GBAS

• SATELLITE BASED GLS EQUIVALENT OF ILS WITH SINGLE GROUND FACILITY AT

EACH AIRPORT

• GBAS, AN ICAO TERM, IS LOCAL AREA AUGMENTATION.

• AIR CARRIERS PARTIALLY EQUIPPED OR PROVISIONED

• 24 GAST-C LOCATIONS WW (US HAS EWR, HOU & 2 BOEING

FACILITIES)

• FUTURE GAST-D EQUIVALENT TO ILS CAT III

10

GPS BASED AUGMENTATION SYSTEMS

EFVS

• USES ‘OPAQUE SCENE’ BUSTING TECHNOLOGY

• INFRARED, MULTI-SPECTRAL CAMERAS AND MILLIMETER WAVE

• MUST USE HEAD UP DISPLAY (HUD) FOR CREDIT

• FUTURE DUAL HUDS BUT MAY BE WEARABLE

• CAN BE COMBINED VISION INCLUDING USE OF SYNTHETIC VISION

• MUST INCLUDE CRITICAL FLIGHT FUNCTIONS ON HUD

SURFACE MOVEMENT GUIDANCE CONTROL

ISSUES 1

• GPS VULNERABILITY

• UNINTENTIONAL AND DELIBERATE INTERFERENCE

• BACK UP REQUIRED SUCH AS DME

• INFRASTRUCTURE & AIRCRAFT EQUIPAGE

• FUNDING, OPERATOR COST, PRICES MUST COME DOWN

• ABILITY TO USE NEW TECHNOLOGIES & PROCEDURES

• IF EQUIPPED AND ALLOWED, CONTROLLERS TO ENABLE

20

SAFETY IS ASSUMED AS THE NUMBER ONE CONCERN NOW AND GOING FORWARD

ISSUES 2

• EFVS PREDICTABILITY

• NEW TECHNOLOGY AND ‘BLENDING’ WILL RELIABLY SEE THE REQUIRED VISUAL CUES

• HARMONIZATION

• BEING ABLE TO USE ELVO WORLD WIDE UNDER THE SAME RULES & GUIDANCE

SAFETY IS ASSUMED AS THE NUMBER ONE CONCERN NOW AND GOING FORWARD
