Hey everyone... I'm having a bit of trouble with the CAP Search mission (with the Maule). After I pass the first checkpoint (at which I am at 7,000 feet), I turn onto the first search leg and begin climbing to a higher altitude. My problem is that I keep losing power at about 7200-7300... and I can never get higher than that. I suspect icing but I havent been able to figure out how to prevent it. Anyone know?

doh!! Didn't read the last part of your post, sorry.Keyword: Carb HeatCarb heat is applied in Maule by clicking the T-handle just above the electrical switches. Or.....just hit 'H' on the keyboard.Regards,Cal

Hmmm, considering the Maule doesn't have a carburetor I don't think that's it. ;)It sounds like the mixture is too rich. Press CTRL+SHIFT+F2 a few times. (Or you can turn on auto-mixture in the realism settings.)

Thanks for the input... but I dont think it is fuel because I've checked that (I'm a real-world pilot so fuel is something I usually check after loss of power). I tried adjusting mixture even WITH auto-mixture on, and I also tried alternate air, knowing that there is no carb in the Maule. I'll give it another shot and try a few more things. Thanks again.

I've had it myself, it is engine / carb icing, which is a challenge since the Maule doesn't have engine de-ice or Carb Heat knobs on the panel, but the H (Carb Heat) key does work and does solve the power problem.I've tested it several times in the mission, if you climb high enough into the clouds it happens every time, and has absolutely nothing to do with mixture. Every time hitting the carb heat key solves it.You'll also pick up ice on the aircraft too so turn on the pitot heat so the airspeed still works and limit time above 7000.

Actually I just tried alternate air again... it worked this time.There is no engine/carb icing... it is induction icing (if I remember my terms right). Alternate air bypasses the intake air because it is blocked by ice, hence the power loss. I finished the mission... very cool mission. I am really enjoying all the missions and I can see enormous potential for user missions!

Hi all,Check this out: (especially the part about the available engines)http://www.mauleairinc.com/Our_Planes/Maul...b_and_235c.htmlRegards,Cal

It would seem there are two versions of Maule "Orion", one with a 235hp engine (both injected and NOT) and another Orion with a 260-hp injected engine. According to the data in FSX, it's the latter. Is it possible somebody did a little cross-breeding here so that carb ice is possible?Cal

No cross breeding... like I said, fuel-injected engines CAN have icing problems, but just a different sort. Again, I believe I was experiencing induction icing, and turning on alternate air enabled me to draw air from an alternate source because my intakes were blocked up with ice.Mike (or any ACES member), hopefully you are reading this because I just now discovered why Alternate air didnt work for me the first time. I cycled through the cockpit views until it showed me the closeup of the throttle/prop/mixture area, where the alternate air pull is located. The cockpit tooltips labeled the alternate air as "Alternate Static Source" so I believe there was a mixup with the alternate air being associated with alternate static... so maybe you can look into that?
