Important Limitations - POH Section 2 • Maneuvering Speed 2800# - 113 KIAS, 2400# - 105 KIAS (note major changes for weight) • Flap Extension Speeds , Vfe 10 degrees 130 KIAS 10-30 degrees 95 KIAS • Landing Gear Operating/Extension Speeds, Vle 125 KIAS • Maximum Vent Window Open Speed 105 KIAS • Never Exceed Speed 174 KIAS • Power Plant yellow arc 1400 to 1750 below 10 inches manifold • Weight Limit 2800#, Center of Gravity shift with gear retraction +2776 #-inches • Normal Category Only +3.8 -1.52 no flap • NO SPINS • Fuel Selector must be on BOTH for Landing • Placards also shown in POH
Aircraft Systems and Descriptions POH Section 7
Airframe • Cantilever Wing structure • Wet Wing Tanks • Stabilator Tail • Smooth Flaps and Ailerons • Slots in Stabilator Tail to reduce stall speed of Stabilator
Ground Control • Best to use the Tow Bar for all ground Handling • NEVER PUSH On Stabilator • Turn limits on tow bar 39 degrees right and left • If necessary, push on main gear legs • Minimum Turning radius using differential braking, approximately 31 feet
Operation of Flaps • Pre-Select Flap Control • Detents for 10 degrees and 20 degrees • Must move Flap Lever slightly right to pass 10 and 20 degree detents • One finger can move flaps up after short field landing if maximum effort required
Landing Gear System • Gear and Downlocks Hydraulically Actuated (5606 hydraulic fluid, red) • Two Cylinders, one for both mains, one for nose gear • Hydraulic Pressure comes from hydraulic power pack behind baggage compartment bulkhead
Landing Gear System (2) • Landing Gear System Hydraulic Pressure serves to hold gear up, no up locks on main gear • Power pack Operation controlled by pressure switch, 1500psi off, 1000psi on • Landing gear Lever directs hydraulic pressure • Lever must be pulled out slightly to change position, requires two fingers • Position Indicator Lights for UP and DOWN • If a bulb burns out, use other indicator, be very cautious if changing bulb in flight! • Landing Gear Retraction or Extension takes just under 15 seconds
Landing Gear System (3) • Safety Switch to prevent landing gear retraction on the Ground on nose gear disables any operation of the hydraulic pump • Emergency Hand Pump provided in case of Electrical Pump Failure to Extend Gear • Landing Gear does have Aural Warning unit that provides an intermittent tone thru the cabin speaker if the throttle is below 12 inches manifold pressure • If all Hydraulic Fluid is lost, there is no way to extend the Landing Gear
Cabin Doors • Doors are operated by a three position handle OPEN, CLOSE, LOCK • Door Opening in Flight is not Serious and there is no need to Land • Doors can be Closed in Flight with Procedure in POH • DOORS ARE VERY LARGE and OPENING DOWNWIND CAN CAUSE HEAVY STRUCTURAL DAMAGE!
Engine and Engine Instruments • 4 Cylinder 200HP Fuel Injected Lycoming with belt drive alternator dual magneto and prop governor • Throttle and Friction knob • Vernier Mixture Control • CHT Gauge, ideally kept below 380 degrees f by use of Cowl Flaps • Manifold Pressure Gauge, Normal range 15 to 25 inchs • Fuel Flow / Fuel Pressure Gauge Normal range 6 to 13 GPH, 19 GPH redline
Engine and Engine Instruments (2) • EGT gauge used for leaning • Engine oil, maintain 6 quarts minimum • Automatic Alternate Air Door will open if needed 5% loss of power • Cowl Flap Control to adjust engine cooling by trailing a lower cowling edge open
Propeller • Constant Speed with Prop Governor to maintain speed • Governor is a pump which boosts the engine oil to higher pressure • Governor also is set by prop control for a speed and senses engine speed to adjust oil pressure that is sent to the prop to adjust blade angle • Oil pressure on the piston in the propeller hub twists the blades to higher pitch (lower rpm) • Centrifugal force on counterweights plus an internal spring returns the pitch to low when oil pressure is removed from the piston • If power is insufficient to maintain set RPM, then RPM will drop • Special WARNING about Prop Governor Service
Fuel System (2) • Two Integral fuel tanks formed by sealing off part of the wing • Two Fuel Reservoir Tanks (Header Tanks) with integral drains connected to lever on floor • Fuel Valve has Left, Right, Both and Off • Electric Auxiliary Pump used mostly for Priming • Fuel Servo hooks to throttle and mixture control and senses mass air flow • Fuel Servo sends a specific fuel pressure to the diverter manifold which distributes to each injector and to the Fuel Pressure gauge calibrated for Fuel Flow • Vent lines for Fuel Tanks on opposite wing • Line of holes in filler neck allows easy fueling to 22 gallons each side for larger loads • Fuel Selector must be in BOTH position for Takeoff and Landing • Use the Auxiliary Electric Fuel Pump in the event of engine driven pump failure
Hydraulic System (2) • Electrical Hydraulic Pump • Separate 30 amp Circuit Breaker Push/Pull type • Pump turned on by Pressure Switch • Proper Application of Pressure direction selected by the Gear Selector Handle, a simple valve • When the gear reaches an end point, up or down, the Reed Switches close to illuminate the bulb either up or down • CAUTION, shorting the bulb socket will damage the Reed Switches Permanently if power applied
Hydraulic System (3) • Emergency Hand pump Functions to pump gear down, located between the front seats • Normal Operation time is 12 to 13 seconds for extension or retraction
Electrical System • 14 Volt • 60 Amp Alternator • Split Buss Contactor to Separate Electronics Bus, Also hooks to Avionics Master • Split Master Switch • Ammeter indicates Charging Rate of Battery Only • Over Voltage Warning Light will illuminate if the Field Current is Removed • Turn Master Switch Off and Back on to Reset • Ground Service Plug – Cannot be used to run Radios on the Ground • Can be used to Charge a Dead Battery if Master is turned on after Connection
Vacuum System and Instruments • Dry Vacuum pump – Can fail suddenly • AI and HI both Vacuum Driven • Normal Suction 4.6 to 5.4 inches Mercury
Vacuum System and Instruments (2) • N34208 Equipped with SVS Backup Vacuum System and Warning Light • Vacuum from engine Manifold riser is used to provide Suction in the event of Pump Failure • Must NOT have throttle full in to work, need to reduce Manifold Pressure according to Placard, approximately 2 inches
Vacuum System and Instruments (3) • To activate Pull Handle
Autopilot • Wing leveler • Heading Hold • Nav Trak • Uses Heading Indicator and Turn Coordinator as Feedback
Key Speeds • 62 KIAS - Short Field T.O. speed at 50 feet with 10 degrees flap • 82 KIAS - Vy best rate SL. • 90 – 100 KIAS Normal Climb • 63 KIAS Short Field Approach with 30 Degrees Flap (plus allowance for gust) • Maximum Demonstrated Crosswind 16 Knots
Normal Operations (2) • Starting Engine Cold and Hot, Dangers of Fire • Power Check • Wing Flap Settings • Retraction of Gear After Takeoff • Crosswind T.O. • Enroute Climb and normal power, fuel flow and speeds, engine temperatures, cowl flaps • Cruise, setup, leaning, power setting, cowl flaps • Descents MP, cooling • Before Landing CGUMP • Final • Fence Check • Go Around
