Aircraft general knowledge

Carburetor ice is detected when the engine speed drops, and the aircraft does

not maintain the altitude to which it has been trimmed. If this is detected, you

should not just give more throttle but check for ice by using carb heat.

The diagram here

shows the

conditions under

which carburetor ice

forms.

8.9.3 Carburetor heat

We have a third control lever that ensures that hot air is supplied to the

carburetor preheating, so that we have the option of supplying hot air to the

carburetor to counteract or remove ice.

Here you can see the

principle of carburetor

preheating.

Normally, there is air intake

through the air filter.
