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-load limits than negative because the actual difference from 1g at rest is less significant for positive loads, and extreme negative G-loads are less likely to occur in flight.
Although not always a mandatory part of flight certification, specific spin training is highly recommended due to its critical role in recovering from unexpected stalls and spins.
Existing lightning safety protocols for ground personnel may be insufficient, as authoritative sources indicate lightning can strike up to 6-8 miles away from a storm, necessitating larger safe distances.
