An ECAM GPS 1 FAULT annunciation is inhibited during

• A. Cruise
• B. Takeoff and landing
• C. Descent
• D. Climb

Answer: (B)

Takeoff and landing are high-workload phases, so the ECAM system suppresses certain fault messages to avoid cluttering the crew’s workload. The GPS 1 FAULT annunciation is one of those suppressed during these phases. A GPS fault can be transient due to satellite geometry or reception, and flight safety isn’t compromised by delaying this warning until other navigation options aren’t as critical. Once you’re out of takeoff/landing, the fault will be shown so it can be addressed.
