This is a model of a Piper PA34-200T Seneneca II. The Seneca has been made by Piper since the early 1970's and some 4500 were made since then. It has six seats in a pretty large cabin, two turbocharged counterrotating engines producing 200hp up to 12,000 ft. It cruises at 170ktas in 12,000ft at 65% power. Certification for flights into known icing conditions and the nice single engine behaviour made the Seneca a popular multi engine trainer.

Almost all controls, switches, gauges and indicators are implemented and functional in the cockpit. For description of the panel have a look at the [[Seneca II Panel Reference]].

Since the Seneca provides anti- and deice equipment, I tried to model structural icing into flightgear. A little nasal script does most of the work: First it reads the property nodes under /sim/model/icing where any number of iceable elements configure the ice sensitive elements of the aircraft. Each element have a name, a sensitivity to icing, may have a salvage control and the name of a output property where the collected amount of ice is written to. After the initial configuration, a timed loop is executed every 2 seconds. It

Maneuvering speed decreases at lighter weight as the effects of aerodynamic forces become more pronounced. Linear interpolation may be used for imtermediate gross weights. maneuvering speed should not be exceeded while operating in rough air.
