LOSA Rationale Proactive snapshot of system /
crew performance strengths and weaknesses in
normal operations (just like a health checkup)
9
LOSA Measurement Challenge
  • Challenge - What type of observational measure
    best captures safety performance data in normal
    operations?
  • Concerns
  • Observer overload Cant capture everything
  • Data analyst overload Must have a roadmap for
    interpretation
  • Manager overload Data need face value and point
    to safety issues
  • Solution Threat and Error Management (TEM)

10
Primary LOSA Measures TEM
  • What do flight crews do to safely fly from A to B?

Wheres CRM and human factors? Non-technical
skills are one of many contributors to
effective/ineffective TEM performance
11
LOSA Deliverables Diagnostic Findings
  • Most frequent and mismanaged threats
  • Most frequent and mismanaged errors
  • Fleet and operational differences
  • Comparison to other airlines on LOSA safety
    indices

12
Sample LOSA Analysis
13
Raw Data Narratives
LOSA Flight 23 Error 1 A340 ARPT 401 to
ARPT 204 (Crew 8) Phase of Flight
Takeoff/Climb Pilot Flying CA Takeoff / Climb
Narrative Almost immediately after takeoff, the
Captain started a turn up the river, and did not
wait until 400 feet, per SOP. About 300 feet,
captain reached over to MCP (called FCU on
Airbus) and selected Flight Path Angle. He did
not tell FO of this selection, which is very
unusual of a setting. In fact, the FO later asked
me if I had ever seen anyone use this selection
and stated that he has never seen it in his 2
years of being on the Airbus. Because the Captain
did not tell the F/O what he was doing, when the
FO noticed this setting, he reselected the more
common mode (Heading). Captain then reached over
and then reselected Flight Path Angle. This led
to a brief discussion of whether of not the
aircraft would capture NAV in this setting. As a
result of all of this, the FO missed ATC handoff
to departure control, a call that was not made
until the aircraft leveled off at 5000 feet. Both
Captain and FO were involved in heads-down stuff
as the aircraft leveled off. If the autopilot
would not have leveled off, then the crew would
have not caught it, because they were doing
extraneous things. (FO, programming MCDU
Captain, looking at weather).

Raw Data Threats
LOSA Flight 50 Threat 2 B737-700 AUS /
DFW Threat Description Threat runway switch. We
had expected and had briefed 17Left from the ATIS
broadcast. No reason for the switch given by
ATC. Threat Management Description Scramble to
brief new runway plus linked to error of not
finding the proper approach chart and automation
error of not setting up computer for the landing
runway. FO left the approach and arrival route
for 17Left in the FMC instead of the new runway.
Based on this the aircraft reached DIETZ and
started a turn to heading 350 which was still the
active route instead of the 300 heading
assigned. Phase of Flight Des/App/Land Threat
Type ATC Threat Code ATC runway change Threat
Outcome Linked to Flight Crew Error

Summary - LOSA
  • Primary features
  • Purely diagnostic no solutions flight
    operations health check
  • Captures system safety and pilot performance
    strengths and weaknesses in normal operations
    using observations
  • Analysis
  • Aggregated TEM data provides a safety snapshot of
    flight operations on a typical day
  • Organizational change
  • Measure the effectiveness safety solutions with a
    follow-up LOSA

16
LOSA Case Study One
  • Two LOSAs (3 years apart)
  • 1st LOSA results An example of targets
    identified
  • Undesired number of below standard leadership
    ratings
  • Problems associated with checklist protocol /
    usage
  • High number of unstable approaches
  • Low rate of error trapping (errors detected and
    managed)

17
LOSA Case Study One
  • Airline response to data
  • Formed committees to address targets for
    enhancement
  • Implemented a leadership training module in
    recurrent
  • Revised checklist philosophy
  • Established bottom lines for unstable approaches
  • Implemented error management training course for
    all pilots
  • Check airmen were trained in evaluating error
    management

18
LOSA Case Study One
  • 2nd LOSA results
  • Captain leadership scores significantly improved
  • 40 reduction in checklist errors
  • 77 reduction in unstable approaches below 1000
    ft.
  • FOQA (QAR) showed similar trends
  • Two fold increase in error trapping rates
  • Change in the check culture to evaluate error
    management
  • Increase management buy-in on the safety change
    process

19
LOSA Case Study Two
  • 1st LOSA results - Targets identified
  • Improve energy management issues during
    descent/approach/land
  • 18 of flights with a speed deviation undesired
    aircraft state
  • Lower the prevalence of unstable approaches
  • 11 of flights with an unstable approach
  • Lower prevalence of checklist errors
  • 50 of flights with a checklist error
  • Improve monitor/cross-checking performance
  • 38 of errors went undetected (not responded to
    by the flight crew)
  • Improve ATC threat management
  • 22 of ATC threats were mismanaged - linked to
    flight crew error

20
LOSA Case Study Two
Proactive safety change . Over one year, approx
182,500 flights, 4 rate 7,300 unstable much
better than 11 rate 20,075 unstable
21
Convergent Validity LOSA and ASAP
Well, James, very nice information. We see a
lot of the same things in our ASAP database
(voluntary incident reporting)
- Quote from an ASAP
Project manager
  • Why would an airline do a LOSA when ASAP
    (incident reporting) captures the same things?
  • ASAP collected when an event occurs
  • LOSA collected independent of event
  • By focusing on LOSA data implementing effective
    solutions, airlines can should be able to lower
    their potential for incidents / accidents

