Safety Affiliations

Agenda

 New Event Development process  New Events  Unstable Approach  FSF Unstable Approach Trial

Over 1100 Safety events and 4800 KPV’s It can be a daunting task to manage.

• Dr. Rumack; “Can you

fly this plane, and land it?” Ted Striker; “Surely you can't be serious.”

• Dr. Rumack; “I am

serious... and don't call me Shirley.”

Event Request



Tail Number: - Fleet: -  “Hi all, 

please you could an event be created to monitor pilot landing technique.

 Thank you.

Best regards,”

New Event Pro- Forma

The purpose of the new event pro-forma is to gather as much information as possible to help in the development of new events and expedite the development process.



Identify the hazard and the requirement for a new event.



Please provide sample data e.g. identify a flight(s) where an event should have triggered had an event been available.



Please provide a short Safety case for the development of this event



Please provide all applicable documentation or references supporting the requirement for this event: FCOM, AMM, SOP’S, CAA, EASA, ICAO.



Is the requirement for a new event the result of;



Special procedures for your operation



Company Safety Investigation/mitigating action (provide details)



Safety Study (provide study)



Safety Conference (specify)



Other (specify)



How would you expect the event to work using your available parameters?



Determine which parameters would be most suitable. (derived parameters may be created)



How necessary is this event to your operation? Choose one:



Critical



Urgent



Important



Desirable

Prioritisation, what do we do first?

New Event Prioritization

• Safety Benefit to the greater aviation community
• Customer completion of the New Event Pro-Forma in detail
• Regulatory requirements, as per; CAA, EASA, ICAO, FAA, TC etc.
• Company specific SOP requirements
• The length of time a request has been outstanding,
• The difficulty to develop the event as defined by the developers

(JIRA/Agile process)

• Promises made to a customer or expectations of the customer

New Events/ KPV’s 39 Events and 13 KPV’s

 XXX888 flight Control Pre-Flight

Check (except 787)

Touchdown to 60kts

 Events which could be used to

monitor non-precision and or visual approaches

 Speed Events Relative

Selected and Relative VLS

 LXX102 Unstable Approach

(excluding engine thrust)

 KPV’s for upset recovery

(UPRT).

 ATR icing events

Unstable Approach Event

FSF Study Unstable Approaches

 65% of all aviation accidents occur during approach and landing  3.5-4% of approaches are unstable  95-97% of unstable approaches continue to landing.  80% of ALA’s would be preventable if the crew decided to go-around

Unstable Approach Criteria

FDS IATA FSF Landing Gear Down Landing Gear down Landing Gear Down Landing Flap Set Landing Flap Set Landing flap Set Track is aligned to Runway (within 12 degrees or 30 if

• ffset approach

1. The aircraft is on the correct flight path 2. Only small changes in heading/pitch are required to maintain the correct flight path Airspeed

• Airspeed minus selected approach speed within -5 to

+15kts (for 3 secs)

• or Vapp within -5 to +15 kts (for 3 secs
• or Vref within -5 to +35kts (for 3 secs)

Target Approach Speed a few knots faster than the desired touchdown speed and on the “right” side of the total drag curve (corrected for wind if necessary)* The aircraft speed is not more than Vref+20 kts indicated airspeed and not less than Vref Glideslope deviation within 1 Dot* Stable aircraft in all 3 axes ILS glideslope deviation within 1 dot Localizer Deviation within 1 Dot* ILS Localizer deviation within 1 dot Vertical speed between -1100 and -200 fpm Rate of descent commensurate with the approach angle and approach speed (generally around 600-700 fpm for jet aircraft on a 3 degree approach) Sink rate is no greater than 1,000 fpm if an approach requires a sink rate greater than 1,000 fpm, a special briefing should be conducted Engine thrust greater than 40% N1 or (35% for A319/B787)

• r 10 secs or (1.02 for A319, A320, A321)

Engine thrust above idle Power setting is appropriate for the aircraft configuration and is not below the minimum power for approach as defined by the aircraft operating manual. If all of the above conditions are met, the approach is “Stable” *Note: ILS stability is not assessed below 200ft. The condition at 200ft (stable/unstable) *recognizing the aircraft is operating in a dynamic environment a tolerable range for each of these parameters (+5kts/-0kts airspeed for example), allowing pilots to make corrective inputs to maintain flight within the stabilized criteria. All briefing and checklists have been conducted. *An approach that becomes unstabilized below 1,000ft above airport elevation in IMC or below 500ft above airport elevation in VMC requires an immediate go- around

FDS Unstable Stats

 LXX100 current unstable event indicates about a 55% rate  LXX102 The New unstable event (which does not include power) is  6-7.5%
