Short range- 38 gallons (19 per wing)
Unusable Fuel:
Short range- 4 gallons (2 per wing)
2.5- Describe (or draw) the fuel system of your aircraft
Describe POH picture
2.6- Does the aircraft have a fuel pump?
No
2.7- If the fuel vent became blocked, what could happen?
Fuel starvation could occur. With no fuel, the engine will stop. The fuel requires 2 vents in order for it to flow freely

MIL-H5606 Hydraulic fluid
2.9- What are the recommended tire pressures?
Main Wheels: 29 psi
Nose Wheel: 31 psi
2.10- What type of flaps does your aircraft have?
Single-slot flaps
2.11- What type of ailerons does your aircraft have?
Frise differential ailerons
Frise= The lower part of the aileron sticks into the airstream below the wing when they go up
Differential= They go up more than they go down
This helps with adverse yaw
2.12- Is your aircraft equipped with an elevator or stabilator?
Elevator
2.13- Does the trim tab move in the same direction as the elevator ?
No
2.14- How does the cockpit heater system work?
A shroud installed around the exhaust muffler allows the air to be warmed before it is channelled into the cockpit
2.15- Of what does the winterization kit usually found on a small aircraft consist? When should it be used?
Two plates to partially cover the cowl nose cap opening, insulation for the engine crankcase breather line and a few placards.
It should be installed when the temperatures are consistently below -7°C.
2.16- What are the minimum/maximum engine temperatures for takeoff
Minimum- 38°C
Maximum- 118°C
2.17- What are the maximum load factors for the aircraft?
Normal:
Flaps Up: +3.8g/-1.52g
Flaps Down: +3g
Utility:
Flaps Up: +4.4g/-1.76g
Flaps Down: +3g
2.18- What does "maximum crosswind component" refer to?
It is the max crosswind for which adequate control of the aircraft has been demonstrated during takeoff and landing as part of the certification process. It is not considered to be limiting.
2.19- Determine the following for the aircraft:
a) Voltage of the electrical system
b) Voltage of the battery
c) Ampere strength of the alternator
d) ampere hours of the battery
a) 14 V
b) 12 V
c) 60-amp
d) 25-amp hour
2.20- How does the ammeter work?
It indicates the flow of current from the alternator to the battery or from the battery to the airplane electrical system.
2.21- In the event of the ammeter showing a complete deflection to the right and the voltage light illuminating, how would you handle this situation in flight?
-Master OFF (both sides)
-Master ON (both sides)
-Over-Voltage Light OFF
If over-voltage light illuminates again:
-Flight TERMINATE ASAP
An over-voltage sensor will automatically shut down the alternator. If this fails to solve the problem, the flight will be terminated.
2.22- If the ammeter was deflected to the left (an insufficient rate of charge) and the voltage light was illuminated, how would you handle this situation in flight?
-Alternator OFF
-Nonessential Electrical Equipment OFF
-Flight TERMINATE ASAP
Continuous discharge of the battery indicates that the alternator is not supplying power to the system and should be switched off. All non-essential equipment should be turned off and the flight terminated as soon as practicable.
2.23- How can you determine a high/low, or over-voltage, situation
The red voltage light will indicate an overcharge or undercharge situation. The ammeter will indicate which situation actually exists.
2.24- In the event of a total electrical failure, how will it affect the magnetos?
It will not affect the magnetos at all. The magnetos run off the crankshaft. They are independent of the aircraft's electrical system. Therefore, if you turn the master switch off, the magnetos will not be affected, nor will the engine.
2.25- Name the pitot-static instruments
VSI
Altimeter
Airspeed indicator
2.26- Which pitot-static instrument(s) utilize the pitot tube? The static port?
Pitot tube: Airspeed indicator
Static Port: ASI, VSI, Altimeter
2.27- If the pitot tube gets blocked, which instruments will be affected? What about a static port blockage?
Pitot tube blockage: ASI
Static port blockage: ASI, VSI, Altimeter
2.28- How will the airspeed indicator react to a pitot tube blockage?
The ASI will over-read in a climb, and under read in a descent (act like an altimeter).
Drain hole not blocked : ASI slowly decrease to 0.
2.29- How will the airspeed indicator react to static port blockage?
The airspeed indicator will under read in a climb and over read in a descent (inverted altimeter).
2.30- How will the altimeter and VSI react to a pitot tube blockage? How will they react to a static port blockage?
Pitot- Altimeter and VSI are not affected by a pitot tube blockage
Static- The altimeter will freeze at the last reading before the blockage because the static pressure is trapped in the instrument.
-The VSI will indicate 0
2.31- Name the gyroscopic instruments
Attitude indicator
Heading indicator
Turn coordinator
2.32- How are the gyroscopic instruments powered
Powered electrically (TC) and by an engine driven vacuum pump (AI & HI)
2.33- How do you know if the information from the gyro instruments is reliable
-Check to make sure the suction gauge is green
-Check to make sure there are no flags
-Perform instrument check while taxiing
2.34- Name the major sources of error on the heading indicator
Bearing friction and the earth's rotation are the major sources of error on the heading indicator
2.35- How often must you reset the heading indicator? Under what conditions can you set it?
Should be reset at least once every 15 minutes. It can only be set in straight, unaccelerated flight; also in stabilized climbs and descents
2.36- Does the turn coordinator indicate the amount of bank?
No, it shows the rate of turn.
2.37- What is the inclinometer? How does it work?
The inclinometer is an instrument used to measure the attitude of an aircraft relative to the horizontal. It is usually made of a curved glass tube, partially filled with a clear liquid and holding a black ball made of glass, steel or agate.
The inclinometer works on the principle of gravity
2.38- How do you lean the mixture for best economy cruise? For best power?
Lean progressively:
-Peak RPM: max power
-RPM decreasing : best economy between that and peak RPM
2.39- What is the danger of running the engine too lean?
It can cause overheating and detonation
2.40- When you apply carb heat, why do you get a decrease in performance?
When carb heat is applied, hot air is introduced into the mixture. As hot air is less dense then cold air, the fuel to air ratio becomes richer, too rich for best performance. Therefore, when using carb heat for extended periods in cruise flight, it is a good idea to lean the mixture [Show Less]
