1 4. FEB 2015 E-TAXI: win-win for airlines and airports? Libor Kurzweil, Director of Safety and Quality, Prague Airport IATA Aircraft Taxiing Systems Conference Coral Gables, Miami, FL February 2015

2 Czech Republic country in the heart of Europe 2 The Czech Republic is a small country in the central Europe, which has an appeal for visitors. Thanks to its location at the crossroads of various cultures, the Czech Republic has countless cultural and historical points of interest. These destinations attracts a high number of foreign tourists every year.

3 Prague Airport Václav Havel Main Gateway to the Czech Republic 3 LKPR / PRG 11 km distance from the downtown 11 million PAX in 2014 (max. 12,63 mil. in 2008) 125k MVTS in 2014 (max. 179k in 2008) 46 MVTS per hour of declared capacity RWY 06/24: 3715x45 m RWY 12/30: 3250x45 m Terminal 1: Schengen Terminal 2: Non-Schengen Terminal 3: General Aviation Terminal 4: Military 2 cargo terminals 5 APRONs 90 aircraft parking stands A380 ready

4 My journey to MIA PRG with A320 CDG 4½ min., no queuing (CDM) 8½ min. CDG with A380 JFK 9½ min. + 4 min. queuing 6 min. + tow to the Gate JFK with M88 MIA 9½ min min. queuing 3¼ min. 6

5 E-TAXI BENEFIT ANALYSIS

6 E-TAXI benefit analysis 1 Landing & Taxi-in E-taxi is possible when the engines cool down. Mandatory cool-down time: 2 min. on idle (RR engines 3 min.) Recommended cool-down time: 3 min. Taxi-in PRG: 2 to 5 min., average 3,5 min. 8

7 E-TAXI benefit analysis 1 Landing on 24 & Taxi-in T Reverses clsd Engines idle Landing T+40 s RWY vacated No chance for E-taxi E-taxi T+2 min Cooled down Ready for E-taxi RESULT Depends on combination of the RWY in use and aircraft stand, E-TAXI can be used 0 to 3 min of Taxi-in time. No significant benefit for PRG 9

8 E-TAXI benefit analysis 2 Docking & Handling start E-taxi technology may accelerate the initiation of the handling process by a few seconds. There is no danger zone around the engines Good benefit for airports, but the ground staff must recognize that it is an E-taxi movement, otherwise they can t benefit. 10

9 E-TAXI benefit analysis 3 Side loading Speeding-up the turn-round is attractive for LC carriers, in case the airport fees remains the same. Here the Gates require 20 % more concrete, the 2nd jetty for each stand = high investments => To be paid by airlines and passengers 11

10 E-TAXI benefit analysis 4 Power back 1. Ground staff nor the surrounding traffic is not affected by the Jetblast. 2. No waiting for disconnecting the tractor. 3. Taxiing can be initiated by an average of 2,5 minutes faster. Good benefit for airports For PRG evaluated in ARCPort simulation: APRON throughput improved by +2,7% 12

11 E-TAXI benefit analysis 5 Multiple ops on same Taxilane Due to a Jetblast, a Safety zone of 100 m is required between two pushing aircraft. With E-TAXI we could move at the same time as many aircraft as we want! Good benefit. 13

12 E-TAXI benefit analysis 6 Construction sites E-taxi offers greater safety for construction activities carried out in proximity to the aircraft. Due to the fact that not 100% of Aircraft will have E-taxi, this advantage is impossible to use. Safe distances must still be determined in the same way as now, with regard to aircraft with the main engines running. Procedures remain unchanged. No significant benefit for airports 14

13 E-TAXI benefit analysis 7 Vehicles crossing TWYs On the APRON there are crossings of TWYs and Service roads for vehicles. Vehicle drivers are obliged to stop, give way to Aircraft and wait until they get at least 100 m distance from a Jetblast source. In the case of E-taxi there is no danger of Jetblast and vehicles could cross much earlier. But, the pre-requisite is a recognition of E-taxi by the driver. The technology is not visible on the plane at first sight. It has to be visible, otherwise good benefit for airports is lost. 15

14 E-TAXI benefit analysis 8 Remote Deicing During a de-icing the engines are usually running. The deicing time may vary from 5 to 40 min: E-taxi may save a lot of fuel, CO2 and noise. Deicing will be safer for personnel present at the Deicing stand. Good benefits for airports 16

15 E-TAXI benefit analysis 9 Taxi-out E-taxi is possible until there is a need to warm-up engines. Warm-up time: 2 min. mandatory 3 min. recommended 10 to 15 min. recommended after 6 hrs stay Taxi-out PRG: 2 to 5 min. average 3,5 min. Mo Not much queing thanks to CDM 17

16 E-TAXI benefit analysis 9 Taxi-out T-1 min Engines running HP 24 T-2 min T-3 min T-4 min Starting 2. engine T-5 min Starting 1. engine E-taxi RESULT With RWY 12 or 24 in use there is no time for E-taxi. With RWY 06 and 30 possible use of E-taxi is 1 to 2 min. Almost no benefit for PRG 18

17 E-TAXI benefits for PRG airport in numbers LKPR / PRG ARR DEP Usage of RWY direction 63% 30% 5% 2% 63% 30% 5% 2% Total taxi time [s] E-TAXI taxitime [s] Percentage of E-TAXI A/C 67% Average use E-taxi / 1 movement [s] 68,96 5,56 No ARR/DEP yearly E-taxi engine-hours / year Fuel savings [ton] 2 950,09 237,89 N2O Savings CO2 Savings [ton] 7 880,16 635,43 Benefit for deicing yes Increased throughput of APRON yes Lost income: pushbacks Lost income: towings Lost income total -2,38 mil. EUR EUR -2,847 mil. EUR yearly (71,1 mil. Kč) 19

