Dr. Banners article in Julys issue, In-Flight Fires, mentions to bank 45 degrees during an emergency descent to create positive g loading and help offset negative g forces.Question: Generally speaking, why can airplanes withstand (or be certified for) greater positive g load limits than negative? Stated another way: Why are negative g loads more restrictive?Thanks for a great publication!
Airplanes are certified for greater positive g-loads than negative because the effective difference from 1g at rest is similar, and extreme negative g-loading is less frequently encountered in flight.
Although not mandatory for private pilot certification, spin training is valuable for pilots, even if it historically led to more accidents during training.
Existing lightning safety recommendations for ground personnel may be inadequate, as lightning can strike 6-8 miles or more from a storm, necessitating larger safe distances.
