Nautical Term: IUHATUTC
Definition of IUHATUTC
This nautical term, ‘If Used, Half Actual Time Used To Count,’ is employed when calculating time for certain navigational situations. For instance, if a ship’s navigation team needs to recalculate their position due to an error in their previous dead reckoning, they would apply the ‘If Used, Half Actual Time Used To Count’ principle. They would record the exact time they began the new dead reckoning calculation. Then, they would apply the ‘half actual time’ component to this calculation. This would mean they would subtract half the time it took them to perform the new dead reckoning calculation from their final result. The end result would then be their new estimated position. By using the ‘If Used, Half Actual Time Used To Count’ principle, the navigation team can more accurately estimate their position and make more informed navigational decisions.
