3.10.2 Battery discharges (BAT)
Warning light
ENG
(RED) with ammeter values
ALT1
and/or
ALT2
shown in RED and thus
BAT
shown in YELLOW (with or without
ALT1
and/or
ALT2
warning light is illuminated)
If an ammeter value for BAT is shown in YELLOW on the MVP, the power supply of both
alternators into the on-board electricity system is insufficient - Battery is discharging.
1. Ammeter
CHECK for defect Alternator(s)
for
ALT1
acc. point 3.10.3
for
ALT2
acc. point 3.10.4
if
both alternators are defect
:
2.
Fuel Pump AUX
switch
CHECK, if ON
3.
ALT1
switch
CHECK, if OFF
4.
ALT1
circuit breaker
CHECK, if PULLED
5.
ALT2 / BAT2
switch
CHECK, if OFF
6.
ALT2
circuit breaker
CHECK, if PULLED
7.
ALT2 Disconnect
circuit breaker
CHECK, if PULLED
8. Brightness level of all additional instruments not necessary for the safe continuation of the
flight has to be reduced to half or the instruments have to be turned off.
9. Ammeter and voltmeter
MONITOR
10. Precautionary Landing
PERFORM (see 3.4.1)
WARNING
The MAIN fuel pump is no longer supplied with electricity in case alternator 2 (ALT2) has failed
and the fuel pump is separated from the remaining on-board power supply by turning ALT2
switch off. In this case the AUX fuel pump is the only fuel supply for the engine.
WARNING
A properly maintained and fully charged battery alone is able to supply all necessary systems
with electricity for at least 30 minutes. The illuminating of the ENG (YELLOW) warning light with
BAT ammeter values shown in YELLOW are indicating the beginning of the 30 minute period.
After 30 minutes engine failure due to failure of the remaining AUX fuel pump has to be
expected.
