mpass Rose - A small circle graduated in 360 increments, to show direction expressed in degrees.
Most airports have a compass rose, which is a series of lines marked out on a ramp or maintenance run up area where there is no magnetic interference. Lines, oriented to magnetic north, are painted every 30° which is used to perform a "Compass Swing".
FAA Advisory Circular 43.13-1B contains guidance regarding the performance of Compass Swings:
A COMPASS SWING must be performed whenever any ferrous component of the system (i.e. flux valve compensator, or Standby Compass) is installed, removed, repaired, or a new compass is installed. The magnetic compass can be checked for accuracy by using a compass rose located on an airport. The compass swing is normally effected by placing the aircraft on various magnetic headings and comparing the deviations with those on the deviation cards. Refer to CFR14, 23.1327, 14 CFR 23.1547, and the equipment or aircraft manufacturer's manual.
A compass swing must be performed on the following occasions:
NOTE: For conventional gear aircraft, the mechanic will have to position the magnetic compass in the straight and level position or mount the tail of the aircraft on a moveable dolly to simulate a straight and level cruise configuration. Remember the hairline sight compass is only intended to be used as a general piece of test equipment.
NOTE: A common error that affects the compass' accuracy is the mounting of a compass or instruments on or in the instrument panel using steel machine screws/nuts rather than brass hardware, magnetized control yoke, structural tubing, and improperly routed electrical wiring, which can cause unreasonable compass error.
Standby (wet) Compass. Adjustment and compensation of the Standby Compass may also be accomplished by using the "compass swing" method.

A Flux Valve is a magnetic sensory device that electrically transmits information to an aircraft's compass system regarding its orientation relative to Earth's magnetic field. This information, in the form of three separate electrical signals tied to a common return, is used to generate a visual indication to the flight crew regarding the heading of the aircraft relative to magnetic north.

Trying to keep oscillations of the compass at a minimum, the mass of the magnetic assembly is kept as close as possible to the suspension needle. There are also compasses with damping wires.
No. The components of a vector will change based on what coordinate system is used to express that vector.
Different aircraft have different brands of avionics, but the C-17 and C-5 aircraft have Honeywell avionics.

Battleships are no longer used in modern warfare. They have been replaced by the aircraft carrier support group.
The tail has many components that guide the aircraft, make it go up or down and often contains the APU.
