3 The WheelTug System

4 Wheels: Head to Head

5 Conventional Taxi vs. WheelTug Without WheelTug With WheelTug Taxi In Engine active from landing to terminal Taxi In WheelTug active from landing to terminal Tug required for pushback from gate WheelTug to/from gate No tug required Engine active from terminal to takeoff WheelTug active from terminal until warmup Taxi Out Taxi Out Engine active from warmup to takeoff (WheelTug can continue operations during engine start)

6 Engines/APUs On Engine & APU Usage Cumulative Time Engines/APUs On Cumulative Time Engines/APUs On Cumulative Time The average US narrowbody taxis for 21 min/cycle Engine warm-up & cool-down requires 2-3 minutes each Single-engine taxi keeps the APU on to avoid cross-bleed starts Dual-Engine Taxi Single-Engine Taxi WheelTug Taxi Taxi Minutes Taxi Minutes Taxi Minutes 0 Engine Time/Min APU Time/Min Engine Time/Min APU Time/Min Engine Time/Min APU Time/Min Total Engine Time Total APU Time Total Engine Time Total APU Time Total Engine Time Total APU Time

7 Key WheelTug Features Rapid retrofit - installable using just overnights + 2 shifts for the landing gear swap Easily Uninstalled removes in 2 shifts, so not a permanent feature Fits into existing wheel well space Power from the APU Minimal (read-only) connection to aircraft data Master Minimum Equipment List (MMEL) system does not need to function for aircraft dispatch Cockpit, wire harness, software and ICE Box are zero maintenance items, unless flagged Wheel Package will be inspected with tire changes Wheels and subcomponents will be replaced when inspections merit it

8 WheelTug on Display An in-the-wheel, APU-powered, WheelTug system was operated in Prague in 2012 and can be viewed at media.wheeltug.com Snow and ice operation was demonstrated in 2010

9 A320 Turning Traction Because there is twice as much weight on half of the wheel area, the traction is the same Breakaway Torque 2012 Prague tests demonstrated that when turning sharply, only 50% of the straight-line torque was required

10 A WheelTug Pushback 2 ground crew, using existing approved powered pushback procedures, visually (and/or with comms) guiding pilot Boeing Simulator Management Services has been developing crew training: 45 minutes on CBT WheelTug is also working with Prague Airport and Czech Air Navigation Services. Ongoing constructive discussions with ADP, Schiphol, Swedavia, ACI, Eurocontrol, ICAO and IATA Ground Handling (In the future, optional use of ground camera systems (already approved and available for 737s and A320s) can enhance pilot situational awareness)

15 Savings Per Cycle Savings/Year Fuel Savings/Cycle $2,500 $4,500,000 $200 $4,000,000 $2,000 $3,500,000 $150 $100 $1,500 $1,000 Twist ($1670) $3,000,000 $2,500,000 $2,000,000 $50 Other ($60) $1,500,000 $0 vs. Dual Engine vs. Single Engine Fuel-Savings Only $500 $0 Time ($390) Pushback ($100) Fuel ($100) Total Savings/Cycle vs. Single-Engine Taxi Engine ($40) $1,000,000 $500,000 $0

16 Savings Per Cycle Pushback Savings Pushback Savings/Cycle WheelTug eliminates pushback tugs, removing pushback costs & associated risks $2,500 $4,500,000 Pushback costs typically include capital, personnel, maintenance, fuel, & incident insurance (such as below) $2,000 $4,000,000 $3,500,000 Pushback costs are typically >$100/cycle $1,500 Twist ($1670) $3,000,000 $2,500,000 $1,000 $2,000,000 Other ($60) $1,500,000 $500 $0 Time ($390) Pushback ($100) Fuel ($100) Total Savings/Cycle vs. Single-Engine Taxi Engine ($40) $1,000,000 $500,000 $0

17 FOD & Engine Wear Environmental engine wear & FOD leads to damaged blades

18 Engine Maintenance Expense Lessors calculate maintenance reserves based on airports of operation This is because most particulates and debris damage the engine on the ground Maintenance costs are $175/block hour/engine^ Engine Environmental Distress Map (Aircraft Monitor) WheelTug saves: $21/cycle vs. single-engine taxi and $43/cycle vs. dual engine taxi ^ Source: Analysis of Aircraft Commerce Owner s & Operator s Guide: 737NG Family

19 Efficiency Loss Fuel Efficiency Improvement Typical fuel efficiency loss is 4% over 8 years 80% of this loss is attributable to taxi Annually 0.4% in efficiency is lost due to taxi Annual Cost of Efficiency Loss Each year of taxi use costs $14,400/engine/year in lost fuel efficiency (w/fuel cost of $7.2M/yr/aircraft) Cost per Minute At a 8% discount rate and average of 4 years until overhaul, each year of taxi costs $51,500 in future fuel efficiency. Average aircraft taxi for 35,910 minutes/year (1700 cycles * 21 minutes), so each minute is worth $1.43 in fuel efficiency improvement. WheelTug saves: $20/cycle vs. single-engine taxi and $42/cycle vs. dual engine taxi

