The winds are light.

English: The winds are light.

French: Les vents sont légers.

Your pilots will often announce wind conditions. Wind speed and direction are important to pilots as it affects their flying and landing. Stronger winds at ground level may also cause a more turbulent ascent or descent. Wind direction at runway level also usually determines which runway is used for take-off and for landing, as planes generally need to take off and land into the wind.

For the passengers though, few if any really care what the wind speeds are or which direction they’re coming from. They may only care if the winds are going to cause significant turbulence during take-off or landing, or if the winds are strong enough to cause delays.

Take Toronto Pearson International Airport (YYZ) as an example and the diagram of the airport's five runways below. As a flight attendant in Canada, you'll very likely fly in and out of YYZ very often. (It's an older diagram from Wikipedia as Terminal 2 no longer exists, but is still pictured.) You can see that the airport has three east-west runways but only two north-south runways. As planes usually take off and land into the wind, if the winds are strong enough and coming from the north or south, the airport uses its two north-south runways instead of its three east-west runways to process all of its departures and arrivals. During this time, the airport cannot handle its traffic at its regular capacity and air traffic control may need to delay flights. The weather may be fine otherwise, but this is an example of how something as simple as wind direction may cause delays.

When winds are light, they generally will not cause significant turbulence nor delays for take-off or landing, so when the pilots do mention that the winds are lig
