Gyro Basics
This spinning component is the heart of a gyroscope.
What is a rotor?
This property describes a gyro’s ability to maintain its spin axis in a fixed direction.
What is rigidity?
This gyro-based instrument provides pitch and roll information to pilots.
What is the artificial horizon?
The two types of gyro wonder are real and ___.
What is apparent wonder?
The Earth rotates at this rate per hour.
15 degrees
The axis around which the rotor spins is called this.
what is the spin axis?
This property causes a gyro to react at 90 degrees to an applied force.
What is precession?
A directional gyro is often used in this aircraft navigation system.
What is an inertial navigation system?
This type of wonder is caused by manufacturing imperfections or wear.
What is real wonder?
The formula for apparent drift due to Earth rate is ___.
What is 15 × sin(latitude) in degrees per hour?
$300: A gyroscope can be classified as horizontal or vertical based on this
What is the spin axis orientation?
Increasing the mass, diameter, or speed of a rotor increases this property.
What is rigidity?
This indicator combines a turn and slip indicator with a rate-of-roll gyro.
What is the turn coordinator?
This type of wonder results from Earth's rotation or movement across latitudes.
What is apparent wonder?
The formula for apparent topple due to Earth rate is ___.
What is 15 × cos(latitude) in degrees per hour?
This structure allows a gyroscope to maintain its orientation in space.
What is a gimbal?
Precession and rigidity have this type of relationship.
What is an inverse relationship?
Gyros are used in autopilot systems to provide this function.
What is stability/control?
When the spin axis moves in a vertical plane, this type of movement occurs.
What is topple?
The formula for transport wonder is ___.
What is (easterly ground speed ÷ 60) × tan(latitude) in degrees per hour?
A two-gimbal system allows a gyro to have this many degrees of freedom.
What is 2?
The speed of precession is directly proportional to force and inversely proportional to these two factors.
What are mass and rotational speed?
A gyromagnetic compass combines a traditional compass with this type of stabilizing system.
What is a gyro?
This force affects a gyro’s orientation because meridians converge toward the poles.
What is earth rate?
At the equator, apparent drift due to Earth rate is ___.
What is zero?
