An annotated B737 naming the key features of an airframe.
An Etihad A380. Useful for showing and numbering a 4-engine configuration.
A Cirrus SR22. Our standard model for most light aircraft illustrations.
A Boeing 777 cockpit. Relatively detailed but the shapes of small items, such as knobs and switches, have been simplified to reduce the complexity.
Airbus A380 cockpit. Relatively detailed and VR ready. The shapes of small items, such as knobs and switches, have been simplified to reduce the complexity.
Generic conventional aluminium fuselage structure
A carbon composite fuselage barrel based on the Boeing 787. Created by winding fibre tow onto a mandrel. (Airbus uses a different system).

The Earth’s orbit during one solar year. With annotations. This animation shows the orbit of the Earth around the Sun along the Ecliptic over the course of one solar year.
The plane of the ecliptic and the Sun’s apparent path over the surface of the Earth
A 3D model of the Earth, featuring key points of interest and showing both magnetic dip poles and geomagentic poles.
Examples of infinite great circles for routes to the opposite sides of the Earth.
A small circle is any circle on the surface of the Earth whose centre is not at the centre of the Earth. The arc of a small circle between two points is greater than that of the great circle.
The shortest route between two points across the surface of the Earth is the arc of the great circle that passes between them. We show the arc of a great circle between points A and B , with the complete great circle continuing right around the Earth
This model show the change of great circle track compared to the constant rhumb line track.
This shows the cross-track difference between short and long tracks at different latitudes, N30° and N80°.
This shows the difference between the great circle track, following the surface of the Earth, the obvious route for any airborne vehicle compared with the theoretical shortest (underground) route.
This model shows a variety of great circles and rhumb lines on the surface of the Earth.
This shows that the rhumb line is always on the equatorial side of the great circle and is a track of constant bearing. The great circle is always on the polar side of the rhumb line. Except for the Equator and meridians of longitude, change bearing.
This shows that the intersection of 2 spheres produces a circular line of position.
Adding a third circle reduces the possible positions to just two points on the surface of a sphere.
Adding a 4th sphere eliminates 1 of the two points. 4 satellites are needed to fix your position.
A constellation of satellites is required to give global coverage 24/7.
