A

Aft CG = Increased Vmc

28
Q

How does a FEATHERED prop vs a WINDMILLING prop affect Vmc?

A

Feathered Prop = Decreased Vmc

- Windmilling prop increases Vmc and has -200fpm performance cost

29
Q

How will DECREASING weight affect Vmc?

A

Decreased WT = Increased Vmc

30
Q

TRUE or FALSE: Stall speed and Vmc DECREASE as density altitude INCREASES (assume normally aspirated engine)

A

TRUE

31
Q

TRUE or FALSE: In all multi-engine a/c stalls will always occur before losing directional control

A

FALSE (D.A. and IAS chart!!!)

32
Q

TRUE or FALSE: Vmc is calculated with the inoperative engine’s propeller windmilling unless the a/c is equipped with an auto-feathering system

A

TRUE

  • “The a/c will be left with a windmilling propeller” pg 151
  • Props and in T/O position
33
Q

TRUE or FALSE: If the pilot uses the wings level method for the a/c control following an engine failure the a/c is considered in coordinated (no slip or skid)

A

False…

34
Q

TRUE or FALSE: To achieve maximum performance single-engine the pilot should pitch for Vyse and establish zero sideslip

A

True

35
Q

In the Piper Seminole’s gear system, what shuts the pump OFF during gear retraction?

A
  • Pressure switch reaching approx 1800 psi
36
Q

The squat switch on the Piper Seminole’s RIGHT main gear:

A
  • Disables lift detectors on the on the wing to prevent stall warning horn on ground
  • Activates mx hobbs
    (b and c)
37
Q

Which of the following electrical buses in the Piper Seminole’s electrical system has power regardless of the a/c’s master switch position

A

Battery Bus

38
Q

When the RIGHT fuel selector is in the X-FEED position in the Piper Seminole the:

A
  • The LEFT Engine is drawling fuel from the LEFT Tank

- The RIGHT Engine is drawling fuel from the LEFT Tank

39
Q

What does FAR 23.149 define?

A
  • Minimum Control Speed (Vmc)
  • CAS at which, when the critical engine fails, it is possible to maintain Directional Control of the a/c

(maintain straight and level flight at the same speed with no more than 5 degrees bank)

40
Q

What 13 certification requirements/conditions are used to determine an a/c’s Vmc?

A
  1. Critical Engine is failed
  2. Directional Control is maintained
  3. Bank Angle is 5 degrees or less
  4. No more than 1.2Vs1
  5. A/c is at most unfavorable CG and weight
  6. Airborne (out of ground effect)
  7. Max. power on both engines
  8. Cannot reduce power on either engine
  9. A/c is trimmed for takeoff
  10. Gear is up, Flaps and Props in T/O condition
  11. 150lbs Max force on Rudders
  12. A/c must not enter unusual attitudes
  13. No heading changes greater than 20 degrees
41
Q

WHY is it important to know the parameters under which Vmc of our a/c was determined?

A

SO THAT WE KNOW THE PERFORMANCE OF OUR A/C IN AN ENGINE OUT SITUATION

42
Q

What are the 4 factors that MAKE the Left engine critical on a conventional twin? Explain them.

A
  1. P-Factor - (Propeller Factor) greater lift/thrust is created by descending prop blade, causing asymmetric thrust and left turning tendencies (eliminated on counter-rotating twins)
  2. Accelerated Slipstream - Accelerated air on the side with the DESCENDING prop blade create greater lift vector (think of picture)
  3. Spiraling Slipstream - Propwash impacts LEFT side of vertical stabilizer/rudder
  4. Torque - For every action there’s an equal and opposite reaction
43
Q

What are the 3 types of Hydroplaning?

A
  1. Dynamic - Tires sit on top of water on runway (9 x Square root of the Tire Pressure)
  2. Viscous - Altered runway surface (paint)
  3. Reverted Rubber - Friction turns water into steam that is so hot it melts the tire
44
Q

What is the Absolute Ceiling for an a/c?

A

The altitude at which you can no long maintain a climb rate (0 fpm)

45
Q

What is max T/O weight AND certified Landing weight for the Piper Seminole?

A

3,800lbs

46
Q

What is mx RAMP weight for the Piper Seminole?

A

3,816lbs

47
Q

TRUE or FLASE: Vmca is a stalled condition

A

TRUE!!!!!

Q

What is powered by the Emergency Battery?

A 
....bitch get in that POH
COM 1
NAV 1 
STBY Instruments
Audio Panel
Avionics Lighting
49
Q

Why is Vlo (ret) lower than Vlo (ext)?

A
  • Pump must work harder when gear is being retracted

- Gear door limitations

50
Q

Why do we have a Vlo (ext) speed?

A

Due to gear DOOR limitations!

51
Q

The Piper Seminole’s landing gear is ____ powered, and ____ operated.

A
  1. Electrically Powered
  2. Hydraulically Operated
    (electrically powered hydraulic pump)
52
Q

What instruments in the Piper Seminole operate off the vacuum system?

A

NONE!
There is no vacuum system because the Seminole does not have any gyroscopic instruments, they are ALL electrically driven!

53
Q

What part of the Seminole is most likely to accumulate ice the fastest?

A

The tail!

54
Q

What are the 2 categories of Autopilot?

A
  1. Attitude Based
    - More accurate
  2. Rate Based
    - Pressure changes
    - Independent static sources
    - Lag a little
55
Q

What are the 3 axis categories Autopilot can cover?

A

1 Axis: Roll
2 Axis: Roll + Pitch
3 Axis: Roll + Pitch + Yaw

56
Q

What is Basic Empty Weight?

A

Standard empty weight plus optional equipment

57
Q

When the aircraft leave ground affect, what happens to Vmc?

A

Out of ground affect = INCREASED Vmc

58
Q

When power is reduced on the operative engine, what happens to Vmc?

A

Power reduced = Decreased Vmc

59
Q

If Density Altitude is a LOWER VALUE, how is Vmc affected?

A

According to Lovelace, Vmc will Increase with an decreased Density Altitude value.
