Flight Instruments

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

Airframe and Control Surfaces

Welcome to part one in a five-part series on airframe structures and control surfaces. The aim of this mini-series is to provide an introduction to
Welcome to part two in this five-part series on airframe structures. In this post we’ll be focusing on the fuselage; specifically, we discuss the design
This is part three in a five-part series on airframe structures and control surfaces. This tutorial focuses on the structural design of an aircraft wing
This is part four in of a five-part series on airframe structures. In the previous tutorial we discussed the wing structure, now we will focus
This is the final tutorial in a five-part mini-series on airframe structures and control surfaces. The previous tutorial focused on wing flap and slat systems.

Propulsion and Engine Systems

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

Aircraft Electrical System

The electrical system is essential to the proper functioning of any modern aircraft and is responsible for running everything from the lights and avionics, to
Welcome to part two in a three-part mini-series focusing on the aircraft electrical system. In the previous post we introduced the electrical system and discussed
This is the third and final post in a three-part mini-series on the aircraft electrical system. In the previous post we discussed the alternator which

Landing Gear Systems

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 wheels and tires (tyres) fitted to an aircraft are designed to support the full weight of that aircraft while on the ground, and transmit

Fundamentals of Aircraft Design

Welcome to the first of a ten part series on the fundamentals of aircraft design. The aim of this series is to give you an
In the previous post we introduced the four fundamental forces acting on an aircraft during flight: Lift, Drag, Thrust and Weight and examined how they
This is the third post in a series of fundamental aircraft design articles which aim to give you an introduction to aircraft design principles. In
The concept of wing sweep was introduced in the previous post which discussed the concepts of Wing Area and Aspect Ratio and their importance in