20 Savings Per Cycle Savings/Year Engine Savings/Cycle $2,500 $4,500,000 $90 $4,000,000 $80 $70 $2,000 $3,500,000 $60 $50 $1,500 Twist ($1670) $3,000,000 $2,500,000 $40 $30 $20 $1,000 Other ($60) $2,000,000 $1,500,000 $10 $0 vs. Dual Engine vs. Single Engine Engine-Savings Only $500 $0 Time ($390) Pushback ($100) Fuel ($100) Total Savings/Cycle vs. Single-Engine Taxi Engine ($40) $1,000,000 $500,000 $0

21 Taxi-in/Out Time Savings No waiting for a pushback tractor No need to disconnect from a towbar or lift tug For gateless operations, engines can be started during taxi out On arrival, ground crews do not need to wait for engines to spool down Turnaround Delays (seconds) Stage Gateless Gate/Towbar Gate/Lift Tug WheelTug Est. average delays (for tractor/marshalling or disconnect) Tug-disconnect & engine start Engine start & checklist (gateless) Wait on taxi-in Total

34 Value of Extra Flight Time Use of Extra Flight Time By making additional time available WheelTug can: Enable new shorter cycles Enable usage of existing spare time that is currently too short to add a full cycle Enable longer routes in place of shorter ones Value of Extra Flights New cycles in the same operating day do not generally require additional staff or fixed aircraft costs Revenues and costs vary widely by airline, but each additional cycle is worth $4,700 using: Average revenue of $15,200 Variable flight costs of $10,500 And staff/fixed aircraft expense of $4,500 Value of Extra Flight Minutes Using a block + turn time of 152 minutes, we can see a value for time of $31/min

35 Value of Faster Turnarounds Impact of Time on Fares Passengers, especially business passengers, are sensitive to time lost With WheelTug pushback, an airline can offer much faster pushbacks and starting rolls With the Twist, an airline can offer: double-fast boarding (much less waiting), sit-and-go (much less waiting for pushback), stop-and-go (much faster deboarding, particularly for those in back). Value of Time Professor Silke Forbes compared fares at LaGuardia after delays caused by the AIR21 Act in 2000 with fares prior to the act and with fares at unaffected airports. It was found that: A minimum delay cost of $0.77/min/passenger ($0.83 in 2013 dollars) for connecting passengers A maximum delay cost of $2.44/min/passenger for direct passenger on competitive routes The FAA uses a value of $0.54 to $0.81/min/passenger ^ when CPI adjusted to 2013 dollars WheelTug uses a value of $0.77/passenger/min to calculate the impact of faster turnarounds on fares Values will be higher for more competitive business routes For a typical load of 115 passengers, the total impact on fares is $88.55/minute Combining extra flight time and fare impacts, time is worth $119/minute ^ Economic Values for FAA Investment and Regulatory Decisions

36 Time Savings/Cycle Savings Per Cycle Savings/Year $2,500 $2,500 $4,500,000 $4,000,000 $2,000 $2,000 $3,500,000 $1,500 $1,500 Twist ($1670) $3,000,000 $2,500,000 $1,000 $1,000 $2,000,000 $500 $0 WheelTug Pushback WheelTug Twist Time Savings Only vs. lift tug $500 $0 Other ($60) Time ($390) Pushback ($100) Fuel ($100) Total Savings/Cycle vs. Single-Engine Taxi Engine ($40) $1,500,000 $1,000,000 $500,000 $0

38 Implementing the Twist WheelTug sees the Twist as a conditional benefit not like pushback or fuel savings. The Twist will require: Regulatory approval Procedure changes Airport approval Where could the Twist be done? The Twist fits in a wide-body gate, and at narrow gates with extra room. But jet bridges would require change At some narrowbody gates, the Twist could be done now, with existing jet bridges if there are two available adjacent gates WheelTug estimates that, assuming airport and regulatory approvals are granted, the Twist could be used in 30% of situations immediately, and 30% more within two years

42 Personal Injury With WheelTug, no ground personnel need to approach the nose gear at all No towbar connection No comms linkup required No NLG safety pins to remove or install Ramp Worker Injuries and Costs (source: Flight Safety Foundation) 9 injuries per 1000 departures 10 injuries per 100 FTEs per year (Coal mining has 3.6/100 FTEs per year) Personal injury costs of $350,000/year/aircraft We estimate a 15% reduction in injuries, providing savings of $52,000/year and $31/cycle

