Airbus interests in HUD

Intrinsic characteristics of the HUD

See through capability enablingthe aircrew to fly the aircraft usingcollimated flying symbols overlayingthe real world cues.

Potentiality offered by new HUD technologyWider field of view

LCD availability offering greater graphic capability/flexibility, and

easier video integration

HUD can be proposed as an option for allAirbus Fly-By-Wire aircraft

HUD and Airbus operational objectives

As a part of the Airbus continuous effort to enhance the flight

safety, HUD is considered as a tool toIncrease the pilot situational awareness.

Increase approach stability (NPA or VMC).

Increase landing accuracy

Enable seamless IMC/VMC transition.Provide a flexible platform for growth using new technologies

such as EVS, SVS and SGS to enhance surface operation andobstacle awareness.

HUD as a means to expand the operational capability of theaeroplane.Lower visibility take-off minima (75m instead of 125m)

Lower approach minima on some dedicated runways. (CAT IIapproach minimum on type I airfield)

HUD and Airbus Cockpit philosophy

HUD is an additional tool into a cockpit built around:

The Fly-By-Wire systems with its full set of protections.

The AFS with double channel FG, providing CAT 3B

capability.

The EFIS PFD/ND providing all the information required to

operate the A/C either in automatic or in manual flying.

The ECAM and FWS for A/C system monitoring.

HUD is not a substitute but a complement to theexisting avionics and need to be integrated.

HUD integration into the Airbus Cockpit

HUD will be fully integrated within this cockpit

Same control interfaces.

Same display logic and formats.

Same computation sources.

HUD cautions / warnings integration in ECAM.

HUD integration is one of the key factors toachieve the operational objectives with ahigh consistency and efficient use.

The other one being the HUD design rules

Airbus HUD design guidelines

Conformity with the external world

Key Display Elements must be conformal and overlay thereal world.

Trajectory based symbols must be preferred.

See through capabilityOnly need to show data must be displayed.

Declutter function, automatic/manual must be provided.

Symbol position and shape must be optimised.

Consistency with the existing avionicsFormat and mechanization of the data provided Head-Up

and Head Down must be consistent.

Same computation sources must be used.

Airbus HUD design guidelines (contd)

Intuitivity and ease of use

Potentially conflicting symbols must not be displayed.Analog presentation must be preferred to digital one.

All data required for given task within a flight phase must be

provided to prevent successive head-up/head down scanning.

The essential parameters used to control the aircraft in a givenphase must be located close to each other to improve the

scanning efficiency Integrity

IntegrityErroneous data must be clearly flagged.

Symbols reaching the limit of the FOV must be unambiguously

displayed.

HUD cautions and warning must be integrated in ECAM

HUD operational use

HUD will be mainly used during:

Take off roll and rotation.Rejected take off.

Initial climb out.

End of descent, initial and intermediate approaches.

Final approaches : precision, instrument and visual.Landing.

Landing roll, braking efficiency monitoring.

Go around.

HUD will be fully integrated in pilot training.The FFS syllabi will include the use of HUD from the 1st day.

Conclusion

HUD is proposed as a complementary equipment toexisting avionics to enhance the flight safety.

HUD will be fully integrated into the existing cockpit toensure high efficiency and efficient use.

Training will address HUD operation since day one.

HUD is designed to support future technologies that willenhance surface operation and obstacle awareness.

Airbus is getting involved in those technologies and will setnew standards to better respond to operational and safety

pilot needs.
