No, you mechanically change a valve that changes the air intake to air that runs past the exhaust manifold and is therefore heated.

Hydraulically driven by 2 electric pumps with a 7 second transit.

Make sure to memorize the emergency procedures for your previous aircraft, example answer:

Engine powers max (mixture, rpm, throttles) Identify and verify failed engine Throttle close Propeller feather Mixture idle cutoff Gear and flaps up Magneto switches off Fuel pump off Fuel selector off CHECK FOR FIRE R/T call

This depends on weight, C.G., temperature and density.

This altitude is usually where the combination of L/D ratio and engine efficiency are maximized.

Seneca uses MOGAS (red) or AVGAS (Blue)

The engine will flood with fuel.

Alternate air is an alternate source of air, it can for example be used during ice, when the normal filter is blocked to have a backup source available.

Alternate air is unfiltered air and should not be used during ground operation because the unfiltered air may contain dust and other contamination.

Easier for the company in regards to training, maintenance and spare parts as you only use one type of aircraft.

No, it’s not required as the Seneca has a fuel injection system and engine icing normally forms around the venturi of the carb.

Ice can still form in in a fuel injection system in icing conditions, an alternate air source is available in this situation which takes warm air from inside the engine cowling.
