Flight Efficiency Opportunity generation A use case for the GRRT tool

Predictability 2

What is the GRRT tool?

GRRT = Group ReRouting Tool A tool

to change the routeor propose routes for flights

Predictability 3

Group ReRouting Tool : where can we use it ?

Flexible tool : used for multiple purposes and contexts Strategical : e.g. prepare for an exceptional event Pre-tactical : e.g. prepare PREDICTed traffic for the next days Post-ops : e.g. study possible network improvements, produce KPIs, ... Tactical : e.g. Flight Efficiency Opportunity generation

GRRT execution under user control : “one shot, interactive” unattended : “run it automatically, every day, at a certain time”

One use case is the Flight Efficiency Opportunity program: the aircraft operator provides the information needed

to setup (one or more) daily unattended automatic GRRT.

Predictability 4

How is a GRRT executed ?

1. Retrieve the Group of flights to reroute

2. For each flight, make a list of possible alternative routes from automatically daily maintained route catalog (> 200_000 routes) using the path finder : dynamic route generation

3. Compute the “cost” of each alternative route “cost” is based on AO chosen cost criteria

e.g. route length, fuel, route charges, …

4. If a significantly cheaper route is found, inform AO of the possible improvement:

Flight is marked as having an opportunity in CHMI/NOP flight list Operational log contains the details : field 15, changes in route length, …

Flight Efficiency : GRRT(s) registration info(to be provided by AO)

1. When and how to select the Group of flights for this GRRT When to run this GRRT e.g. 09h00 your AO list e.g. TCX CFG TCW VKG ART MYX The take off time period e.g. from 11h00 till 17h00

2. Route generation uses standard criteria (route catalog, path finder)

3. Give your cost specific parameters to evaluate the route Desired minimum (total) improvement

Example : -100 Euros reduction minimum needed

Detailed cost criteria Example: 1 minute of delay = 40 Euros

1 ton of fuel = 850 Euros1 minute flying time = 10 Euros

Predictability 6

Cost criteria balancing by GRRT

GRRT automatically searches the route with the cheapest total cost Cheapest opportunity might deteriorate some criteria :

deteriorate some criteria (e.g. ground delay, route length)but improve some others (e.g. flying time, fuel)

if in total it is more efficient (cheaper)

Example: 1 minute of delay = 40 Euros1 NM = 20 Euros

+ 5 minutes delay, -20 NM : cheaper +200 -400 = -200 + 5 minutes delay, -5 NM : more expensive +200 -100 = +100 -15 minutes delay, +10 NM : cheaper -600 +200 = -400 What if huge delay (e.g. strike):

-200 minutes delay, +350 NM : cheaper -8000 +7000 = -1000 To avoid excessive balancing, specify a limit deterioration :

1 NM = 20 Euros limit deterioration: 100 NM

GRRT dynamic route generation and evaluation

Done using up to date information: Last meteo information (wind) Last minute opening (or closing) of routes Based on current/detailed ATFCM situation (delays, closures)

=> generate opportunities that allows to benefit from a shorter route if the delay situation improves on this route from a shorter route thanks to a last minute opening from route that avoid severely regulated area from better route efficiency (fuel, flying time) thanks to up to date wind …

Predictability 8

GRRT : real operational case(internal screen to input AO params)

Predictability 9

Result (similarly visible in CHMI/NOP operational log)

current route cost: 2943 (3043)(-100) + 0 + 496 + 0 + 2007 + 540

interesting cheapest route cost: 2800(0) + 0 + 452 + 0 + 1808 + 540

Other routes (less interesting and/or more expensive) followsordered by cost

interesting route and its TOT validity

Predictability 10

Improvement in NM 18.0 : flexible Group Flight selection(in internal screen to input AO params)

Wildcards on any column of the GRRT Selection tab

Allows to have different GRRTs (and cost criteria) Per aircraft type group e.g. for small/medium/big aircrafts For some specific city pairs For regulated flights or non regulated flights For flights having a big delay ….

Predictability 11

Other improvements in NM 18.0

Simplified oplog in CHMI/NOP Only showing the current route and the interesting routes

(more expensive routes not shown)

Only showing the criteria values (e.g. NM, Kg, minutes, …) (corresponding EUROs values not shown anymore)

Easier input of a GRRT to be executed several times per day

GRRT for Flight Efficiency opportunity: summary

Daily significant benefits (operational, environmental, …)reported by participating AOs

GRRT is a sophisticated/flexible/efficient tool but it is complex => we set it up for you !

Contact us to discuss your wishes/specific needs/… We prepare and activate your set of GRRTs They run automatically everyday for your benefit

Less fuel, less delay, shorter flying time, …
