? embark Did You Know? What’s the difference between a captain and a first officer? Every US Airways flight requires at least two pilots to operate the aircraft. The captain, who sits on the left side of the cockpit, is the commander of the plane and is legally responsible for the aircraft, passengers, and crew and for making major command decisions. The first officer, who sits on the right side of the cockpit, shares flying duties and tasks with the captain, is responsible for any task delegated by the captain, and weighs in on major decisions. The designation between how does a plane turn? a captain and a first officer is based on seniority with the airline. Captains are distinguished with four bars on their epaulets and jacket cuffs, while first officers have three bars. No matter the rank, every pilot is required to have the same level of initial qualification training and yearly continuing qualification training. illustrations by nigel holmes to put it simply, planes turn by banking to the left or the right. the key to this banking motion is found on the wings. on the back edge of each wing, near the wingtips, is a movable surface called an aileron. to turn left, for example, the pilot moves the plane’s controls to the left, which makes the left aileron deflect up and the right aileron deflect down. this changes the effective shape of each wing, and therefore the amount of lift that each produces: the left wing produces less lift, which causes it to News, Notes, and Inflight Insights Why do my ears pop? ★ It’s all about air pressure. As a plane climbs and descends, the change in altitude causes a change in air pressure — the higher the plane, the lower the pressure. The cabin is pressurized to protect you from any significant shifts in pressure, but your ears can be sensitive to even the slightest changes. As a plane takes off, the air pressure decreases and causes the air trapped in your inner ear to push your eardrums outward. This expansion may result in discomfort and muffled hearing. However, your body naturally equalizes the pressure in your ear, which can cause the popping sound. As a plane descends, the opposite occurs. Air pressure increases while the inner ear is still adjusted to the lower pressure and therefore the extra pressure pushes the eardrum in. To help equalize the pressure in your eardrums, you can try holding your nose and mouth closed and blowing gently, or try swallowing or yawning. dip down, and the right wing produces more lift, which causes it to tip up. the net result? a bank to the left. a smooth and efficient turn requires a few additional control inputs from the pilot. to keep the plane’s nose pointed in the right direction throughout the bank, the pilot adjusts the rudder using foot pedals. and to maintain altitude throughout the turn, the pilot typically adjusts the elevator to keep the aircraft level. march 2013 11
