Question 1803Navigation General70% to pass
Which statement about an estimated position is TRUE?
AI Explanation
The correct answer is A) It may be based on a single LOP or questionable data.
This is correct because an estimated position is a position that is based on less reliable information than a fix, which is a position determined by multiple lines of position (LOPs) from navigational aids. An estimated position may be based on a single LOP or data that is uncertain or questionable, making it less reliable than a fix.
The other options are incorrect because: B) An estimated position is generally less reliable than a fix based on radar bearings; C) The center of a triangle formed by 3 LOPs is not necessarily the estimated position; and D) Estimated positions are not necessarily based on soundings.
