The captain always sits in the left seat of the cockpit, a convention dating back to early propeller aircraft where left-seat positioning helped manage engine torque during takeoff.
着陸時に客室照明を落とす理由
Airlines dim cabin lights during nighttime takeoff and landing so passengers' eyes are pre-adjusted to darkness in case of an emergency evacuation.
高度で食べ物の味が変わる理由
At cruising altitude, passengers lose approximately 30% of their ability to taste sweet and salty flavors due to low humidity and cabin pressure.
気象指標としての飛行機雲
Short-lived contrails indicate dry upper air and fair weather, while persistent contrails that spread into cirrus clouds suggest approaching moisture and potential storms.
酸素マスクが供給する空気は12〜22分
The emergency oxygen masks in a passenger aircraft provide only 12 to 22 minutes of breathable air, which is enough time for pilots to descend to safe altitude.
ブラックボックスは実際にはオレンジ色
Flight recorders, commonly called black boxes, are actually painted bright orange to make them easier to locate in wreckage.

The upturned tips on modern aircraft wings, called winglets, reduce drag and save approximately 4-5% in fuel consumption.
航空機タイヤは極端な圧力に耐える
Aircraft tires are inflated to about 200 psi, roughly six times the pressure of a car tire, to withstand landing impacts at over 250 km/h.

飛行中に機体ドアは開けられない
It is physically impossible to open an aircraft door in flight because cabin pressure creates over 6 tonnes of force holding each door shut.
デッドヘッド：パイロットが乗客として移動
Airlines routinely fly pilots and crew as passengers, called deadheading, to position them at airports where they are needed for upcoming flights.
機内で最も汚れやすいのはテーブル
Studies have found that airplane tray tables harbor an average of 2,155 colony-forming units of bacteria per square inch, more than lavatory flush buttons.
