Aircraft Systems • 1
SECTION 1
Aircraft Systems
Engine
The Archer is equipped with a Lycoming, 4-cylinder, O-360 (opposed, 360 cubic
inch) engine rated at 180 horsepower at 2700 RPM. The engine is direct drive
(crankshaft connected directly to the propeller), horizontally opposed (pistons
oppose each other), piston driven, carbureted and normally aspirated (no turbo
or supercharging). Engine ignition is provided through the use of two engine-
driven magnetos, which are independent of the aircraft's electrical system and
each other.

HHorizontally Opposed
AAir Cooled
NNormally Aspirated
DDirect Drive
Carburetor Icing
Under certain atmospheric conditions at temperatures of 20° to 70° F
(-5° to 20° C), it is possible for ice to form in the induction system, even in
summer weather. This is due to the high air velocity through the carburetor
venturi and the absorption of heat from this air by vaporization of the fuel. To
avoid this, carburetor heat is provided to replace the heat lost by vaporization.
The initial signs of carburetor ice can include engine roughness and a drop in
RPM. Carburetor heat should be selected on full if carburetor ice is encountered.
Adjust mixture for maximum smoothness.
Note: Partial carburetor heat may be worse than no heat at all, since it may melt
part of the ice, which will refreeze in the intake system. Therefore when using
carburetor heat, always use full heat and when the ice is removed, return the
control to the full cold position.

2 • Aircraft Systems
From the Archer POH, in regards to carburetor heat usage during approach:
"Carburetor heat should not be applied unless there is an indication of carburetor
icing, since the use of carburetor heat causes a reduction in power which may be
critical in case of a go-around. Full throttle operation with carburetor heat on can
cause detonation."
Oil
Acceptable range for oil in the Archer is 6–8 quarts. Never depart with the oil
indicating below 6 quarts.
ATP policy states any time a full quart of oil can be added to the
Archer oil system, a full quart should be added. Never add less
than a full quart.
Propeller
The Archer is equipped with a Sensenich two-bladed, xed pitch, metal
propeller. Propeller diameter is 76 inches. Maximum RPM (red line) is 2700 RPM.
Landing Gear
The landing gear is a xed, 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.
Brakes
The Archer is equipped with hydraulically actuated disc brakes on the main
landing gear wheels. Braking is accomplished by depressing the tops of the
rudder pedals. Both toe brakes and the parking brake have separate braking
cylinders, but share a hydraulic reservoir. The brake uid reservoir is installed
on the top left front face of the rewall. To set the parking brake, pull back on
the brake lever, depressing the knob attached to the left side of the handle,
then release the brake lever. To disengage the parking brake, pull back on the
brake lever to disengage the catch mechanism, then allow the handle to swing
forward.
The parking brake is not to be used in training or ight checks
with ATP.

Aircraft Systems • 3
Flaps
The Archer is equipped with a manual ap system. The aps are extended with
a lever located between the two pilot seats. Flap settings are 0°, 10°, 25°, and 40°,
and are spring-loaded to return to the 0 ° position.
ATP operations require aps 25° for all landings except:
• Short and soft eld, aps 40°
• Precision approach, aps 10°
Pitot Static
Pitot and static pressure are both received from a pitot head installed on the
bottom of the left wing. An alternate static source is located inside the cabin
under the left side of the instrument panel, for use in the event of static port
blockage. When using the alternate static source, the storm window and cabin
vents must be closed and the cabin heater and defroster must be on. This will
reduce the pressure dierential between the cockpit and the atmosphere,
reducing pitot-static error. The pitot-static instruments are the airspeed
indicator, altimeter, and vertical speed indicator.
Both the pitot and static lines can be drained through separate drain valves
located on the left lower side of the fuselage interior.
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 takeos and landings, and when switching tanks.
ATP uses the electric fuel pump for in-ight maneuvers, except
for steep turns.
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 ight 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 o
5. Check fuel pressure

