What does the ACS bleed air -> INHIBIT do?

Why would you do this on takeoff?

What does the ACS emergency shutoff do?

A

Closes primary shutoff valve

On short field takeoff to provide more takeoff power

Closes firewall shutoff valve and opens emergency air duct to provide fresh air

Q

IGS Systems

How does the torque limiter work?

A

If engine producing too much power, need a way to tell FCU to produce less

Py is the way to do this - under normal conditions Py = P3

When Py gets too high (> 44.34), torque limiter will bleed off some of this to trick FCU into thinking pressure in engine decreased, therefore less power, so FCU meters less fuel
