This is a model of a Piper PA34-200T Seneneca II. The Seneca is 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 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
/instrumentation/adf/model
to
ki228
in the property browser or use the command line switch
--prop://instrumentation/adf/model=ki228
when starting up the Seneca
 
=== Tutorials ===
Using the menu items ''Help->Start Tutorial'' a bunch of tutorials are reachable.
* '''Cold Start''' Puts your aircraft into hibernation mode. Everything is off.
* '''Hot Start''' Everything is ready to go, just start the engines and fly.
* * '''Check''' These are the checklists from [[Seneca II Checklist]]


=== Structural Icing ===
=== Structural Icing ===
[[File:SenecaII_icing.jpg|thumb|250px|Icing on the temperature probe]]
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

When oat is above zero degc, Ice melts at a rate of 0.5" per 10NM at 10degc, the warmer the faster.

=== Pitot Icing ===
The pitot tube is prone to icing, too. A little agent is waiting for you to get into icing conditions without switching on the pitot heat. If he gets you, he will fail your pitot system which will result in some strange airspeed indicator behaviour.

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.
