Alert Airport at a glance
Alert Airport is a medium airport in Alert, Nunavut, Canada, known to airline systems as YLT. The field elevation of 100 ft (30 m) is the number every arriving pilot dials against QNH — circuit heights and initial approach altitudes at CYLT are all figured from it. There is no scheduled airline service listed here — typical traffic is general aviation, training and local operations.
The single runway, 05T/23T, offers 5,500 ft (1676 m) of gvl surface, with runway lighting for night operations. Runway numbers give magnetic orientation: runway 05T points roughly 50° magnetic.
For the weather side of planning, the live METAR and TAF page for CYLT shows the current observation decoded line by line — wind on an instrument dial, visibility, cloud layers and the resulting flight rules — refreshed continuously from official sources.

Flight-planning notes for Alert Airport
Density altitude is the quiet performance-killer at any field: on a hot day the 100 ft field elevation of Alert Airport can translate into a substantially higher density altitude, stretching take-off rolls and flattening climb rates — run the numbers rather than trusting the feel of a standard day. Expect published instrument procedures, controlled airspace and clearance requirements; slots and handling may apply to general aviation traffic.

Where this data comes from
The reference layer behind this page builds on the OurAirports dataset — a public-domain, community-maintained register of the world's airports that many flight planners and apps rely on — with equity records preserved from documented historical listings where the dataset is silent. Figures are carried as published: elevations as surveyed, coordinates as filed, runway dimensions as recorded. Nothing is estimated to fill a gap, and the whole layer regenerates from source on every site build, so corrections upstream arrive here automatically.
