Pilot Report: The PT6A Powered Piaggio Avanti Evo

The P.180 Avanti Evo has a “wow” factor that is not present with many other twin turboprops of a similar size. Yes, it does have three lifting surfaces, a T-tail and two pusher propellers but it’s how they are put together that is the important thing. The forward wing (not to be called a canard, as it has no moving flight controls other than forward flaps) is positioned on the underside of a gracefully sweeping nose and is home to two pitot tubes underneath and, unusually in Western types, has a significant anhedral.

Trip Report: PT6A-34 Powered Quest Kodiak Series II

Driving on an early May morning to Sandpoint, Idaho, to see the Quest Aircraft factory and then fly a new Kodiak 100 Series II to California, it was clear that icing conditions were not only forecast but likely in the wet gray clouds that shrouded the local mountains. For the flight-into-known-icing-certified Kodiak, however, icing is not a problem, and in the 11 years since it entered service, the capable utility single-engine turboprop has proven its mettle in challenging flying all over the world.

The PT6A-50 Powered De Havilland Canada DASH-7

During the 1950s and 1960s, the aircraft manufacturer De Havilland Canada (DHC) acquired extensive experience in the construction of small and medium capacity transports with short takeoff & landing (STOL) capabilities, such as the “Otter”, “Twin Otter”, “Caribou”, and “Buffalo”. In the early 1970s, DHC decided to create a four-engine turboprop medium STOL airliner, which emerged as the “DHC-7” AKA “DASH-7”. The DASH-7 was only built in modest numbers, though it did prove useful as a military surveillance platform. DHC followed it with a twin-turboprop airliner, the “DHC-8” AKA “DASH-8”, which proved much more successful. This document provides a history and description of the DASH-7 and DASH-8.
