APU Master...................................................................ON/WAIT 3
SECONDS/
START/THEN ON
Turn the knob to ON, wait 3 seconds, and then momentarily to
START. Monitor APU EGT and RPM increasing within limits. The
APU generator will come on line after RPM exceeds 95%.
GPU .............................................................................. OFF
Crew must deselect the GPU as soon as the APU is running and
stable to prevent the ground crew from disconnecting it while still
selected, which causes an unwanted transient.
Avionics Master 1 & 2 .................................................. ON
Switch the avionics master to ON. Verify APU voltage and
amperage on electrical page. Amperage may be greater than 400 A
(APU GEN OVLD may appears on the EICAS) at first while the
APU recharge the batteries. Do not bring any additional load on line
until amperage is below 400 A. Allow a few seconds for the APU
GEN OVLD message to disappear before switching the avionics
master to ON.
Turn the NAV lights ON, be it daytime or nighttime. NAV lights ON
show the ramp personnel that the airplane is powered up, and also
make wingtips and tail end more visible to people driving vehicles
in the proximity of the airplane.
The LOGO light may also be switched ON during nighttime.
Allow 3 minutes of APU warm up before adding pneumatic load.
APU Bleed..................................................................... OPEN
Air Conditioning............................................................. AS REQUIRED

- Both Packs ON;
- XBLEED to OPEN;
- Set both temperature controls to AUTO. If control of the
PACK 2 by the cabin attendant is desired, select the
corresponding knob to ATTD. Recirculation and gaspers fans
will be on;
- Shed Buses must be set to OVRD to operate the
recirculation fans when the electrical system is energized by
the APU generator.
