Pilotage and Dead Reckoning
Pilotage and dead reckoning are fundamental navigation methods that use outside visual references together with heading, time, distance, groundspeed, and wind information to maintain position awareness.
Pilotage
Pilotage determines aircraft position by comparing identifiable features on the ground with an appropriate chart or navigation reference.
Useful checkpoints should be distinctive, visible, and suitable for confirming progress along the intended route.
Dead reckoning
Dead reckoning estimates position from a known point using direction, time, speed, distance, and wind correction.
The estimate should be updated as actual groundspeed, wind, or route progress becomes clearer during the flight.
Wind correction
Wind can move the airplane away from the intended ground track even when the heading remains constant.
The pilot applies an appropriate wind-correction angle and then evaluates actual track using checkpoints or other available navigation information.
Time and groundspeed
Comparing planned and actual time between checkpoints helps the pilot estimate groundspeed and revise later estimates.
A meaningful difference between expected and actual progress can indicate wind variation, navigation error, or another planning assumption that needs correction.
Position awareness
Pilotage and dead reckoning work best as continuous processes rather than occasional checks.
The pilot should maintain awareness of the last confirmed position, the next expected checkpoint, nearby airspace, terrain, airports, and suitable alternatives.
When a checkpoint is missed
If an expected checkpoint does not appear, continuing without resolving the discrepancy can compound the navigation error.
The pilot should use available information and appropriate procedures to re-establish position rather than assuming the original estimate remains correct.
Common navigation errors
- selecting weak or ambiguous checkpoints;
- failing to correct for wind;
- not updating groundspeed or time estimates;
- losing track of the last confirmed position;
- fixating on navigation while neglecting aircraft control or traffic;
- continuing after position uncertainty develops without resolving it.
Why pilots practice pilotage and dead reckoning
These methods build an understanding of how heading, wind, time, distance, and ground references relate to actual aircraft movement.
They also provide useful navigation skills when electronic information is unavailable, degraded, or needs to be cross-checked.
Useful practice considerations
Depending on the aircraft, conditions, training objective, applicable standards, and instructor guidance, practice may include:
- selecting distinctive visual checkpoints;
- maintaining the planned ground track;
- applying and adjusting wind correction;
- recording or comparing checkpoint times;
- estimating actual groundspeed;
- updating later time and position estimates;
- maintaining awareness of terrain, airspace, and alternatives;
- re-establishing position when an expected checkpoint is missed.
