The ATC interphone system is designed to exchange ______ air traffic control messages.

IFR and CVFR

What are the 2 primary modes of operation for ATC Interphone?

Telephone (Landline) and Hotlines

The telephone mode works like a normal phone and must be answered by the controller ______.

when it rings

Hotlines link two units directly and allow for _______. For example, a hotline that connects Moncton Tower to Moncton ACC may be used ______ by the controllers in those two units.

each ACC, military and air carrier operational offices

If the following messages came simultaneously on the ATC Interphone, list the priority they would be given:

• IFR, CVFR, and SVFR movement and control messages

[Urgency messages], [IFR, CVFR, and SVFR movement and control messages], [Approval request messages concerning long-range IFR flight and altitude reservation messages]

What are the 1st and 2nd priorities on both ATC and AMIS interphone tables?

1. Distress messages (including ESCAT)

2. Urgency messages

Acccording to AMIS interphone priorities, what kind of messages are second in priority behind distress messages?

Urgency

What are the two methods of sharing lines?

Manual signalling, voice signalling

Manual signalling is completed using either a _____ that, when operated, actuates the signalling device at the office called.

push button, a key, or a dial

_______ units still commonly use manual signalling; _____ units use it less frequently.

FSS and FIC, ATC

With manual signalling, follow three steps:

1. Ensure that the line is not being used by asking LINE CLEAR?

2. ____________
   [The unit or sector answers by identifying themselves.]

3. Identify yourself and state your reason for calling

Key in a three-digit code to connect to the appropriate unit or sector

With voice signalling, follow three steps:

1. Ensure that the line is not being used by asking LINE CLEAR?

2. ____________
   [The unit or sector answers by identifying themselves.]

3. Identify yourself and state your reason for calling

Identify yourself and speak the name of the desired unit or sector

When interrupting a transmission to transmit a higher priority message, ATS personnel must first assess the _______, and use the words _____ to interrupt.

If a question of priority arises, who has operational jurisdiction?

ACC controllers

When terminating a call, make sure _____. Note that circuits may be connected manually by an operator at the communications station or automatically by dialing a _______.

the circuit is disconnected, “connect sequence”

There are 3 voice signalling steps when using an interphone. Are these steps in the correct order?

1. Ensure that the line is not being used by asking LINE CLEAR?

2. Identify yourself and speak the name of the desired unit or sector.

3. State your reason for calling.

Yes

Manual signalling or voice signalling are required when using shared lines on ATS internal telephones.

True

Certain ATS facilities have circuits that connect with counterparts in other countries. When communicating with foreign agencies, use _____.

the same rules as when communicating with Canadian ATS staff

What type of messages are transmitted via hotlines?

Brief control messages with a high level of immediacy

When using hotlines, follow these steps:

1. State the name of the sector or unit you are calling, followed by ______
   [The sector or unit being called answers by identifying themselves]

2. State your message.

your own sector or unit name and the reason for the call

Winnipeg Area Control Centre. You state the name of the unit you

are calling followed by your unit name. What do you do next?

State the reason for the call

Normally, only routine control messages with a low level of immediacy are transmitted via hotlines

False

You have just lost communication with an Air Canada flight

enroute to St John's. Your supervisor advises you to contact the

next closest aircraft to relay a message. ls this an appropriate way

to re-establish communication?

Yes, other aircraft can relay a message
