AGUSTA-WESTLAND AND EUROCOPTER WILL BE THE LEADER OF THE INTEGRATED PROJECT
MANY OTHER INDUSTRIES, RESEARCH CENTRE AND UNIVERSITIES WILL BE ALSO INVOLVED (EUROPEAN AND NOT)
6th FRAMEWORK PGM
SUMMARY
The VTOL Aircraft in the ATM
The Public Acceptance
TILTROTOR IN ATM
THE TILTROTOR (T/R) AS THE SOLUTION FOR THE CONGESTION PROBLEM
T/R CAN OPERATE IN ALL WEATHER CONDITIONS FROM AIRPORTS OR VERTIPORTS STRATEGICALLY LOCATED TO PROVIDE CONVENINET ACCESS TO OTHER TRANSPORTATION SYSTEMS(TRAIN STATIONS, HIGHWAYS…)
VERTIPORTS: NEW ECONOMICS AND BUSINESS CENTERS
T/R CAN PROVIDE AIR SERVICE INTO HUB AIRPORTS TO FEED THE LARGER, LONG DISTANCE AIRCRAFT (A ROLE THAT COMMUTER TURBOPROPS PLAY TODAY)
T/R COULD DISPLACE A LARGE PERCENTAGE OF THE SMALL AIRPLANE FLIGHTS AND FREE UP THE SLOTS FOR LARGER AIRCRAFT
PART OF THE MONEY USED FOR NEW AIRPORTS COULD BE USED TO DEVELOP THE T/R SYSTEM: IT WOULD COST LESS
MORE OPTIONS FOR PASSENGERS DEPARTURES

ACOUSTIC CAUSES
Rotors noise
Blade vortex interactions (BVI)
Active blade controls (flaps, HHC, IBC…)
Flying at heights greater than today (3000 ft above cities; 5000 ft above rural areas)
2005 Europe/US International Aviation Safety Conference, Cologne 7-9 June
PUBLIC ACCEPTANCE
VIRTUAL NOISE
Is it controllable?
Different noise respect to the more common fixed wing noise
Increase of the level of dB:
+15/20 dB(A)
Better public relations: understand the concerns & needs of each other
Heliports in noisy area
The Community Says:
NEW RULES
Nacelle Tilting Mechanism
Flight Quality Requirements with FBW System
Handling Qualities Criteria
NEW RULES
Iterative Certification Process for a Live Certification Basis
FLT TEST
TEST RESULTS
AIRPORT OPERATIONS
Objective: Remove IFR R/C & T/R from runway traffic by using their specific, non dependent, procedures
Advantages:
for the pilot: shortened approaches (time / fuel savings)
for the controller: removes “slow traffic” from RWY approach (easier A/C-R/C-T/R separation)
for airport neighbours: less noise thanks to higher approach routes and steep final leg
for airport authorities: adds movements without contribution to RWY congestion (passenger throughput)

AIRPORT OPERATIONS
Visual Manoeuvre
Standard Separation
A/C Separation
R/C Separation
R/C Go-around
AIRPORT OPERATIONS
Combined use of Helicopters and Tilt-Rotors for Hub Feeder operations can increase passenger throughput
SNI potential for future R/C operations
NASA / Boeing Studies
+20% to + 30%
passenger throughput
Provides 50% as much delay reduction as a new runway (NASA study)

OPEN QUESTIONS
Which are the actions that Industries, Operators, Associations, Regulations Agencies should give themselves in order to reach the goal of the introduction of the VTOL aircraft in the ATM?
In the case of an SNI approach, what should be the minimum separation with the other traffic?
What is the required navigational performance of the SNI approach procedure and how sensitive is this procedure to items as weather, system failures…?
What are the requirements in terms of visually acquiring, observing and guiding rotary-wing traffic to separate them from other IFR fixed-wing traffic by the control tower?
Does the traffic controller need special equipment, algorithms, etc. in order to reduce the mental stress or the conflict-solving predictive capability?
…
2005 Europe/US International Aviation Safety Conference, Cologne 7-9 June
THE AGUSTA ADVANCED TILTROTOR ERICA IS A STEP FORWARD FOR THE AIR TRANSPORT
THE RUNNING CRITICAL TECHNOLOGY PROJECTS ALLOW TO REINFORCE THE EUROPEAN KNOWLEDGE IN THE DOMAIN
THE 6th EUROPEAN FRAMEWORK PROGRAM WILL CONTRIBUTE TO THIS GLOBAL OBJECTIVE WITHIN A LARGE PARTNERSHIP
INDUSTRIES, OPERATORS, ASSOCIATIONS, REGULATION AGENCIES SHOULD GIVE THEIR EFFORT IN ORDER TO INTRODUCE THE VTOL IN THE ATM
