Runway arrangement

1. A runway arrangement comprising:

a first runway section designated as a landing runway section;

a second runway section designated as a take-off runway section; and

a sterile safety area;

wherein the first and second runway sections are linked by the sterile safety area;

wherein the runway arrangement comprises a missed approach point for aircraft due to land on the first runway section, displaced from the start of the second runway section by a distance greater than H/tan θ 1 ;

wherein H is a safe turning height and θ 1 is an angle of ascent following a missed approach; and

wherein H is greater than 150 m and θ 1 is greater than 2°.

2. The runway arrangement according to claim 1 wherein the missed approach point is at least one of between 1,500 m and 4,500 m from the start of the second runway section, between 2,500 m and 3,500 m from the start of the second runway section, and approximately 3,000 m from the start of the second runway section.

3. The runway arrangement according to claim 2 wherein the missed approach point is a landing threshold marked on said first runway section.

4. The runway arrangement according to claim 3 wherein the landing threshold is at least one of between 100 m and 1,500 m from the start of the second runway section, between 100 m and 1,000 m from the start of the second runway section, between 300 m and 800 m from the start of the second runway section, and between 500 m and 800 m from the start of the second runway section.

5. The runway arrangement according to claim 1 wherein the second runway section is disposed at an angle to the first runway section.

6. A runway arrangement comprising:

a first runway section;

a second runway section;

a sterile safety area; and

a third, laterally offset, runway section;

wherein the first and second runway sections are linked by the sterile safety area and the second runway section is disposed at an angle to the first runway section; and

wherein the third runway section is arranged such that: the third runway section is substantially parallel to, and substantially longitudinally aligned with, said first runway section; the third runway section is laterally offset from said first runway section so that the centerline of the laterally offset runway does not intersect with the second runway section; and/or the runway arrangement satisfies the inequality D>L sin(θ) or D+O>L·sin(θ), wherein D is the separation between the first runway section and the third runway section, L is the length of the first runway section, θ is the angle between the first runway section and the second runway section, and O is the distance between the centerlines of the first runway section and the second runway section.

7. A runway arrangement comprising:

a first runway section;

a second runway section disposed at an angle to the first runway section;

a sterile safety area; and

a third runway section substantially in prolongation of the first runway section, thereby forming a ‘y-shaped’ runway arrangement;

wherein the first and second runway sections are linked by the sterile safety area; and

wherein the first and third runway sections are linked by the sterile safety area.
