What is the main duty of Clearance Delivery?
Give clearances to aircraft, amended as necessary
What are the main duties of Ground?
Ensure safety of taxiways and inactive runways, give taxi instructions
What are the main duties of Local?
Runway separation, sequencing arrivals and departures
What are the 3 types of approach control strips?
Departure
Arrival
Overflight
What word does Ground never use?

Twin engine prop less than 12,500 pounds
What is a category III aircraft?
Any aircraft that is not a Category I or II
What category are ALL helicopters in?
Category I
What is the minimum runway separation for departing aircraft by category?
I behind I or II 3000 feet
II behind I or II 4500 feet
III front or back 6000 feet
What is the minimum runway separation for landing aircraft by category?
I behind I or II 3000 feet
II behind I or II 4500 feet
III front or back entire runway
What are the restrictions that apply to using reduced runway separation by category
Must be visible landmarks
Only daylight hours
How do you separate departing and/or arriving aircraft using crossing runways?
I have listed 4 ways.
1) Have one clear the intersection before the second is cleared for takeoff or crosses the threshold to land.
2) Have one turn away from the intersection before the second is (see above)
3) Have one cleared to exit taxiway before intersection
4) Have one cleared to hold short of the intersection
What are the five legs of the traffic pattern?
Upwind Crosswind Downwind Base Final (Straight in)
What are some ways to space aircraft going into the traffic pattern?
I have listed 9.
1) Extend downwind
2) Extend upwind
3) Enter pattern at a specific point
4) Make L/R 360
5) Make L/R 270
6) Speeds
7) Land long
8) Land short
9) Follow another aircraft
What is the phrase to have an aircraft not land, but stay in the pattern?
Go around
What is the default direction of turn on a go around?
Left
What are the phrases used to have an aircraft:
1) stop
2) get on the runway and not take off
3) takeoff
1) hold position
2) line up and wait
3) cleared for takeoff
Besides cleared to land, what are the 4 other types of clearances can the tower give arriving aircraft?
Touch & go
Low approach
Stop & go
Option
At what wind speed do we use the calm wind runway?
Less than 5 knots, or
4 knots or less
What are the 3 types of taxis for helicopters, and what altitudes do they entail?
Ground taxi - on the ground
Hover taxi - up to 50 feet
Air taxi - up to 100 feet
When is wake turbulence the worst?
When an aircraft is low and slow
What causes wake turbulence?
Lift on the wings
At what speed do the wake turbulence vortices spread?
2-3 knots
How far down do the wake turbulence vortices sink?
500-900 feet
What are the 3 weight categories for aircraft and what weights are they classified by?
Small up to 41,000 pounds
Large 41,000 up to 255,000 pounds
Heavy over 255,000 pounds
What letter is before the type aircraft identifier of a heavy aircraft?
H
What is the time delay for any departure behind a B757 or heavy aircraft?
2 minutes
What is the time delay for a departure of any aircraft behind a heavy, or a small behind a large for an intersection or opposite direction departure?
3 minutes
What are the mileages required for wake turbulence separation by weight category for arriving aircraft?
Small behind large 4 miles Large/heavy behind B757 4 miles Small behind B757 5 miles Heavy behind heavy 4 miles Large behind heavy 5 miles Small behind heavy 6 miles
