We asked flight attendants to tell us about some of their most common terms. You may notice hinged flaps on the rear section of the wings. The flaps are extended downward during takeoff and landing, and then retracted at cruising altitude. Planes take off and land at slower speeds than they cruise, and that’s when these flaps help. During takeoff, the wing flaps extend downward, creating a larger wing area with a slight curve. This makes the air under the wing move slower than the air above the wing, which creates a lifting force. During landing, the wing flaps help reduce the aircraft’s speed by creating a drag force.

Bid Flight attendants put in requests (bids) for choice routes and specific monthly schedules. Reserve reserve flight atten- dants bid for days off only. When they don’t have a day off, they’re on call, which means they can be assigned a trip at any time (with at least two hours’ notice).

It’s a streak of condensed water vapor called a contrail — short for condensation trail. You know how you can see your breath when it’s cold outside? Well, that’s the same phenomenon that creates a contrail. As the hot exhaust from the jet engines mixes with the cooler air at higher altitudes, it condenses and forms a cloud of vapor. Contrails can also develop behind the wing tips, or even along the entire wing, due to the change in air pressure. Contrails form differently depending on altitude, temperature, and humidity. For example, a thin, short contrail usually indicates low humidity, whereas a thick, long contrail forms in humid air. august 2012 11
