A 
! After setting Engine AI on, if cowl A/A stays bright with engine Idle
SP16
Check APU BLEED IS OFF
check ISOL VALVE IS AUTO
check acft clear and increase N1-> 30%
29
Q

Icing conditions on the ground

A

Icing conditions on the ground
use WAI between start and T/O unless protected by Fluid Type II or IV
WAI-on (may cycle on-off due loic)
WAI automatic off when T/O thrust is set.
preliminary use is de-ice

30
Q

CW: after start, the flaps stop to a different position than flaps lever

A

CW: after start, the flaps stop to a different position than flaps lever
immediately set the set the flap lever in the same position.

31
Q

CW Before Taxi

A

CW Before Taxi
GEN switches on: wait until stabilized (up to 5 minutes needed)
Flight control check after de-icing.
Flaps Test: check full down and back before setting T/O Flaps
SHOULD THE FLAP STOP: position the flap lever immediately in the same position

32
Q

CW TAXI

A

CW TAXI
minimum thrust above standing deicing fluid
Ice Shedding: T<3°,
Check area behind the airplane
70% N1 for 30 sec Every 30 min, (including taxi in)
heavy conditions: 70% for 1 sec every 10 minutes.
after taxi in contamination: do not retract flaps more than to 15°

33
Q

Ice Shedding, résumé des procédures

A

Ice Shedding, résumé des procédures
le fan peut être normalement givré lors de la PPV, si on ice-shed au sol
T<3°, check behind airplane, 70%N1/30sec, 30min.
T<3°, heavy cond: check behind airplane, 70%N1/1sec, 10min.
inflight: Fan Ice Removal SP16IGN: FLT - AT off - 80% 1sec one by one - wait 15 sec. (VIB<4 -> repeat every 15 min or sooner) (VIB>4 -> Engine Vibration Non Normal C/L)
High Engine Vibration NNC

34
Q

Engine run up, CW: recommendations ?

A

Engine run up, CW: recommendations ?
éviter les 70% de N1 1 sec toutes les 10 minutes. difficile sur TW
Enchaîner runup et T/O

35
Q

CW DE-ICING

A

CW DE-ICING
APU (shut down unless necessary due fumes)
Flaps up
Idle - Trim set - Eng Bleed off - APU bleed off
Holdover time: beginning of anti-icing proc

36
Q

CW AFTER DE-ICING

A 
CW AFTER DE-ICING
APU as necessary (éviter si possible)
1 minute wait -> eng bleed ON
Flaps - T/O
Flight control Check
37
Q

! Wing has been de-iced, do we use WAI for Take off ?

A

! Wing has been de-iced, do we use WAI for Take off ?

not if Type II or IV has been applied and is protecting the acft

38
Q

! T/O, icing conditions, T<3°C

A

! T/O, icing conditions, T<3°C

30 sec 70% N1

39
Q

If flight in moderate to sever icing condition cannot be avoided, do:

A

If flight in moderate to sever icing condition cannot be avoided, do:
SP16: CW FAN ICE REMOVAL
IGN: FLT - AT off - 80% 1sec one by one - wait 15 sec.
VIB<4 -> repeat every 15 min or sooner
VIB>4 -> Engine Vibration Non Normal C/L
Use WAI
Use of WAI above FL350 may lead to bleed trip off and loss of cabin pressure

40
Q

A

CW Altitude temp corrections
Correct all minimum altitude inc FAF, app, AD, G/A
except,
between (FAF and MDA) for minimas VNAV (mais respecter tempé mini)
radar vectors or ATC level
T>0

41
Q

CW Shutdown procedure after Lansing in icibg condition:

A

CW Shutdown procedure after Lansing in icibg condition:

stabiliser trim 5 units (avoid water freezing and locking controls)

42
Q

After landing, if contamination or slush, flaps.

A

After landing, if contamination or slush, flaps.

retract flaps to 15 (sp16)

43
Q

CW Secure procedure:

A

CW Secure procedure:
if warm air circulation in the E/E compartiment is required: APU start - gen on - packs auto - isol valve open -press man - outflow open.

44
Q

Moderate to heavy Rain, Hail or SLeet (neige fondue)

A

Moderate to heavy Rain, Hail or SLeet (neige fondue)
Ref SP16
IGN CONT
A/T OFF , adjust thrust manually, slower than AT, do not change direction until stabilisation. maintain minimum thrust setting
Reduce speed
consider Start APU (why ?)
