What is the maximum demonstrated crosswind component?
17 KIAS
How many cylinders does the PA-28-181 engine have?
4 cylinders
Who manufactures the PA-28-181 engine?
Lycoming
What is the horsepower rating for the PA-28-181 engine?
180 horsepower
Does the PA-28-181 engine have fuel injector or a carburetor?
Carburetor
Is the PA-28-181 engine fuel injected or normally aspirated?
Normally Aspirated
How are the cylinders arranged?
Horizontally opposed (Pistons oppose each other)
How is ignition provided?
Engine ignition is provided through the use of engine driven magnetos, which are independent of the aircrafts electrical system and each other.
What are the minimum and maximum oil capacities?
Never below 6 quarts and never above 8 quarts
Describe the propeller system
Who makes the propeller?
How is propeller RPM adjusted?
Define fixed pitch.
The Archer III is equipped with a Sensenich two-bladed, fixed pitch metal propeller. Propeller diameter is 76 inches. Maximum RPM (red line) is 2700 RPM.
RPM is adjusted through use of the throttle.
A fixed pitch prop cannot be adjusted or changed. It has one pitch, which is usually a compromise between speed and power.
Describe the Electrical System
The Archer III is equipped with a 28-volt DC electrical system and a 24-volt battery. Electrical power is supplied by a 70-amp, engine-driven alternator. A voltage regulator maintains a constant 28-volt output from the alternator. An overvoltage relay is located on the forward left side of the fuselage behind the instrument panel. Alternator output is displayed on a digital ammeter on the
instrument panel.
What are the indications of a failed alternator?
The “ALTERNATOR INOP” will illuminate.
Loss of alternator output is detected through zero reading on the ammeter. Before executing the following procedure, ensure that the reading is zero and not merely low by actuating an electrically powered device, such as the landing light. If no increase in the ammeter reading is noted, alternator failure can be assumed.
Electrical load should be kept at minimum and check for popped alternator circuit breaker.
Will the engines continue to run with the alternator and battery master switches off?
Yes, through the use of magnetos. However you will be flying dark.
Describe the stall warning system
The Archer III is equipped with an electric stall detector located on the leading edge of the left wing. The stall horn emits a continuous sound and is activated between 5 and 10 knots above stall speed.
Describe the fuel system
The Archer III, 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.
Explain how to change fuel tanks in cruise flight
The aircraft is equipped with a three-position fuel selector control. The positions are “L”, “R”, and “OFF”.
The correct procedure for switching tanks in cruise flight is:
1. Electric fuel pump on
2. Fuel selector from “L” to “R” or from “R” to “L”
3. Check fuel pressure
4. Electric fuel pump off
5. 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.
How is steering accomplished on the ground?
The nose wheel is linked to the rudder pedals
by a steering mechanism which turns the nose up to 20 degrees each side of center.
What is the range of travel on the nose wheel?
20 degrees each side of center
