Thanks very much for that. . .. .What renders the IR invalid? Is it a time factor, apart form the so many approaches in so many months, etc, etc. Its pretty pathetic that I don't know this, but I've never got into the situation where it could be a factor before, so I've never really thought about it, I just know I don't want to have to go thru' the whole checkride etc ever again!. .. .Thanks again. . . . <small>[ 21 March 2002, 21:15: Message edited by: fernytickles ]</small>
