Anti-ice and Flight Controls Flashcards
Fully automatic ice and rain
protection is provided for which
systems
Wing leading edge
Engine cowls
Windshields and side cockpit windows
Air data probes, sensors, and
YD heater controlled by 2
HBMU’s which also monitor
The 4 BTMS units
When the wing and cowl anti-ice
is set to AUTO, when does the
anti-ice operate
When the ice detector system
detects ice
note:
both sensors must sense ice before
CAS is posted
When is the AUTO feature of the
anti-ice system inhibited
On the ground
During take off
Below 400’
If there is a failure of one of the two
wing anti-ice systems, under what
condition will the wing cross bleed
valve open automatically
If the WING XBLEED is in AUTO
Below what airspeed are the ice detector
probes ineffective
30 KIAS
which engine bleed source is
used for cowl anti-ice
LP bleed air form on-side engine only
How are the primary flight controls
controlled and actuated
Mechanically controlled
Hydraulically actuated ( PCU’s )
Which Hydraulic powers the
aileron PCU’s
Left aileron, systems 1 and 3
Right aileron, system 2 and 3
Which Hydraulic system(s) power
the rudder PCU’s
Hydraulic systems 1,2 and 3
Which Hydraulic system(s) power
the elevator PCU’s
Left elevator, systems 1 and 3
Right elevator, systems 2 and 3
How many spoiler panels are
located on each wing
4 multi-functional spoilers
2 ground spoilers
With flaps down, which MFS
are available
Only the two inboard pairs of MFS
are available for flight spoilers
note:
max selection of the FSCL has no effect,
roll spoilers on the outboard panels are
reduced, ground lift dump still uses all 6
How is symmetrical lift dumping ensured
when there is a failure of an MFS
panel
The corresponding symmetric panel
on the opposite wing is
automatically disabled
When the ground spoilers are armed,
in addition to the thrust levers being
at idle, what other conditions are
required for deployment
Any 2 of the following
RA less than 7’
One left or right main
landing gear WOW
One left or right wheel speed
greater than 16 knots