18 MY FOUR RECOMMENDATIONS TO VENDORS Make it visible. The staff must recognize E-taxi in use, otherwise they can t benefit. Illumination, flashlight, Make it simple. Pilots are busy when taxiing, new workload = less situational awareness & risk of an incident. Consider automatic switching from/to E-taxi Want to enhance Safety? Develop anti-collision system with sensors and automatic braking Want to help pilots even more? GNSS technology becomes precise and reliable: Ultimate vision: Automatic power-back and E-taxi? 20

19 SAFETY

20 E-TAXI Procedures Possible airport operation of the future: mixed traffic of Taxibots, WheelTugs, EGTSs, APTs and conventionally taxiing aircraft All must live side by side SAFELY 22

21 SAFETY BENEFITS OF E-TAXI No Jetblast issues No FOD intake Safety of staff Less APRON vehicles 23

22 Target audience: ramp personnel, pilots, drivers Cizí předměty FOD Safety.. briefs FOD - Foreign Object Debris Issued: February Tři jednoduché zásady, které významně napomohou zmírnit riziko FOD. 1. Pracujte s očima otevřenýma. Spatříte-li cizí předmět na odbavovací ploše, prioritně jej odstraňte bez ohledu na to, kdo nepořádek zavinil. 2. Na odbavovacích plochách jsou instalovány žluté kontejnery, speciálně určené pro drobné předměty FOD. Větší předměty zajistěte a hlaste dispečinku Řízení provozu letiště, tel Přemýšlejte, kde odstavujete své MMP. Nezapomeňte, že i toto vozidlo, zanechané na odbavovacím stání, je FOD. Vozidlo odstavené na odbavovacím stání je překážkou! Využívejte výhradně přidělená parkovací místa. Three simple rules that help to mitigate the risk of FOD. 1. Work with your eyes open. If you see a FOD on a movement area, remove it with priority, regardless of who has caused the particular debris. 2. There are yellow bins installed on the APRONS, designated to small sized FODs. Larger FODs are to be secured and reported to Airfield OPS dispatcher, tel Think twice where do you park a GSE. Don t forget, that even this GSE, parked on an aircraft stand, is a FOD. A GSE left on a stand blocks a handling process! Use the dedicated parking stands only. Pozitivní příklad Ramp Agent p. Daniel Vašut z Menzies Aviation informoval Safety o nálezu FOD, poškozeného držadla víka kanálu v prostoru odbavovacího stání. FOD byl díky tomu okamžitě odstraněn a nezpůsobil zranění či škodu Co patří mezi FOD? odpadky, součástky, klíny, kužely, zapomenuté nářadí, pytle s odpadem po handlingu, špatně zaparkovaná MMP a kontejnery, poztrácená zavazadla, obecně jakýkoliv předmět, který na plochu nepatří, anebo není na svém místě What is considered as a FOD? garbage, parts, blocks, cones, left tools, trash from handling, GSE or containers improperly parked, left luggage, Generally, any object not intended to be on a movement area or not at its own place Positive example Ramp Agent Mr. Daniel Vašut from Menzies Aviation reported a FOD, damaged handle of a drainage cover, found on an acft stand. Thanks to the report the FOD was removed immediately and did not cause injury or damage Created 2013 by Prague Airport, Safety Management Department Feel free to distribute. us if you want to be added to the distribution list or removed safety@prg.aero

23 Target audience: Ramp personnel Safety.. briefs Issued: March Odpojení letadla po vytlačení Zaznamenali jsme již několik případů, kdy posádka letadla zahájila pojíždění ještě před odpojením sluchátek interkomu ramp agentem. POZOR! Posádka má z kokpitu letadla omezený výhled, proto se snažte být mimo její zorné pole co nejkratší dobu. Sledujte motory letadla. Nesnažte se schovávat před nepříznivým počasím pod letadlem se spuštěnými motory. Dodržujte komunikační pravidla a předepsané fráze včetně potvrzování (readback). V případě sebemenších pochybností si vyžádejte zopakování či potvrzení instrukce. Mějte na paměti, že letadlo se po odpojení tahače může pohnout dopředu. Pokud dojde k pohybu letadla, ihned upozorněte posádku! Vyjmutí steering pin proveďte až po spuštění všech motorů! Světelnou signalizaci parkovací brzdy (na některých typech - např.airbus) berte jen jako pomůcku - nenahrazuje předepsanou komunikaci. Disconnecting the A/C after pushback We have recorded several incidents where flight crew started taxiing before disconnection of the headset by the Ramp agent. WARNING! The crew has a limited view from the aircraft, so minimise the time you spend out of their field of vision as much as possible. Watch the aircraft engines. Do not attempt to hide from bad weather below the plane with the engines running. Strictly follow the communication rules and use the correct phrases including confirmation (readback) - in case of even the slightest doubts, ask crew to repeat / confirm the instruction. Keep in mind that the aircraft can move forward after disconnecting the tractor. Immediately notify the crew if the aircraft moves! Do not remove the steering pin until all engines are not running! Use the parking brake indicator (on certain types - e.g. Airbus) as an aid only - it doesn t replace the proper communication.
