L3 STO Flashcards
Where is the ADAHRS box located in the Archer?
In the tail
What are the components of the ADAHRS?
ADC - pitot static mast, alternate static air, EBDs (Aspen) provide ASI, VSI, Altitude and OAT
AHRS - GPS, rate sensors, air data, and magnetic variation provide pitch, roll, sideslip and heading info
Tell me about the Archer’s main/nose gear, and the hand break
- Mains each have a hydraulically operated External Caliper and Disc Brake Assembly
- Nose gear is steerable 20 deg either side, Shimmy Dampener included
Toe brake and Hand brake have independent Master Cylinders, but share a common reservoir
Why is there a drop in RPM when utilizing alternate engine air induction?
This new air is warm and unflitered!
What are the different levels of CAS messages?
RED = warning AMBER = caution WHITE = advisory
How will we know when the Autopilot has failed its automatic preflight check?
The Electric Pitch Trim will not function!
- To recycle, turn AVIONIC MASTER off and then back on
- On the PFD “PFT” will disappear and there will be no failure indications if test is successful!
What kind of Autopilot does the Archer have installed?
GFC 700
What is CWS
Control Wheel Steering
- will disconnect the AP Servos momentarily allowing you to hand fly
What 4 things will occur when activating TOGA
- AP Disc
- Command a nose up pitch attitude
- Change CDI to GPS mode
- Cycle GPS to MAP procedures
How is the ASPEN EvolutionBD powered in normal and abnormal operations?
- Normally powered by ESS BUS
- During an ALT failure it will operate off ESS BUS until the Primary BATT is depleted. Then EMER BAT/BUS will provide power for 30 mins
- If Primary and EMER BATTs fail, EBD will revert to its own internal BATT provided 30 mins additional.
If any part of the Aspen EBD is inoperative, can you fly IFR?
No - IFR flight is prohibited when any component of the EBD is inop
What allows us to utilize FOB Sync in the Archer?
There is 1 float type sensor in each wing tank. Signal is measured and send to the GEA (Garmin Engine Airframe) Interface where it is converted to a fuel quantity
Tell me about the Electrical System of the Archer!!
28V System Components: - 24V Primary BATT - 24V EMER BATT (isolate by diode to prevent discharge when alternator is off) - 28V 70A Alternator
When will the EMER BATT provide power to the EMER BUS?
When the EMER BATT switch is in the ARM position and there is an electrical system fails
Why do we care if the BATT has 23.3V before flight?
23.3V charge guarantees 30 mins in flight if total elec failure. If less than 23.3 this means battery needs to be recharged, or replaced!!
