Oral Flashcards
What kind of wings does the archer have?
Semi-tapered wings
LHAND
Lycoming IO-360-B4A, horizontally opposed, air cooled, naturally aspirated, direct drive.
What is the archers horsepower and rpm rating?
180 horsepower at 2700 rpm, lowest 500 rpm
How does the fuel injector work?
Based on the principle of differential pressure which balances air pressure against fuel pressure. The servo valve establishes the regulated fuel pressure and balances it with air pressure. Then the fuel flow divider distributes the fuel to each cylinder.
The PFD displays…
Airspeed, attitude, altitude, and heading (ADAHRS) information.
The MFD displays…
Engine information, maps, and traffic.
How many gallons of fuel can the archer hold? How much is usable?
Two 25 gallon tanks, 24 gallons usable. 17 gallons at tabs.
What is the minimum fuel grade for the archer?
100 or 100 LL
What kind of fuel sensor does the archer have?
One float type fuel sensor in each wing.

Takeoffs, landings, and when switching tanks.
What kind of fuel pumps does the archer have?
Electric and engine driven.
How many volts is the archers electrical system?
28 volts, DC (direct current).
How many volts/amps is the primary battery?
24 volts, 13.6 amps
How many amps and volts is the alternator?
70 amp, 28 volts
How many volts/amps is the emergency battery?
24 volts, 13.6 amps
What does the primary battery do?
Provides electrical power to equipment for engine starting and when engine is not running. It must be removed when charging from an external source.
How does the alternator work?
It is belt driven directly from the engine. Once the engine is running and the alternator switch is turned on, it becomes the primary source of electricity. The batteries are charged by the alternator in order to back it up in case of an alternator failure.
What does a voltage regulator do?
Regulates the electrical system to 28 volts, if it exceeds 32 volts it removes the alternator.
What does the emergency battery do?
Provides electrical power to emergency bus (standbys, PFD, nav/com 1, audio panel) for 30 minutes.
What is included in the essential bus?
Pitot heat, fuel pump, standbys, audio panel, ADAHRS, com/nav 1, GEA, PFD, transponder, and lighting.
What is included in the non essential bus?
Pitch trim, air conditioning, and vent fan.
What is included in the hot battery bus?
Courtesy lights, hour meter, and ELT.
How does the alternate static source work?
Uses cabin air for static pressure. Since the cabin air pressure is lower, all the instruments will read high.
Blocked pitot tube?
Airspeed indicator reads like an altimeter.
Blocked static port?
Altimeter and vertical airspeed indicator don’t work.
How do the cabin and windshield defroster get heat?
Shroud around the exhaust. If there is a leak in the muffler you could potentially get carbon monoxide poisoning.
How many degrees Celsius do you lose for every 1000 ft gained?
-2 C per 1000 ft gained.
What is a sealed cabin?
Oxygen is circulated and filtered. Used for high altitude and space flight.
What is a pressurized cabin?
Ambient air is forced into the cabin.
What is cabin differential pressure?
The difference between the air pressure inside the cabin and the air pressure outside the cabin.
What are the requirements of a pressurized cabin?
Air tight seal, cabin structure, source of compressed air, temperature and pressure regulation.
What are 3 sources of pressurization?
Turbocharger, supercharger, and an engine driven compressor.
What does a turbine engine do?
Compresses large amounts of air to be mixed with fuel and burned (jet pump, turbo compressor, air cycle machine).
What is isobaric control?
Maintains set cabin altitude.
What is differential control?
Constant differential pressure is kept by controlling cabin pressure to maintain a specific pressure difference between the cabin air and outside air.
What does the pressure controller do?
You can set it for cabin altitude, rate of cabin change, and barometric pressure settings. It sends a signal to the regulator outflow valves to control the pressure inside the cabin. It’s modes include automatic, manual, dump, and emergency smoke removal.
What is gradual decompression?
Loss of pressurization over a long period of time. Causes ears to pop and mild hypoxia. Masks drop at 14,000 ft. The most dangerous type of decompression.
What is rapid decompression?
Loss of pressurization suddenly and without warning.
What is explosive decompression?
Total loss of pressurization in less than 1 second.
How does pressurization work?
Ambient air goes through a compressor, as the air is compressed it heats up rapidly. The heated air is sent through a cooling unit, like a fuel-air heat exchanger then released into the cabin through ducts. A series of outflow valves regulate how quickly air is released into the cabin. Air comes into the cabin quicker than it is released, creating a high pressure environment.
At what altitude do you start to experience physiological effects?
Over 10,000 ft.
Define hypoxic
Inadequate supply of oxygen.
Define histotoxic
Blood is unable to take in oxygen due to alcohol or drugs.
Define hypemic
Blood is unable to carry oxygen due to smoking or carbon monoxide poisoning.
Define stagnant hypoxia
Oxygen deficiency in blood resulting from poor circulation (coronary artery disease).
