Runway Designation

🛩️Since aircraft are affected by the wind during takeoffs and landings, runways are laid out according to the local prevailing winds.

🛩️Runways are numbered (designated) to the nearest 10° in relation to magnetic north based on approach direction.

✈️Example: 084° is marked 08
✈️Example: 085° is marked 08 or 09
✈️Example: 086° is marked 09

🛩️This number becomes the runway's name, and is how it is referenced by Air Traffic Control (ATC)and other pilots.

🛩️The opposite end of the runway is then marked with the reciprocal heading.

🛩️Reciprocal heading is determined by adding or subtracting 180° from the runway heading.

🛩️You must therefore add 180 to any runway 180 or below, and subtract 180 to anything 180 or above.

✈️Example: (using runway 26) 260° - 180° = 080°
✈️Example: (using runway 08) 080° + 180° = 260°

🛩️If your answer comes out to be greater than 360, or negative, then you added when you should have subtracted or vice versa.

🛩️Parallel runways are designated with numbers but also as "L," "C," and/or "R" which stand for left, center, and/or right.

✈️Example: 02L, 02C, and/or 02R

🛩️When there are only 2 parallel runways, the "center" is omitted and only "left" and "right" is used.

🛩️Note wind directions are reported in degrees magnetic, to provide an applicable reference to the runway direction.

🛩️A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, combustion chamber is fed high pressure air by the compression system. 🛩️The combustor then heats this air at constant pressure. After heating, air passes from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the air is directly fed to the nozzle. 𝐀𝐧𝐧𝐮𝐥𝐚𝐫 𝐓𝐲𝐩𝐞 ✈️The most commonly used type of combustor is the fully annular combustor. Annular combustors do away with the separate combustion zones and simply have a continuous liner and casing in a ring. There are many advantages to annular combustors, including more uniform combustion, shorter size, lighter, and less surface area. Annular combustors tend to have very uniform exit temperatures. They also have the lowest pressure drop of the three...

🛫A monocoque structure uses its outer shell to support stresses and loads applied to it, whereas a semi-monocoque structure has an internal "skeleton" of supports and braces to keep its shape rigid and strong. 🛫The vast majority of pressurized aircraft are semimonocoque to help distribute stresses equally along the fuselage during flight. 🛫However, some helicopters use monocoque structure to maximize internal space in the flight compartment. 🛫Monocoque fuselage has its skin holding the skeleton structure together while the semi-monocoque has both the skin and the skeleton holding together. 🛫Semi-monocoque also has "stringers" running horizontally down the plane to help hold the frame together. 🛫The monocoque fuselage also cannot be used for airframes after a certain size (small aircraft with single engine), but the semi-monocoque has been used from single piston engines to commercial airliners. 🛫A monocoque design would also have ...

Empennage 🛩️The empennage of an aircraft is also known as the tail section. Most empennage designs consist of a tail cone, fixed aerodynamic surfaces or stabilizers, and movable aerodynamic surfaces. 🛩️The tail cone serves to close and streamline the aft end of most fuselages. The cone is made up of structural members like those of the fuselage; however, cones are usually of lighter construction since they receive less stress than the fuselage. 🛩️The other components of the typical empennage are of heavier construction than the tail cone. These members include fixed surfaces that help stabilize the aircraft and movable surfaces that help to direct an aircraft during flight. The fixed surfaces are the horizontal stabilizer and vertical stabilizer. The movable surfaces are usually a rudder located at the aft edge of the vertical stabilizer and an elevator located at the aft edge the horizontal stabilizer. 🛩️The structure of the stabilizers is very similar to that which ...
