Regretfully, FlightLiteracy (formerly FlightLearnings) will be turning out the lights after fifteen years. Google, in its infinite wisdom, has chosen to remove FlightLiteracy from its search results (the claim is that the content on this site is spam). We appealed their decision to shut us down, to no avail.

Unfortunately, since Google has a monopoly over internet search, this means that traffic levels on the site will drop to a level that makes maintaining it uneconomic. As time progresses, we will no longer be able to maintain the server space and will remove the site from the internet. Thanks to all who have supported us over the years.

To fight back against the monopolistic practices of companies like Google, we recommend using a competing search engine such as Brave (you get the added benefit of not being spied on by Big Tech) and advocating for anti-trust legislation from your representatives.

Navigation Systems

Go back to the main Flight Navigation Page.

Navigation systems are computer systems that determine position and calculate navigation information. Simple navigation systems rely on an initial position and basic instrument data, such as doppler groundspeed and drift, magnetic heading, and variation, to compute and constantly update the dead reckoning (DR) position. These systems require the operator to spend time to maintain system accuracy. Complex systems integrate information from a variety of sources using complex statistical algorithms to produce constantly updated, highly accurate position and navigation information. Some components of a navigation system may be stand-alone systems. This category examines navigation systems in general and the most common systems in detail—Inertial Navigation Systems (INS) and Global Positioning Systems (GPS).

Flight Literacy Recommends

Rod Machado's Private Pilot Handbook -Flight Literacy recommends Rod Machado's products because he takes what is normally dry and tedious and transforms it with his characteristic humor, helping to keep you engaged and to retain the information longer. (see all of Rod Machado's Products).

 

 

Recommended Tools

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.
