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 […]

Spoilers, thrust reversers & Air brakes 1160

There are many ways to increase drag and reduce speed in an aircraft either when on the ground or on air, these includes spoilers, thrust reversers and air brakes. other methods of braking include wheel brakes, drogue parachutes and dive brakes. We will cover all these below :- spoilers – […]

Flaps found in an airplane 700

There are many types of airplane flaps but they all fall under two categories :- leading edge flaps Trailing edge flaps in the leading edge include Plain, slotted and Fowler flaps while in the trailing edge include Krueger flaps, slats, and slots. TYPES OF FLAP This combines both leading edge […]

plane wheels & tyres 740

Plane wheels and tyres are a very critical and sensitive part of a plane. in combination with the strut they combine together to form a planes oleo-pneumatic strut. plane wheels are classified in two:- loose/detachable flange type divided wheels Fusible plugs are placed in some wheels with tubeless tires to […]

Aeronautical structures & forces 640

stringer – this is a tie that surrounds the airplane. it takes tensile stresses or forces given by the fuselage structure by pressurization.The formers too resist this stresses. the two are shown below :- landing gear – has oleo pneumatic struts that resist compressive stresses when landing. Adhesive bonding processes […]
