The North Atlantic Warming Hole (NAWH) is linked to a slowdown of the large system of ocean currents that carry warm water from the tropics northward into the North Atlantic.

Turbulence reports must be carefully evaluated because one citing moderate turbulence encountered by a Boeing 757 would translate into a much worse experience in a King Air. Why? In general, business aircraft are lighter and have lower wing loading than a commercial jet, and many have relatively little wing sweep, all of which increase the gust load factor and thus the amount of turbulence felt.

A look at the symbology on aviation weather charts.

Prudence suggests that flight plans of the future more closely look at the likelihood of encountering clear air turbulence.

Passengers may be in for bumpier rides in the future and the potential for serious injuries when unbuckled passengers and flight attendants are jolted around the cabin.

Faster, higher, roomier, quieter and, surprisingly, less expensive are five ways to differentiate the $60 million 6,500-nm-range G600 from the G550 in Gulfstream’s top-end product line-up.

These graphs are designed to illustrate the performance of the Gulfstream G600 under a variety of range, payload, speed and density altitude conditions.
