procedure.
85
When do the IRU's shed on a non-ER aircraft?
- If left and right main AC buses are lost, all 3 IRU’s
go to HBB, after 5 minutes left & center shed, right
stays on HBB until battery is dead.
-- If left main AC bus is lost: left & center IRU’s go to
the Hot Battery Bus (HBB) and run on DC power, no
time limit since battery charger is still powered from
right AC, right IRU remains on right AC.
-- If right main AC bus is lost, the right IRU operates
on HBB until battery is depleted (approx. 30 min), left &
center remain on left AC
86
How do the IRU's shed on anER aircraft?
- If left and right main AC buses are lost, all 3 IRU’s
go to HBB, after 5 minutes right IRU sheds, HDG
powers left & center IRU. (If no HDG, left & center stay
on HBB until battery is dead).
-- If left main AC bus is lost, left & center IRU’s go to
HBB and stay there (no battery time limit since battery
charger is still powered from right AC), right IRU
remains on right AC.
-- If right main AC bus is lost, (right DC will also be
lost) right IRU operates on HBB and sheds after 5
minutes, left and center IRUs remain on left AC.
