This category discusses the history of radar navigation and how radar technology has improved throughout the years. Basic radar principals are explained including the different types and how the components work. Scope interpretation is introduced in this category along with radar reflection. The many variables affecting radar return are discussed, such as varying terrain and weather. Inherent scope errors are explained along with the different radar enhancements that help the navigator. The many different uses for the radar are discussed and how each can help the navigator navigate through different terrain, weather, and altitude changes.

Rotating Flight Navigation Plotter – Rotating azimuth eases flight planning with direct course readout. 8 scales to meet the needs of all VFR aeronautical charts; nautical on one side, statute on the flip. Nautical-statute conversion scale also included.
Slide-Rule-Style E6B Flight Computer. On the circular side, black is used for the rate arrow and units to be calculated; Red is used for weight and volume; Blue is used for distance, time and temperature scales. On the wind side, colors are used to identify wind variation: blue identifies west (or right wind correction angle) and red identifies east (or left wind correction angle). ASA’s color E6-B is made with solid aluminum construction and features the functionality pilots have relied on for decades.
Additional Navigation Tools and Resources
- U. S. Air Almanac 2018 – The Air Almanac 2018 contains the astronomical data required for air celestial navigation, making it a necessary resource for all pilots and others attempting to chart routes based on celestial bodies. The Almanac also provides the Greenwich hour angle and declination of the Sun, Moon, and three navigational planets along with the Greenwich hour angle of Aries, all tabulated at 10-minute intervals.
- Davis Instruments Sextant – Used for measuring the angular distances between objects and especially for taking altitudes in navigation.
- Sight Reduction Tables For Air Navigation Pub. No. 249 – Vol 1. – These tables were designed for air navigation where weight and space are at a premium, however, they are very popular with sailors too due to the fact that Vol. 1 offers a speedier way to compute stars. Volumes two and three may also be helpful.
