I am interested in B737s & larger aircraft.
ATC staff & pilots work lower than a lot of pressure.
Extending separation by 10% would trim down pressure on both pilots & ATC staff?
There are compromises in most things but this one creates extra stress & risk due to landing individual a dangerous slice of the flight?

NATCA: Safe Aircraft Separation Target Missed
The number of serious incidents of aircraft getting too close in the atmosphere rose sharply in October, exceeding FAA’s objective for the month by 36 percent, according to the National Air Traffic Controllers Association (NATCA). The bargaining part representing controllers said there be 38 serious incidents classified as Category “A” and “B” in October, surpassing FAA’s “performance limit” of 28. An functioning error is defined as a violation of separation standards that outline minimum safe distances between aircraft. NATCA said the missed target is not surprising due to a shortage of veteran controllers
Answers: The seperations at respectively airport would necessarily be different depending on 1) all along the runway(s); 2) the number of "turn-offs" there are (which allow the aircraft to exit the influential runway after its landing roll-out); 3) Whether there be multiple runways in use; 4) etc. ALSO: the seperation also have to allow for the landing speed, and roll-out time for each type of aircraft, which would be at variance depending upon the aircraft type (more seperation for 747's - less for DC-3's). It is the approach controller(s) who own the final say base on their knowledge, experience and how they control the landing flow.
Some airports parkland one as another is taking off. Others use Land and Hold Short Operations (LAHSO) that requires the landing plane to hold short of the crossing runway during the landing roll out while another plane on the crossing runway take off.
The issue is the number of departures/arrivals conbined next to other traffic going to nearby airports controlled by like peas in a pod ATC controllers.
People in the USA are extremely self-seeking when it somes to being independent. There are so heaps RJ's jamming up the system that all require impossible to tell apart separation that the larger ones have. The use so many flights is that empire don't want to wait for a 1045 flight, they want to bestow at 1000. So airlines add frequecy beside smaller planes even though the flights are not full rather than hang on to larger airplanes on the routes but with smaller number frequency.
I just fly 'em. I'm not a bean counter, but the number of RJ's surrounded by some big airports like LGA, ORD, and DCA is staggering and it really cause delays, especially when the weather go bad.
I'm gonna disagree near the idea of a 10% increase of separation, for one point, the total number of arrivals and departures from the busiest airports would drop dramatically, leading to longer delay and fewer flight slots.
Also I gotta disagree near the other guy and say that the airlines are cause the bulk of the problem, not GA aircraft. They set the schedules, so if they really have a problem with delay they could simply merge a few flights and get bring in people dawdle another 30 mins for a flight instead of having more planes sitting on tar all knowing they'll be delayed that long anyway.
Hi, I used to work at a colossal airport in England and planes land every three minutes in the busy time of year - this would be minimum time between landings.
