Ice and lots of stuff Flashcards
Are we Anti-Ice or De-Ice
anti-ice
can we fly into known icing? why?
yes we can
because we can get out of it
what are our ice detectors
rotary cutter ice detector on left forward fuselage
ice detection light
what is the delay on our ice annunciator
60 seconds
Where does the TKS fluid come out of
the front of the wing and horizontal stab leading edge
how much TKS fluid do we hold
10 gallons
how many minutes should we have available of TKS fluid
108 minutes used correctly
primed 2 minutes prior to flight
don’t let the 2 minute timer run out - the first minute more comes out - resetting will just cause more to be pumped minute every time
at what temperature should TKS be turned off
-28C
ice crystals no moisture
TKS will leave a gel on the wing and will decrease lift
Are the windscreens and side screens heated
yes electrically by engine-driven alternators
What does alternator 1 heat windshield wise
left windscreen
right sidescreen
left stall vane
What does alternator 1 heat windshield wise
right windscreen
left sidescreen
right stall vane
what happens if an alternator fails
remaining alternator powers both windscreens but the sidescreens are not heated
how are the pitot vanes heated
elecrtically
are the static ports heated
upper static port is heated electrically
lower static port is not heated - slab is welded on behind it to stop ice from forming
How are the engines heated
bleed air from their engine
powered closed
limitation for enigne nacelle anti-ice
more than 10C you can not have on for more than 10 seconds
P2T2 is
electrically heated
TKS system
a weeping wing system
anti-ice fluid (TKS) is pushed out of tiny holes in the wing and horizontal stabilizer. it is pushed over the wings by the wind and prevents icing
Hot wing system
pushes hot air from the engine into the front of the wing to help melt the ice trying to form on the wing
Boots system
inflatable boots on the front of wings. it inflates when activated to knock ice off of the wings
different form of ice detecting device
the temperature that is normally set in Gauge C
65 to 88
the temperature that is available in manual
6C to 116C
the temperature that is normally set in DUCT OVHT
116C
how do we control cabin pressure
by the amount of air we let out of the cabin
7500 @ FL 410 + psid
8.55
max cabin differental pressure
8.55
max negative cabin pressure
-.5
