Multi

Question 1

Vxse

Answer 1

Best angle of climb with one engine inoperative

Question 2

Vyse

Answer 2

Best rate of climb with one engine inoperative; marked with a blue line

Question 3

Vsse

Answer 3

Safe, intentional OEI speed

Question 4

Vref

Answer 4

reference landing speed–an airspeed used for final approach, which is normally 1.3 times Vso

Question 5

Vmc

Answer 5

Defined in CFR 23.2135(c): the calibrated airspeed at which, following a sudden engine loss, it is possible to maintain control of the aircraft. Marked with a red line

Question 6

Vlof

Answer 6

liftoff speed

Question 7

Under what conditions are V-speeds given in the POH true (unless otherwise noted?)

Answer 7

Sea level, standard day, max takeoff weight

Question 8

Aerodynamic forces acting upon a windmilling propeller tend to drive the blades to:

Answer 8

low pitch (high drag), high RPM

Question 9

Counterweights attached to the prop drive the blades:

Answer 9

high pitch (low drag), low RPM

Question 10

The force of oil pressure through the propeller governor pushes the blades to:

Answer 10

low pitch, high RPM

Question 11

With a loss of oil pressure through the prop governor, the blades fail to what position?

Answer 11

high pitch (low drag), low RPM

Question 12

The prop counterweights are insufficient to completely feather the prop at lower RPMS; what provides the “final” force to do so?

Answer 12

Either a spring or a nitrogen charge

Question 13

What prevents the propellers from feathering every time the engine is shut down? (given the loss of oil pressure)

Answer 13

Typically, below ~800RPM, a reduction in centrifugal force allows small anti-feathering lock pins to move into place. The prop must be feathered prior to below 800 RPM

Question 14

Accelerate-go distance

Answer 14

the distance required to continue the takeoff and clear a 50 foot obstacle assuming an engine failure at Vr or Vlof

Question 15

Define: all-engine service ceiling

Answer 15

The highest altitude a multi engine plane can maintain a 100 FPM climb

Question 16

Define: single engine service ceiling

Answer 16

the highest altitude at which the aircraft can maintain 50 fpm OEI

Question 17

basic empty weight

Answer 17

Standard empty weight + optional equipment

Question 18

Standard empty weight

Answer 18

airplane, hydraulic fluid, unstable fuel, full oil

Question 19

zero fuel weight

Answer 19

the maximum allowable weight of the airplane and payload, assuming there is no usable fuel on board

Question 20

Forward CG characteristics

Answer 20

more stable, higher stall speed, slower cruise, favorable stall characteristics

Question 21

Aft CG characteristics

Answer 21

less stable, slower stall speed, higher cruise, less desirable stall characteristics

Question 22

WYD: An engine fails prior to Vmc during the takeoff roll

Answer 22

Abort the takeoff

Question 23

AFM recommendation for a slow flight minimum altitude

Answer 23

3000 ft

Question 24

How do you enter a spin in a multi engine airplane?

Answer 24

Stall and yaw. Either rudder or asymmetric thrust

Question 25

When should a single-engine go around be considered?

Answer 25

Almost never

Question 26

Why does Vmc decrease with altitude?

Answer 26

Because Vmc is greatest with greatest available power, and power decreases with altitude (normally aspirated only)

Question 27

Why is Vmc higher when the inop engine is windmilling?

Answer 27

Because, unfeathered, it’s producing more drag

Question 28

Why does Vmc increase as the CG moves aft?

Answer 28

Because the moment arm of the rudder is reduced

Question 29

How does Vmc change when you extend the landing gear?

Answer 29

It decreases, as the landing gear provide directional stability

Question 30

Is 5 degrees the optimal bank angle in OEI operations?

Answer 30

Not necessarily; it’s a historical maximum for Vmc determination

Question 31

Why does Vmc decrease with increasing bank?

Answer 31

Because the horizontal component of lift balances the side force of the rudder, requiring less rudder deflection

Question 32

What if the engine fails on takeoff prior to landing gear up?

Answer 32

Probably you land straight ahead
