What is the purpose of an integrator circuit?
To calculate velocity and distance
What is the result of integrating acceleration?
Velocity
What determines the direction of the pendulum's swing?
The direction of acceleration
What is the sensitive axis of an accelerometer?
The axis of maximum sensitivity
What is the primary purpose of using four or more satellites in GPS systems?
To improve the accuracy of the system and provide precise altitude information
What is the constant speed used in GPS calculations?
300 000 000 metres per second
What is the primary reason for using atomic clocks in GPS satellites?
To provide accurate timing for signal emission
Why is it not feasible to have atomic clocks in GPS receivers?
Due to the high cost of atomic clocks
What is the minimum number of satellites required for GPS calculations, if the receiver's altitude is known?
Three satellites
What is the principle used by GPS systems to determine the location of the receiver?
Three-dimensional trilateration
What is the primary reason for correct orientation of the RADALT antenna?
To produce a directional radiated beam
What happens when the receiver-transmitter is in the transmit mode?
The receiver is disabled to prevent interference
What is the purpose of the decision height (DH) annunciator on the RADALT indicator?
To alert the pilot when the selected height is breached
What is the typical mounting arrangement for RADALT systems in use today?
Rack-mounted units
What happens if the radar altitude is lost for a short period of time?
The receiver-transmitter will continue to search for a period before energizing a fail flag on the indicator
What is the purpose of the arrows marked on the RADALT antenna?
To show the correct orientation of the antenna
What is the range of an NDB with a daylight range of 600 miles over the sea, when located over unfavourable types of land?
100 miles
What can cause a change in bearing indications in mountainous areas?
Reflection from the mountains
What is the method of overcoming station interference?
Using a receiver with high adjacent channel rejection ratio
What type of interference occurs when an aircraft is near a thunderstorm?
Static interference
Why does an NDB's range vary greatly in different directions when located on the coastline?
Due to the difference in environment over land and sea
What type of wave can an NDB receive in mountainous areas?
Both direct and reflected waves
