Because some suit decided that it was going to be in our book <G>... Can't think of any other reason for it... Of course, we can also use the term maintain XXX when they are going up or down and we want them to stop... We like the word too, <G> we use it for speeds as in maintain 320 knots or greater, or on the other side of the coin, maintain 250 knots or less stand by for holding <G>...

Scott
