of airport runways and movement areas. This may be
accomplished via verbal means, flight progress strips,
other written information, or automation displays.

Question 6

List the coordination between LC and GC

Answer 6

Ground control must notify local control when a departing aircraft has been taxied to a runway other
than one previously designated as active.
Ground control must notify local control of any aircraft taxied to an intersection for takeoff. This
notification may be accomplished by verbal means or by flight progress strips.
When the runways in use for landing/departing aircraft are not visible from the tower or the aircraft
using them are not visible on radar, advise the local/ground controller of the aircraft’s location before releasing the aircraft to the other controller.

“(Item) APPEAR/S (observed condition)”

Question 10

Who is responsible for scanning the runways, and what is GC responsibility?
