Altn brake check 320
hi,
on our 320's (MSN 2000 series) when you perform the altn brake check at the gate before engine start the brake pressure is automatically limited to 1000 psi.
it states also in FCOM3 that the altn brake check is not required.
however there have been times when i have done the brake check ive seen the pressure being limited to 1000psi and sometime it goesto around 2000-2700psi.
any reason as to why this brake pressure varies?
thanx