43 Other Savings: Brakes Pilots ride the brakes today to counteract constant engine thrust Carbon brakes wear poorly when cold Industry measures taxi out brake wear at 79%, and landing at only 19% WheelTug should reduce brake wear by at least 40%. Brakes would only be counteracting engine thrust at the end of the taxi, when engines are started Carbon Brake Savings Carbon brake replacement cost $144,000 Replacement timeline 18 months Cost/year $96,000 Wear attributed to braking against engines ~40% Savings/Year (4.5 cycles) $38,400

44 Other Savings: Emissions Emissions reductions can improve an airline s image with: Customers Airports Regulators Environmental groups & media Emissions/Cycle Prague Airport won IATA s Eagle Award for Most Deserving Airport in the world crediting support for WheelTug development! WheelTug has just won the 2013 ATW Eco-Technology of the Year Award! Emissions Credit Value Kg emissions/lb of fuel 1.62 lbs fuel saved vs. single-engine taxi/cycle 245 Value/1000 kg of emissions (point carbon) $7.82 Value/cycle $3.12 Value/Year (4.5 cycles) $5,050

45 Heating (Stamina) WheelTug will generate heat during operation, although our motor technology has a much higher heat tolerance than do most other motor technologies The system does NOT require any cooling lines, or use any fans and we have no brake heating to worry about. But there are thermal limits, set, for example, by the wheel WheelTug is designing for 95% availability, with airline concurrence (since bulk of savings are early in each cycle) In the event that engines need to start sooner (because of temperature), the impact on savings is marginal. There is no operational downside

46 OTHER (NON-QUANTIFIED) BENEFITS ANALYSIS

47 Landing Gear Wear Towbar tractors have their own inertial mass, and exert nonlinear damage on aircraft nose gear WheelTug is built into the Wheel, and thrust is smoothly applied

48 Increased Throughput Without disconnects or engine warm-ups, jets move forward as soon as they finish taxiing back. This means ramps are not blocked by immobile aircraft

49 Increased Throughput Due to elimination of jet blast, engine noise & ingestion risk

50 Increased Throughput Due to elimination of jet blast, engine noise & ingestion risk Higher gate throughput Service vehicles, passengers and personnel can operate around aircraft as soon as the airplane comes to a stop Higher Airport throughput Safety margins in taxi can be reduced allowing more vehicles in the same space Pushback time savings means aircraft don t block the taxiway for others especially in cramped ramp areas

52 Air Quality Smog chamber experiments indicate that photo-oxidation of aircraft emissions produces significant amounts of secondary PM, which, under typical summertime conditions, exceed the primary emissions within minutes of the exhaust leaving the engine. Therefore, secondary PM must be considered when evaluating the influence of aircraft emissions on local and regional air quality.

53 Air Quality Without WheelTug Air Conditioning Intake With WheelTug With WheelTug, cabin air quality improves under certain conditions Pilots complain of as many as five fume events per week and sometimes pursue legal action

54 New Slot Creation In airports with morning noise curfews, engines can t start until curfew lifts With WheelTug, loaded aircraft can taxi to the runway prior to curfew This can add 5-10 additional daily morning take-off slots per runway First-morning flights are the most valuable for business travelers Premium slots sell for $3 million or more Aircraft Positions when curfew is lifted WheelTug Aircraft Non-WheelTug Aircraft

60 WheelTug s Competitive Advantages 1. Unique Technology 2. Simpler Solution, Faster to Market 3. Patent Protection It s not easy to package the elephant in the nose wheel. Until WheelTug did it, everyone knew it could not be done! Competitors are focused on the main gear WheelTug nose gear location eliminates brake complexity and heat interference; enables faster certification. EIS 2014 Safran/Honeywell EIS L3/Crane EIS OUT DLR designed a demonstrator using fuel cells Airbus continues to examine mainwheel approach 85+ WheelTug patents pending or issued, + international coverage In 2009, WheelTug s parent company met and won a patent challenge

61 Comparing E-Taxi Solutions Main Landing Gear vs. Nose Landing Gear Fleet Retrofit Advantage? Nose Landing Gear A main landing gear E-taxi solution must work around brakes, sensors and other equipment. It is also further from the cockpit and E&E bay, requiring longer wire runs. A main landing gear system will be hard to integrate into the production line and even harder to retrofit on existing aircraft. As a simple retrofit, WheelTug is easy to remove, enabling customers to be compatible with lessor requirements. Commercial Value Advantage? Nose Landing Gear The nose landing gear won t heat the brakes. This enables the Twist, saving minutes of taxi time. A main landing gear solution will be more expensive to install and harder to remove, creating commercial costs with its implementation. Safety & Certification Advantage? Nose Landing Gear A drive system on the nose landing gear won t heat brakes or produce EMI that can confuse anti-skid sensors. It is very hard to prove that an ipad can never interfere with aircraft navigational equipment. It will be far more challenging to prove that a powerful EMI source next to flight critical sensors will never have a safety impact. What about traction? We ve demonstrated traction in rain, on oil, and through snow.
