A 
Oil pump and reservoir 
Alternates for N1 control amp
ED hydraulic pump
ED fuel pump and fcu
IDG
ATS
N2 indication
18

A

Increases thrust approx 2%. 8779 to 9220

Can be used for 5 minutes

21
Q

TO restrictions with regards to APU, ice

A

If ice on, APR must be operative

If no APR, packs must be off for TO if ice on

22
Q

When does the start sequence end

A

55% N2

23
Q

Where does ignition get power

A

A is AC Essential

B is battery bus thru static inverter

24
Q

Required for TR use
