Lester B. Pearson International Airport (CYYZ) recorded 146 detected events in the last 7 days. The breakdown: 66 unstable approaches, 66 returns to field, 9 go-arounds, and 3 rejected takeoffs. SkyMeter classifies these events from raw ADS-B trace data using deterministic detectors — go-around from altitude / vertical-speed reversals after final approach, unstable approach from gate-by-gate stability scoring against per-runway statistical envelopes, and stall / overspeed from broadcast IAS / Mach against per-type speed envelopes. Counts reflect detected events, not adjudicated incidents.

What these mean

Quick reference

↻
Go-around — aircraft on final approach aborts the landing and climbs out.
△
Unstable approach — speed/glidepath/configuration outside stable approach criteria.
✕
Rejected takeoff — takeoff abandoned on the runway, usually high-energy braking.
!
Stall — aircraft slowed below the angle-of-attack threshold; stick-shaker / stall-warn fired.
»
Overspeed — flap / gear / Mmo / Vmo limit exceeded; barber-pole alarm.
→
Runway overrun — aircraft passed the far runway end above taxi speed.
↗
Runway veer-off — aircraft exited the side of the runway during high-speed rollout.
═
Long rollout — used >90% of available runway length getting to taxi speed.
◆
Squawk 7500 — hijack code transmitted on the transponder. Usually a glitch; rarely real.
⌁
Squawk 7600 — lost-communications (NORDO) code. Aircraft can't talk to ATC.
✦
Squawk 7700 — general-emergency code. Pilot has declared.
↘
Diverted — landed at an airport other than the scheduled destination.
↺
Return to field — took off, climbed, landed back at the departure airport.

Detection is complicated — ADS-B is imperfect. Gaps, ghost signals, coverage dead zones, missing airport metadata, training patterns, parallel-runway activity, and unfamiliar aircraft types all create false positives. These are signals worth reviewing, not official incident reports.
