Day 2 Flashcards
TRUE/FALSE: You can use separation based on radio navaids for VFR operations.
TRUE. MATS 10.1.3.3
N.B: Do not apply time standards to VFR flights that require the use of radio navaids to determine position.
TRUE/FALSE: You may use the pilot’s in-flight advice of approval status in the application of separation.
TRUE: MATS 10.1.3.5
What are the conditions of T8a - 15 minutes AT the crossing point?
a) Each aircraft has either an approved SCNS or MNPS (Minimum Navigation Performance Specifications);
b) Ground speeds are a minimum of 300 kt; and
c) Separation exists when there is at least 15 min between estimates at the intersection of the tracks.
What are the conditions of T8b - 15 min, FROM the crossing point?
a) Each aircraft has either an approved SCNS or MNPS (Minimum Navigation Performance Specifications);
b) Ground speeds are a minimum of 300 kt; and
c) Vertical separation must exist:
i) from 15 min prior to the estimate for B at the intersection; and
ii) until 15 min after A has passed the intersection.
What is the definition of Mach Number Technique?
The technique of clearing successive jet aircraft operating along the
same track to maintain specified Mach numbers in order to maintain
longitudinal separation.
What are the Mach Number Technique general conditions?
When applying Mach number technique:
a) only apply between jet aircraft with approved SCNS;
b) do not assign a block level clearance;
c) use a common point, defined as:
i) a geographical point on the aircraft’s track over which both aircraft will
fly; or
ii) a point along the individual track of each aircraft which is equidistant
from the geographical point described in ‘i)’; and
d) base application on the requirement that the last assigned Mach number will be
maintained at all times, including during any climbs or descents
What are the general conditions of D2?
Distance information is provided by:
a) DME; or
b) GNSS in CTA only, by RNP2 or RNP4
approved aircraft.
When may you use GNSS for the standards D1-D4?
In CTA only, GNSS distance information may be provided by RNP2 or RNP4 approved
aircraft for the application of standards D1 to D4, subject to the following conditions:
a) where a mix of GNSS and DME distances is used, do not use distance reports if
one aircraft is within 20 NM of the reference point; and
b) when GNSS is used by both aircraft, you must apply the standard with
reference to published waypoints.
When is a DME Beacon considered to be co-sited with a waypoint or navaid?
Consider a DME beacon to be co-sited with a waypoint or the azimuth navaid
providing tracking guidance, when the DME site is located within 600 metres of the
waypoint or azimuth navaid.
When can you use an off-track waypoint for a same-direction distance standard?
When applying same direction distance separation, you may use an off-track
waypoint or beacon provided that the distance reports from both aircraft are together
increasing or decreasing.
When may closing speeds exist between aircraft?
Closing speed between aircraft may exist, provided that:
a) separation is in excess of the minimum distance required;
b) distance checks are made at intervals not exceeding 15 min; and
c) when aircraft are cruising at levels not vertically separated, the closing speed is
not greater than 35 kt IAS or Mach 0.06.
What are common definite pass standards?
R2 - 20NM
R5 - 50NM
D8a - 10NM (12NM above 180 DME)
D8b - 5NM
T6b - 10 minutes/15minutes after time of passing
T7a - Opposite sides of a navaid
T7b - Opposite sides of a visual fix
T7c - Sight and Pass
T7d - Surveillance Passing
Can you use CPDLC to maintain a distance standard, and what conditions should these meet?
For distance reports obtained by CPDLC, check to ensure the reports have been
sent:
a) from both aircraft at the same time; or
b) from the leading aircraft first.
