5L10 Complex Arrivals Flashcards
We rarely force a runway change once the arrival is inside the TCA due to:
High workload placed on flight crews by short notice runway changes
E.2.1 TWR Runway Selection. TWR must:
- Select DAR/DDRs in consultation with TCU;
- Ensure operational requirements for noise abatement and preferential runways are met when selecting DAR/DDRs or Runway Pairings;
- Only designate a DAR2/DDR2 Runway when conditions permit as per MATS
- Display DAR/DDRs in operational systems; (X)
- Coordinate verbally with TCU any changes to displayed DAR/DDRs, or runway availability;
- When practical, provide TCU with minimum 20 minutes prior notice of intent to change to Noise Abatement Runway Pairing
E.2.2 The Runway Pairings are:
- DAR/DDR 36 and 31 (Normal Hours)
- DAR/DDR 18 and 13 (Normal Hours)
- DAR 13 with DDR 36 (Noise Abatement)
- DAR 18 with DDR 31 (Noise Abatement)
E.2.3 Runway ______ is the preferred DAR1 if Runway 18 is DDR1, and weather conditions are below 1 SM visibility and/or 500’ ceiling.
13
E.2.4 During Normal Hours / 0700 - 2300L:
- Runway 36 is the preferred DAR1/DDR1
- Assign a Normal Hours Runway Pairing when operational conditions permit:
o Weekdays from 0700L to 1900L;
o Weekends when requested by TCU;
o Other times, when requested by either unit.
E.4.2 If a Runway Pairing is not assigned, other runways may be used provided:
- Traffic, workload, and operational conditions permit;
- Approval has been obtained as specified in E.4.3; (X)
- Same-direction flow is maintained :
o On weekdays, during normal Runway Pairing hours;
o Any other time that a TCU Departure position is open.
E.4.3 For Runway Use and Approval,
E.4.3.1 TWR must :
- Acknowledge paired arrival runway changes as soon as practical; (X)
- Approve non-paired arrival runway requests as soon as practical; (X)
E.4.1 Priority flights and declared operational requirements are _________
Exempt from any arrival and departure runway use restrictions
E.7.2 TWR must: (3)
E.7.2.1 Coordinate electronically their intended VFR sequence.
E.7.2.2 Verbally coordinate with TCU when additional ad-hoc spacing is required to accommodate TWR traffic or satisfy the condition in E.7.2.3.
E.7.2.3 Ensure Wake Turbulence Separation is maintained when sequencing TWR controlled aircraft ahead of TCU arrivals.
-Verbally coordinate with TCU if unable to approve a requested runway
Advantages of leaving an aircraft on the STAR (3)
- Predictability for both you and the aircraft
- Efficiency. STARs put the aircraft in the best position to begin the approach, and with fewer transmissions, than we can with vectors.
- Fuel efficiency
Advantages of using vectors over leaving aircraft on the STAR (2)
- Simplicity. Aircraft simply has to fly the assigned heading so there are fewer questions and less unexpected behavior.
- Ubiquity. Every aircraft has the ability to fly headings.
Two main reasons to make the straighter in aircraft #1 in the sequence
- It is easier- the only option to add track miles to the straight in aircraft is S-turns, which are a lot of work.
- If it does not work, we have more options- it is easier to widen out a base leg in case plan A doesn’t work.
Why does the CARs speed limit regulations exist? (2)
- Reduces the likelihood of collision with VFR aircraft.
- Lessens the possible damage from a bird strike.
Minimum speeds 20 miles or more from destination
Above 10 000- 250 IAS
Below 10 0000 210 IAS
Minimum speeds less than 20 miles from destination
Turbojet- 160 IAS (150 IAS only when required for spacing on final)
Propeller- 120 IAS
Maximum speed below 10 000 ft
250 knots
Maximum speed below 3000 ft AGL within 10 NM of a controlled aerodrome
200 knots (IAS)
Factors affecting speed performance (3)
- Wind
- Company limitations- different companies will fly the same aircraft at different speeds.
- Weather conditions- the worse the weather, the slower aircraft will go on final. Exception is icing as aircraft may speed up to minimize time in the icing areas.
Steps for cancelling an approach clearance (5)
- Cancel #2’s approach clearance well in advance of losing separation
- Scan for traffic, then issue heading and altitude assignments
- After the readback, inform the pilot of the reason for pulling them off and what to expect
- Coordinate with CYWG Tower
- Vector for another approach
The terminal controller may clear a pilot to conduct an instrument approach while another aircraft simultaneously conducts an instrument approach, provided:
- The ATS surveillance sources include MLAT/WAM, DND-NG, or RSE but do not include DND-NWS.
- The operation is conducted in accordance with a unit directive or arrangement.
- The pilots are informed that converging instrument approaches are in use.
- Each pilot is informed of the runway number on initial contact.
- ATS surveillance separation is maintained until one of the following occurs:
◦ One aircraft has landed.
◦ The airport controller is able to apply visual separation.
◦ Another form of separation is established.
LAHSO
Land and Hold Short Operations
What are differential winds?
When the wind speed and velocity at the surface is different than those that exist at higher altitudes
