Alternative to rudder-controlled gear assembly. - ANS_Castering
Slang for fixed main gear. - ANS_Down and Welded
Name of fuel tank drain and tool - ANS_Sump drain; fuel strainer
Which instrument(s) will become inoperative if the static vents become clogged? - ANS_Altimeter, Airspeed, Vertical Speed Indicator
Which instrument will become inoperative if the pitot tube becomes clogged? - ANS_Airspeed.
What are the two types of Stall Warning devices? - ANS_Suction and electrical
What do a vented fuel cap or tank vent lines prevent? - ANS_A vacuum being created, which would reduce, and even eventually stop, fuel from flowing.
Why does the crankcase need a breather tube? - ANS_Combustion gasses and water vapor eventually start leaking past the piston/piston rings, so it needs a pressure relief. On its way through the crankcase, the hot gas picks up oil and carries it out the crankcase breather (where it gets sprayed on the bottom of your clean, beautiful airplane).
Why should you check that the crankcase breather tube is not clogged? - ANS_The amount of oil exiting through the crankcase breather increases with engine age. As the oil flow increases, it starts to
carbonize inside the hot exhaust, and more significantly, where the breather line attaches to the exhaust stack.
This carbon deposit will eventually close the vent path, increasing internal crankcase pressure to the point that the gasses will find an alternative way out—usually by blowing out the front crankshaft seal, or sometimes the oil pan gasket.
Most of these "alternate vents" will dump the engine oil overboard very rapidly.
If it's the crank seal that goes, you'll get oil on the windshield right away—a lot.
Other leaks will dump the oil out the lower cowling, making the oil pressure, or perhaps the oil temperature if you're really alert, the first indication of a serious problem.
What is the empennage? - ANS_The tail, and it has fixed and movable parts, Fixed are the vertical and horizontal stabilizers. Movable appendages are the elevator and rudder.
What is a stabilator? - ANS_A combo of the horizontal stabilizer and an elevator. The entire horizontal surface moves as a single unit.
What is the main purpose of the propeller spinner? - ANS_To deflect air into the intake sections of the cowling to cool air-cooled engines.
Acronym: VOR - ANS_Very High frequency Omnidirectional Range
Slang for analog flight instruments - ANS_Steam gauges
What are the four essential instruments? - ANS_Airspeed, Attitude, Altimeter, Magnetic Compass
What are the left and right screens called in a glass cockpit? - ANS_Left: PFD, Primary Flight Display, uses solid-state technology
Right: MFD, Multi-function Display, uses computer-generated engine instruments, checklists, weather, GPS info, etc.
