Unit 9 - Quiz 2

____________________________ is a pressure sensor that you use to measure the aircraft’s altitude.

• A barometer
• An accelerometer
• A magnetometer
• A gyroscope

Global Positioning Systems (GPS) use the signals sent by a number of satellites in orbit around the earth _____________________________________________________.

• to transmit the pilot’s commands to the aircraft
• in order to determine their specific geographic location
• so that the battery will utilize more amperage when going slow
• in order to read the proper barometric pressure

The Follow-Me feature offered by some manufacturers should be used with caution because _________________________________________________________.

• most sUAVs need to be powered down before using it
• it quickly eats up battery power
• most sUAVs do not yet have “Sense-and-Avoid” technology, and a drone could fly right into a tree or other overhang while trying to follow the user.
• large propellers cause sUAVs to unexpectedly hover

An IMU works by detecting the current rate of acceleration using one or more accelerometers, and also detects changes in rotational attributes like pitch, roll and yaw using one or more gyroscopes.

• True
• False

Dead Reckoning (DR) is based on mathematical calculations to determine one’s current position by using a previously determined position, and advancing that position based upon known or estimated speeds over elapsed time and course.

• True
• False

______________________________allows a drone to fly on its own according to pre-planned destination points that were configured into the drone’s navigational software.

• The Inertial Measurement Unit (IMU)
• Signal triangulation
• Waypoint navigation
• A gimbal

Waypoints are sets of coordinates that identify a point in physical space. For air navigation, these coordinates include ____________________________________.

• longitude, latitude, and altitude
• roll, pitch, and yaw
• thrust, weight, and balance

A field of regard (FOR) is a virtual perimeter that identifies boundaries around an area that normally has been designated as a “no-fly” zone, such as airports, infrastructure facilities (power plants), or military installations.

• True
• False

Open source software usually does not allow the user to modify the software code itself.

• True
• False

The field of view is the angular cone perceivable by the sensor at a particular time-instant.

• True
• False
