The correct answer is 108 gals (54 per side) because the Piper Seminole has a total usable fuel capacity of 108 gallons, with 54 gallons of fuel available on each side.

Submit
12. This is the capability of the propeller blades to align with the relative wind to decrease drag:

Explanation

Full feathering refers to the ability of the propeller blades to rotate parallel to the airflow, reducing drag. This feature is commonly used in aircraft to optimize performance during engine shutdown or in emergency situations. By feathering the propeller blades, the aircraft's drag is minimized, allowing for better glide performance and increased safety.

Submit
13. Gear retraction on ground is prevented by:

Explanation

The squat switch on the left main landing gear prevents gear retraction on the ground. This switch is designed to detect when the aircraft is on the ground and the weight of the aircraft is resting on the landing gear. When the switch senses this weight, it sends a signal to the aircraft's systems to prevent the gear from retracting. This safety feature ensures that the landing gear remains extended while the aircraft is on the ground, providing stability and support during taxiing, takeoff, and landing.

Submit
14. The Piper Seminole has the following wing flaps positions:

Explanation

The Piper Seminole has multiple wing flap positions, including 0, 10, 25, and 40 degrees. These positions allow the pilot to adjust the lift and drag characteristics of the aircraft during different phases of flight. The 0-degree position is likely used for takeoff and landing when maximum lift is required. The 10-degree position may be used for climb or cruise when a moderate amount of lift is needed. The 25-degree position may be used for approach and landing to provide additional lift and drag. The 40-degree position is likely used for short field landings or steep descents when maximum lift and drag are required.

Submit
15. The inboard stall warning detector provides stall warning at:

Explanation

The inboard stall warning detector provides stall warning at flaps 25 & 40. This means that when the aircraft is configured with flaps set at either 25 or 40, the inboard stall warning detector will activate and provide a warning to the pilot if the aircraft is approaching a stall. The stall warning system is crucial for flight safety as it alerts the pilot of an impending stall, allowing them to take appropriate action to avoid it.

Submit
16. The landing gear on the Seminole is:

Explanation

The landing gear on the Seminole is hydraulically actuated, which means that it is controlled by hydraulic power. This allows for smooth and efficient operation of the landing gear. Additionally, the landing gear is also electrically operated, meaning that it can be controlled and operated using electrical power. This combination of hydraulic and electrical operation ensures reliable and effective functioning of the landing gear system on the Seminole aircraft.

Submit
18. The squat switch has two functions on the Piper Seminole when it is on ground:

Explanation

The squat switch on the Piper Seminole has two functions when the aircraft is on the ground. One function is to remove power from the hydraulic pump, which helps to prevent unnecessary wear and tear on the pump. The other function is to deactivate the stall warning, as the aircraft is not expected to stall while on the ground.

Submit
19. Emergency landing gear extension is limited to:

Explanation

The correct answer is 100 KIAS. KIAS stands for Knots Indicated Airspeed, which is the speed at which the aircraft is moving through the air as indicated on the airspeed indicator. The emergency landing gear extension is limited to this speed to ensure the safety and effectiveness of the landing gear deployment. Going above this speed may cause damage to the landing gear or compromise the aircraft's stability during landing.

21. Regardless of the propeller lever position, what will happen when oil pressure is lost?

Explanation

When oil pressure is lost, the propeller will not feather regardless of the propeller lever position. However, if the RPM (Revolution Per Minute) is above 950, the propeller will feather. This means that the blades of the propeller will rotate into a position parallel to the airflow to reduce drag. If the RPM is below 950, the propeller will not feather, indicating that the propeller blades will remain in their current position.

Submit
22. This is the capability of a propeller to change the blade angle:

Explanation

Controllable pitch refers to the capability of a propeller to change the blade angle. This means that the pitch of the propeller blades can be adjusted in order to optimize the performance of the aircraft. By changing the blade angle, the pilot can control the amount of thrust generated by the propeller, allowing for better efficiency and performance in different flight conditions. This feature is particularly useful in aircraft with variable speed engines, as it allows for fine-tuning of the propeller's performance to match the engine's power output.

Submit
23. The landing gear horn will sound:

Explanation

The landing gear horn will sound when power is approximately below 15" with the landing gear up because this indicates that the aircraft is in a low-power configuration, which could be a potential hazard if the gear is not down. The horn also sounds when flaps 25 or 40 are selected and the landing gear is not down, as this indicates that the aircraft is configured for landing but the gear is still retracted. Additionally, the horn sounds when the landing gear handle is selected up on the ground, which is a safety reminder to ensure that the gear is down before takeoff.
