The correct spelling of the term "landing gear" can be explained using IPA phonetic transcription. The first syllable is pronounced /ˈlændɪŋ/, with stress on the first syllable and the second syllable pronounced with a short "i" sound. The second word, "gear," is pronounced /ɡɪr/, also with stress on the first syllable and a short "i" sound. Thus, the correct spelling of this term is "landing gear" and not "landing gair" or "landing geer," which are common misspellings.
Landing gear refers to the set of structures and mechanisms that support an aircraft during takeoff, landing, and ground operations. It is an integral part of an aircraft's structure and plays a crucial role in providing stability and facilitating safe landings.
Typically located at the lowermost part of the aircraft's fuselage, the landing gear consists of several components that work together to absorb the forces generated during touchdown and taxiing. These components include wheels, tires, shock absorbers, struts, brakes, and assemblies that allow for retraction and extension of the gear.
During takeoff, the landing gear remains extended to provide stability and prevent the aircraft from rolling excessively. Once the plane reaches a safe altitude, the landing gear can be retracted into the fuselage to reduce drag and increase aerodynamic efficiency.
For landing, the landing gear is again extended to provide a solid base for touchdown, ensuring that the aircraft remains upright and stable on the runway. The shock absorbers and struts help absorb the impact forces during landing, reducing stress on the aircraft's structure and its occupants.
The landing gear also allows the aircraft to safely taxi on the ground, providing support and mobility during ground operations. It allows for steering and facilitates directional control during taxiing.
Overall, the landing gear is a crucial component of an aircraft that contributes significantly to the safety and maneuverability of both commercial and military aircraft.
The word "landing gear" is composed of two individual words: "landing" and "gear".
The word "landing" originated from the Old English word "landung", which came from the Proto-Germanic word "landōną". This word referred to the action of coming to rest on land or reaching the shore. Over time, "landing" evolved to encompass various meanings related to the act of a plane touching down or alighting on the ground.
The word "gear", on the other hand, was derived from the Old Norse word "gervi", which meant "equipment" or "apparel". This term gradually transformed into "gear" in English, referring to multiple mechanical components or equipment used for a specific purpose.
When combined, the term "landing gear" came to represent the mechanical components and apparatus designed to support an aircraft during landing and takeoff.
