Operations
Operations personnel are responsible for operating an airline's fleet of aircraft safely and efficiently.
Most wing structures have two spars, the front spar and the rear spar. The front spar is found near the leading edge while the rear spar is about two-thirds the distance to the trailing edge.
STRUCTURES
The fuselage frame of the Super Cub is constructed of steel tubes welded together to form a rigid structure. A number of highly stressed members are of chromemolybdenum steel (4130). Other members are of 1025 Steel.
Structure of the Atmosphere
The atmosphere is divided vertically into four layers based on temperature: the troposphere, stratosphere, mesosphere, and thermosphere.
Structure: The basis framework or skeleton of aircraft. or other engineering construction.
A structure in which the loads are carried partly by the frame and stringers and partly by the skin.
shp
Shaft horsepower. Horsepower measured at an engine output shaft.
The structures of the aircraft we are concerned with are required to withstand in-flight load factors not less than +4.4g to -1.8g at MTOW without any malformation - temporary or otherwise.
Aircraft structures are basically unidirectional. This means that one dimension, the length, is much larger than the others - width or height.
Two cone structure configuration.
Binding
What occurs when the friction at a joint is stronger than the linkage.
PYLON - Structure attached to wing or airframe to carry load, e.g. engines or weapons.

POSITION REPORT- A report over a known location as transmitted by an aircraft to ATC.
Note that this structure has a centerline, and casts a shadow.
Keep going straight ahead when the causeway ends, and fly to the far shore and a bit out over the Gulf of Mexico, until you see no shoreline if you take a view directly down.
facility - A structure or building that houses an operation.
FAF (Final Approach Fix) - The geographical position determined by visual reference to the surface, by reference to one or more radio NAVAIDS, by celestial plotting, ...
Airframe - the structure of an aircraft without the powerplant. It is generally considered to consist of five principle units - the fuselage, wings, stabilizers, flight control surfaces, and landing gear.
...
HANGAR An enclosed structure for housing aircraft. Originated with lake-based floating homes of the original German Zeppelins in which they were 'hung' from cables.
HEAVY JETS See 'Large-Cabin Jets.' ...
Air Traffic Control Center - A drafty, ill-kept, barn-like structure in which people congregate for dubious reasons. Alternate Airport - The airport that no aircraft has sufficient fuel to proceed to if necessary.
Paper core is becoming increasingly common in boat interior joinery, but is not recommended for hull and deck structures. If paper core gets wet, it goes all mushy, just like cardboard left out in the rain.
An Emergency Location Transmitter is a radio transmitter attached to the aircraft structure used as an alerting and locating aid for survival purposes. It operates from its own power source on 121.5 Mhz and 243.
The Chrome-Moly SAE 4130 steel tube fuselage was retained in the cabin area while the entire empannage was redesigned as an aluminum monocoque structure.
Training at an FAA certificated pilot school is structured. Because of this structured environment, the CFRs allow graduates of these pilot schools to meet the certification experience requirements of 14 CFR part 61 with less flight time.
Flying in the mountains with its large structures makes it very difficult to judge distance and scale. reason is that you look small compared to the mountains.
Because of its metallurgy, it's nearly impossible to design an aluminum structure that, if used enough, won't eventually develop fatigue cracks.
A well-designed sheet-metal aircraft also provides superior crashworthiness, as an impact's energy is absorbed by progressively collapsing (deforming) the metal structure, as opposed to splintering or shattering upon impact.
Other key priorities include maintaining the current airport infrastructure; increasing the capacity of facilities to accommodate growing passenger and cargo traffic volumes; ...
Keeping in mind that the tailcone is a monocoque structure (there is no frame inside it) the structural rigidity depends on no dents. Think of a beer or soda can: they're pretty strong until they are dented at which point they can be easily crushed.
For those who prefer more structure to the information available at the BGA, we have organized an alternative to the unstructured approach--a number of guided tours through the site.
SOUND INSULATION - (1) The use of structures and materials designed to reduce the transmission of sound from one room or area to another, or from the exterior to the interior of a building.
(1) An activity directly undertaken by any public agency, including but not limited to public works construction and related activities, clearing or grading of land, improvements to existing public structures, ...
A small radio transmitter fixed to an aircraft's structure which is automatically activated by impact or water immersion and transmits a code on emergency frequencies enabling SAR satellites or search units equipped with DF to locate the crash or ...
Speed Brakes Large panels that fold out of the aircraft structure to provide a lot of extra drag to the air. They are not part of the wing structure, but are usually mounted on the fuselage.
In Der Vogelflug als Grundlage der Fliegekunst (Bird Flight as the Basis of Aviation), he examined in detail the types and structure of bird wings, the method and aerodynamics of bird flight, ...
FAIRING - An added streamlining structure or auxiliary member, most often of light metal, whose only purpose is to reduce drag.
The main criterion here is the 90% test, under which the aggregate lease rentals during the lease term must not exceed 90% of the lessor's total cost (including interest and fees) for acquiring the asset - ie, full payout structures must be avoided.
They routinely assume there will be small structures and trees rising 200 feet above the land surface, but the trees on Blue Hill are probably closer to 100 feet. This is helpful, but we shouldn't rely on it.
On later helicopters where the manufacturer has attempted to raise the speed of the helicopter, the landing gear is retractable to reduce the amount of parasite drag produced. Generally, for a given structure, ...
The part of an aircraft's structure which connects an engine to either a wing or the fuselage.
Passenger Name Record (PNR)
The official name of one's reservation in a computer reservation system (CRS) ...
An aircraft’s main body structure housing the flight crew, passengers and/or cargo cabin to which the wings, tail section and engines are attached.
General Abbreviations

There are some rules involved about how close a pilot can come to clouds, restricted or controlled airspace, and ground structures, and those rules are referred to as visual flight rules. Most small plane flying is conducted under VFR.
In the 1860's Mozhaiski began designing a flying machine. He based his design on the structure of birds' wings. He also studied air kites. During this period Mozhaiski received financial aid from the Military Ministry for his research.
Your ELT should be mounted on a substantial structure, facing forward. It will help rescuers to locate you should you crash.

Initially, the wing structure consisted of two steel spars, and was also fabric-covered.
1. Starting climb for air-to-surface attack. 2. Max performance climb out of low altitude structure.
POPEYE
Flying in clouds or area of reduced visibility.
The above points should be clear, as in airplane work you are dealing with a structure which is safe with perfect materials and workmanship. The factor of safety, however, is not great enough to permit carelessness, or defective material. Linen.
Of course the whole thing falls down if you consider that if the radio or radar failed now, the American is going to merrily trot outside controlled airspace if it continues on that heading for long enough, and depending on the airway structure ...
