Multi: prop moves toward coarse

Question 14

Fuel to air ratio at recommended lean

Answer 14

1:15 by weight

Question 15

Pitot tube blocked partially/totally

Answer 15

Totally: ASI behaves like altimeter
Partially: ASI goes to zero

When to set altimeter when transitioning to/from SPR

Answer 16

Always on the SPR side

Question 17

Octane/heptane characteristics

Answer 17

Heptane = Volatile component of fuel
Octane = Non-volatile component of fuel

Question 25

What is mountain effect?

Answer 25

Wind rushing around mountains of through valleys lower pressure in the area causing altimeter to read too high (true altitude will be lower)
