Q

What are the components of the ADAHRS?

A

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

Q

How will we know when the Autopilot has failed its automatic preflight check?

A

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!

Q

How is the ASPEN EvolutionBD powered in normal and abnormal operations?

A
  • 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.

Q

What allows us to utilize FOB Sync in the Archer?

A

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

Q

Tell me about the Electrical System of the Archer!!

A 
28V System
Components:
- 24V Primary BATT
- 24V EMER BATT (isolate by diode to prevent discharge when alternator is off)
- 28V 70A Alternator

Q

Why do we care if the BATT has 23.3V before flight?

A

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!!

Q

What does the Primary BATT power?

What does the EMER BATT power?

A

Primary:

  1. Starter
  2. ESS BUS
  3. NON-ESS BUSS
  4. Lighting BUS

EMER:
1. EMER BUS

17
Q

Tell me about the alternator

A
  • Belt driven
  • Once running with the ALTR switch ON, it is the primary source of electrical power for the aircraft
  • Will take itself offline if 32V output is produced
18
Q

What is on the EMER BUS?

A
  • Aspen EBD
  • PFD Functions (NAV 1/COM 1)
  • Audio Panel
19
Q

When using the alternate static source, how must you configure in the flight deck?

A
  • Cabin vents/storm window CLOSED

- Heater/Defrosters ON

20
Q

Engine?

A 
IO 360 B4A - 180hp
4 cylinder
horizontally opposed
direct drive
normally aspirated
fuel injected
21
Q

Are the Apsen EBD and G1000 independent of eachother?

A

Yes
The Aspen’s purpose is to provide a reference to crosscheck the G1000 system info/reliability, and in the event of a failure a flight instrument backup. (7-45)

22
Q

Min and Max oil?

A

2 qt min, 8 qt max!

All temps 15W-50 or 20W-50

23
Q

GFC700 Autopilot Limitations? (there are like 7)

A

Must be disengaged:

  1. During TO/LD
  2. Below 400’ AGL after TO
  3. Below 1000’ AGL in cruise
  4. Below 200’ AGL on an Approach
  5. Below 70 KIAS and above 140 KIAS
  6. Below 75 KIAS on Cat. 1 approach only
  7. Over 10 gal fuel imbalance
24
Q

VFR traffic pattern:

A

95 on downwind
Abeam power 1500rpm, flaps 10
75 on base, flaps 25
66-70 on final, flaps 40 or as required

25
Q

Power off 180
