Question

What are the five ROLL NAV sources?

Answer 1

The five ROLL NAV sources in engineering are radar altimeters, onboard inertial navigation systems (INS), global navigation satellite systems (GNSS), airspeed indicators, and data from navigation beacons.

Step-by-step explanation:

The five ROLL NAV sources in engineering are:

1. Radar Altimeters: These instruments use radar waves to measure the distance between an aircraft and the ground surface below, helping in navigation.
2. Onboard Inertial Navigation Systems (INS): INS uses accelerometers and gyroscopes to continuously track the position, velocity, and attitude of an aircraft.
3. Global Navigation Satellite Systems (GNSS): GNSS systems like GPS provide accurate positioning and timing information to aircraft.
4. Airspeed Indicators: These instruments measure the speed at which an aircraft is traveling through the air.
5. Data from Navigation Beacons: Navigation beacons transmit signals to aircraft that can be used to determine their position.
