✈️ New Aeronautical Information Circular (AIC) Detected
AIC: AIC 10/21
Published: 2025-12-26
Effective: 2020-02-27
Affected Location: Toronto/Lester B. Pearson Int’l (CYYZ)
🧠 What Changed (Summary)
A trial of a proposed amended Preferential Runway System (PRS) at Toronto/Lester B. Pearson (CYYZ) begins 27 Feb 2020 at 0000 local and replaces the existing PRS used nightly 0000–0629 local. The amended PRS changes how preferential runways are applied by using runway pairings (arrival/departure configurations) rather than separate ranked lists.
- Effective for trial: 27 Feb 2020 at 0000 local; on that date the amended PRS replaces the existing PRS.
- Applies during the nightly PRS period: 0000–0629 local.
- Rationale: Toronto Noise Mitigation Initiatives / 2018–2022 Noise Management Action Plan; updates a decades-old system given community growth and added runways.
- GTAA analysis retained existing first/second choices as best for noise mitigation: Arrivals—RWY 05 and RWY 15L; Departures—RWY 23 and RWY 33R.
- Existing third choice RWY 06L/24R is no longer a preferential runway; remains available as an alternate when RWY 05/23 is unavailable.
- Amended system: runway “pairings” (arrival/departure configurations) with one runway provisioned in each direction to help NAV CANADA adhere while selecting optimal runways based on weather/infrastructure.
- Details of the runway pairing table/figure are not included in the provided excerpt (Figure 1 referenced but not shown).
✈️ General Aviation Impact (Highlighted)
Airspace / Procedures:
- Expect night runway assignment at CYYZ to follow new preferential runway pairings during the trial (0000–0629 local).
- RWY 06L/24R will not be used as a preferential choice; may still be assigned as an alternate when RWY 05/23 is unavailable.
Operational Notes:
- Potential for changes to typical night arrival/departure runway expectations; plan for runway/configuration changes driven by PRS pairings plus weather and infrastructure availability.
- Trial feedback will be collected by GTAA; permanent change would require Transport Canada approval (per AIC).
VFR Impact:
- VFR pilots operating at/near CYYZ at night may see different runway-in-use patterns than under the prior PRS; monitor ATIS and anticipate noise-abatement-driven runway selections.
