How would Vmca and performance be affected by applying maximum available takeoff power?
Vmca = increase Performance = increase

Vmca = decrease Performance = decrease
How would Vmca and performance be affected by propellers in the takeoff position (high RPM)?
Vmca = increase Performance = increase
How would Vmca and performance be affected by landing gear retracted?
Vmca = increase Performance = increase
How would Vmca and performance be affected by having the most unfavorable CG? AFT CG
Vmca = increase Performance = increase
How would Vmca and performance be affected by the critical engine failed?
Vmca = increase Performance = decrease
How would Vmca and performance be affected by applying no more than 5 degrees of bank into the operative engine?
Vmca = decrease Performance = increase
How would Vmca and performance be affected by having the most unfavorable weight (light weight)?
Vmca = increase Performance = increase
How would Vmca and performance be affected by applying takeoff flaps (no flaps)?
Vmca = increase Performance = stay the same
How would Vmca and performance be affected by being out of ground effect?
Vmca = increase Performance = decrease
How would Vmca and performance be affected by trimmed for takeoff?
Vmca = decrease Performance = increase
How is Vyse depicted on the airspeed indicator?
blue line
How is Vmc depicted on the airspeed indicator?
red line
What is the difference between Vmc and MCA
Vmc is specific to multi-engine aircraft
MCA is minimum control airspeed, every aircraft has one
What is Vmcg
minimum control speed on the ground
What is a spin?
an aggravated stall that results in an airplane descending in a helical, or corkscrew path.
What will the flight instruments read in a spin?
Airspeed indicator = relatively constant, close to stall speed
VSI = consistent descent
Rate of turn = show direction your turning
What engines does the carbureted Seminole have?
O-360-A1H6 (Left engine)
LO-360-A1H6 (Right engine)
What engines does the fuel injected Seminole have?
IO-360-B1G6 (Left engine)
LIO-360-B1G6 (Right engine)
What type of carburetor does the Seminole have?
A side draft carburetor, which helps decrease the chance of carb ice because it is on the side versus the very front of the engine
What drives the propeller to high pitch, low RPM?
Nitrogen charge
Mechanical Spring
Counterweights
What drives the propeller to low pitch, high RPM?
Oil pressure
Aerodynamic twisting force
What does the unfeathering accumulator do?
stores and boosts oil pressure so you don’t need to use the starter to start the engine back up after feathering
How many pressure switches are there on the seminole landing gear? What are the pressure switches on the seminole landing gear?
9
3 up limit switches
3 down limit switches
1 pressure switch
2 squat switches on mains
What does the left squat switch do?
prevents gear retraction on ground
turns off the heater blower
What does the right squat switch do?
starts MX hobbs
turns on the stall warning horn
When would you get a check gear annuciation?
- MAP below 14” Hg
- Flaps greater than first notch
- Gear is selected up on the ground
- Below 400’ AGL
What are the stages of a spin?
Entry
Incipient
Fully Developed
Recovery
What are some factors that affect stall speed?
Weight C.G. Load factor Bank Aircraft config Wing contamination
Risk vs Hazard
A hazard is something that can cause harm. A risk is the chance, high or low, that any hazard will actually cause somebody harm.
What are the factors that affect a multi-engine aircraft while operating under 1 engine.
P-factor
Accelerated Slipstream
Spiraling Slipstream
Torque
The Piper Seminole has a total fuel capacity of [_]gallons, the total usable fuel is
[__]gallons.
110, 108
Zero side slip condition in the Piper Seminole is identifed as:
½ ball deflection and 2-3 degrees of bank.
What does the O stand for in the engine name?
Horizontally Opposed Cylinders
What does the 360 stand for?
360 cubic inches of cylinder displacement
Is our engine air cooled or liquid cooled?
air cooled
What is the Oil Pressure minimum psi?
15 PSI
What does the Carburetor do?
Controls the fuel and air mixture
What temperature range is Carb Icing most common?
Between 20-70 Fahrenheit
What are two ways that Carb icing can be identified by?
Identified by loss of Manifold Pressure
Identified by engine roughness
Where does the Carb heat come from?
Heat comes from the exhaust shroud
Why do we not want to takeoff with Carb heat?
The heated air used by the engine is less dense than the outside air and will result in a drop in engine power.
You notice a high CHT and engine temperature. What will you do? (4)
Open cowl flaps
Retard throttle
Lower nose; increase airspeed
Enrichen mixture
What type of Propellers do we have? How many blades? (3 more items to memorize)
Hartzell, two-blade, controllable pitch, constant speed, full-feathering
What does Controllable Pitch mean?
Pilot can control engine RPM by changing the pitch of the propeller blades
What does Constant Speed mean?
Propellers will maintain at a constant RPM regardless of power setting
