Carbon Cub's new features help!

[Jucasim]

Hello Folks!

 

I´m wondering if somebody has any tips on how to use the new Carbon Cub radio, gps, the "rpm panel sticker" :P, mixture control and specially (in my case) the proper use of the "carb. heat"! Do all of the knobs in the digital gps/radio work?

 

Oh, and i know that there are lots of tutorials in the web, and even in the "avsim" forum. But i´m looking for specific details and tips on how to make the most out of the new Carbon Cub!

 

-------------------------

Keep on flying!

I'll put together a "Cub Panel" write-up for the Tutorials section like I did for the Maule and RV-6 soon. I need to do ones for the Icon and Stearman anyway... just never got around to it.

I am actually hoping that some enterprising soul with time on their hands does a pictorial or video presentation on the radios one day. with some actual in-game examples. I don't think my little head is getting the finer points just from typed instruction.

 

Maybe an instructor group, one day, on the Mic.

 

EDIT: Seems I posted a second late!

The checklist `Q` helps a lot.

 

Mixture should be set to 60% for max power at sea level, less if you go higher. You can figure it out by watching the RPM indicator.

I think Carb Heat is not necessary as we don`t have icing conditions simulated up to now. If you want it , read the checklist when to activate (take-off/landing especially)

 

Not all knobs work. At the radio the ENT and SYS don`t work, but all the others.

GPS is the same like Icon.

Transponder just for on/off/stdby, cursor, clear, numbers, VFR.

Carb ice can happen in hot summer days, and it kills people most of the time when they didn't even thought it was possible...

[Heimi]

Icing conditions have nothing to do with summer or winter, it can happen anytime.

Has to do with airflow in the carb. which is not simulated in Flight.

That would be great RoboRay! That would make the game even more interesting to a lot of simmers! Thanks

Really cool idea!

Wow! Quick and precise! That will help me toy around the plane, and make it fly well, until i understand why i have to do that...maybe on RoboRay´s tutorial! :lol:

 

THANKS A LOT GUYS!

Carb heat ON when you reduce power to descend. Carb heat on when you're on the ground and there's evidence of carb icing. Carb heat OFF for takeoff and climb. Only on for cruise when there's icing. You know there's icing because yo gradually lose power.

 

Generally, ice doesn't form in the carb under high power. It may form during cruise. It can easily form at idle or during taxi when conditions are right.

 

Durng runup you pull carb heat on to make sure it's working. Note that carb heat is always full on or full off, because partial carb heat can melt small ice crystals that would normally not be a problem, which will then refreeze on the carb itself.

Humm...unfortunately i guess that is how some technology advances...

I was never really sure if temperature was simulated in MS Flight...i have read in a post that we could measure it looking at the oil or engine temp. gauges with the airplane parked before a mission...i don´t know if it has any real effect during flight...

 

Did you notice any effect using the carb. heat in the Cub? (at least close to the real effect)

[Heimi]

To be precise a quote from the manual:

 

Carburetor ice may form in temperatures from 32° to 100°F when the relative humidity is greater than 50%. Be

alert for this condition if flying when the difference between the temperature and dew point is less than 20°or when there is visible moisture in the air. If carburetor icing is suspected of causing a loss in power, apply full carburetor heat. If the engine operation remains rough,adjust the mixture control to obtain maximum smoothness. Leave the throttle setting the same and wait for the engine to run smoothly once again after the ice is cleared. If there is no improvement, gradually apply full throttle and initiate a maximum rate climb to produce as much heat as possible under the cowling.

If the engine continues to run rough, it may indicate that ice is accumulating on the propeller.

It is also good practice to apply carburetor heat prior to

and during an extended descent as a preventive measure.

 

In MSFlight temperature effects are not simulated.

But using Carb Heat drops the RPM of the Cub.

So can i say that it works like an "pitot heat" for the engine...avoiding the ice to block the carburetor airflow or something like that?

Yes, but rememeber the carburetor has a special set of circumstances that lead to ice formation even if the pitot never gets frozen. Air goes through, is slightly compressed, then decompressed rapidly which results in a refrigeraton effect. Also, the evaporating fuel in the same spot causes a temperature decrease as well.

 

This is why carb heat comes on every time you decrease power. The carb can start freezing for no apparent good reason even when the weather is hot.

The icing is also exacerbated by the closed throttle plate which causes the pressure change in the carb throat. ( if I remember correctly) .

[LHookins]

the closed throttle plate

 

Good catch. With the throttle anywhere but full open, the "manifold pressure" is actually a vacuum. Reducing the pressure reduces the temperature.

exactly! it used to be modeled in fs9, previous versions of xplane modeled it to the extreme, and I really don't think it is "activated" in ms flight... This is a limitation I never understood very well in flight simulators for aspirated engines, given it's importance...
