Section 1:
Objective: ADFComplete statements concerning dead reckoning and automatic direction finders (ADF) as aids to dead reckoning
Level II Technician Rating
ADF Tracking
ADF is used for “homing”Needle only points TO the stationNicknamed “Bird Dog”Curved course in winds if not corrected
Level II Technician Rating
Check for Understanding
The determination of the position of an aircraft using information including the course flown, distance traveled, and drift is called ________________.Dead Reckoning
Level II Technician Rating
Check for Understanding
One foundation of navigation is finding the position based on time, speed, and ____________.direction
Level II Technician Rating

Level II Technician Rating
Check for Understanding
What is the advantage of VOR over ADF during bad weather?
VOR signals are relatively free of weather disturbances.
Level II Technician Rating
Check for Understanding
In flying using VOR, what method is used to verify the source of a frequency that has been selected for use in navigation?
Identify the source station by voice ID or morse code. If
unable to do so, do not use the signal.
