Throttle Mixture Tutorial

[RacingLad]

So I should takeoff with a lean mixture and then richen as I gain altitude?

You see, I flew tha Baron 58 recently with the mixture lever full forward and climed to 7,000 feet. But the best speed it could summon was 140 kts. I only moved the mixture back a couple of notches and still 140 kts was the best I could squeez. I read elsewhere that the Baron's cruising speed should be 200 kts...

Could that be the problem?

Most likely...

200 knots is a bit optimistic though, you probably won't get more than 185 KIAS out of it.

Lean the mixture correctly (pull out until the EGT peaks, then forward a notch).

And check the rest of the plane, cowl flaps should be closed, gear and flaps up.

As long as Santa Claus is providing this eqipment, you might ask for the new switch panel Saitek is shipping this holiday season also.

Okay well my grandpa let me use his new yoke, throttle, and rudder pedals and after reading you guys above I think I got the Mixture but I might have to read more about it but how does the prop work (the blue one)

Thanks

The exact opposite. Full rich(forward) for take-off, and lean out at cruising altitude(above3000ft)

If that model is accurate (and I believe it is, because Liberty gave our club a FS9 version when we bought a Real Liberty XL2).. It will have a "modified" mixture control. Individual cylinder mixtures (along with timing) are controled by the' FADEC' system... Trying to make FADEC work within the constraints of the MSFS flight model, is probably some form of "auto-mixture". That's why it's seems weird.

[Brett_Henderson]

Oops.. sorry.. I forgot to answer your question.  Just lean it like normal..  Lean until the temperature peaks.. and then richen slightly.

The Liberty has a fixed prop.. and funny you ask.. if you search the photo forum.. you'll see pictures of ours after a bounced landing and prop-strike... AND I posted something about the night when the prop came OFF !!!

[Brett_Henderson]

Yeah.. it's kinda like a jinxed airframe to me.

I wasn't in the Liberty when the prop came off. I did get to inspect the wreckage though..  All of the studs that secure the prop were sheared off clean.. so we're thinking he hit a BIG bird. The prop never touched the wings or fuselage... months later, it was recovered in a farm field (mangled beyond being useful evidence).

I got to listen to the tower tapes. The tower guy was visibly shaken (we all know each other pretty well), but my mentor was almost humorously calm.. "Umm tower.... I got a mayday here"..

He said he just looked for the darkest spot on the ground and aimed for it. Turned out he landed in a corn field, flying JUST under some power lines.. Later talking to the tower by cell phone, as a copter guided the ambulance to the scene. He had a female passenger with him.. nobody was injured at all..

The finger brakes are right near the throttle..  Meaning that you have one less hand while taxiing... and it's a tricky finger dance to modulate the throttle AND apply differential brakes for steering (I forgot to nebtion that the nose wheel casters.. so the only low-speed ground steering IS those brakes).

It's not my favorite airplane..lol

Is managing cowl flaps anywhere in these threads? Is there a rule of thumb regarding these devices?

Wide open on the ground..  Then it becomes aircraft dependent. For most small props, it's wide open for takeoff and climb too.. and then varying degrees of closed depending on airspeed and OAT.. keeping an eye on the CHT.
