Inverter failure
Sg 5, fr 39
Single/Double Inverter
a.
Single inverter failure
Failure
(1) AC INV caution light illuminates (along with
MASTER ALERT and caution tone)
(2) GENERATOR warning light remains off
(3) Loss of non-essential AC services
b.
Double inverter failure: indications same as
single inverter loss, except all AC services are
lost
(1) If reset of AC inverter not possible, TACAN
azimuth, and GINA will be lost due to loss
of VAC
(2) Requires use of standby instruments for
IMC
NOTE: The standby attitude indicator does
not depend on aircraft AC inverters. It will
continue to operate with 28 VDC supplied
from the 28 VDC essential services bus.
(3) Maintain VMC if possible and land as soon
as practicable
(4) Normal instrument approaches
impossible -- limited to radar approaches
