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.

Introduction

The real Seneca II

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.

Development status/Issues/Todo

FDM (JSBSim):

  • poor single engine performance
  • no EGT indication - EGT is to low
  • supercharger code not realistic on low rpm
  • fuel source not switchable or cuttable

FDM (YASim)

  • not converging

Electrical system

  • Master switch no electrical function
  • Generator L/H and R/H produce the same output when on

Autopilot

  • Just interfacing the generic AP, Altimatic IIIC not implemented
  • LOC NORM and LOC REV not implemented
  • ILS not implemented

Avionics

  • GMA340: on some buttons, the first click after program start gets lost

General:

  • engine sound in cockpit does not differ from outside engine sound
  • animations of structural icing on wings, stabilizer, fin, etc.missing
