1
Q

What is the longitudinal separation minima, based on distance, which applies between aircraft climbing and descending on reciprocal tracks?

A

D10 - positively established the aircraft has passed each other by at least 10NM as determined by:

  • the same on-track DME station, or
  • and on-track DME station and co-located waypoint, or
  • the same waypoint

This standard need not apply when it is confirmed the aircraft have passed each other by:

  • both aircraft reported passing same exact reporting point, or
  • mutual sighting, no possibility of incorrect identification, or
  • another separation standard

Q

When shall separation be increased?

A

Whenever circumstances call for extra precautions e.g:

  • requested by a pilot or considered necessary by the controller
  • a pilot reports severe turbulence or mountain wave activity, or the aircraft is known to be entering an area of severe turbulence or mountain wave activity
  • the navigational accuracy of an aircraft may be impaired
  • failure of a navaid reduces the capacity for frequent determination of position and speed
  • the aircraft is experiencing communications failure
  • the aircraft’s performance is abnormal
  • the aircraft is being subjected to unlawful interference

Q

How is longitudinal separation based on time established?

A

By requiring an aircraft to:

  • depart at a specified time, or
  • lose or gain time to arrive over a location at a specified time, or
  • hold over a location until a specified time

Q

What is longitudinal separation based on distance subject to?

A
  • direct pilot/controller VHF communications maintain
  • the aircraft are flying directly inbound to or outbound from the same DME station and/or co-located waypoint
  • when applying these minima between GNSS equipped aircraft the controller shall specifically request a GNSS derived distance
  • the aircraft to which GNSS derived distance applies specifies “G” in item 10 of the flight plan

Q

Name the various longitudinal separation criteria based on time between two aircraft at the same level on the same track.

A
  • OCAT15
  • T10 if navaids permit frequent determination of position and speed
  • T5 providing the preceding aircraft is maintaining 20kts or more faster than the following:
    • between aircraft departed from the same aerodrome
    • between en-route aircraft that have reported over the same exact reporting point
    • between an en-route and a departing aircraft, if the en-route aircraft reports over an exact reporting point 5 minutes before the time the departing aircraft joins the route
  • T3 in the above cases if the preceding aircraft maintains 40kts or more faster than the following

Q

What are the general restrictions on the use of D20 and D10 when applying longitudinal separation based on distance using DME?

A
  • D20 valid for any altitude
  • D10 valid up to and including F290, provided both aircraft are on the same side of a DME station
  • D10 valid up to and including F150 when aircraft are on opposite sides of a DME station

Q

What is the minimum longitudinal separation based on distance between aircraft at the same level on the same track?

A

D20, or
D10 if the leading aircraft is 20kts or more faster, and
- each aircraft utilizes:
- the same on track DME station, or
- an on-track DME station and co-located waypoint, or
- the same waypoint
- separation is checked by obtaining simultaneous DME/GNSS readings at frequent intervals to ensure the minimum is established and not infringed

Q

What is the minimum longitudinal distance between two aircraft climbing and descending on the same track?

A

D20 provided:

  • each aircraft utilizes:
    • the same on-track DME station, or
    • an on-track DME station and co-located waypoint, or
    • the same waypoint
  • separation is checked at frequent intervals by obtaining simultaneous DME/GNSS readings

D10 as above provided:

  • the leading aircraft maintains 20kts or more faster than the following aircraft, or
  • one aircraft maintains level flight while vertical separation does not exist, or
  • the succeeding aircraft is instructed to reach separation level D10 prior to the last DME or GNSS distance report of the preceding aircraft

Q

What should essential traffic information include?

A
  • the words “ESSENTIAL TRAFFIC”
  • direction of flight
  • type of aircraft
  • level information
  • position information
17
Q

When may an area controller apply visual separation beyond the vicinity of the aerodrome?

A

In class C & D airspace during the hours of daylight provided that:

  • a specific request is made by a pilot
  • each aircraft is under the control of the same or physically adjacent operating positions
  • there is no possibility of incorrect identification

The pilots are required to ensure that:

  • both flights remain in VMC, and
  • each aircraft is continuously visible to the pilot of the other aircraft and both pilots agree to the application of visual separation, or
  • the pilot of the following aircraft reports having the succeeding in sight and can maintain visual separation
18
Q

What is the horizontal and vertical separation criteria between controlled flights and danger or restricted areas established for aircraft operating IMC & SVFR?

A

5NM and 1000ft (2000ft above F290)

19
Q

What is the horizontal and vertical separation criteria between controlled flights and military operational areas?

A

For aircraft activity: 5NM and 1000ft (2000ft above F290)

For non-aircraft activity: kept clear

20
Q

What are the vertical and horizontal separation criteria required from an aircraft dumping fuel?

A
  • 10NM horizontally
  • 50NM or 15 minutes flying time behind
  • 1000ft above (2000ft above F290)
