Grobit - tha's the way it works at Luton. TWR will ofter request an early right/left turn if they have slotted a departure in while a biggy lumbers its way to the turning circle. Equally, they will often request the littlies to keep speed up if they are trying to slot in a landing. They equally are not afraid to ask for the littly to break off and take up a hold (It has happened to me a around 500ft) - but that is just the way it should be
You guys have a job to do, we are just having fun!
