[Ref Aviation Maintenance Technician Handbook–Airframe, Volume 2, FAA-H-8083-31A 13-5] “Bogie” is describing the attaching mechanism which has more than two wheels are attached to single landing gear strut.
[Ref Youtube] The more powerful the engine, the bigger the fin and rudder are needed to counteract the aerodynamic force during engine failure situation. However, the bigger and higher fin may be oversize and cannot be fitted into a hanger. Therefore, manufacture can use the dorsal fin. Dorsal fin doesn’t intersect straight into the airframe, […]
[Ref IATA DG Class 10 Learning Kit] In real operations, NOTOC has two part: the upper part is the DGs and the lower part is special loads, such as live animals (AVI) and human remains (HUM). The NOTOC must contain, at a minimum, the following information: The airport where the goods will be unloaded (destination […]
[Ref IATA DG Class 10 Learning Kit] Dangerous goods are articles or substances which are capable of posing a hazard to health, safety, property or the environment. Read More – Who establishes the criteria and What’s the Legal Basis? The United Nations (UN) Subcommittee of Experts on the Transport of Dangerous Goods establishes the criteria […]
[Ref Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 5-3] What’s Critical AoA? Critical AOA = stalling AOA ≅ CLmax point ; Critical AoA is the AoA angle in which the wings have reached CLmax point. After reaching Critical AoA, any further increase AoA will result in the wing stalling.

[Ref. Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 7-9, 7-19] Roughness normally is due to spark plug fouling; Both over-rich or over-lean mixture can cause engine roughness Over-rich mixture induced roughness?! Why it happens? (over-rich mixture → excessive carbon buildup → spark plug fouling → roughness) Roughness is normally caused by over-rich mixture, which […]
[Ref FAA-H-8083-25B Page 5-49, 6-10, Skybrary] What’s Spoiler? Spoilers, is a kind of secondary or auxiliary flight controls as well as high drag devices often found in high speed aircraft, are used on the upper surface of the wing to spoil or reduce lift. Speedbrakes? When spoilers are used as speedbrakes, they are selected by the […]
