Stick to what you know. Mathematically, incorporating additional
information (even if it has some uncertainty) can inproves the error
estimate. While aircraft may make leeway and have wind that is not
usually incorportaed in theit DR. But you knew that right?

nav, are you saying that making more guesses *improves* the accuracy of prior
guesses?

mathematically, additional guesses degrades the accuracy of prior guesses.

what's more, aircraft also make leeway and also have current and actually have
air density differences (similar effect as the tide you mention re boats)


List Jackass and listen good. DR in flying is just compass and speed. In
marine navigation it is compass, speed, leeway, current and tide. By
allowing for these variables accuracy is much greater.
