Aircraft Emergency Systems: Oxygen, Fire, Evacuation
Aircraft emergency systems are the equipment and procedures that keep an aircraft survivable when something has already gone wrong — oxygen when the cabin fails, power when the…
Gas Turbine Engine: Parts, Types and How It Works
A gas turbine engine converts fuel into thrust or shaft power by continuously compressing air, burning fuel in it, and expanding the hot gas through a turbine. Almost…
Aircraft Fuel System: Components, Types & How It Works
The aircraft fuel system is the network of tanks, pumps, valves, lines and gauges that stores fuel and delivers it to the engine at the right pressure and…
Ram Air Turbine (RAT) Explained: How Aircraft Get Emergency Power When Everything Fails
A ram air turbine is a small propeller that drops into the airstream when an aircraft loses its normal power sources, using the aircraft’s own forward motion to…
Aircraft Lights Explained: Colours, Rules and Meaning
Look up at a night sky and you can read an aircraft’s direction before you can see its shape. That is the entire design intent behind aircraft lights:…
How Airplane Lift Really Works: What Textbooks Get Wrong
Ask how airplanes fly and you will almost certainly get the same answer: the top of the wing is curved, so the air travelling over it has further…
Inertial Navigation System: How an Aircraft IRS Works
An inertial navigation system knows where an aircraft is without receiving anything from outside it. No satellites, no ground stations, no radio at all. Tell it where it…
Aircraft Autopilot System: Components, Modes & Autoland
An aircraft autopilot system flies the aeroplane by continuously measuring how far it has drifted from what the crew asked for, and moving the control surfaces to cancel…
Nose Wheel Steering: Tiller, Shimmy Dampers and Towing
Nose wheel steering is what turns an aircraft on the ground below the speed at which the rudder becomes effective. On a light aircraft it can be a…
Aircraft Heat Exchanger: How It Works and Where It’s Used
An aircraft heat exchanger moves heat from one fluid to another without ever letting the two mix. That is the whole idea — and it is the reason…
