Primary Flight Display

🛩️A Primary Flight Display or PFD, found in an aircraft equipped with an Electronic Flight Instrument System is the pilot's primary reference for flight information.

🛩️The unit combines the information traditionally displayed on several electromechanical instruments onto a single electronic display reducing pilot workload and enhancing Situational Awareness.

🛩️The layout and information displayed on the PFD varies depending upon manufacturer and installation.

🛩️However, most Primary Flight Displays are configured with a central attitude indicator (AI) and flight director surrounded by other flight parameters.

🛩️Convention normally places the airspeed tape on the left side of the AI and the altitude and vertical speed references on the right.

🛩️Vertical deviation for ILS glideslope or VNAV (vertical navigation) is displayed to the right of the AI while lateral deviation from the ILS, VOR or FMS track is displayed below the AI.

🛩️A compass reference is provided at the bottom of the instrument while, in most cases, flight director, approach, autopilot and auto-throttle modes are annunciated across the top of the instrument.

🛩️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 ...
