This is a model of a Piper PA34-200T | This is a model of a '''Piper PA34-200T Seneca 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. | ||
The model was built using the Pilots Operating Handbook, a real Seneca (D-GEJL) and some flight performance data derived in real flights. | The model was built using the Pilots Operating Handbook, a real Seneca (D-GEJL) and some flight performance data derived in real flights. | ||

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]]. | |||
The default KI227 ADF indicator can be exchanged into a KI228 RMI indicator coupled to ADF and NAV1 radio. | |||
To use the KI228, simply set the property | |||

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 | Since the Seneca provides anti- and deice equipment, I tried to model structural icing into flightgear.
