Instructions for completing the Navigation Log
Each column is headed by a name, a label (a single letter identifying that column) and a Source block. The Source block indicates where the information for that block must come from. Fill in each column from the sources indicated. Example: The HdgT column is also known as Column i, and must be filled in using information found in columns b and h. A brief explanation of each column is included below. The first table, marked Pre-flight Log, is used to determine inputs for the second block. Each leg is identified by departure and destination points, indicated in the first and last columns respectively. Start a new leg only where direction changes or a landing is made. The second block, labelled In-flight Log, is used during the actual flight. All columns except p, w and x must be completed before flight. Break the legs from the previous table into parts, using suitable intermediate checkpoints. Start with a short leg from the point of departure to a prominent landmark, from where the next leg can commence at a known airspeed and with a known heading. This technique ensures that manoeuvring in the circuit does not confuse the navigation. The Radio Information table contains callsigns and frequencies for each location during the flight. The Clearances block can be used to take down clearances and other information obtained during the flight.

Check in flight manual according to level Obtain from weather office for level chosen (direction and speed e.g. 270/15) Calculate from true track, wind and true airspeed, using graphic computer Add true heading and variation (subtract for Easterly) Calculate from true track, wind and true airspeed, using graphic computer Measure on map Divide distance by groundspeed, or use slide computer Point where leg ends Point where leg originates Actual time when point is departure is passed From previous table From previous table Adjust magnetic heading for compass deviation, using swing card in aircraft From previous table Measure on map Divide distance by groundspeed Actual takeoff time plus estimated cumulative leg time (calculate after departure) Revised estimate, using actual time at start of leg plus estimated leg time Point where leg terminates
