2120 RPM

21

Overspeed governor will limit prop to what?

2288 RPM 104%

22

The overspeed governor test switch will limit prop RPM to?

2050 RPM

23

Fuel topping governor (Nf) will limit prop RPM to?

6% above selected RPM

24

Time limit in reverse?

1 minute

25

What is the min and max observed oil pressure?

Normal oil pressure is 85-105 psi at Ng above 72% with oil temp between 60-70 deg c. Oil pressure below 85 psi is undesirable and should be tolerated only for the completion of the flight, preferably at reduced power setting. Oil pressure below 40 psi is unsafe and requires landing as soon as possible, using min power to sustain flight.

26

What is the min and max oil temp with t/o power?

10-99 deg c

27

Min and max oil temp at idle

-40 to 99 deg c

28

Min and max oil temp in reverse

0 to 99 deg c

29
