Aircraft Technical and Systems

The Aircraft Technical and Systems tutorials cover all technical aspects of safely operating a light aircraft.

Here you can learn how an internal combustion engine works, discover the electrical system, understand airframe structure, hydraulics and landing gear, and all the cockpit instruments needed to safely fly.

This post will introduce the aircraft pitot static system which provides pressure readings to the three pressure-based primary flight instruments: the airspeed indicator, the altimeter,
This post is a part of our series on aircraft instrumentation and is dedicated to the airspeed indicator (ASI). This is an instrument that makes
An aircraft hydraulic system allows for forces to be applied, multiplied, and transmitted from one location to another through an incompressible fluid medium. Hydraulics are
The landing gear, or undercarriage, has two primary requirements: (1) to support the aircraft while on the ground and (2) to absorb the large loads
All modern aircraft are fitted with a braking system to assist in slowing and stopping when on the ground. Brakes are used not only to

The internal combustion (IC) engine is the powerplant used on almost all light general aviation aircraft today. Electrical aircraft motors promise a new and cleaner
Most internal combustion engines work on one of two principles of operation: a two-stroke cycle or a four-stroke cycle. Four-stroke engines are the predominant type
In the previous post on the topic of piston aircraft engines we discussed the four-stroke cycle, digging into the details of what happens inside the
In a light aircraft, the power and torque generated by the engine while it is running is not only used to produce the thrust necessary
In a previous post we introduced the various engine systems found on a light airplane. We now focus our attention to the ignition system, and
Internal combustion engines must be adequately lubricated and cooled while running in order to provide safe operation and to function as the manufacturer intended. In
An aircraft’s fuel system must be capable of providing a consistent delivery of fuel at the flow rate and pressure established by the manufacturer to
The carburetor forms a part of the engine’s induction system and is responsible for bringing together and mixing the air and fuel. This mixture is
An internal combustion engine is designed to convert the reciprocating motion of the pistons into rotational motion at the crankshaft. This rotational motion is then
