What is the maximum demonstrated crosswind component?
- 17 Knots
Describe the PA-28-181 engine.
How many cylinders?
- Four Cylinders
Describe the PA-28-181 engine.
Who is the manufacturer?
- Lycoming
Describe the PA-28-181 engine.
What is the Horsepower rating?
- 180 horsepower at 2,700 RPM
Describe the PA-28-181 engine.
Does it have fuel injectors or a carburetor?
- We have both at KCXO
Describe the PA-28-181 engine.
Is the engine turbo-charged or normally aspirated?
- Normally Apirated
Which means…..
- The air the engine is taking in, is all the air that the engine is getting. Our performance gets worse the higher up we go. So, the denser the air pressure is the worse our engine performance is and the lower our horsepower rating is.
- It is creating the same amount of horsepower no matter what altitude we are at.
Other types….
(Forced Induction, also known as turbo-charged or supercharged. The air is getting forced into the engine. You are getting more air molecules. Which means, you are getting the same performance no matter how high are low you are because the induction system is forcing extra air molecules in.)
Describe the PA-28-181 engine.
How are the cylinders arranged?
- They are horizontally opposed
Describe the PA-28-181 engine.
How is ignition provided?
- The starter is powered by the primary battery
- Press the starter
- Starter then engages the flywheel
- The flywheel starts turning the crankshaft which is directly driven
- Crankshaft begins to rotate the propeller
- Crankshaft also makes the magnetos begin to spin creating an electrical current
- Crankshaft begins to move the pistons which are located inside the cylinders that are rotating
- As the pistons are moving and providing power, the valves are opening.
- As the electrical current from the magneto travels to the spark plug it now emits a spark
- Which then ignites the fuel/air mixture
10.Then the four-stroke cycle begins in the cylinders (intake, compression, combustion, exhaust)
11.They are then rotating each of the four stroke cycle in each of the four cylinders keeping the engine running at a constant pace.
Describe the PA-28-181 engine.
What are the minimum and maximum oil capacities?
ATP Minimum….
- 6.5 Quarts
ATP Maximum….
- 8 Quarts
POH Minimum….
- 2 Quarts
POH Maximum….
- 8 Quarts
Describe the propeller system.
Who makes the propellers?
- Sensenich
- 76 Inch Diameter
- Metal Blade
Describe the propeller system.
How is the propeller RPM adjusted?
- Throttle
Describe the propeller system?
Define fixed pitch.
- Does not change
- A fixed pitch like ours, the RPM’s will not stay the same. They will get lower on takeoff and higher on landing. The RPM’s will change because our pitch won’t change.
*If pitch is adjustable and constant speed, the RPM’s will stay the same (NOT OURS)
Describe the electrical system.
- 28 DC volts for the electrical system
- 70 amps for the alternator
- We have two batteries in our planes
- 24 Lead Acid Battery for the primary battery
- 24 Lead Acid Battery for the emergency battery
