Weather

Welcome

We’re here to:

• Identify weather-related safety issues among our pilots

• Discuss how we, as instructors and examiners, can improve pilot training

• Help current and future pilots fly safely!

Aviation Weather Services, Advisory Circular 00-45G, Change 1 (July 2010)

Weather and Accidents

We’ll explore ways to address the most common scenarios, including:

• VFR into IMC• Flight into storms• Icing• Weather-related landing accidents

Practical Test Standards

Let’s look at the weather tasks in the Practical Test Standards, and discuss how we train these tasks.

• Private Pilot• Instrument Rating

The PTS

What should pilots know about “reading and analyzing” this weather chart?

Aviation Weather Services, Advisory Circular 00-45G, Change 1 (July 2010)

What about Area Forecasts?

Risk Assessment Matrix

Risk Assessment Matrix

VFR into IMC

The most common -- and most fatal -- type of weather accident.

• Of 14 such accidents in 2009, 12 were fatal *

• 86% fatality rate• Let’s explore ways to

address the pilot’s planning and decision-making for this scenario.

*2010 Nall Report of accidents in 2009: http://www.aopa.org/asf/publications/10nall.pdf

What training would prevent this?

• NTSB Identification: CEN11FA240• Baraboo WI, Cessna 150D• Student pilot and passenger – both fatal• Weather measured 10 miles from accident site:

– 700 overcast ceiling– 2 ½ miles visibility– Drizzle

• Additional question: Are there instructor and examiner responsibilities here?

What training would prevent this?

• CEN11FA247 Dickens, TX• Stinson 108• 3 fatalities• Closest observation

– Winds 060 at 9 knots– Visibility 5 miles– Mist– Overcast 500 feet– Temperature 39° F– Dew point 36° F

What training would prevent this?

• LAX00FA354 San Luis Obispo, CA on September 30, 2000 • PA38 night flight• One fatality, one serious injury• Sheriff's Deputy . . . reported that weather conditions

consisted of low clouds and fog with heavy drizzle . . .• A second deputy, who is a commercial certificated pilot,

estimated the overcast ceiling was at 300 feet and the visibility was near zero.

• According to the Federal Aviation Administration . . . The pilot did not receive a preflight weather briefing

Thunderstorms

Is it enough to teach pilots to stay at least 20 NM from a thunderstorm?

Aviation Weather Services, Advisory Circular 00-45G, Change 1 (July 2010)

Winds

Maximum cross-wind?Maximum gusts?Tailwinds?Wind shear?

How do pilots develop their own minimums?

Elaine Kauh, 2011

Icing

The Instrument PTS lists special emphasis areas including icing condition operational hazards, anti-icing and de-icing equipment, differences, and approved use and operations.

Is this enough?What about VFR pilots?

Aviation Weather Services, Advisory Circular 00-45G, Change 1 (July 2010)

Density Altitude

Personal Minimums

How do you teach and test for conditions that can vary greatly in different regions?

ADM and Weather

Hazardous attitudes• How do they relate to

weather-related accidents?

• Are you teaching and testing for safe decision-making?

Conclusion

• We can look at ways to use the PTS effectively

• Scenario-based instruction is another tool to teach weather-related safety
