Question

you are operating an suas that does not have gps or an installed ground speed limiter. how can you determine the speed you are operating?
answer choices
dead reckoning.
pilotage.
wind triangle.

Explanation:

Dead - reckoning is a method of calculating one's current position by using a previously determined position, or fix, and advancing that position based upon known or estimated speeds over elapsed time and course. Without GPS or a ground - speed limiter, dead - reckoning can be used to estimate speed and position. Pilotage is more about navigation using visual landmarks and the wind triangle is used for wind correction in flight planning and not the primary way to determine speed without GPS or speed limiter.

Answer:

A. Dead reckoning
