Hi
First of all thanks for all the great packages.
Can anybody tell me why at some airports,KLGA for example,as soon as an aircraft has started its take off roll the next one lines up. But at most airports the waiting aircraft holds short until the departing aircraft is well clear.
Thanks
Gary
Some hold short for ages other don't
Re: Some hold short for ages other don't
Gary if you are asking about real aviation, there are several reasons. In the last couple of years, the FAA here in the states mandated that in order for controllers to utilize "taxi into position and hold" operations as the previous aircraft is rolling down the departure runway, that there had to be at least two controllers working that runway. IOW if there is only a single controller responsible for that runway, then they cannot use those operations to speed up departures. So in an effort to speed up departures, they will use position and hold ops whenever they have the staffing levels to do so.
At LGA in real life, with the cross runway operations, they always try to squeeze as many departures as possible off of the departing runway BEFORE the next arrival aircraft gets too close to landing. With the cross runway setup there, you have to be in position and ready to go when they clear you or you will screw their whole system up.
I used to fly in there quite a bit when I was an airline pilot. Those controllers have zero patience and if you are slow to react or slow to taxi into position or start your takeoff role, you will be hearing about it over the radio for everyone else to hear. Everyone is always on edge there because there is a very fine line between normal operations and disaster. Many times we were instructed to taxi into position and "have them spooled". Meaning they wanted us to begin takeoff the moment we have received the clearance. Modern jets don't take that long to spool up to full power. The old school jets, 707's early 737s, anything with turbojets instead of turbofan engines take a bit longer to reach full thrust. So the controllers want to ensure that you will be rolling as soon as they say so.
It's pretty crazy because they are constantly having to time the departures to fit between the arrivals. There is no room for error since the departure and arrival paths cross.
Those were the days.....
