[Ref ISBN 978-1-61854-262-5 Chapter 18, FAA-H-8083-25B] Q: What’s the best way to avoid accident and prevent error? A: To avoid accident and prevent error, pilots should learn and apply ADM, CRM and Threat and Error management skills in their daily operations. Actually, the goal of all flight crews is good ADM and the use of CRM […]
What do you dislike about aviation? (Blood Donation)
[Ref ISBN 978-1-61854-262-5 Chapter 18, FAA-H-8083-25B Chap 17] Q: What do you dislike about aviation? (Blood Donation) A: I might not making a blood donation as normal person. Blood donations can cause hypemic hypoxia due to the fact that not enough blood is available to carry a sufficient amount of oxygen to the cells. […]
[Ref. Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 7-20, 7-21, 7-22] (Last Update 2020 Apr 24 1400Z) What’s Turbine Engine? The turbine engine is a kind of powerplant pulls air into the engine. The air is compressed before mixing with fuel and burnt to produce thrust by increasing the velocity of the air flowing through the […]
[Ref. Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 7-27, 7-28] Accidents attributed to powerplant (engine) failure from fuel contamination have often been traced to : Inadequate preflight inspection by the pilot Servicing aircraft with improperly filtered fuel from small tanks or drums Storing aircraft with partially filled fuel tanks Lack of proper maintenance Water is […]
Stall strips : Stalling at the wing root first
[Ref The Pilot’s Manual PM2 Ground School Page 46, FAA-H-8083-25B Page 5-25, Wiki, Boldmethod] Stall strips is a fixed device employed on the leading edge of fixed-wing aircraft to introduce a stall prematurely Stall strips are used to initiate flow separation at chosen locations on the wing during high-angle of attack flight, they act as a warning […]
Whether long wing span is better or not?
Before we go into the conclusion, we should understand that sometimes longer wing span is not necessarily make impact, but in particular aspect ratio, it does has certain effects. Aspect ratio ∝ Adverse yaw effect Aspect ratio ∝ weight of the wing structure However… Aspect ratio ∝ 1/ Wingtip vortices
pressure-type carburetors ≠ fuel injection system
[Ref. Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 7-8] This article aims to point out that pressure-type carburetors is different from fuel injection system. pressure-type carburetors ≠ fuel injection system There are two common types of carburetor System – 1) Float type and 2) Pressure type Pressure-type carburetors discharges fuel into the airstream at a […]
What’s “Critical AoA” / “Stalling AoA”
[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. Wiki, Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 4-4] The air density, density of air or atmospheric density, denoted ρ (Greek: rho), is the mass per unit volume of Earth’s atmosphere. 3H , low(er) air density – Hot High Altitude Humid Air density changes with variation in actual height (altitude), temperature and humidity. At 1013.25 hPa […]
[Ref Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 12-23] Tornadoes is literally the most violent sort of thunderstorm ! Studies show that wind in such a vortex can exceed 200 knots with pressure inside the vortex quite low. The three (3) common type of tornadoes are: “funnel cloud” – if the cloud does not reach the […]
