The Equation

Demand

G + A (capacity)

= v Hotspot = ATFCM (Flow rate)

V = variable

PART III: THE APPROACH

(example case study)


12

Current world – NMOC tools (CHMI Data)

>45 aircraft expected into the

stacks between 05:40-06:40which would have led to

increased airborne holding

shortly after


13

Airports Introduce new prediction tools linked to Network via AOP/ACDM & DCB

This equates to peak airborne

delay anticipated at 07:00

with a reduction shortly after

Typically this would trigger a

hotspot (Flow rate)

Demand Capacity Balancing - Flight prediction ListFlights identified that were

predicted to arrive when

airborne delay was greatest.

We Hypothetically delayed

these flights to ensure they

would enter the stacks

slightly later than planned

Algorithm issued Target

Times that were back

calculated into iCTOT as

today.

Intelligence applied to assign

TTA’s based on equitable

ops.


Impact of the changes analysed

As can be seen from

the image, the peak

has been reduced

from 19min to 16.4min


(1) Currently applying Mach speed reductions for AMAN tactical flow management

(2) Apply TTA for AMAN tactical flow management

(3) Apply TTA for AOP sequencing; Apply CTOT for AOP sequencing

(4) Refine sequence for ATC flow management; TTA revision

(5) Refine sequence for ATC flow management; TTA revision

(1) Currently applying Mach speed reductions for AMAN tactical flow management

(2) Apply TTA for AMAN tactical flow management

(3) Apply TTA for AOP sequencing; Apply CTOT for AOP sequencing

(4) Apply CTOT to European Deps when needed to allocate delay or smooth arrivals. Apply TTA to long hauls to improve

punctuality or allocate delay/smooth arrivals