4 • Aircraft Systems
An electric engine priming system is provided to facilitate starting. The primer
switch is located on the far left side of the overhead switch panel.
CAUTION: DO NOT OVER-PRIME. Over-priming washes lubrication
from cylinder walls and increases re risk. Always follow the
checklist for primer usage.
Fuel Management
Throughout operation, checklists will call for "Fuel Selector... Proper Tank." It is
important to monitor fuel burn to maintain a balanced fuel load. The Archer
POH does not provide a limitation on fuel imbalance. It is ATP's policy that
the fuel selector should not be changed during critical phases of ight, to
include takeo and operations below pattern altitude, unless called for on an
emergency checklist.
During cruise ight and maneuvers, fuel load should be monitored and the fuel
selector should be selected to the fullest tank only when a noticeable dierence
in fuel load occurs. 30 minutes of operation should result in a fuel load
dierence of several gallons, and is a good guideline for fuel selector changes.
During pattern work operations, the fuel selector should only be changed while
on the ground during a Full Stop/Taxi Back procedure. It is critical to follow the
proper procedure for changing fuel tanks while on the ground, as well as while
in ight. Failure to follow the proper fuel selector change procedure can lead to
interruption in fuel ow, and engine failure, during a critical phase of ight.
Electrical System
The Archer is equipped with a 28-volt DC electrical system and a 24-volt lead-
acid 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.
Alternator Failure
In the case of the "ALTERNATOR INOP" annunciator, follow the "ALT Annunciator
Illuminated" checklist. The expanded procedure can be found in the Archer POH
Section 3.25:
"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. The

Aircraft Systems • 5
electrical load should be reduced as much as possible. Check the alternator circuit
breakers for a popped circuit.
The next step is to attempt to reset the overvoltage relay. This is accomplished by
moving the ALT switch to OFF for one second and then to ON. If the trouble was
caused by a momentary overvoltage condition (30.5 volts and up) this procedure
should return the ammeter to a normal reading.
Note: Low Bus Voltage Annunciator will be illuminated.
If the ammeter continues to indicate "0" output, or if the alternator will not remain
reset, turn o the ALT switch, maintain minimum electrical load, and land as soon
as practical. Anticipate complete electrical failure. Duration of battery power will be
dependent on electrical load and battery condition prior to failure."
The battery is used as a source of emergency electrical power and for engine
starts. High drain items include the lights, vent fan, heater, radios, and PFD/MFD.
If an electrical problem arises, always check circuit breakers. If a circuit breaker is
popped, reset only one time.
CAUTION: Do not reset popped circuit breakers if smoke can be
smelled.
Other electrical components include the standby attitude indicator, the starter,
the electric fuel pump, electric engine primer, the stall warning horn, the
ammeter, and the annunciator panel.
Garmin G500
The Archer is equipped with the Garmin G500 electronic ight deck. The G500
powers on with the battery master switch.

G500 Components
The G500 is comprised of six main components:
• Primary Flight Display (PFD, left) and
Multi-Function Display (MFD, right)
• Attitude Heading Reference System (AHRS)
• Air Data Computer (ADC)
• Magnetometer
• Temperature Probe
• Dual Garmin GNS 430 GPS
The PFD (left) shows primary ight information in place of traditional pitot-
static and gyroscopic instruments, and also provides an HSI for navigation. ATP
procedures call for conguring the MFD (right) to display trac information.
The Attitude Heading Reference System (AHRS) contains tilt sensors,
accelerometers, and rate sensors to provide attitude and heading information
on the PFD.
The Air Data Computer (ADC) compiles information from the pitot-static system
and an outside air temperature sensor to provide pressure altitude, airspeed,
vertical speed, and outside air temperature on the PFD.
The magnetometer senses the earth's magnetic eld and sends data to the
AHRS for processing to determine magnetic heading.
The temperature probe provides outside air temperature (OAT) data to the ADC.
The dual Garmin GNS 430 GPSs provide input to the AHRS and PFD/MFD.
CAUTION: The GNS 430 and G500 units each have their own
databases. Navigation, terrain and map information on the G500
Multi-Function Display (MFD) may not be current and is not to be
used for navigation. Use the G500 MFD for trac information.
