Flaps 40 = rudder is __ degrees L/R of center
-Auto when flaps down and turning (older planes)

Limited to +/-12 but can go +/-60 with differential and power = 33’6” turn radius
Trim:
___ Operated by ___ or ___ inputs.
__ trim is only operated by the pilot
Electrically operated by manual or autopilot inputs
Aileron trim is only operated by the pilot
Pitch Trim:
- Pri is ___ VDC main motor off the __ bus
- Sec is ___ Bus A/P Trim Adapter (used by __ and __)
- Using trim engage trigger or ____ trim rocker switch will ____ the autopilot but not the ___
- 28 VDC off the batt bus
- Sec is the AV 2 Bus, used by the Autopilot and Alt Stab Trim switch
- Using trim trigger or alt stab trim will disengage the A/P but not the YD
Red [STAB TRIM] and “Warning Trim”
- ___” after WOW
- ___” after start
… if trim is unsafe for T/O
- 60” after WOW
- 120” after start
Rudder trim:
___ VDC
3-position switch on front of ___
Will / Will not disengage A/P
28 VDC
Switch on front of PCL
Will NOT disengage A/P
Flap asymmetry/twist:
- If asymmetry > __ difference, then Flap Control Warning Unit will de-energize the ___ and illuminate red [FLAPS] on CAWS.
- If asymmetry or twist and >__ degrees, then …(A)__, (B)__, (C)__
- > 5 degree asymmetry locks the Power Drive Unit (4 actuators, 2 per flap)
- Asymmetry or twist >2 degrees, then (A) stick pusher to “Safe Mode,” (B) Amber [CAWS PUSHER], and (C) Shaker/Pusher 5 kts higher for the failed flap positions
Flap Airspeed Ops Limits
15:
>15
15: 165 KIAS
>15: 130 KIAS
- Shaker will activate if __ AOA channel is approaching stall (_ to _ Kts above stall)
- Pusher will activate if __ AOA channel indicates approach to stall (- kts above stall)
- If either activates, the ___ is disengaged
- Shaker if 1 AOA (5-10 kts above stall)
- Pusher requires both AOA channels agree (2-5 kts above stall)
- Both will disengage the autopilot
Pusher Ice Mode:
- Active when ___ on
- Computer reduces defined AOA by __ degrees.
- Flaps limited to __ or __ degrees (by pilot)
- If green ___ CAWS does not illuminate, ____will illuminate and the pusher will be ___.
- Active when engine de-ice (inertial sep and prop ice) on
- 8 degrees
- 0 or 15 flaps only
- If green [PUSHER ICE MODE] does NOT illuminate, then Red [PUSHER] will illuminate and pusher will be disabled.
Sources of \_\_VDC: 1)\_\_ 2)\_\_3)\_\_4)\_\_ Source of \_\_VAC: \_\_ - Provides \_\_ VAC at \_\_ Hz - 1 powered by \_\_ Bus, 2 powered by \_\_ Bus - \_\_\_ which powers system after start
28 VDC by Batt, Gen 1, Gen 2, External
26 VAC by DC inverter
Source of 26 VAC: Inverters
- Provides 115 VAC at 400 Hz
- 1 powered by Batt Bus, 2 powered by Gen 1 Bus Bar

- __ min < __ amps (double batt: __ min)
Double gen fail = batt supplies for
20 min <60 amps (40 min)
30 min <50 amps (60 min)
1) Min VDC to start
2) Batt < __ Volts = [LOW VOLT] amber CAWS
3) Over-charge if __ amps
4) Over-volt if >/= __ V
1) 24 VDC min to start
2) Batt <18 V = [LOW VOLT]
3) Over-charged if >60 amps
4) Over-volt if >/= 29.5 V
EPS (Emer Pwr Supply) designed for __ min after loss of main elect and batt. Provides __ V and __ Amp Hr
