40
When and where can you use the electric heat subsystem?
On the ground with external power
41
When and where can we use the VCCS?
Primarily on the ground, on the ground or in the air, 2 generators or external power, keep in mind, at transition altitude, windshield heat goes to LO and VCCS must be off and no tail anti-ice
42
When and where do we use the pitot heat?
Used all the time, anytime in the air, used to eliminate erratic operation of the mach speed indicator.
43

Anytime above FL180
46
If windshield heat is in high
Mag compass gets screwy and distorts the windshield

Greater than 200°
48
Cabin air overheat
Greater than 390° +/- 15°
49
How do you use the stab de-ice backup?
Hit the switch momentarily every 2 minutes and activates it for 30 seconds and only heats the gap. Cannot be used with the normal de-ice or anti-ie and flaps 10.
50
Cabin rate of change knob goes anywhere from
50-2000fpm, 12 o'clock is 500 fpm, 10 o'clock position is around 300 fpm
51
Full decrease on cabin rate of change knob
12,500 +/- 1500. Caution: Be careful be slow, could cause a rapid decompression and damage your ears.
52
Cabin Manual Pressure Controller
To completely dump the pressure, use the cabin dump valve (under the cabin panel)
53
How do we de-ice the horizontal stab
Hit the switch on the overhead panel. Uses electricity
54
What has to be pulled for the back to get oxygen?
Pull the Pass Oxygen knob
55
Maintenance need to service the oxygen system if?
The green disc is visible
56
What is normal oxygen pressure?
1600-1850psi
57
When climbing to higher altitudes
Keep in mind the oxygen system will show less pressure because cool air has less pressure
58
Radar attenuation
Amount of precip and distance
59
What function can you use to discriminate between heavier and lighter bands of weather?
Gain
60
What is the range on the weather radar?
5-300 miles
61
How do you adjust range when using the mfd
Use the LSK keys, bottom right of the MFD
62
If overlaid weather on HSI
Use the RNG knob on the DSP panel (Format: HSI ARC MAP)
63
Normal sweep on the weather radar?
60° left and right of center
64
Sector scan
30° left and right of center
65
Weather radar tilt
+/- 14 degrees in .25° increments
66
When at cruise and operating in level flight
Tilt is set below the freezing level because it picks up liquid better than ice. Tilt it down so ground returns are shown on the outer third of the display
67
Which radar antenna as a more focused beam?
Flat plate and we have it on the T-1A
68
What is a PAC alert?
Path attenuation correction, radar notifies you it can't see through the precipitation. Yellow arc or box will appear in that area.
69
What precip has the most reflectivity?
Wet hail
70
Four different colors of the radar returns
Green-light, Yellow-moderate, Red- Strong to intense, Magenta- intense to extreme
71
Prior to departure, if we are expecting to fly into weather, how do we set the radar?
+5 to 7 on the tilt, 50nm range, allows you to see slightly below, in and above the flightpath
72
What does the hold function of the weather radar?
Allows to freeze the weather radar picture for up to 5 minutes. Good to show direction (he was looking for direction) and development of a storm
73
Paddle for the yaw damper and autopilot
Yaw damper can be on by itself, autopilot switch turns on yaw damper, autopilot will never be on without the yaw damper, Interlocked AP needs YD, but YD doesn't need AP.
74
The go-around switch on the left throttle
Generates a fixed 10° pitch up and holds current heading. Disables the autopilot, does not disengage the yaw damper
75
Flight director is set in the heading mode
The command bars are going to steer you to EHSI heading bug position
76
We can set up autopilot to chase an ILS
If you intersect glidepath and then try to adjust the pitch knob, nothing happens
77
Approach mode and autopilot captures the localizer
It ignores commands in from the roll knob
78
Changing the departure base in the FMS
It dumps the flight plan if you're on the ground. If you're airborne, you cannot change the departure base.
79
If autopilot is engaged, it also engages the flight director
Buy you cannot turn the flight director off, button doesn't work
80
At the top of EADI, what is displayed if the autopilot
Lateral and vertical modes of the autopilots. Defaults to roll and pitch if nothing is selected on the autopilot
81
The active nav sourse, other words what you're looking at on the HSI?
Display select panel (DSP). If you select appr on MSP, it'll go with what's in the the DSP.
82
LVL CHG button does what (Airspeed hold button)
Auto Pilot and flight director will chase whatever indicated airspeed (moves airspeed bug) to whatever is set in the altitude preselect
83
What codes does GPS use?
PRN (Pseudo Random Noise) Code
84
The GPS changes sensitivity on the CDI depending on where you are
Enroute (5nm full scale deflection/outside of 30 miles from your destination)
Terminal (1nm full scale deflection/inside of 30 miles from your destination)
Approach (.3nm full scale deflection/inside of 2nm from FAF)
85
If you go missed approach
GPS reverts back to terminal display
86
If you go missed approach
FMS must be sequenced using the go around button
87
Where would you find a list of inop satellites
Type in KGPS on any NOTAMS display
88
Must check NOTAMS for a GPS approach
Deselect the GPS satellites that are down
89
If you're going to fly a GPS approach
Must pull them from the FMS database, cannot upload points off approach plate
90
Autopilot defaults to chasing the pilot's flight direction
Move it to the copilot's flight direction using the AP XFR, autopilot transfer button. Confim using the ADI top left corner, AP/L means pilot, AP/R means Copilot
91
How do you disengage the autopilot
1. Trim interrupt & AP Disengage Switch-turns off AP and YD
2. Use the switches to-disengage AP and not YD
3. Pitch or roll trim-Disengage the AP/not YD
4. The Go-Around button kicks off the autopilot, inside left throttles-YD stays on
