Seminole

• - 8 ply main (55 psi) - left main = squat switch - 3 green lts elongated, P-T-T - gear mute <25 deg flaps
• - 6 ply nose (50 psi) - right main = stall warn & mx hobbs - Emg Gear ext on panel <100kts - 6 to 7 secs to deploy
• - double puck brake - outboard stall = 0-10 deg flaps - 4 mast brake cylinders
• - 2 pistons per side - inboard stall = 25-40 deg flaps - 14" or 25 deg flaps gear warn horn - DAU
• - 4 pads per disk - barrel downlimit switches - gear unsafe annun panel
• - vented disk brake - nose uplimit deactivates heater vent blower - Day/night switch dims

A conductor whose resistance is known so that voltage drop will be proportional to the current flowing through it. Through Ohms law voltage or ammperage can be deduced.

• Failed closed solenoid
• Switch is closed before current is applied to circuit. RM opens when BM is turned on and current is applied. RM closes when turned on.

• 1) Turn off Alt Master
• 2) Over voltage relay
• 3) Alternator field coil breaker
• 4) Alternator belt breaks
• 5) Engine failure

• Forces
• 1) Centrifugal twisting force
• 2) Spring & N2 force (36-41 psi)
• 3) Aerodynamic twisting force
• Antifeather locks - prevent engine from feather on shutdown or below 800 RPM
• Unfeathering accumulator - 100 psi N2 / 290 psi oil

• Flight time - oil pressure on right engine
• Mx hobbs - right squat switch
• Heater hobbs - heater fuel pump

• * Low Bus Voltage - Tie Buss Voltage < 12.5 Vdc
• * Pitot Heat off/Inop
• Starter Engage
• * Alternator Inop
• * Oil Pressure
• Gear Warning - gear neither full up or down
• Heater overheat - 300 deg F
• * - on prior to engine start

• 2 Engines
• Lycoming
• O-360-A1H6
• LO-360-A1H6
• 180 HP @ 2700 RPM
• Four cylinder, direct drive, horizontally opposed, air cooled.

• 1) Monitor - voltage tie bus, 14 Vdc
• 2) Regulate - com with other VR to balance system load
• 3) Protect - Pulls Alt off line if current > 17 Vdc
