Regarding the Emergency electrical sw: when is IFR flight not permitted?

When the seal on the emergency switch is broken

What material is used to form the fuselage and flight controls?

Carbon Fiber Reinforced Plastic and Glass Fiber Reinforced Plastic. GFRP/CFRP Composite Sandwich.

What does the emergency switch provide voltage for?

Attitude gyro and flood light

How long does the emergency switch provide voltage for?

1.5 hours

Can you take off in IFR conditions if the safety wire on the Emergency switch is broken?

What are the electrical buss’s on the DA40?

Hot Battery Bus, Battery Bus 1, Battery Bus 2, ECU Bus, Main Bus, Essential Bus, Avionics Bus

What is the meaning of RACC?

Recirculating Air - Cabin Cooling

What are the minimum altitudes for autopilot operation?

Must be disengaged below 200’ AGL during approach and 800’ for all other phases of flight.

What is the maximum & minimum speed for autopilot engagement?

Max. = 165 KIAS Min. = 70 KIAS

When do the red chevrons appear on the PFD?

50* pitch up and 30* pitch down

What is the max commanded pitch up and down by the auto pilot?

Type of engine in the DA40NG?

Austro Engine (E4-A), inline construction, liquid-cooled, common rail direct injection, turbo charged with intercooler, constant speed prop, propeller speed reducing gearbox.

What is the definition of Vo?

Maximum operational maneuvering speed (Vo) is a speed where the airplane will stall in a nose-up pitching maneuver before exceeding the airplane structural limits.

How many fuel pumps does the fuel pump switch activate?

Activates both ECU fuel pumps.

Are the EECU pumps high or low pressure pumps?

Low pressure

Is the engine driven fuel pump a high or lower pressure pump?

High pressure

What is the gliding distance of the DA40NG with wheel fairings?

Where does the propeller governor get the oil to change blade angle?

The gearbox has its own oil supply.

What causes the propeller to move to a higher pitch?

Higher oil pressure pushes on the spring in the hub, which forces the blades into a higher pitch.
