When should ignition be selected on for takeoff?
Contaminated runway
Heavy rain
Turbulence expected

When does SRS engage and what does it do?
Engages when thrust levers set to TOGA or FLX as long as:
V2 is entered in PERF page
slats are extended
A/C has been on ground for >30s
SRS flies:
Pitch to maintain V2+10 for 2 engines
Pitch to maintain greater of V2 or current speed (max V2+15) for single engine
SRS also limits pitch to 18º or 22º in windshear
What is GA SOFT?
Set TOGA thrust on go around and then back to FLX/MCT. SRS will maintain approx 2000fpm
