Optimising Movementsand Runway Capacity

Thought Process
• Identify Problem
• Determine what needs to be done
• Develop Solution
• Determine Success Parameters
• Implement Solution
• Assess Results
• Did it work or not
1-What are we trying to fix
Statement of Problem:
• Need to maintain runway capacity at all times
Why?
• Too much separation reduces landing rate
• Wastes available capacity
• Too close then breaks minimum separation
• Infringes safety requirements
• Increased number of Go Rounds
1-What do we need to happen
Need a Solution that helps users:
• Maintain mandated minimum separation
• Maintain planned arrival rates
• Reduces associated delays
• Remove Min Separation busts
• Reduce go rounds
1-Proposed solution
1-What outcomes do we want
We want maximized runway throughput that:
• Delivers the declared landing capacity
• Removes losses of minimum separation
• Delivers a safe, efficient service
• Reduces the number of Go Rounds
• Minimises delay

What are we trying to fix -2
Statement of Problem:
• Need to maximise runway capacity at all times
Why?
Weather:
• Causes loss of landing slots
• Introduces airborne delays/holding
• Causes flight cancellations
• Impacts passenger/airline customers

Winds 44%
What do we need to happen -2
Need a Solution that helps users:
In all Wind Conditions:
• Maintain planned arrival rates
• Maintain mandated minimum separation
• Reduce associated delays
Time Based Separation, is it feasible?

Time Based Separation Results
Pre and Post TBS >20 Knots Wind
TBS performance in Nov 2015
• Estimate over 25,000 minutes of delay saved versus distance based separation
15 days of strong headwinds
November 15, 2015 Storm Barney:
EUROCONTROL: Strong winds generated 65% of the total daily ATFM delay
LHR at the runway 21kts, gusting to 32kts, 80kts at 4000ft and 60kts straight down the runway at 3000ft35-40 Movements / Hour
