A

same frequency

21
Q

What creates a difference of frequency between two beams?

A

Q

Give at least three disadvantages of auto pilot

A
  • Automation – induced failures
  • False alarms
  • Boredom
  • Over-reliance, complacency; willing to accept results without scrutinizing them first

Q

pilot’s main role

A

maneuver the airplane from A to B safely and efficiently

30
Q

Give at least three from the five sub-tasks of a pilot

A
