plane system

helix prop (H50F)

• made from carbon fiber

• PU-adhesive tape protects metal ends of prop

• Diameter: 65 inch, 2- blade

• fixed-pitch

pros of helix prop

high thrust, low noise, durability

Wooden prop (FPO2-80)

• fixed pitch

• diameter: 65 inch, 2 blade

• made of wood

• PU-adhesive tape protects metal ends of prop

BPRS

• ballistic parachute rescue system

• designed to save lives, but will destroy aircraft

  • use in absolute emergencies when landing isn’t an option

• 20 degrees nose-down attitude

• 2 belts aft of fuselage/wings

• touchdown feels like 12ft (3 meter) drop

BPRS max deployment speed

170 KTAS

Stall System (AOA indicator)

• given by AOA port on pitot tube

• on G3X, AOA meter shows up

• callouts: stallhorn, buffet, break

engine

• Rotax 912 UL engine

• 80 HP at 5800 RPM at straight and level

  • 5 min max time between 5500-5800 RPMs

• horizontally opposed

engine cylinders

• liquid cooled cylinder heads/air cooled cylinders

• 4 cylinder 4 stroke

  • 4 spark plugs per cylinder

carberetors

• dual float-type carberetors

• no carb heat needed

• dual bing carbs are more resistant to carb king

• intake air is pre-warmed/routed through engine bay

  • bing cards maintain consistent air pressure

  • intake routing provides passive heat

  • carb design minimizes pressure drop that leads to icing

• engine warms air surrounding carbs

oil system

• dry-sump

• contains 3.5L (3.7 Qts)

• advantages

  • prevents oil starvation during various attitudes and maneuvers

  • compact, beneficial for light sport

  • improves air cooling, reduces aeration

• cools, cleans, seals, lubricates

• oil type: aeroshell sport plus 4

fuel system

• 13.2 total/12.7 usable

• AVGAS or MOGAS

  • ours is 91UL non-ethanol

• level sensor in tank sends quantity to EMS display

• fuel breather system

  • vents tank

gascolator (sump)

filters out water and debris

• vapor lock

• when fuel changes from liquid to vapor in system

• causes: difficult engine start, power loss, engine failure during takeoff or climb

• MOGAS has a lower boiling point than AVGAS leading to a higher risk of vaporized fuel in fuel lines

• to avoid: limit ground time 1000 RPMs

Electrical system

• has a single generator, single battery, 14V DC system

  • at 5800 RPM it delivers 250W AC output

  • has RU912 rectifier for conversion

• Battery is 12V

  • if generator dies battery supplies 30 minutes of power

circuit breakers

if popped only reset once

auto-pilot

• GMC 507

• activated by 2 electronic servo motors for pitch 8 roll axis

how to activate and deactivate autopilot

• to activate

  • AP

  • choose nav, HDG, TRK

  • select altitude

• to deactivate

  • red button on left side

  • press AP

Landing Gear

• tricycle type landing gear

• nose wheel-steerable via rudders

  • strut is made of carbon fiber

• main wheels

  • have hydraulic breaks (red/brown fluid)

  • operated with hand break

tire pressures

• main: 40 psi

• nose: 26 psi
