Not quite the greatest thing since sliced bread though.I can see what the selected level is thanks to "mode s",but if it's low pressure and crews don't select 1013mb when cleared to a flight level,it can lead ATCO's into a false sense of security that the a/c will level at the instructed Flight Level.Been there,done that!No substitute for monitoring rate of climb against traffic 1000' above cleared level.(assuming we have time to do so!)
