rpm (and put on 10 degrees flaps) when you're abeam of the touchdown point. I'd like the heat gauge for more realism.

Carb Heat

Most light aircraft prior to the fuel injected engines being installed on light aircraft used carb heat.

This was normally applied once established on the Downwind leg and prior to turning Base leg.

A drop of 100rpm was not uncommon.

Once established on Final normal use of carb heat was pushed in to cold position increasing rpm and eliminating one more thing to do if an overshoot or missed approach was called forl.

On many light aircraft to-day carb heat is still common along with manual flaps.

There are a lot of articles published on carb heat and icing. I do believe there is information published periodically in Transport Canada's Aviation Safety Letter.

Correct me if I am wrong but I do believe the last Royal Canadian Air Force Dak (DC3 or C47) that was lost operationally was lost on a Search and Rescue Mission and was lost due to Carb. Heat along with the entire crew.

Happy Landings....Cheers....Doug

Hi Hooterg... Grin

...!
I am a great advocate of the use of carburettor heat under adverse conditions..... Wink

...!
Carburettor freezing is the cause of many accidents, often fatal.
I don't know wether you are using FS 2002 or FS 2004, but although you can operate the heat control, FS 2002 is not programed to cause the engine to randomly fail if carb heat is not applied and the carb freezes up... Cry

...!
It can only be set in the "Failures Menu" and unfortunatly the failure is always "timed" to fail... Cry

...!
It is a shame, as the use of carb heat is an important part of safe flying for the learner pilot.
I have set many conditions in FS 2002, where icing is likely to occur, but have never got the engine to fail by NOT applying carb heat when required... Cry

...!
The only affect of its use in the program is to reduce the engine power, indicated by a drop in RPM.

Cheers Hooterg... Grin

...!
Paul.
