1 NM USER FORUM 2014 Philippe Waroquiers NM Head of NeOs Team Flight Efficiency Opportunity generation A use case for the GRRT tool

2 2 What is the GRRT tool?  GRRT = Group ReRouting Tool  A tool to change the route or propose routes for flights

3 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.

4 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, …

5 5 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 GRRTe.g. 09h00  your AO liste.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 Euros 1 minute flying time= 10 Euros

6 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 Euros 1 NM= 20 Euros  + 5 minutes delay, -20 NM : cheaper = -200  + 5 minutes delay, -5 NM : more expensive = +100  -15 minutes delay, +10 NM :cheaper = -400  What if huge delay (e.g. strike): -200 minutes delay, +350 NM :cheaper =  To avoid excessive balancing, specify a limit deterioration : 1 NM= 20 Euroslimit deterioration: 100 NM

7 7 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 ……

8 8 GRRT : real operational case (internal screen to input AO params)

9 9 Result (similarly visible in CHMI/NOP operational log) current route cost: 2943 (3043) (-100) interesting cheapest route cost: 2800 (0) Other routes (less interesting and/or more expensive) follows ordered by cost interesting route and its TOT validity

10 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  ….

11 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

12 12 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, … Questions ?
