William (Bill) Hill the lead FAA Safety Team volunteer (Great Redding Area) will present a 90-minute program on the AIR around us.  Specifically how the AIR is modified depending on your PHYSICAL POSITION ON OR ABOVE the earth and how that AIR is further impacted by the TEMPERATURE and the HUMIDITY    (High-Hot-Humid)    Using my acronym:  BEP-W which stands for Brain, Engine, Propellor and Wing... I will discuss in detail the aspects that a pilot should consider as you act as a PIC.  It is all about performance, for you and your aircraft.
