Divergent Vs. Convergent Signatures• Big picture easier to see from the air

Time Consuming • Ground surveys are inefficient

Length/Width/Start/End• Fine details are harder to determine from ground

Embedded Signatures• Tornadic signatures embedded in overall straight

line wind damage – common in Ohio Valley QLCS storms

Multi-disciplined team approach for a more comprehensive survey

Better Surveys!

The Civil Air Patrol is a GREAT resource…

However…

Not always feasible due to budget constraints and timeliness issues.

AOPA Online’s Dan Nimowitz wrote an article about the program and our first volunteers

Pilots must clearly understand this is a volunteer program

Pilots cannot be asked to fly,they must already be planning

to fly that day

Pilots cannot becompensated

Be sure the pilot has a specific path with recognizable landmarks to follow.

Example…cities, rivers, lakes, airports, etc.

Don’t send them on a “Wild Goose Chase”.
