What type of current is produced by a battery? Direct Current
True or False. The magnetos are a part of the electrical system. False, magnetos are completely separate from the electrical system.
What are four characteristics of hydraulic fluid that must be considered? Viscosity, Chemical Stability, Flash Point, Fire Point
________ is the temperature at which liquid gives off enough vapor to ignite momentarily. ________ is the temperature at which liquid gives off enough vapor to ignite and continue to burn. Flash Point, Fire Point
Name three types of hydraulic fluid. Vegetable-base, Mineral-base, Synthetic
What is the main purpose of circuit breakers or fuses? Protect various components from overloads.
If a circuit breaker pops out, you can reset it ______ time(s) One

What tread is used for light aircraft, grass runways and locations where breaking is only used as an aid to taxiing? Smooth tread.
What is a fusible plug used for? To prevent tire blowout due to heat build-up.
What are the five requirements needed for aircraft hydraulic fluid? Must flow with minimum opposition, must be incompressible, must have good lubricating properties, must inhibit corrosion and not attack seals, and must not foam during operation.
What is Flash Point? Ignition momentarily
What is Fire Point? Ignites, and keeps burning
When inspecting the brakes, what should you be sure to check? All the brake pads
When you check the brake rotor, what should you look for? Excessive rust, grooves, and the overall thickness