22
LOSA Operating Characteristics
23
Secret to LOSA Success
LOSA is not for all airlines - Its success
depends on pilot trust
Regulator
Check Airman
Nobody
Low pilot trust Low quality data because
there will be no differentiation between LOSA and
proficiency checks by regulators and check airmen
24
LOSA How to Gain Pilot Trust
LOSA is defined by 10 operating characteristics
  • Jumpseat observations during normal operations
  • Anonymous, confidential, and non-punitive data
    collection
  • Voluntary crew participation
  • Trusted and trained observers
  • Joint management / union sponsorship
  • Systematic observation instrument
  • Secure data collection repository
  • Data verification roundtables
  • Data-derived targets for enhancement
  • Feedback of results to line pilots

25
LOSA Operating Characteristics
  • Jumpseat observations during normal operations
  • Routine flights only
  • No line checks or training flights
  • Anonymous, confidential, and non-punitive data
    collection
  • No names, flight numbers, or other identifying
    information
  • Observer identity kept anonymous
  • Data only used for safety purposes no
    disciplinary action
  • Voluntary crew participation
  • Flight crews have the right to decline a LOSA
    observation
  • Typical denial rate is very low 1 per 100
    flights

26
LOSA Operating Characteristics
  • Trusted and trained observers
  • Trust
  • Selection process management / union list of
    candidates
  • Mostly regular pilots - Captains and First
    Officers
  • Training
  • Five days ground school (2), test observations
    (2) recalibration (1)
  • Curriculum
  • LOSA protocol
  • How to write quality narratives
  • TEM recognition, recording and coding

27
LOSA Operating Characteristics
  • Joint management / union sponsorship
  • Steering committee Flight Ops, Training, Safety
    and Union
  • Symbolized with a signed agreement and sent to
    all pilots
  • Systematic observation instrument TEM based
  • Observers only record the TEM events they see
    no judgments
  • Secure data collection repository
  • Third party or pilot association gate keeper
  • Pilots must believe that observations will not be
    misplaced

28
LOSA Operating Characteristics
  • Data verification roundtables
  • TEM data checked for coding accuracy and
    consistency with SOP
  • On completion, data analysis begins
  • Data-derived targets for enhancement
  • Serve as benchmarks for organizational change
  • Measure, change, measure again approach
  • Feedback of results to line pilots
  • Results and information on how airline management
    intends to respond with organizational change

29
LOSA Defined
  • To ensure standardization, LOSA must have all ten
    operating characteristics
  • If less than ten, the project needs another
    acronym
  • Endorsed by
  • ICAO
  • FAA (pending advisory circular)
  • IATA
  • UT
  • TLC
  • IFALPA
  • US ALPA

Frequently Asked Questions
31
LOSA Cost?
  • Depends on a number of factors indirect and
    direct costs
  • Number of observations to be collected
  • Number of external and internal observers
  • Depth of data analysis
  • Insurance discounts?
  • External provider fee LOSA Collaborative and
    others
  • Some examples of misleading efforts to lower
    costs
  • Observations only no roundtables or data
    analysis
  • Operating crew as their own observers / self
    report
  • Video in the cockpit / analyzed by one retired
    pilot in the airline
  • These projects MIGHT have value but they are not
    LOSA

32
Length and Size of LOSA?
  • Project Length
  • Average 8 months from planning to a final report
  • Airline 75 of time spent on planning
  • LOSA Collaborative
  • 30 of time spent on planning, observer training,
    data collection
  • 70 spent on data verification, analysis and
    final report
  • Project Size Want to extrapolate to everyday
    operations
  • Weighted sample to match daily departure rates
    per fleet
  • Minimum number of observations per fleet 40
    observations
  • Cap observers to no more than 15 observations to
    prevent observer fatigue

33
Continuous or Snapshot LOSA?
  • Recommended Snapshot approach with a sample of
    observations
  • Continuous LOSA more cost, questionable value
    over snapshot LOSA
  • A snapshot approach is more manageable
  • There is a start and end for data collection that
    marks a point in time to derive targets and get
    to the real work of making changes
  • Snapshots can complement other continuous safety
    efforts such as QAR or incident reporting

34
How Realistic is LOSA Data?
  • Doesnt observers change the way flight crews
    behave?
  • If they do, then LOSA results are
    underestimates of what actually occurs in
    normal operations
  • If pilots fake good in front an observer,
    explain.
  • Average three errors per flight 25 are
    mismanaged
  • Average 32 of flights have an undesired aircraft
    state
  • Common to observe substandard CRM or procedural
    violations
  • Pilots calling girlfriends during taxi-out
  • Offering cigarettes to LOSA observers in the
    cockpit

35
What about observer bias?
  • Major sources of observer bias
  • Sensitivity Observers are more sensitive to
    certain areas of flight operations (ex, human
    factor experts that only see human factor
    problems)
  • Proficiency - Lack of TEM knowledge to correctly
    collect data
  • Fatigue Observer burnout less data collected
    less precise
  • Some data quality controls
  • Use many different observers (Captains, First
    Officers, instructors, external)
  • Cap the number of observations per observer
  • Focus observers on gathering just the facts
    no judgment of causes
  • Test for TEM knowledge during training backed up
    with data verification

36
Biggest Threats to LOSA Success?
  • LOSA mutations and people calling or thinking its
    LOSA
  • Senior management not briefed and/or prepared for
    the possibility of undesirable results
  • Results not communicated to pilots affects
    pilot acceptance for the second LOSA
  • Unmotivated observers
  • No safety change process in place to act on LOSA
    findings
