Inline Runways

BACKGROUND

The Nature of the Problem

• Underlying growth

• Congested facilities

• Environmental Pressures

‘Surface density’ is a measure of the efficiency of the use of space

It varies considerably

Developing a Solution

• What exactly is the issue?

• How could it be achieved?

• What is the role of technology?

THE INLINE RUNWAY CONCEPT

How it works

A single runway

With an in-line runway

Safety zone - kept clear of aircraft

Runways are independent –Gives the throughput of two runways

Departures Arrivals

At off-peak times, using the further runway can reduce noise

Use this runway in mixed mode at quiet or off-peak times Noise reduction here due to

displacement of approach path

Land on further runway

Aircraft do not enter the safety zone

Key:Not to scaleILS localiser antenna Near/far field monitor

Safety zone Width = 650m

Air Traffic Control procedures are designed for the inline runways

Missed approach procedures

Considerations:• ICAO/EASA/FAA rules• Obstacle surfaces• OEI operations

Simulations were used to design ground procedures

KEY FEATURES AND ADVANTAGES

Key Features & Advantages

• Uses existing infrastructure

• Uses existing flight paths

• Limits land-take and impact

• Limits runway crossings

• May have some landside advantages

• No restriction on landside development in 'single' runway configuration.

• Can develop either side if landside access is feasible.

• Remote sites retain good views

Landside Advantages

Where else might this be possible?

• Long, thin site

• Where the severance issue is limited

• Where peak hour runway capacity is limiting

What might have been?

The actual 2nd runway

If it had been inline

Where Else?• No runway

crossings (so more capacity)

• Would have removed a hazard on the existing runway

Where Else?• No runway

crossings (so more capacity)

• Would have removed a hazard on the existing runway

Vision

• A credible solution has been developed

• Builds on existing practice, but not constrained by it

• It could be a solution elsewhere
