Q

What does the oil system do?

A

provides a constant supply of filtered

Q

CAUTION: When must the oil system be serviced?

A

within 30 minutes
of engine shutdown. For most accurate
results, check oil level 15 to 20 minutes after
shutdown.

Q

How do you check oil level?

A

The sight glass is not to be used for checking
oil level; only the dipstick is to be used for
correct indication of oil level in the tank.

Q

How is oil pressure and temperature measured?

A

Sensed by transducers downstream of the main oil pump and the signal is sent to the engine data manager (EDM). The EDM passes the oil pressure data to a signal conditioning unit (SCU) computer that contains the logic to illuminate the warning annunciators on the central warning system (CWS) panel under the
following conditions.

Q

When will the red oil pressure annunciator be illuminated?

A

When oil pressure drops to 40 psi or below with PCL above idle, or when oil pressure drops to 15 psi or below at PCL in idle.

Q

To which pressure altitude do you have 100% torque on a standard day?

A

12,000 to 16,000 feet MSL

17
Q

How many HP is the engine producing at 100% torque?

A

approximately 2900 foot-pounds of torque at the prop shaft. This equates to approximately 2750 pounds of thrust at sealevel, zero airspeed.

18
Q

What are the three basic conditions in relation to the propellor pitch?

A

Feathered, low pitch (flat or fine), and high pitch (coarse).
