NAV 1 Week 7 Quiz Gyro Compass

Which of the following is a limitation of the gyro compass?

• Subject to deviation

• Requires constant electrical power

• Cannot integrate with radar

• Not used on ships above 500 GT

In case of gyro failure, which equipment ensures compliance with SOLAS?

• Radar

• Echo sounder

• Magnetic compass

• Autopilot

Why is the gyrosphere suspended within gimbals?

• To allow free movement on three axes

• To reduce weight of rotor

• To improve visibility

• To stabilize repeater output

How does precession differ from inertia in gyro operation?

• Precession resists force, inertia applies correction

• Precession causes axis movement, inertia resists change

• Precession keeps plane fixed, inertia redirects axis

• Precession aligns to meridian, inertia traces spiral

Why are repeater compasses located on bridge wings?

• For redundancy

• To assist in taking bearings

• To reduce vibration

• To support autopilot

The gyro compass output can directly control which of the following?

• Autopilot

• Weather radar

• VHF communication

• GPS signal

A course recorder connected to the gyro compass is used for:

• Emergency navigation

• Continuous course logging

• Correcting latitude error

• Updating GPS input

Why is a constant electrical supply critical for gyro compasses?

• To keep mercury ballistics active

• To maintain rotor speed

• To prevent repeater misalignment

• To reduce ship vibrations

The gyro repeater located at the helm primarily assists in:

• Recording courses

• Steering the vessel

• Aligning radars

• Detecting variation

Why must repeaters be regularly checked against the master compass?

• To avoid duplication

• To correct electrical supply

• To maintain alignment

• To ensure quick damping
