Aircraft Pressurization 601

Pressurization is the process of increasing air pressure inside an aircraft specifically the cabin. This is done due to reduce trapped gas, decompression sickness & hypoxia which is a condition of insufficient oxygen. An aircraft flies in high altitudes because it consumes less fuel due to low turbulence, it also […]


Airplane Actuators 240

Actuators are used to convert the hydraulic pressure into mechanical movement. ACTUATORS Single acting Double acting unbalanced Double acting balanced Hydraulic gadgets hydraulic motor – is a form of of rotary actuator. Hydraulic fuses are located near anti-skid module on top of the wheel well. They block lines in vulnerable […]


Aircraft fuel systems 982

An aircraft fuel system is designed to make fuel available to the engine at all times. The fuel tanks and reserve tanks are located at the wings of the aircraft and one in the belly of the aircraft inside next to the wings below the seats called center tank. vent […]


types of Jet Engines 751

In order for a plane to fly it needs thrust, this is attained by the heart of the aircraft that is the gas turbine jet engine. a small plane can be powered by a normal gasoline or diesel 4 stroke engine as described in my engine article but a large […]


how airplane lavatories works 805

in order to understand how airplane lavatories work we need to first understand how the basic home lavatories works. The principle of operation of a home toilet or lavatory is based on the science of gravity. When u flush a toilet u create a siphon that hence drains the bowl, […]


Pre-flight inspection & checks 472

Any aircraft is pre-flight inspected & checked before its on air to avoid mishaps and ensure its safe to commute on. each aeroplane has it own pre-flight checklist therefore we cant say for certain but basically most air craft pass almost through the following steps. Pilots follow a certain procedure […]


aircraft Electrical systems 831

An aircraft electrical system is made up of the normal electrical equipment which unlike a car has 14 or 28 direct current electricity. The equipment & systems include an auxiliary power units alternator or generator,variable frequency starter generator or alternator, battery, master/battery switch,alternator or generator switch, bus-bar, fuses, circuit breakers, […]


Parts of a helicopter & how it flies 464

A helicopter is an aircraft that derives both lift and propulsion from one or more sets of horizontally revolving overhead rotors rendering it capable of moving vertically and horizontally. below are its major parts and how they function.  Engine and transmission – The engine is of turbo-shaft jet engine type […]


Aeroplane environmental systems 729

Air supply and cooling, thermal control and pressurization of the cabin i.e HVAC (heating, ventilation & air conditioning) are considered to be part and parcel of the aeroplane environmental systems. Air in the aircraft is retrieved from the gas turbine jet engine at a point right before combustion. COOLING SYSTEMS […]


emergency equipment & systems in an aircraft 785

This are the equipment and systems employed in-case of emergency i.e like when a plane gets lost or crashes in order to track it, the passengers, flight crew, the pilot & co-pilot. They include :- flight data recorder (FDR) – keeps history of recent history of flight in a plane […]
