Flight Safety and Operational Benefits
Data
 Only approx. 2% of all landings with Autoland
 During > 97% of all approaches no Safety Benefits with Autoland
 Autoland Systems limited for straight and standard ILS/MLS Approaches
 Autoland not capable for PBN/RNP Approaches, (design & certification)
 HUD Safety Benefits during 100% of all flights from Takeoff until Landing

Cat IIIa Autoland only used
in approach and for landing
HGS can be used in all phases of flight

Flight Safety and Operational Benefits
4 HGS Proficiency Levels
 Level 1 : Initial Introduction
Tunnelling, Fixation, Adaptation
(can be reduced using FTD)
 Level 2 : Secondary Awareness
Prioritizing the information acquisition (FFS Phase)
 Level 3 : A World beyond the combiner
Integration HGS into conformal world and combining other cockpit information
 Level 4 : The HUD as another flight Deck Tool /
HGS as the Primary Flight Display Reference
Final Stage of proficiency, symbology becomes second nature
Pilot becomes more aware of air mass effect and performance (Aircraft)

Analysis Results
Conclusions of Report September 2009
 HGS would have likely or highly likely prevented the following
percentage of a accidents
– 38% of all the accidents/incidents
• 69% of Takeoff and Landing Accidents
• 57% of Loss-of-Control Accidents
• 33% of Miscellaneous Accidents
• 19% of Propulsion Accidents
• 3% of Undercarriage related accidents
 The most influential individual HGS safety properties were:
– Flight Path Vector
– Flight Path Acceleration
– Speed Error Tape

Analysis Results
Why are dual HUDs standard on the B 787 Dreamliner ?
•

Principal argument: “Standard equipment
dual HUDs will save at least one aircraft
over the life of the program”
•

90% of customers wanted dual HUDs but
Boeing assumed only 10 to 20% would
select the option
–
–
Limited “hard” payback on autoland
equipped aircraft
Most airlines have difficulty quantifying
safety benefit

HGS Operation
Operating Philosophy
 HGS will be used during all phases of flight
 All Approaches will use the same SOPs.
 Flight Path - Energy Flying
Pitch - Power
 Use of an appropriate Level of Automation is a Standard Procedure
 Manual Flying while using Autothrottle
 Practicing Manual Flying Skills is encouraged
( Pilots to keep proficient with basic flying skills)
 First Officers qualified to conduct CAT III Approaches
