Carb Heat

[scottyboy75]

I was writing this for a safety meeting we have coming up so I thought I could post it here as well.
With the winter months here we need to look at the use of carb heat. page 4-11 in the Robinson POH covers the use of carb heat. At temps between 80 degrees f and 25 degrees f carb heat should be applied whenever there is visible moisture present also when the dewpoint spread is less than 11 degrees. When training students for autos then ignore the carb temp guage and apply full carb heat as the manifold pressure will be below 18 inches and ice could build in the venturi not allowing for power recovery during the flare portion of the procedure. This has caused multiple accidents in the past. Let us not have it happen to us. Remember "stay alert; stay alive."

Having flown FW, and then getting in the R22, remembering the carb heat was the biggest issue for me. I can still hear my instructor now reminding me to check the carb heat.

How's the instructing going? Have you got any job offers flying elsewhere?

Helicopters with carburetors - just f-ing weird!

Instructing is going well. I have most of my guys hovering proficently around 5-7 hrs. I have sent out some resumes to diferent schools but we will see how that goes. Helo scools are funny about hiring only from there grads.

Scottyboy,
You're right, most want to take their grads to fill CFI positions. My instructor has told me some stories of guys he's flown with who trained elsewhere to fill positions...

It is kind of a weird culture. There is one school in particular that wants students to be able to state word for word the type of construction of the tail cone. That seems excessive in my book. I want my students to know the principals of flight, the important details of the aircraft they fly. Do I care if they can tell the tail is a monocoque structure in which the aluminum skins carry most of the loads? It does not affect their abilities of handling the aircraft in flight. As time goes on I think they should have more of an indepth knowledge of the aircraft but that comes with experience and time in the seat.

I was thinking the same thing. I can't imagine flying a helo with carb heat or a tachometer. Just doesn't seem right.

When I flew a Scweizer I kept looking for a torque gauge. Seeing a MP gauge was really strange.

(PS - how's my boy George doing?)

Well, I guess there is one bright side. I bet you can't over-torque em'

Or can you?? I wouldn't have thought so, I figure a piston engine is putting out a lot less power, at a far lower RPM then what we flew.

Always used to get on my nerves, the transmission being the "Weakest link" in the drivetrain.


BTW. George is doing fine so far, and I hope it stays that way. We are having problems.

I don't think so - no more than you could a piston airplane engine. In fact, I think that Scweizer I flew had a regular old Lycoming IO 360 in it.

Funny about how training affects you though - I was doing autos terminating in a hover in that thing and was a real wussy about sucking in the power at the bottom after rolling the throttle back on thanks to only flying turbines. Bounced the skids once because I feared I was going to "over-torque" it.

Autos to a hover is typical wussy civilian rotorcraft flying to begin with!

That's what skid shoes, or in your case wheels, were for!!

Military twin engine flying is wussie.
I kid btw I look at the Blackhawks down the ramp like a security guard looking at a cop car.

Blackhawk's?!? You poor thing.....


Ian- Got my 2nd goggle hookup last night...
