Hello forum peeps:
Recently, I and a few other pilots had this discussion about Same Runway Separation and it’s meaning. So in this post, I will talk about it a little bit here.
What is SRS and how does it work?
SRS or same runway separation is the act of separating a departing aircraft from a preceding departing or arriving aircraft using the same runway by ensuring that it does not begin takeoff roll until:
The other aircraft has departed and crossed the runway end or turned to avert any conflict. If you can determine distances by reference to suitable landmarks, the other aircraft needs only be airborne if the following minimum distance exists between aircraft or preceding landing aircraft is clear of the runway.
This can be used when:
1) Category 1 (3,000 feet of runway) aircraft are used;
2)When a Category I aircraft is preceded by a Category II aircraft-(3,000 feet of runway);
3)When either the succeeding or both are Category II aircraft(4,500 feet of runway);
4)When either is a Category III aircraft-(6,000 feet of runway)
5) When the succeeding aircraft is a helicopter, visual separation may be applied in lieu of using distance minima.
Aircraft category definitions:
CATEGORY I- small aircraft weighing 12,500 lbs. or less, with a single propeller driven engine, and all helicopters.
CATEGORY II- small aircraft weighing 12,500 lbs. or less, with propeller driven twin-engines.
CATEGORY III- all other aircraft.
Wake turbulence procedures remain in effect during this.
Well, I hope you learn something new today and hope this can be implemented into controlling the busier airports. Airports like Chicago-Midway, LaGuardia and Atlanta-Hartsfield Jackson use these procedures.
