  3. Fuel System overview
    • 172 lbs total
    • 166 lbs usable

    must have 13 gal per wing min to takeoff

    Interconnected tanks

    6 drain locations

    float type fuel quantity indicators
  4. Max Ramp Weight
    5524lbs

  8. Max Cylinder Head Temp (CHT)
    238°
  9. Max Oil Temp
    116 °
  10. Max Oil Pressure

    24°
  12. Min Oil Pressure
    10psi
  13. What is the starter limit?
    30 seconds in any 4 min
  14. Baggage Weights
    Main Cabin
    Aft Cabin
    Nose Campartment
    400

    120

    300
  15. Where is the Reference Datum?
    83.1'' forward of centerline through forward jack points
  16. Max Airspeed In Icing Conditions?
    130kts
  17. What conditions will the GearUp caution illuminate?
    • - Gear up with full flaps
    • - Gear up with Manifold Pressure below 13'' on both engines
  18. How do the Control Surfaces operate?
    Bearing supported and operated by push/pull rods and a conventional chain/cable system terminating in bell cranks.
  19. How do we control steering on the ground?
    Nose wheel steering - Spring loaded linkage from nose gear to rudder pedals
  20. What are the flap positions?
    • up - 0°
    • Apch - 15°
    • Down - 30 °
  21. What controls the prop RPM?
    Prop Governor
  22. How does the Synchronizer work?
    Matches RPM of engines to 25 RPM

    Magnetic pickup mounted in each prop gov sends electric pulse to a transistorized control box behind the pedestal

    Control box converts pulse rate into corrective commands that are sent to the approporite gov
  23. Fuel Crossfeed
    Normally each engine uses fuel from its respective fuel tank.

    If there is an engine failure fuel can be taken from either side

    Fuel can NOT be transferred between the two tanks
  24. Fuel Boost Pumps
    dual-speed, dual-pressure, electrically-driven, vane-type pumps

    Pumps Switch - HI, LOW, OFF
  25. When would you have the fuel boost pumps on LOW?
    minor vapor purging

    incrase fuel flow

    durring crossfeeding
  26. When would you have the fuel boost pumps on HI?
    Normal start, priming

    extreme vapor purging

    to provide fuel pressure for failure of engine-driven fuel pumps
  27. Electrical System:

    Tell me about the Batterys
    • (2) 25 amper-hour
    • 12 volt

    lead acid connected in series (in the floor of nose baggage area)
  28. Electrical System:

    Tell me about the alternators
    • (2) 100 amp
    • 28 volt
    • gear driven

    • alternator controll units
    • regulate volate
    • balance the load
    • provide overvoltage protection
  29. Electrical System:

    External Power
    Need 300 amps for starting

    • Batt - ON
    • Avionics - OFF
  30. Cabin Heating
    50,000 BTU combustion heater

    takes fuel form left tank (1gph)
  31. Instrument Air Pressure System supplies air to what systems?
    • Flight instruments
    • De-ice boots
    • Autopilot

    supplied by 2 engine driven, dry pressure pumps, interconnected forming one system
  32. Ice Protection:

    De-ice boots
    EDP pressure compresses air - through pressure regulators - to the distributor manifold

    Distributor valve decides to apply pressure or vacuum

    • AUTO - inflates for 12 seconds
    • Manual - inflates as long as switch is depressed

    Do not inflate in temps colder than -40
  33. Ice Protection:

    Windshield
    continuous in-flight use

    limit of 10 min on ground
  34. Ice protection:

    Propeller
    Electrical

    On-Off circut braker

    when the system is on the ammeter will show 14-18 amps
  35. Ice Protection:

    Other systems
    Pitot heat

    Stall warning (anti-ice)

    Heated fuel vents (underside of each wing outboard of nacelle

    • T-orque
    • S-piraling slipstream
  55. What are the 11 Vmc criteria used by the manufacturer?
    • Critical engine windmilling
    • Operating engine at takeoff power
    • Maximum takeoff gross weight
    • Bank ≤ 5° torward good engine
    • Adverse (aft) CG
