(O) Aeroplane may be dispatched with one (1) valve inoperative provided:
a) Affected Valve is verified OPEN,
b) All components of both HP Bleed Air Systems are operative,
c) Both Environmental Control Systems (ECS) Packs are operative,
d) Affected Cowl Anti-Ice switch is ON,
e) Affected L COWL ANTI-ICE: LEER, D-3 or R COWL ANTI-ICE: REER, D-14 valve circuit breaker is pulled or in the OPEN position. Flight crew may accomplish this task if properly qualified and authorized,
f) Performance Computer is initialized with COWL ANTI ICE selected ON for either takeoff or landing when COWL ANTI-ICE valve is pressurized, and
g) Aeroplane is operated in accordance with AFM Limitations and Performance.
Flight crew will ensure:
BOTH HP Bleed Air Systems and BOTH Environmental Control System (ECS) Packs are operative,
Select the affected Cowl Anti-Ice switch ON and ensure that the affected valve circuit breaker is pulled or in the OPEN position, and
Flight crew verifies that fact by viewing the ECS synoptic page to see that Cowl Anti-ice pressure is indicated. There will also be an A/I icon in the TGT instrument
