SY203 Flashcards
What are the three EFIS modes?
Approach, enroute and composite
How are the course set on the EHSI?
Using the HDG and CRS knob on the EFIS control panel
EFIS approach mode adds what elements to the standard instrument displays?
Glideslope
Localizer
Marker beacon
What are the pitch and roll parameters that cause the EFIS to declutter the EADI during unusual
attitudes?
+30/-20 pitch, 65* bank
When will the EADI return to normal (pitch / roll)?
+25/-15, 60*
What is the purpose of the VSI?
Show direction and range of climb/descent
What information does the airspeed indicator display?
Airspeed
V(mo)
Mach
As altitude increases what does the airspeed indicator show?
Decrease in V (mo), barber pole move downward
How can you tell the ACD have failed or its data is invalid?
ACD fail will be indicated in the instruments
What are the standby instruments?
Airspeed indicator Attitude indicator Altimeter Turn and bank indicator Magnetic compass
How are the stand by instruments powered?
Battery bus
Auxiliary battery
How is the standby airspeed indicator operated?
By pitot and static pressure from the pitot/static system.
When should you cage the standby attitude indicator?
Before applying or removing the electrical power
Before engine start and shutdown
After loss of all electrical power, how long will set standby attitude indicator provide pitch and roll information and to what accuracy?
9 minutes / 6*
At how many knots above stall speed is the stick shaker activated?
Approximately 5-10 knots above
What does the green arc on the AOA gauge indicate?
Normal approach speed (optimal AOA or ‘on-speed’)
What are the thee operational modes for the EADI and EHSI?
Enroute, approach and composite
When will either the MASTER WARN/CAUTION switch lights illuminate?
A. Anytime a warning or caution annunciator illuminates in either cockpit
B. The MASTER WARN switchlight will illuminate with the FIRE light
The VSI displays vertical velocity from 0 to how many FPM?
6000 FPM
From what component does the ASI receive its data?
ADC (Air Data Computer)
The standby instruments are normally powered by what?
The battery bus
When showing, what does the red indication in the standby turn and bank indicator mean?
Turn rate information is not available (the slip indication will still work)
When should a reading be taken from the magnetic compass?
Level and unaccelerated flight
When does the AOA amber donut illuminate?
When you have achieved the optimum AOA for landing (on-speed)
What is the purpose of the two resettable needles on the accelerometer?
Record maximum deviation above and below +1 G during flight
What happens anytime the FIRE warning annunciator illuminates?
MASTER WARN switchlight flashes
MASTER WARN tone sounds
What sound is:
250 Hz tone
5 times per second
Landing gear position warning
What sound is:
1600 Hz tone
5 times per second
Over speed warning (Vmo/Mmo exceeded)
What sound is:
Six tones per second for two seconds
NACWS landing mode alert
What sound is:
Three tones per second for two seconds
NACWS enroute mode
What sound is:
Decaying tone
MASTER WARNING/CAUTION, FIRE
