What is the maximum demonstrated crosswind component?
17 KTS
- Describe the PA-28-181 engine.
a. How many cylinders?
b. Who is the manufacturer?
c. What is the horsepower rating?
d. Does it have fuel injectors or a carburetor?
e. Is the engine turbo-charged or normally aspirated?
f. How are the cylinders arranged?
g. How is ignition provided?
h. What are the minimum and maximum oil capacities?
The Piper Archer is equipped with a Lycoming 4 cylinder O-360 engine (Lycoming is the manufacturer, it’s got 4 cylinders, the O stands for opposed and 360 is the total engine displacement in cubic inches). The engine is rated at 180 horse power at 2700 RPM. The engine is also direct drive which means the crankshaft is connected directly to the propeller, it is carbureted which means it has a carburetor which is the induction system in charge of the fuel/air mixture. The engine is normally aspirated that means that it is not super charged or turbo charged, the engine is also air cooled. Ignition is provided through the use of two engine-driven magnetos, which are independent of the aircraft’s electrical system and each other. Each magneto powers one spark plug per cylinder (for redundancy and more complete combustion) for a total of 8 spark plugs. The oil capacities are 8 quarts max and 2 quarts minimum according to the POH but per ATP policies, the minimum before each flight is 6.5 quarts.
Describe the propeller system
a. Who makes the propellers?
b. How is propeller RPM adjusted?
c. Define fixed pitch.
The Piper Archer is equipped with a Sensenich two-bladed , fixed-pitch, metal propeller. The propeller diameter is 76 inches, the maximum RPM is 2700 RPM. The propeller RPM is directly adjusted by the engine throttle lever. This is a fixed pitch propeller which means the pitch of the blades cannot be adjusted by the pilot or during flight operations therefore the speed of the propeller is directly related to the engine’s speed.
Describe the electrical system
The Archer is equipped with a 28-volt DC electrical system and a 24-volt lead acid main battery. (Archers with Garmin G1000 avionics also have an isolated 24-volt emergency battery.) Electrical power is supplied by a 70-amp, engine driven alternator. A voltage regulator maintains a constant 28-volt output from the alternator. For Archers with G1000 avionics, electrical system parameters may be viewed on the
Engine Indication System display on the MFD
What are the indications of a failed alternator?
There are a few indications of a failed alternator:
-An ALTR FAIL CAS message on the PDF screen
-Discharge indication on an ammeter or in this case in G1000 avionics we can see that on the MFD screen on the alternator output
-A battery discharge warning light or indicator on the instrument panel
-A gradual or sudden loss of electrical power to instruments, avionics, and other electrically powered systems
-The aircraft’s voltmeter or ammeter may show abnormal readings
-Interior and exterior lights may dim or flicker as the battery begins to drain without being recharged by the alternator
-Communication and navigation equipment may experience disruptions or complete failures due to insufficient electrical power.
Will the engine continue to run with the alternator and battery master switches turned off?
Yes, the engine will continue to run with both the alternator and battery master switches turned off. This is because the engine’s ignition system relies on magnetos, which are independent of the aircraft’s electrical system.
Describe the stall warning system
The Archer is equipped with an electric stall detector located on the leading edge of the left wing. The stall warning horn is activated between 5 and 10 knots above stall speed. In G1000 Archers, the warning is an aural annunciation (“Stall… Stall… Stall…”).
Describe the fuel system
The Archer, which uses 100 low lead avgas (blue), is equipped with two 25 gallon fuel tanks. One gallon is unusable in each tank. There is one engine-driven and one electrically-driven fuel pump. The electric fuel pump is used for all takeoffs and landings, and when switching tanks.
Describe how to switch tanks in cruise flight
The correct procedure for switching tanks in cruise flight is:
- Electric fuel pump on
- Fuel selector from “L” to “R” or from “R” to “L”
- Check fuel pressure
- Electric fuel pump off
- Check fuel pressure
Describe the landing gear system
The landing gear is a fixed, tricycle-type gear, with oleo (air/oil) struts providing shock absorption for all three wheels. The nose wheel contains a shimmy dampener, which damps nose wheel vibrations during ground operations and centers the nose wheel in the air. The nose wheel is linked to the rudder pedals by a steering mechanism which turns the nosewheel up to 20° each side of center
What is the type of braking system used by the Piper Archer?
The Piper Archer has disc brakes on the main wheels, operated hydraulically. To brake, you press the top of the rudder pedals. Both the toe brakes (used with the pedals) and the parking brake have separate brake cylinders but share the same hydraulic fluid reservoir, which is located on the top left front of the firewall.
What type of flaps does the archer have?
The Piper Archer is equipped with manually-operated slotted flaps. These flaps are controlled by a flap handle located between the two front seats. The flaps can be extended to three different positions: 10 degrees, 25 degrees, and 40 degrees
What are the maximum takeoff, taxi, and landing weights?
Max Takeoff weight: 2558lbs
Max Taxi Weight: 2550lbs
Max Landing Weight: 2550lbs
What is the maximum baggage weight?V
Baggage 200 lbs. Max
