The most common wing de-ice system.
What is the inflatable boot de-ice system?
Name the most common anti-ice systems
What are thermal pneumatic, thermal electric, and chemical.
In what ways are ice detected?
What is visually, electronically (ice detector sensors), and audibly (icing conditions)
What do aircraft windshields have installed during manufacturing?
What is a hydrophobic coating.
How is a chemical deicing system used on propellers?
What is the glycol-based fluid being metered from a tank by a pump that slings the fluid onto the propeller hub.
After inflation of wing de-ice boots, what is used to deflate the air from the boot?
What is a vacuum Regulator?
Aircraft surfaces that anti-ice are used
What are the wings, windows, vertical stabilizer, and horizontal stabilizer.
Aircraft flight lift decreases, thrust decreases, weight increases, and drag increases.
What is the effects of icing in flight.
What does a chemical rain repellant achieve?
What is dissipation of rain water by spreading it out evenly in beads.
If snow or ice is collected on a propeller, how can it be removed?
What is move the aircraft into a warm hanger or use frost remover or de-icing fluid.
What is the function of the timer or control unit in a boot de-ice system?
What is control the action of the distributor valves to insure all boots are inflated in the proper sequence.
What source of anti-ice protection is used most commonly on wing leading edge slats?
What is bleed air from the engine compressor.
What are the (4) types of de-icing fluids and what color are each of them?
What is Type 1 color orange, Type 2 color white/pale yellow, Type 3 color unknown, and Type 4 color green.
What is a pneumatic rain removal system?
What is a system where heated air is jettison over the windshields to create a rain deterrent.
On a propeller in flight how are you able to see icing conditions?
What is looking at the tip of the spinner.
Which engine driven air pump uses oil to lubricate it's internal functions?
What is the wet-type engine driven air pump.
How is the WAI (Wing Anti-ice) systems monitored by the flight crew?
What is the aircraft onboard computer maintenance page using the WAI ACIPS systems.
What is HOT (Holdover Time)?
What is the time that is estimated that deicing/ anti-icing fluid prevents formation of frost or ice on aircraft surfaces.
Name the (3) vinyl plies associated with aircraft windshield construction?
What is the inner ply, the center ply, and the outer ply.
What are some of the effects on flight of an iced over propeller?
What is reduced torque and reduced flight functions.
What is the function of the oil separator in the wet-type engine driven air pump?
What is remove oil as the air flows and returns it to the engine through a drain line.

What is thermal electric anti-icing.
