Checkride Prep - Airplane Systems (Cessna 172N POH)
1. What type of engine does your aircraft have?: A Lycoming, normally aspirated, direct-drive, air-cooled,
horizontally-opposed, carburetor equipped, four-cylinder engine with a 320 cu. in. displacement.
2. What is the horse power and engine rpm for your aircraft?: 160 rated BHP, 2700 RPM.
3. What type of propeller does your aircraft have?: A fixed pitch propeller.
4. What type of fuel is approved for your aircraft and what are the associated fuel
colors?: 100LL Grade Aviation Fuel (blue), and 100 Grade Aviation Fuel (Green).
5. What is the total and usable fuel capacity for your aircraft?: 43 total gallons, with 40
usable gallons.
6. What type of oil does your aircraft use?: MIL-L-22851 Ashless Dispersant Oil.
7. What is your aircrafts oil capacity?: 8 quarts
8. What is the max weight for your aircraft in the normal category?: 2300 lbs
9. What is the VNE for you airplane?: 160 KIAS
10. What is the VNO for your airplane?: 128 KIAS
11. What is VA at max weight for your aircraft?: 97 KIAS
12. Does VA increase or decrease with a weight increase?: VA speed increases with a weight
increase.
13. What is the VFE for your aircraft?: 85 KIAS
,14. What is the short field obstacle clearance speed for your aircraft?: 59 KIAS (with
no flaps)
15. What is the obstacle clearance speed for 10 degrees of flaps, when taking off
from a soft field?: 55 KIAS
16. What are the procedures for an over-primed aircraft during starting proce-
dures?: It is necessary to clear the excess fuel from the combustion chambers. Set the mixture control to full lean and the throttle
to full open; then crank the engine through several revolutions with the starter. Repeat starting procedure without any additional
priming.
17. If the engine does not fire while starting what should you do?: This indicates that
the engine is underprimed, therefore you should do additional priming.
18. During an magneto check, what does a lack of RPM decrease indicate?: Indi-
cates faulty grounding of the P-lead wire on one side of the ignition system or should be an indication that the magneto timing is
set in advance of the setting specified.
19. What precautions should be taken when taking off on loose gravel?: Full power
should be applied smoothly and slower than normal to avoid gravel being sucked into the propeller and engine.
20. At what altitude should the mixture be leaned for takeoff?: Above 3000 feet elevation.
21. When should slips be avoided?: With flap settings greater than 20 degrees.
22. How many spark plugs does each cylinder have?: 2 each (4x2=8 total)
, 23. What type of carburetor does your aircraft have?: It is equipped with an up-draft,
float-type, fixed jet carburetor mounted on the bottom of the engine. Fuel is delivered to the carburetor by gravity flow from the
fuel system.
24. How is the engine cooled?: 1. Primarily through ram air. 2. Secondarily by engine oil. 3. Lastly by the
mixture.
25. When the fuel gages indicate E, how much fuel is left in each tank?: 1.5 gallons in
each tank.
26. How is fuel measured in the aircraft?: Through two float-type fuel quantity transmitters.
27. When should you examine the fuel in your aircraft?: The first flight of every day and after
every refueling to check for water and contamination.
28. What type of brakes does your aircraft have?: The airplane has a single-disc, hydraulical- ly-
actuated brake on each main landing gear wheel.
29. What are some symptoms of impending brake failure?: Gradual decrease in braking
action after brake application, noisy or dragging brakes, soft or spongy pedals, and excessive travel and weak braking action.
30. What action would build braking pressure?: Pumping the pedals
31. How is electrical energy applied to your aircraft?: Through a 28 volt, direct-current system
powered by an engine-driven, 60 amp alternator and a 24 volt, 14-amp hour battery.
32. How many electrical buses does your aircraft have?: Two: Primary bus, and an Avionics
bus.
