16
Q

Why is the opposed engine design the preferred cylinder configuration for small
aircraft engines?

A

the configuration provides the best balance between the factors
which an airplane manufacturer would choose

17
Q

What forces in the Piper Seminole Propeller system will drive the propeller to a
low pitch/high RPM during an under-speed condition?

A

boosted oil pressure from the propeller governor

centrifugal twisting force

18
Q

In an overspeed condition, the propeller blade will adjust to a __________ pitch
angle in order to maintain the desired RPM.

A

higher

19
Q

T or F) Because of the different velocities along the blade length the standard propeller is
designed so the hub has a thinner prole and less camber than the propeller tips.

A

False

20
Q

What is the purpose of the “accumulator” on the Piper Seminole’s propeller system?

A

stores oil pressure to allow the propeller to be unfeathered without the
use of the starter in order to reduce wear and tear on the starter motor

21
Q

When operating the Piper Seminole, why is it important to bring the propeller control
fully into the feather detent position prior to reaching 950 RPMs or less?

A

anti-feathering pins will engage preventing the propeller from sliding into
the high pitch (feather) position

22
Q

What type of propeller allows a pilot to mechanically select either a cruise prop
pitch or climb prop pitch prior to departure?

A

ground adjustable

23
Q

During which stroke of the four-stroke engine cycle does the rapid air expansion
caused by the burning of the fuel-air mixture drive the piston downward?

A

power

24
Q

What form does a pilot use and who do they submit it to when requesting a ferry
permit?

A

Form 8130-6 submit to the local FSDO having jurisdiction where the
flight will occur

25
Q

What does it mean when an engine has dual-cam?

A

it has two different cam shafts with four valves per cylinder to
increase engine performance

26
Q

During which stroke of the four-stroke engine cycle will the exhaust valve open to
allow for the scavenging/purging of the burned fuel/air mixture within the
cylinders?

A

power

27
Q

During which stroke of the four-stroke engine cycle will internal operating
pressure within the cylinder peak?

A

POWER

28
Q

The force acting on a propeller that tends to pull the propeller blades away from
the hub is called:

A

Centrifugal

29
Q

During which stroke(s) of a four-stroke engine will the intake and exhaust valves
both be open?

A

at the end of the exhaust and beginning of the intake strokes

30
Q

When a constant speed propeller system is installed on a single-engine aircraft,
boosted oil pressure from the hub will work aerodynamic forces to drive the propeller
toward a __________ in order to act as a fail safe mechanism.

A

high pitch/low RPM position

31
Q

In an overspeed condition, the pilot valve in the prop governor will ________
allowing oil to __________ the propeller hub

A

raise; leave

32
Q

The difference between effective and geometric pitch is known as?

A

slippage

33
Q

Which major aircraft engine manufacturer numbers cylinders from the rear
moving forward with odd cylinders on the right and event cylinders on the left?

A

Teledyne Continental

34
Q

Which of the following is permissible preventative maintenance item that may be
completed by anyone who holds a pilot certificate (student pilot to ATP)?

A

none of the above

35
Q

The Cylinder Head Temperature gauge on the G1000 shows the #4 cylinder is
running hot on your Piper Archer, what cylinder is affected?

A

left rear cylinder

36
Q

The force acting on a propeller that tends to cause the blade tips to ex forward
while the hub remains stationary when thrust is produced is classed:

A

Thrust bending

37
Q

A cylinder in a ___ stroke engine will complete its operating cycle after two full
rotations of the crankshaft.

A

4

38
Q

Low pitch/high rpm

A

centrifugal twisting force

boosted oil pressure
