Dr. Lewis “Bernie” Gratzer, the retired vice president of technology at Aviation Partners, passed away on Friday night. Gratzer, already a well respected aerodynamicist, joined Aviation Partners when the company was formed in 1991 to work on a blended winglet for the Gulfstream II. In 1994 he received patent #5,348,253 for his blended winglet design, the lynchpin technology of Aviation Partners’ winglet products.

While ATR and Bombardier continue to vacillate over plans to introduce a new 90-seat turboprop, Pratt & Whitney Canada keeps moving forward with an engine it believes will deliver a 20-percent fuel burn improvement over existing engines in the 5,000- to 7,000-shp range by the turn of the decade.

The Viking 400 Series Twin Otter will soon come equipped with a Safe Flight angle-of-attack (AoA) indicator as standard equipment. The TSO’d system consists of a lift transducer, computer and a speed indexer. The speed indexer provides the pilot heads-up guidance to approach AoA. The computer provides Arinc outputs to drive low airspeed awareness and AoA displays on the primary flight display. Safe Flight’s lift transducer is a heated leading edge sensor and is cleared for flights into known icing conditions.
