Q

Définition dewpoint

A

A dewpoint can indicate water amount better than relative humidity.
Évaluer la quantité de vapeur d’eau contenue dans l’atmosphère. Point de rosée est la température, à une pression donnée, à laquelle doit être refroidis pour qu’il y ait saturation.

Q

You enter in a 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 a rigid altitude or airspeed and maintain present heading.

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