JAPAN CONTINUES MASSIVE RENEWAL OF DOMESTIC ROTORCRAFT Amid geopolitical uncertainty and China’s claims to the Senkaku Islands, Japan continues the renewal of its fleet of military helicopters through both purchases from abroad and domestic procurement of some models. Since 2010, as territorial disputes have become heated, the number of interception flights conducted by Japanese military aircraft increased by almost three times, andDECODING WIND SHEAR
Pilots often equate wind shear in a preflight briefing with thunderstorms and severe turbulence. But one form of wind shear may occur when the air is glassy smooth — nonconvective low-level wind shear (LLWS). The forecast for this condition is probably the most misunderstood aviation forecast among pilots. In a terminal aerodromeforecast (TAF), it
AVX, L3 REVEAL DESIGN OF US ARMY FUTURE ATTACK HELICOPTER AVX Aircraft Company and L3 Technologies on April 15 unveiled a compound coaxial helicopter design with forward facing ducted fans and a side-by-side cockpit as the team’s pitch for the U.S. Army’s future attack helicopter.

DynCorp’s Global Eagle upgrade is proving the Huey’s ability to carry heavier weights at higher altitudes. THERE’S A LOT TO BE SAID FOR BRUTE FORCE. NO inching forward until you hit translational lift. No delicate control touch or PPT (perfect pilot technique). No praying you can get it airborne while ignoring the low-RPM warning horn. NOTAR: MORE THAN WHAT IT APPEARS TO BE This MD600, along with the MD520N and MD Explorer, utilize the NOTAR anti-torque system. Pilot inputs, however, are the same as those for a conventional tail rotor system.
