NON-ATS SURVEILLANCE ROUTE
A route on which an aircraft can determine its position, track, and, consequently, the minimum IFR altitude without the benefit of ATS surveillance information
(note: this is a route that isn’t a vector, etc, its the flight planned route, or a route that pilots can fly without ATS surveillance assistance. A Surveillance ATC route is a vector, etc)
Why vector an aircraft?
sequencing - sequencing for terminal arrival
spacing - may be required by inter unit arrangement
separation - for conflict resolution
efficiency
pilot request
restricted airspace
traffic - pilot may request a vector around VFR traffic
What to consider before choosing to vector an aircraft
Controller Workload
Pilot Workload
Proximity of Aircraft to the Sector Boundary
VECTOR
A heading given by a controller to a pilot to provide navigational guidance
Vector an aircraft if any of following apply:
- It is necessary for separation.[4]
- It is required for noise abatement procedures.
- You or the aircraft will gain an operational advantage.
- The pilot requests it.
4 PTL, RBL, and PIV functions may be used to determine that a turn has been initiated.
If you initiate vectoring, inform the pilot of the following:
- The purpose of vectors and/or the point to which the aircraft is being vectored
VECTORS [DUE] TRAFFIC
VECTORS ( sequencing / spacing / other reason)
- That the aircraft’s SID or STAR is cancelled, if applicable
SID CANCELLED
STAR CANCELLED
If the aircraft is flying an open STAR, the pilot will be aware of the purpose of vectors, as the chart and the TC AIM provide this information. Providing distance to fly or expectations for descent will help pilots manage their profile appropriately.

(EXAMPLES)
Class G airspace is airspace that…
Class G airspace is airspace that has not been designated Class A, B, C, D, E or F, and within which ATC has neither the authority nor the responsibility to exercise control over air traffic.
However, ATS units do provide flight information and alerting services.
The alerting service will automatically alert SAR authorities once an aircraft becomes overdue, which is normally determined from data contained in the flight plan or flight itinerary.
In effect, Class G is all uncontrolled domestic airspace.
Low-level air routes are contained within Class G airspace. They are basically the same as a low-level airway, except that they extend upwards from the surface of the earth and are not controlled, and ATC separation is not provided to IFR or VFR aircraft. The lateral dimensions are identical to those of a low-level airway.
Before vectoring an aircraft, ensure…
Before vectoring an aircraft, ensure that it can be established on the cleared route without requiring navigation assistance while within ATS surveillance coverage.
HEADING
The direction in which the longitudinal axis of an aircraft is pointed, usually expressed in degrees from north (true, magnetic, compass, or grid north).
effect of wind on track
Vector an aircraft by specifying one of the following:
- The heading to be flown
FLY HEADING (number)
(LEAVE/DEPART) (fix) HEADING (number)
MAINTAIN PRESENT HEADING
- The direction of the turn and the heading to be flown after completion of the turn
TURN (LEFT/RIGHT) HEADING (number)
- The direction of the turn and the number of degrees to turn
TURN (LEFT/RIGHT) (number) DEGREES
When vectoring, ensure the following:
- Provide aircraft with adequate terrain clearance by assigning altitudes at or above a minimum IFR altitude specified for the area within which they are being vectored.
- Follow unit procedures to assign cold temperature corrected minimum IFR altitudes, if applicable.
Note: when vectored, pilots may be unable to determine their aircraft’s exact position
When an aircraft is at an established minimum vectoring altitude that does not provide adequate clearance above a prominent obstruction, vector the aircraft by one of the following minima:
- 5 miles, if the position of the obstruction is indicated on CSiT or NARDS
- 3 miles, if the following apply:
◦ You provide terminal control service.
◦ The ATS surveillance sources include MLAT/WAM, DND-NG, or RSE but do not include DND-NWS.
◦ CSiT or NARDS displays a maximum range of 120 miles from left to right.
◦ The obstruction is enclosed within a circular buffer that is indicated on CSiT or NARDS. (Vectoring an Aircraft Past an Obstruction)
(Note: The buffer must be displayed at the required ATS surveillance separation distance from the obstruction)
You may terminate vectoring of an aircraft, provided any of the following apply to the aircraft:
- It is cleared for an approach.
- It is cleared to hold.
- It is established on the cleared route without requiring navigation assistance.
(note: An aircraft that is on a track that will intercept “on course” within a reasonable distance is considered to be established on the cleared route)
