1
Q

Définition dewpoint

A

A dewpoint can indicate water amount, better than relative humidity.

Q

You enter in thunderstorm, what to do?

A

If can not escape, keep altitude and adjust proper throttle. Don’t turn back. Slow to turbulence penetration speed. Do not attempt to maintain rigid altitude or airspeed. Maintain present heading.

Don’t choose “maintain altitude, reduce to Va”
