In a pungent note published in the October 1966 Journal (Bad Language, Journal, 19, 523), Wing Commander E. W. Anderson drew attention to some of the confusion that had arisen through lack of a precise and accepted navigational terminology. He suggested that if a number of the more contentious terms were defined and accepted by the Institutes of Navigation, the use of ‘bad language’ might die out. It has now been agreed that the British Standards Institution should compile a navigational glossary and to set things going the Institute has formed, under Wing Commander Anderson, a sub-committee to try to sort out some of the terms over which ambiguity has arisen.
