Accuracy of dead reckoning |
|
Federal Aviation Regulations, Part 63, Navigator Flight Test see flight test item 18. (no errors greater than 10%, average error no greater than 5%)
|

Weems pages 172 & 173 gives the accuracy
of dead reckoning as 5% of the distance traveled from
last fix.
Navigation and Nautical Astronomy, Dutton, 1934, (the official navigation training manual at the the U.S. Naval Academy) lists the factors affecting in flight dead reckoning.

H.
O. 216 (1967) recommends that navigators use a value of 20 nautical miles per hour plus 1 % of the
distance traveled since the last fix as an estimate of the accuracy of
dead reckoning. It states further that 50% of the time the
error should be only one-third of that amount.
