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.

Aircraft Performance Group has extended the functionality of its iPreFlight app for the iPad by integrating a flight planning module from Air Support. The revised app is available for preview in its Beta version at the APG booth (6423).

Previous versions of iPreFlight provided runway analysis and weight/balance calculations without the need for an Internet connection. Adding a module using the Air Support PPS flight planning tool allows iPreFlight to be used as a “one-stop” for pre-flight planning purposes.
