- What is the maximum demonstrated crosswind component?
17 KIAS
- Describe the Seminole PA-44-180 engine. A. How many cylinders?
4
- B. Who is the manufacturer?
Lycoming
- C. What is the horsepower rating?
180
- D. Does it have fuel injectors or a carburetor?
carbureted
- E. Is the engine turbo-charged or normally aspirated?
normally aspirated (no turbo or supercharging)
- F. Why is the right engine labeled LO-360?
The right engine is designated as an LO-360 due to the fact that it rotates to the left
- G. How are the cylinders arranged?
horizontally opposed (pistons oppose each other)
- H. How is ignition provided?
Engine ignition is provided through the use of engine-driven magnetos which are independent of the aircraft’s electrical system and each other.
- I. What are the minimum and maximum oil capacities in the 1979 and 2000 model Seminoles?
Oil Capacity 1979 = 4 to 6 Quarts, ATP Minimum 4.5 Quarts. 2000 = 6 to 8 Quarts, ATP Minimum 6.5 Quarts
- Describe the propeller system. A. Who makes the propellers?
Hartzell
- B. What does oil pressure do to the propeller?
When the blue propeller control handle is moved forward, oil pressure, regulated by a propeller governor, drives a piston, which moves the blades to a low pitch–high RPM (unfeathered) position. When the blue propeller control handle is moved aft, oil pressure is reduced by the propeller governor.
- C. Which lever manipulates oil pressure to the propeller?
blue propeller control handle
- D. Which unit regulates oil pressure to the propeller?
regulated by a propeller governor
- E. What is the function of the nitrogen cylinder?
a nitrogen-charged cylinder, spring, and centrifugal counterweights to drive the blades to a high pitch–low RPM (feathered) position.
- F. What is the purpose of the spring in the prop dome?
a nitrogen-charged cylinder, spring, and centrifugal counterweights to drive the blades to a high pitch–low RPM (feathered) position.
- G. Define constant speed.
Constant speed propeller –changes in power setting (manifold pressure) and flight attitude will not cause a change in RPM.
- H. What unit adjusts the propeller to maintain a constant RPM and how does it do it?
After RPM setting is selected with the blue propeller control handles, the propeller governor will automatically vary oil pressure inside the propeller hub to change the propeller blade pitch in order to maintain a constant engine RPM.
- I. Define full feathering.
When the propeller blades are in alignment with the relative wind, they are feathered. Feathered propeller blades reduce the drag caused by the blade area exposed to the relative wind.
- J. Will the propeller always feather?
The Seminole is equipped with a centrifugal stop pin that prevents propeller feathering below 950 RPM.
- K. What are centrifugal stop pins?
The Seminole is equipped with a centrifugal stop pin that prevents propeller feathering below 950 RPM.
- L. What is the true purpose of the centrifugal stop pins?
The purpose of this is to allow the propeller blades to remain in a low pitch upon engine shutdown. This will prevent excessive loads on the engine starter during the next engine start.
- What is the correct action for a propeller overspeed?
If propeller overspeed should occur, retard the throttle. The propeller control should be moved to full “DECREASE RPM” and then set if any control is available. Airspeed should be reduced and throttle used to maintain a maximum of 2700 RPM.
- Describe the electrical system
The Seminole is equipped with a 14-volt electrical system which utilizes pushpull type circuit breakers; a 12-volt, lead-acid battery; and two 70-amp, enginedriven alternators. Voltage regulators maintain constant 14-volt output from each alternator at varying engine RPMs, effectively sharing the electrical load.
- What are the indications of a failed alternator?
Loss of one alternator is indicated by an annunciator light and a zero indication on the loadmeter. The remaining alternator will normally provide adequate electrical power.
- Will the engines continue to run with the alternator and battery master switches turned off?
engine-driven magnetos which are independent of the aircraft’s electrical system and each other.
- Describe the vacuum system. A. Which instruments are vacuum operated?
The vacuum system operates the attitude gyro and, on aircraft without slaving mechanisms installed, the HSI.
- B. What are the normal vacuum operating limits?
Suction limits are 4.8 to 5.2 inches of mercury at 2000 RPM.
- C. How many vacuum pumps does the PA-44 have?
The Seminole is equipped with two engine-driven vacuum pumps.
