ACCURACY OF MANOEUVRING WITH A DECCA-NAVIGATOR UNDER DIFFICULT CIRCUMSTANCES

The navigation on a Decca homing-lane with a tanker of 250,000 tons was simulated: the Decca-navigator system being the only external navigational aid. The experimental variables were: forward velocity (6, 8 or 10 knots), presence or absence of skywave, and the resolution of the Decca-lattice (one lane was 825 m or 165 m wide). Six pilots carried out a specified manoeuvre three times in all conditions, the results show that it is difficult to follow one Decca-line, when the ship has started on an oscillatory track. The task becomes easier as speed increases. Skywave has an adverse influence on the performance, whereas decrease of the line-width has no facilitating influence at all. The marked individual differences suggest that training is often inadequate.
