Describe engine
Rotax 912ULS with dual ignitions and Bing altitude compensating carburetors. 100HP.
What is the minimum oil temp for engine run-up?
120 degrees
What is the normal voltage output of the generator?
12-15
What would indicate the generator has failed?
Steady discharge on ammeter and voltage indication under 12 volts.
Talk about the spar pin unsafe override switch.
If a fault occurs in the spar pin indication system and an in-flight engine restart is necessary, this switch will override the disabling of the starter.
Engine fire during start
If confined to intake or exhaust system (engine flooding) -
Continue cranking engine with starter
Choke - push open
Throttle - full open
Inspect aircraft for damage and cause prior to restart
Engine fire during flight
Fuel off Ignition switches off Expedited descent and land immediately Radio Master off Airspeed down to 60 (55 minimum) on final Flaps down after landing assured Open canopy Touchdown with minimum airspeed
Electrical fire
All electrical switches off (leave ignitions on)
Air vent open if needed
Use extinguisher, if available
Land immediately
Generator/Electrical Failure
Failure:
Turn off all non-essential electrical equip to conserve battery power - including avionics. EFIS & GPS will continue on internal batteries for a LIMITED time.
Land asap
Runaway Generator:
Pull 30A main bus fuse immediately
Turn off all non-essential elec equip to conserve battery power - including avionics. EFIS & GPS will continue on internal batteries for a LIMITED time.
Land asap
Engine failure on take-off
Immediately & aggressively move control stick forward to prevent loss of airspeed. Airspeed 60 (55 min) If airborne w/sufficient runway - throttle close and max breaking after touchdown. If airborne w/insufficient runway - attempt engine restart if altitude permits: Check fuel on Choke - check open/push Ignition switches both on Fuel pump - check fuse If restart is impossible: Select best landing option Flaps full down Fuel shut-off valve - off Ignition switches - off Master off Touchdown w/min airspeed
Engine air restart
Maintain airspeed - 60 (55 min)
Ignitions both on
Fuel pump - check fuse
Fuel on
Choke open
If restart not possible: change throttle and/or choke settings in attempt to restart
Follow “forced landing procedure” if unable to restart
Precautionary Landing Approach
When power is still available but complete power failure is considered imminent.
Normal procedures (higher & closer pattern than normal)
Airspeed - 60 (55 min)
Throttle - closed when in gliding distance of runway
Flaps - Lower as needed
Forced Landing
Complete power failure Max gliding distance airspeed - 63 Fuel shut-off valve - off - pull up Flaps up to maximize glide range Radio - mayday 121.5 (or freq in use) Attempt to position aircraft approximately 1000 feet AGL when on downwind & abeam intended point of landing Ignitions both off On final approach - airspeed 60 (55 min) and flaps down after landing point assured Master off Open canopy Touchdown with min airspeed
Ditching
Forced landing over water - follow Forced Landing procedures plus:
Land into wind if high winds are evident or parallel to swells with calm winds.
Flaps up
Unlatch canopy
Contact water with nose-high attitude
After full stop exit aircraft
Severe turbulence
Do not exceed 108 kts. To minimize discomfort, decrease CAS below 90 kts. Maintain level flight attitude as pitot-static indications may become erratic.
Stall Recovery - what flight control is most effective and what actions should you take?
Rudder is far more effective than ailerons in stalled condition.
Lower nose
Throttle open
Use rudder for lateral control
Spin Recovery
PARE Power out Ailerons neutral Rudder opposite Elevator Forward Once rotation stops, Rudder - neutral Raise nose to level flight
Runaway Trim Motor
Pull trim fuse ASAP
Stabilator - hold against out of trim condition
Airspeed may be reduced to lessen amount of force required for level flight
Land as soon as possible
Soft Field Take-Off
Flaps - 1st detent
Do not stop - remain on the move into take-off roll
Raise nose to take-off attitude (keeps weight off front wheel)
Lift off as early as possible
Remain in ground effect until airspeed allows for climb
Flaps up after 500 AGL
Slow Flight
Reduce power and allow a/c to decelerate to 60 kt IAS while maintaining altitude.
Trim
Adjust power to achieve target airspeed while maintaining altitude
Power-Off Stalls
Power to idle
Maintain wings-level flight while increasing nose-up attitude to maintain target altitude until aircraft stalls
Power-On Stalls
Establish full power, wings level climb at 65 kt IAS
Increase nose-up attitude by approximately 15 degrees an maintain that attitude as airspeed decays to stall
What are the Primary Flight Controls?
Ailerons (Flaperons on RV12) (roll)
Rudder (yaw)
Elevator (Stabilator on RV12) (pitch)
What are the Secondary Flight Controls?
Flaps (Flaperons on RV12) Trim Systems Leading Edge Devices Spoilers Secondary flight controls improve performance characteristics
What do the flaps do?
Create the lift necessary to maintain flight at a slower speed. They also increase drag.
What does the Stabilator do?
It’s an upside down airfoil - a pitch control surface.
Creates downward lift/force
Landing gear/Brakes/Steering
Tricycle gear
Brakes??
Castering nosewheel allows for steering using brakes
Fuel/Oil/Hydrolic
100LL or avgas only - a/c holds 19.8 gallons
Oil - sport weight - must be up to indentation on stick
Electrical system
Not sure what to say about this yes. Backup batteries?
Avionics
Dynon Skyview system - not sure what else to say about this either??
Pitot-Static system, vacuum/pressure and associated flight instruments
Pitot system is comprised of the pitot tube, static port and instruments:
Altimeter
Vertical Speed Indicator
Airspeed Indicator
What are the 3 gyroscopic instruments?
Altitude Indicator
Heading Indicator
Turn Indicator/Coordinator
