203A+204A - Lighting/Conflict Resolution

What is the phraseology used by a pilot that indicates traffic is resolved and no traffic should be passed?

A-B-C HAS THE [aircraft] IN SIGHT

What phraseology would you listen for that would indicate the traffic is NOT resolved?

A-B-C IS LOOKING, A-B-C ROGER

What is the one exception regarding passing traffic to an aircraft that has reported another in sight?

An aircraft is preparing to depart and plans to enter the runway ahead of traffic that they have reported in sight. Update MUST be given

What generally is a good habit to apply to your AAS when passing traffic?

Request a position report from the aircraft

What is some phraseology you can use in order to assist pilots in conflict resolution?

“DO YOU HAVE TRAFFIC IN SIGHT?”

“WHAT ARE YOU INTENTIONS?”

“(traffic update) CAN YOU (proposed course of action)”

“REQUEST YOU (plan for conflict resolution)”

Define a Traffic Update as per MATS:

Any item of traffic information issued by ATS to pilots after the initial advisory or previous update.

What is a good rule of thumb to apply when asking pilots “CONFIRM YOU HAVE TRAFFIC IN SIGHT?”

Aircraft are less than 5NM apart and both have been given a traffic update

What is the “rule of two” used at March?

• 2 Minutes apart

• Within 20 degrees of eachother (Nose-Nose)

• Aircraft in the vicinity are within 2000 feet of eachother

What are the two requirements to meet the definition of a conflict?

1. The aircraft are in such proximity to each other that,

2. One of the aircraft may require an immediate alteration to its flight path to avoid creating a risk of collision

Regarding position reports and “ping-ponging” traffic updates, what should be considered?

Ensuring you have not given both aircraft the same reporting point

As per the MATS, what would be some situations that would warrant “CAN YOU” phraseology for traffic movement?

• Established procedures do not resolve the conflict

• Visual contact is established, but does resolve conflict

• It is request by the pilot

• It is clear you are NOT controlling the aircrafts movement

• You deem it necessary because the pilots plan has not resolved the conflict

• You judge it necessary to avoid immediate conflict

What are the three priority of tasks as defined in MATS for Task Planning and Monitoring?

1. Emergencies

2. Inflight services

3. Preflight Services

Recall from CARS 609.19, if two aircraft are converging at the same altitude and opposing tracks and there is risk of collision, what is the correct course of action?

The aircraft that has the other on its right will give right of way

Recall from CARS 609.19, in a situation where one aircraft is being overtaken by another, which aircraft shall give right of way?

The overtaking aircraft will give way. The overtaking aircraft will pass to the right 

Recall from CARS 609.19, where an aircraft is in flight or maneuvering on the surface while another is landing or about to land, who gives right of way?

The aircraft in flight/Aircraft maneuvering on the surface gives way

Recall from CARS 609.19, where two aircraft are approaching the airport for landing, which aircraft gives way? The lower altitude or the higher altitude aircraft?

Higher aircraft gives way to the lower aircraft

Recall from CARS 609.19, before taking off or landing, what shall an aircraft confirm?

There is no risk of collision and the airport is suitable for operation

In what cases should you not use the “clock method” for relaying traffic information?

• High wind situations

• Traffic is not visually ascertained (Specialist cannot see traffic outside or on the situation display)

Who has the responsibility for traffic avoidance? The specialist or the pilot?

The Pilot

What is the flight service specialists responsibility in a situation that has the potential for a conflict?

1. Identify the conflict

2. Pass traffic to the appropriate aircraft

3. Confirm the pilots have obtained “TRAFFIC IN SIGHT”

4. Monitor the situation to ensure conflict is avoided

How far away are runway lights spaced from one-another?

200 feet maximum

What does ARCAL stand for?

Aircraft RadioControl of Aerodrome Lighting

What are the 3 settings for ARCAL(K) lighting?

3, 5, 7

When does ARCAL lighting turn off?

15 minutes after activation

As per MATS, when are runway edge lights expected to be turned on?

• At night or daytime IMC

• At least 5 minutes before the ETA (Turn on when aircraft calls after AAS)

As per MATS, when are runway edge lights expected to be turned off?

• At least 3 minutes after departure

• Turn off when clear of runway

When shall the VASIS be turned on?

• At least 5 minutes before the ETA (Turn on when aircraft calls after AAS)

• Turn off when clear of the runway or once landed
  

At March, what is generally considered a good daytime VASIS intensity for RWY09/27 and 14/32?

4-5 for RWY 09/27 and 2-3 for RWY 14/32

What is considered daytime IMC?

• Ceiling less than 1000 feet or;

• Visibility is 3 miles or less

What are the rules regarding wind sock placement at an aerodrome?

• Runways more than 4000ft:

  • At each end of RWY

  • 500 ft from RWY end 200 feet outward

• Runways 4000ft or less:

  • Centrally 4000 ft
