Q

What is the process in maintaining positive coordination and control? If an aircraft wishes to cross the runway what must happen? What does this include? What is the correct phraseology?

A

Ground control must obtain approval from local control before authorizing an aircraft or vehicle to cross or use any portion of an active runway.
This coordination is must include point/intersection at the runway where the operation will occur.
Phraseology:” cross (runway) AT (point/intersection).”

Q

What if LC initiates the coordination?

A

LC can initiate the coordination. For example: Runway 28 right crossing observed. It is still the responsibility for GC to reply with runway 28 right crossing complete.

Q

If there is need for authorization for traffic to proceed on an active runway, for purposes other then crossing, what is required?

Q

what are three type of coordination between LC and GC? Hint: exchange info, no visibility, diff type of communication

A
  1. LC and GC must exchange information as necessary for the safe and efficient use of airport runways and movement areas.
  2. When runways are not visible from the tower or on radar, LC must advise GC of the aircraft’s location before releasing the aircraft to the GC
    frequency.
  3. Coordination may be accomplished via verbal means, flight progress
    strips, other written information, or automated displays.

Q

What is the responsibility of GC and LC in relation to monitoring runways?

A

LC and GC continuously scan areas to ensure that the runway is free of all vehicles, equipment, and personnel before departing aircraft starts take off roll or landing aircraft crossed the runway threshold.

Q

When utilizing Certified Tower Radar Display (CTRD), you may issue traffic advisories to radar-identified aircraft by using standard radar phraseology that includes the following: hint: 4

A
  1. azimuth from aircraft in terms of 12- hour clock
    When rapidly maneuvering aircraft , specify the direction from the aircraft position in reference to the eight direction compass (n,ne,e,se,s,sw,w,and nw)
  2. distance from aircraft in miles
  3. direction in which traffic is proceeding and/or relative movement of traffic
  4. if known, type of aircraft and altitude

18
Q

What is required for using CTRD?

A

CTRD can only be used with radar identified aircraft only and to be used by a radar-certified controller

19
Q

What must be determined prior to issuing the taxi instructions or takeoff clearance?

A

Determine the aircraft position

20
Q

How can the aircrafts position be determined?

A

visually by the controller, by pilots or through the use of ASDE

21
Q

When can you not issue a line up and wait at an intersection? Hint: 3 things

A
  1. between sunset and sunrise unless restrictions are met
  2. at any time when an intersection is not visible from the tower
  3. when inbound aircraft has been cleared to land on the respective runway
22
Q

When would you inform an aircraft of any observed abnormal aircraft condition?

A

when requested by the pilot or you deem it necessary

23
Q

What would be the phraseology to inform an aircraft of abnormal aircraft condition?

A

item appears (observed condition)

24
Q

in reference to surface area restrictions:
if traffic conditions permit, approve a pilots request to?
Hint :2 items

A

cross c or d surface areas

exceed airspace speed limit

25
Q

in reference to surface area restrictions:

What two things would you not approve

A

do not approve speed in excess of 250kt unless the pilot informs you that a higher min speed is required for the performance of the aircraft.
do not approve a pilot’s request or ask a pilot to conduct unusual maneuvers if they are not essential to the performance of the flight

26
Q 
light signals:
steady green
green flashes 
steady red 
red flashes 
white flashes
red and green
A

steady green- cleared for take off / cleared to land
green flashes - cleared to taxi / return for landing
steady red - stop. give way to other aircraft
red flashes- taxi clear of runway / airport unsafe
white flashes- return to starting point on airport
(ground only)
red and green- use extreme caution

27
Q

When radio signal cannot be employed, what is the backup method. What is the purpose of this back up method?

A

ATC lights signals is a back method used to control aircraft and the movement of vehicles, equipment, and personnel on movement areas when radio communication cannot be employed

28
Q

In the event that light gun signals are not effective, what other means of communication would you use?

A

relays by other aircraft/vehicles or broadcasting over the VORTAC

29
Q

In reference to light signals and obtaining acknowledgment from a receiver-only equipped aircraft, what request would you make for fixed wing aircraft and helicopters?

A

fixed-wing aircraft
- between sunrise and sunset:
- move ailerons or rudders while on the ground
- rock wings while in flight
helicopters
-between sunset and sunrise
- while hovering, either turn the helicopter toward the
tower and flash the landing light or rock the tip-path
plane (rotor blade path)
-while in flight, either flash the landing light or rock
the tip-path plane.
-flash landing light or search light

30
Q

what does tip-path plane mean?

A

refers to the movement of the main rotor blade, accomplished via moving the cyclic. movement of the tip-path plane is much like a fixed-wing aircraft rocking its wings

31
Q

What is the standard direction of turns in the traffic pattern?

A

to the left

32
Q

What is a nonstandard direction of turns?

A

to the right

33
Q

When may left and right traffic pattern be permitted for use?

A

permitted to use for parallel runways

34
Q

What are the pattern legs? hint:6

A

upwind- flight path parallel to the landing runway in the direction of landing
crosswind leg- flight path at right angles to the landing runway off its takeoff end
downwind leg- flight path parallel to the landing runway in the opposite direction of landing
base leg- flight path at right angles to the landing runway off its approach and extending from the downwind leg to the intersection of the extended runway centerline
final approach- flight path in the direction of landing along the extended runway centerline from the base leg to the runway
departure leg- flight path that begins after takeoff and continues straight ahead along the extended runway centerline

35
Q

Regarding local procedures what do you need to issue prior to take off?

A

beacon code and appropriate departure frequency

36
Q

When can you omit the departure control frequency?

A

when the pilot has been or will be assigned a departure procedure and the departure frequency is published on the DP

37
Q

What is the proper phraseology for the departure frequency?

A

departure frequency (frequency, squawk (code).

38
Q

what type of military aircraft do you request to change departure control frequency?

A

departing IFR military turpoprop/turbojet aircraft

39
Q

where do you transmit urgent instructions?

A

departure frequency override

emergency frequency

40
Q

After take off, What aircraft are you responsible to instruct to contact departure control about 1/2 mile beyond the runway end?

A

instruct civil aircraft, military transport, and cargo types to contact departure control

41
Q

What do you not want to instruct to departing military turboprop/turbojet aircraft (except transport and cargo types)?

A

to make radio frequency or radar beacon changes before the aircraft reaches 2,500 feet above the surface.

42
Q

In regards to nonapproach control towers that are not equipped with tower radar display, what authorization are they given for appropriate separation between consecutive departures?
How about departures and arrivals?

A
  • based upon time or diverging courses

- the agreement has been approved by the area director of terminal operations

43
Q

provided that further communication with the controller is not required, when is a departing IFR civil aircraft instructed to contact departure control?

A

1/2 mile beyond the runway edge

44
Q

the LC position is in direct communication with the aircraft and ensures separation of aircraft

A
  • in the designated airspace

- on the runways
