Tower positions

In direct communication with the aircraft (LC or GC)

Tower associate positions

Local assist, ground assist, local associate, or ground associate

Tower cab coordinator position

(CC) commonly referred to as coordinator

Flight data

(FD) flight data

Clearance delivery

(CD) commonly referred to as coordinator

Main duties of local control (LC)

-Separating aircraft on the same and intersecting runways including arrivals and departures
-issuing landing and takeoff clearance
-wake turbulence separation standards are maintained
-resolving emergency and special situations
-coordinate with ground for

Main duties of ground control (GC)

-separation of aircraft and vehicles operating on the ramp, taxiways, and inactive runways
-aircraft taxing for takeoff
-aircraft taxiing in after landing
-ground vehicles operating on airport movement areas
-excludes areas solely reserved for vehicular t

Main duties of clearance deliver and flight data (CD & FD)

-process and forward flight plan info
-utilize alphanumerics
-assist tower CAB in meeting situation objectives

Main duties of clearance deliver (CD)

-operate communications equipment
-issue clearances and ensure accuracy of pilot read back
-operate tower equipment
-issuing clearances to departing aircraft

Main duties of flight data (FD)

-operate interphones
-compile statistical data
-observe and report weather info
-receiving and relaying IFR departure clearances to the CD controller
-operate flight data processing equipment
-relaying weather and NOTAM info to other positions
-collecting

Anticipated separation

(Tower/LC)
Takeoff clearance needs not to be withheld until prescribed separation exists if there is a reasonable assurance it will exist when the aircraft starts takeoff roll

Takeoff roll

An aircraft is aligned with the runway centerline and the aircraft is moving with the intent to take off

Clear of the runway

When all parts of the aircraft are beyond runway edge lines (hold bars) and no restrictions to its continued movement

CAT 1

Small aircraft (12,500 pounds or less) with a single propellor driven engine and all helicopters

CAT 2

Small aircraft (12,500 pounds or less) with propellor driven twin engines

CAT 3

All other aircraft including super

Departure behind preceding departure

Any time of day

CAT 1 preceded by CAT 1 or CAT 2 (Departure behind preceding departure)

3,000 feet

CAT 2 preceded by CAT 1 or 2 (Departure behind preceding departure)

4,500 feet

All categories preceded by CAT 3 (Departure behind preceding departure)

6,000 feet

Departure behind a preceding arrival

Cannot use SRS separation at any time and arrival must be clear of the runway

Arrival behind a preceding arrival

-Only between sunset and sunrise
-only between CAT 1 and 2 aircraft
-measure at the time the second aircraft crosses the landing threshold

CAT 1 landing behind CAT 1 or 2 (Arrival behind a preceding arrival)

3,000 feet

CAT 2 landing behind CAT 1 or 2 (Arrival behind a preceding arrival)

4,500 feet

Arrival behind a preceding departure

-any time of day
-all SRS CATs
-measured at the time the second aircraft crosses the landing threshold

CAT 1 behind CAT 1 or 2 (Arrival behind a preceding departure)

3,000 feet

CAT 2 behind CAT 1 or 2 (Arrival behind a preceding departure)

4,500 feet

When either is a CAT 3 aircraft (arrival behind a preceding departure)

6,000 feet

Small aircraft

Max certified takeoff weight of 41,000 pounds or less
(Small+ is greater than 12,500 up to 41,000)

Large aircraft

Between 41,000 pounds and 300,000 pounds

Heavy and super aircraft

Greater than or equal to 300,000 pounds

Intent of line up and wait

LUAW
-to position an aircraft for an imminent departure
-not to be used if an aircraft will be holding on the runway for any lengthy period of time
-controller must explicitly issue the clearance while advising the holding aircraft of the operation
-keepi

Phraseology of LUAW

Aircraft ID, runway (number), LUAW (traffic info)

Full stop

LC issues runway exiting instructuons

Touch and Go

Considered an arrival until touchdown then considered a departure

Stop and Go

Arrival until full stop hen departure

Low approach

Considered an arrival until crossing the landing threshold and then considered a departure

Go around

Issued prior to the aircraft crossing the landing threshold
-Used to ensure same runway separation is maintained

Land and hold short operations

-special procedures need to be established
-pilots may refuse to participate

Traffic pattern segment

Upwind, crosswind, downwind, base, final

Wake turbulence

-By-product of lift
-high pressure below wing and low pressure above

ATC wake turbulence separation

Heavy" and "super" in communications

Movement areas

Runways, taxiways, and intersections(where ground control must coordinate with local control)

Non-movement areas

Ramps (not usually controlled by GC)
