And Accident Study

By Bob Jackson,

MIC, ZSE CWSU

introduction 1
Introduction - 1
  • A well known ground school syllabus
    • allots 2 hours for weather theory.
    • Assumes pilots will improve their weather knowledge
  • Further weather study SHOULD BE mandatory for pilots.
introduction 2
Introduction - 2
  • Survey given to Certified Flight Instructors
    • CFI’s considered by some as the ‘Crème de la Crème of pilots’
    • Given in 1989
    • 238 responded
the survey 1
The Survey - 1
  • Survey consisted of five questions:
    • What license do you hold?
    • What is main source of additional weather knowledge since ground school?
    • Are you comfortable with present Weather knowledge?
the survey 2
The Survey - 2
  • Survey questions continued:
    • What is the average number of safety seminars attended per year?
    • If you could choose a weather topic for the next safety seminar, what would it be?

what wx topic do you want to see next
What Wx Topic Do You Want to See Next?
  • Basic Weather Principles
  • How to read Weather Charts
  • How to get the most from a Pilot Weather Briefing
  • In-flight weather recognition
  • Fronts, pressure systems
  • Icing and Turbulence
weather is a weak point to most ga pilots
Weather is a “Weak Point”to most GA Pilots
  • ‘Poor’ knowledge gained from ground school
  • Little/no additional training
  • In-flight is Not place to learn about weather!!

how much of aviation training is trial and error
How Much of Aviation Training is Trial and Error?
  • Take-offs ?

  • Aeronautics ?
  • Radio use ?
  • Aircraft instruments?
survey suggests
Survey Suggests
  • Proper emphasis NOT put on weather training.
  • Weather is Learned by “Trial and Error” !!!!
  • Not the way to learn about Weather!!
two ntsb studies of non fatal ga wx accidents
Two NTSB Studies of Non-Fatal(GA) Wx Accidents
  • Unfavorable cross winds major cause
two ntsb studies fatal ga wx accidents
Two NTSB studiesFatal (GA) Wx accidents
  • Lowering ceilings during flight
  • Lowering Visibilities during flight
  • i.e. Continued VFR flight into IFR conditions
  • “Violent Weather” was factor in a SMALL PERCENTAGE of fatal accidents.
ntsb recommendations
NTSB RECOMMENDATIONS
  • Visit FAA Flight Service Station
  • Visit NWS Forecast office
    • Make arrangements first
  • Familiarize with local terrain/weather patterns.

example vfr flight through the cascades
3,000 ft Elevation

Can not see pass in advance

Narrow, steep sides

No place to do 180 turn

Steep terrain makes up for low elevation

3,800 ft Elevation

Can see pass in advance

Wider with ‘sides’ further apart

Wide enough to do 180 turn

Example: VFR FlightThrough the Cascades

Snoqualmie Pass

Stampede Pass

Example of local ‘Rule of Thumbs’
  • No Rule of Thumb works all the time.
  • If you can not fly VFR through Stampede Pass...
    • You can not fly VFR through Snoqualmie Pass

Example of local ‘Rule of Thumbs’
  • If you can not fly VFR thru the gorge,
    • You can not fly VFR thru the passes.

WA Accident Causes
  • Dust/Haze -visibility restriction

discussion 1
Discussion - 1
  • Total of 191 fatalities
  • VFR to IFR - Most pilots were briefed about IFR weather in route.
  • IFR - Most used “improper IFR procedures.”
discussion 2
Discussion - 2
  • Many flying on “Invalid Briefings”(old)
  • Most had change to ‘back out’ but didn’t.
  • Many “Overconfidence of pilot”

Faithful/Fatal Decision
  • Sky - overcast
  • You realize that visibility is becoming restricted.
  • Ceiling and visibility gradually lowering.
  • Map shows high terrain in area.
  • You’ve flown in worse, so…
    • You press on.
faithful fatal decision1
Faithful/Fatal Decision
  • Flight could/should have waited.
  • Was that appointment so important?
  • When do you decide to do a 180?

summary 1
Summary - 1
  • Pilots don’t get good weather training
  • Weather is a “Weak Point” for most GA Pilots
  • Pilots need a good knowledge of basic weather
  • Pilots need knowledge of local terrain and it’s affects on flight.
summary 2
Summary - 2
  • Violent, easily recognized weather
    • is not main cause of aviation accidents
  • IFR weather conditions
    • main cause of aviation accidents
    • Recognition and Avoidance needs to be better taught to pilots
