Q

What is required for a thunderstorm to form and what operational hazards are present

A

Formation requires unstable air, lifting motion and high humidity

Avoid thunderstorms by flying at least 20 miles away, stay out from undeer the anvil top to avoid hail, be aware of possible microbursts, when penetrated ask ATC to vector you around larger cells, do not set autopilot on alititude, turn up cockpit lighting to reduce blinding effects of flashes, when on an approach and you experience a sudden increase in IAS expect a decrease in IAS to follow
