2. DIRECTION TECHNIQUE CERTIFICATION Paris, 14 - 15 April 2008 SL2008-13 ASAS TN2 Workshop 080414.ppt Business Aviation Specificities CRUISE OPERATIONS BusJets operate mostly above airliner traffic Large BusJets operates at high altitude (at and above FL 410) Low density traffic, with possibility to operate on free routes in climbing cruise mode Possibility to develop a unique sector all over Europe BusAv operate in all classes and types of airspace in the world TERMINAL AREAS & AIRPORTS Operations from local airports BusJets operate from short runways (a Falcon 7X lands on a 4000 ft runway) Most of these TMAs are Class G airspace and so not controlled Safety of operations is a real concern Operations from Hubs BusAv must "adopt a low profile" Development of wake vortex free approaches

3. DIRECTION TECHNIQUE CERTIFICATION Paris, 14 - 15 April 2008 SL2008-13 ASAS TN2 Workshop 080414.ppt Business Aviation Wishes THAT ALL AIRSPACE BE “MANAGED” ATC role is essential for the safety of operations But ATC must move from a "control of the airspace" to a "management of the airspace" Pilot must be in a position to "avoid collision" Collision avoidance no longer based on "see & avoid" but on systems and technology Aircraft "separation & collision avoidance" based on safety objectives No longer based on the applications of operational rules THE SOLUTIONS ADS-B everywhere ADS-B "primary means of surveillance" to allow development of ASAS ADS-B adapted to the airspace : 1090ES, but also UAT (local airport) and may be VDL4 ATC Management of airspace Location of all objects in the air (all flying machines equipped with position reporting device) "Virtual remote tower" where there is no physical tower to manage the operations Dynamic management of approaches & take off airspace areas UAT : Universal Access Transceiver

4. DIRECTION TECHNIQUE CERTIFICATION Paris, 14 - 15 April 2008 SL2008-13 ASAS TN2 Workshop 080414.ppt Business Aviation Specific ASAS Needs GENERAL REMARKS Has to be considered as additional needs compared to Air Transport ones BusAv specific ASAS needs are mainly relative to "low aircraft density airspace" High altitude, Remote area, Local airport TMAs ROLES OF ATC & PILOTS ATC manages the airspace Determines the "potential conflicts", separates the aircraft and delegates "basic separation" ATC delegates the separation each time the pilot is in a better position to perform separation In term of workload, in term of situation awareness (climbing cruise) The ASAS mode can be defined as "Cooperative Self Separation" ASAS one Pilot assures the safety of the separation & collision avoidance In cruise pilot controls the separation (horizontal vertical and vortex) and avoid collision (TCAS) In local TMA pilot makes a combination of surveillance, separation & collision avoidance

6. DIRECTION TECHNIQUE CERTIFICATION Paris, 14 - 15 April 2008 SL2008-13 ASAS TN2 Workshop 080414.ppt  The vertical location of the Intruder and its trend ASAS Symbology 000 5 SEPARATION F7X F-WIDE 3 nm 03:30 NTS 62.5 nm 08:00 11 44 Z F M S 1 ASAS : Airborne Separation Assistance System ADS-B : Automatic Dependance Surveillance Broadcast X1 ADS-B will provide :  An accurate position of the Intruder  The Track of the Intruder  The Ground Speed of the Intruder and so the intruder relative course  Appropriated route change might be proposed to the pilot

7. DIRECTION TECHNIQUE CERTIFICATION Paris, 14 - 15 April 2008 SL2008-13 ASAS TN2 Workshop 080414.ppt Modes & Symbology RELATIVE MODE DISPLAY Allows a permanent monitoring of the intruder trajectory Adapted to "one to one separation", but allows detection of intruders in course collision SPECIFICITY OF CLIMBING CRUISE Above FL 410 minimum separation is 2000 ft In climbing cruise there is altitude variations due to temperature and or wind gradients Above FL410, aircraft separation based on altitude must be avoid WAKE VORTEX FREE APPROACHES Corresponds to a "4D" LPV (4°5) approach with a runway threshold shift (up to 6000 ft) The pilot will monitor the preceding using the ASAS display : Will check aircraft separation
