All pilots use this weather jargon
Q While watching a YouTube
presentation on general aviation, I encountered the use of the term “Information Juliet” and other “Information” names. What is the meaning of such terms, and are they used in commercial aviation?
— Steven Schwartz, Ohio A“Information“informs the that the pilot has received and understood the Automatic Terminal Information Service (ATIS) weather and information broadcast. The broadcast is given a letter designation and named by the phonetic alphabet. “Information Juliet” is weather and relevant airport information that was updated from the previous observation that would have been designated “Hotel.” All pilots (general aviation, airline and military) use this communication tool with controllers. Q What is the difference between a stabilator and an elevator? — Ahmedabad A The elevator is a movable panel
on the trailing edge of the horizontal stabilizer that causes the nose to pitch up and down. An elevator does not move the entire stabilizer, only the panel on the back.
A stabilator moves the entire horizontal stabilizer to pitch the nose up and down. It is more efficient than an elevator. Q I have read about a “flaperon”
being found as evidence in the MH 370 accident. What is this control surface’s function, and where is it found on the aircraft?
— Craig, Ivanhoe, Ill. A The flaperon on the B777 is located
just aft of the engine. It moves up and down, providing roll control like an aileron, and extends aft like a flap. The name is a combination of these two flight controls.
