What is the main purpose of the Interphone System?
To exchange IFR and CVFR control messages
What are the 2 primary modes of operation of the Interphone System?
- Hotline
- Allows for immediate controller to controller communication
- Used for high priority messages
- Used for Radar hand-offs
- Phone/Land line
- Must be answered by controller when it rings
- Works like normal phone
What are the 2 methods for making calls on the Interphone
- Manual (Dial-in or button press)
- Voice signalling (By speaking into the headset)
What words must you use to bump someone of a cicuit for a higher priority message?
“Emergency”
or
“Control”
ATC Interphone
IFR Control messages
Priorities
Except for emergency communication, use the ATC interphone system only for the transmission of messages related to the control or safety of aircraft as listed in the following order of priority:
A. Distress messages (including ESCAT).
B. Urgency messages.
C. IFR, CVFR, and SVFR, movement and control messages.
D. CIRVIS messages.
E. Search and rescue messages.
F. Communications search messages.
G. DVFR AND VFR movement messages, including flight itinerary messages.
H. Approval request messages concerning long-range IFR flight and altitude reservation
messages.
I. ESCAT Test Message.
J. Messages concerning the malfunctioning of NAVAIDs.
AMIS Interphone
VFR and DVFR movement messages
Co-ordinate the use of the AMIS interphone system with ATOS for the transmission of messages relating to the control or safety of aircraft as listed in the following order of priority:

What is the IFR clearance mnemonic?
List the sequence to conform to for an IFR clearance.
PACSRAMDST
- Prefix (ATC clears)
- Aircraft ID
- Clearance limit (to CYXE)
- SID
- Route
- Altitude
- Mach number
- Departure, en route, approach or holding instructions
- Special instructions or info
- Traffic information
How to relay an IFR clearance
- Aircraft ID
- Unit ID
- “IFR CLEARANCE” (wait for aircraft to indicate it is ready to copy) * “ATC CLEARS” then the clearance verbatim, as received from the IFR unit.
Example:
- Tower: UAL220, Montreal Tower, IFR clearance.
- UAL220: Montreal tower, UAL220 ready to copy
- Tower: ATC clears UAL220 to the Winnipeg airport ………………..
Whose responsibility is it to transmit the clearance to the aircraft?
It is the responsibility of the communication agency to which the clearance was issued to realy it to the aircraft immediately upon receipt.
If not delivered in 3 minutes the controller must be notified.
What options does a controller have if the clearance was not delivered within 3 minutes?
Instruct agency to:
- To continue attempting to deliver and to report if undelivered by a specified time.
- To attempt to deliver at a specified time.
- To cancel the clearance.
Explain the following clearance validation
CV ACA213 ON
Clearance valid when ACA213 lands and is on the taxiway
Explain the following clearance validation
CV 1634
Clearance valid at 16:34
Explain the following clearance validation
CVR
Clearance validation required
Explain the following clearance validation
CV ACA213 +5
Clearance valid when ACA213 is airborne + 5 minutes
Explain the following clearance validation
CV WJA105 +5 CC 1640
Clearance valid when WJA105 is airborne + 5 minutes
Clearance cancelled at 16:40
When is a readback not necessary?
- When no changes made to originally filed flight plan
- When the clearance is issued from a machine printed strip
- When there is no apparent misunderstanding of the clearance
- When the are no alternate instructions in the clearance
- When the clearance includes a published SID
How to amend and IFR clearance
Cross off wrong instruction
Enter new instruction with initials
