Sys 201 - Flight Instruments Flashcards
The T-6 has the capability to navigate via ____ and to fly ___ and ____ approaches.
VOR; VOR; ILS
Where is the navigation receiver located?
In the right avionics bay
Where are the antennas for the T-6 located?
Vertical fin and on the bottom of the fuselage
What are the types of instruments on the T-6?
- Electronic Flight Instrument System (EFIS)
- Air Data System (ADS)
- Standby Instruments
What does the EFIS consist of?
- EADI
- EHSI
- EFIS Control Panel
What does the AHRS provide?
Aircraft attitude, headings, and flight dynamics information to the aircraft systems and displays
What are the three EFIS modes?
- Enroute
- Approach
- Composite
The EFIS approach mode adds what elements to the standard instrument displays?
- Glideslope
- Localizer
- Marker Beacon
When the AHRS is set to DG mode, what does the EHSI become?
The EHSI becomes a compass card with inaccurate heading information
What three EIDs does the ADS consist of?
- ASI
- Altimeter
- VSI
What component of the T-6 gives the EIDs in the ADS their information?
Air Data Computer (ADC)
Where is the primary pitot probe located?
The right wintip
Where is the secondary pitot probe located?
The left wingtip
Describe how the primary pitot static system operates.
The primary pitot tube on the right wingtip and the primary static ports on both sides of the aft fuselage route their dynamic and static pressure information to the Air Data Computer located in the left avionics bay. The ADC uses this data to generate airspeed, altitude, and climb rate information for use by the primary instruments.
What does the ADC not provide?
The ADC does not provide information corrected for temperature, position, or instrument error.
How many degrees does each line on the EADI represent?
The scale is graduated in 2.5 degree increments until 30 degrees NH/NL, then the scale is graduated in 5 degree increments
In a standard rate turn, how far is the pointer displaced?
It is displayed the width of one full pointer, or center on the outer box
If the pitch angle exceed ____ or ____, or the roll angle exceeds _____, only the attitude presentation will remain and all other information presented on the EADI will be removed.
When the aircraft returns to a pitch angle of less than ____ up or _____ down and _____ of bank, the normal EADI presentation will appear.
30 degrees or -20 degrees
or the roll angle exceeds 65 degrees.
25 degrees up, or 15 degrees down
and 60 degrees of bank
At what attitudes do the recovery chevrons appear and what do they indicate?
Between 40 and 90 degrees nose high/low
Indicates the nearest direction for a level attitude recovery
If the EHSI is displaying a GPS source, what 4 display objects will pressing the MAP button cycle through?
- Waypoints
- Waypoints with ground stations
- Waypoints with airports
- Waypoints with ground stations and airports
What are the full circle ranges on the EHSI while in NAV MAP mode?
And how does the inner range circle correspond to the full circle ranges?
5 10 20 40 80 160 240 320 1000
The inner circle is the full circle ranges divided by 2
IF you press the ARC button for the EHSI, how much of the compass rose is displayed?
85 degrees
What color represents the outer marker beacon on the EADI?
Blue
What color represents the middle marker on the EADI?
Amber
What color represents the inner marker on the EADI?
White
If heading data becomes invalid, what will the EHSI displays show?
ATTITUDE FAIL and red’x cover the glideslope and localizer indications
What is the VSI range?
0 to +/- 6000 fpm
On the ASI, what is VMO represented by?
The red and white dashed pointer
What is the increment value on the ASI between 40 and 320 knots?
5 knot increments
What is the increment value on the ASI between 320 and 400 knots?
10 knots increments
At what Mach number will the center of the ASI display Mach value?
0.40 Mach
If the ADC fails, what will the EIDs display?
ADC FAIL
