Anti Ice And Rain

Icing speed logic for speed bars

Stall protection

Pnuematic

Bleed air duct, valves AC pwr

3 nboard slats

Outboard slats and Le flaps not protected

No 1 only

Probe not heated.

Note: if op on Stby pwr lights don’t indicate

On: power supplied

Auto: power supplied when either engine running

PTA - pitot TAT alpha = electric

SST - Static, Standby AIrspeed temp = not heated

Captain pitot all that’s heated in Stby but no indications it’s failed

7 seconds

10C and visible moisture

Cloud, vis 1SM, precipitation, snow, slush or water on runway.

Start switches to cont

Eng anti ice switches on

Check cowl anti ice bright then dim, check TAI on N1

Turn eng anti ice switches off

Both engine ignition to auto

Engine thrust below TO warning lvl

No high duct temp

If either above occur valve closes but switch stays on.

Trips off at lift off.

Wing anti ice control valves open.

Icing Stock shaker logic on and stays on for whole flight

Over pressure downstream of cowl anti ice valve

Bright blue means pos disagree

Selected on: valve isn’t open, avoid icing.

Selected off: valve stuck open, engine affected side N1 limit to 80%

Turn off, wait 2-5 , turn on, if it reoccurs turn off

Limited to 259 below 10

On: failed closed. Avoid icing.

Off: failed open. You shut down system so no icing prot on failed side

Closes: Both bleed on and both pack high/auto

Open: either bleed or pack switched off

1 in air and 2 on ground

1

Duct ovht or failure of sensor

Pack temp exceeded limits, drives full cold air. Requires reset.

Packs switch to high flow

Opens on ground or slow fight with flaps not fully retracted

BHAB

Bleed (hot) - heat exchanger (warm) - air cycle machine (cold) - additional bleed air for temp correction.

Trim air on = normal

Trim air off = average for all zones

Both pack normal = both

1 on high = left off

Both high = both off

Both hi (ground) = left off

Descent to 10000 and keep speed above 290 due temp increase. Open outflow valves

Light comes on, alt fan kicks in and extinguishes within 5s

Both packs = low

One pack operating= high in flight w flaps up

One pack from APU and both bleed off = high no matter flaps or alt

If fault is corrected resets

Bleed trip off

Pack

Zone temp lights

Descent before planned cruising level

Descent before planned cruising level

Duct leak in engine, wing or aircon bay

Excessive air temp or pressure Bleed air valve closes automatically.

No use of wing anti ice above 350 or this happens and you can lose pressure oh cabin!!!

Bleed: DC activated and pressure op

Isolation : ac operates

Engine thrust limited to idle

Outflow valve

Exhaust port: low diff pressure ( on ground) E and E exhaust is dumped. High diff pressure it’s diffused in cargo lining.

Auto stored in memory for next take off altitude

If ALTN green: one system failed but other taken over

No ALTN: both have failed

Protect you fromOver or under pressure condition. Prevents external pressure exceeding internal on fast descent.

Info : ADIRU, TL position and Air ground switch

Power: DC controls the outflow valve

Closes with high pwr

Within 0.25 cruise mode

Once 0.25 below flight alt prop descent

Slight pressure to avoid large changes. After landing opens fully

Seperate DC system

ROC less 20s full mvmt

Turns comms panel off and illuminates white

Success : tune heard for 7s

Fail: 8-15 seconds

120 mins

Eng start to 5 min after last shut down

On records immediate then trips to auto

Only com 1 capt or 2 go heard at pre defined volume. No other Chanel or warning md

Turns comms panel off and illuminates white

Only com 1 capt or 2 go heard at pre defined volume. No other Chanel or warning md

Turn all to flt and identify source

No it bypasses the bleed valve to go directly to cowling

Not automatic for icing cond, just stick shaker logic and min manoeuvre speed bars

10 mins

Supp run up procedure req

Wing must be on too

Wing must be on too

Wing: reduces clean and dirty ( flap out)

Engine: only reduces dirt (flap out)

Colder than -40 SAT not needed, even in vis moisture.

Descent it’s on

Terminates the satcomcall

Activates: Left boom door

Deactivates: left boom door closed and reset switch pushed

Through the cdu

25 hours

400fpm

Pack is temp

Bleed is over temp and overpressure
