2) Altitude assignments
Transmit whole thousands:
By pronouncing each digit in the number of thousands followed by the word thousand. EX: 11,000 = One One Thousand
You MAY express altitude above sea level:
In thousands plus hundreds of feet, or using separate digits for flight levels.
EX: Two Thousand Seven Hundred
Flight Level Two Zero Zero
You may express aircraft flight numbers and aircraft type numbers:
In group form, provided there is no likelihood for misunderstanding
You may express wind speed, RVR data and cloud height:
Wind direction must be expressed as:
- In group form
- Seperate digits
EX: Wind Two Two Zero at 15
Thirty Five Hundred Broken
RVR Two Thousand Eight Hundred
The word "decimal" must be transmitted in the appropriate sequence with numbers except:
1) When transmitting altimeter settings
2) When transmitting VHF or UHF frequencies IF it is not likely to cause misunderstanding
How should altimeter settings be given?
1) Omit the decimal if desired
2) In inches of mercury to the nearest hundreth
3) each digit seperately
How should you issue wind: With an analog display? With a digital display?
Analog: to the nearest 10 degrees direction and 5 knots speed
Digital: the readout value
Time checks should be transmitted:
In hours and minutes UTC, unless otherwise specified, to the nearest half minute.
EX: Time Zero Seven One Five and a Half
Insert the aircraft ident at the beginning of ________ transmission, and __________, the unit identification as the second item of each transmission.
As required (needs to be there on at least initial contact)
When may you omit the name and function of the unit from a radio transmission?
1) The unit has been previously identified, AND
2) Only one function is being provided, AND
3) There is no likelihood of misunderstanding
Normally, ATC messages are transmitted using: For IFR and CVFR movement and control messages? For messages to aircraft concerning control and safety?
- ATC Interphone
- Air to ground communication
If the primary communication systems are congested or not available, use alternate communication as follows: For IFR and CVFR movement and control? For VFR and DVFR movement? and What other option?
IFR and CVFR - via the most expeditious means available
VFR and DVFR - ATC interphone
Other option - meteorological circuits
Do not release flight data regarding commercial airline flights, military flights, VIP flights, Transport and Nav Canada flights except:
To their respective agencies AND only through authorized channels
Read back verbatim IFR clearances or IFR instructions (or amendments to) if:
1) received from a canadian controller
2) requested by other agencies
Normally a pilot is required to read back all IFR clearances except:
1) If the clearance is received on the ground before departing from a controlled aerodrome and a SID is specified
2) The receipt of the air traffic control clearance is acknowledged by the pilot-in-command by electronic means
*FOR BOTH, UNLESS REQUESTED
The pilot in command is required to ______ and ______ all control instructions _______ and _______ by the pilot (unless it compromises flight safety)
1) Acknowledge and comply with
2) Directed to and received by
If you detect errors in a readback, you should:
1) Identify and correct any errors OR
2) Restate the clearance or instruction in full if there is any possibility of misunderstanding
Define: Air Traffic Control Clearance.
Pilots are required to?
1) An authorization issued by an ATC unit for an aircraft to proceed within controlled airspace in accordance with conditions specified by that unit.
2) Required to comply once accepted
Define: Air Traffic Control Instruction.
Pilots are required to?
1) A directive issued by an ATC unit for ATC purposes.
2) Required to comply if directed to and acknowledged (subject to aircraft safety at the pilots discretion)
An ATC clearance or instruction constitutes authority for an aircraft to proceed only in so far as _____________ is concerned, and is based solely on ________________.
- Known air traffic is concerned
- based solely on the need to safely expedite and separate air traffic
If amending a clearance route:
1) state the amendment, mentioning that the rest of the route is unchanged (rest of clearance/route unchanged) OR
2) Re-state the entire route
If amending a clearance altitude:
- State the altitude amendment, AND, IF REQUIRED
1) Restate any applicable altitude restrictions OR
2) State that applicable altitude restrictions are still in effect (previous altitude restrictions unchanged)
You may use the phrase "flight planned route" in a departure clearance provided:
1) The flight plan is not "air filed" AND
2) You are able to ensure the aircraft is established through radar or sufficient routing AND
3) The previously filed route has not been changed OR
4) If it has been changed: the change is clearly identifiable, the aircraft is advised that the clearance contains changes, AND the change is specified in the clearance
You may use the phrase "via centre stored flight planned route" provided:
1) The filed plan has been filed in accordance with a stored agreement
2) No changes have been made
You may use the phrase "via requested routing" provided:
1) The aircraft has given the detailed route description in its request AND
2) DCPC is used
You may clear an aircraft "via direct" provided:
The aircraft is at or above minimum IFR altitude for the controlled airspace in which the flight will operate
If it is necessary to clear an aircraft to a fix short of the destination airport AND if any part of the route beyond the clearance limit differs from the last assigned routing, you should:
Issue the route the aircraft may expect beyond the clearance limit
You may instruct an aircraft to follow a specified track or heading for a time, to a location, or to an altitude provided:
The instruction does not prevent the aircraft from clearing all obstructions and terrain in accordance with specified minimums.
In addition to stating the manufacturer or type, certain types of aircraft may state their generic type. These are:
