5. Limitations:
A. Standby Electrical System:
When the Standby Electrical System is in operation, the following
limitations apply:
(1) Minimum HP RPM:
Minimum HP RPM when the Standby Electrical System is in
operation is 67 percent HP RPM.
(2) Use of Speed Brakes:
Speed brakes may be used, however, operation should be slow
(approximately five (5) seconds for full range movement).
(3) Landing with Standby Electrical System Operating:
Landing is approved provided automatic ground spoilers and thrust
reversers are not used for landing. See Section 05-17-50, Landing
With Standby Electrical Power System Operating.
B. APU Alternator Electrical Load:
(1) Airplanes SN 1000 Through 1155 Without APU LOAD Meter
Installed:
The APU alternator can deliver 100% electrical power (30 kVA) on
ground or in flight from Sea Level to 22,000 ft. From 22,000 ft to
30,000 ft, the limit load decreases linearly to 50% electrical power
(15 kVA). Load shedding may be required. See APU ALTERNATOR

ELECTRICAL LOAD (For SN 1000 thru SN 1155 without APU
loadmeter) in Section 05-04-20, APU Inflight Operation: Alternate
Electrical Source.
(2) Airplanes SN 1156 Through 1429, And SN 1000 Through 1155
With APU LOAD Meter Installed:
The Increased Altitude APU alternator can deliver 100% electrical
power (30 kVA) on ground or in flight from Sea Level to 30,000 ft.
From 30,000 ft to 35,000 ft, the limit load decreases to 67%
electrical power (20 kVA). Load shedding may be required. See
ELWS/ASC 420 APU ALTERNATOR ELECTRICAL LOAD
ENVELOPE chart in Section 05-04-30, APU Inflight Operation:
Alternate Electrical Source - ELWS (Loadmeter) / ASC 420
Procedures.
(3) Airplanes SN 1156 Through 1429 Having ASC 420 (Removal Of
APU LOAD Meter), SN 1000 Through SN 1155 Having ASC 420,
And SN 1430 And Subs:
With the ram air scoop installed over the APU inlet door, the APU
alternator can deliver 100% electrical power (30 kVA) on ground or
in flight from Sea Level to 30,000 ft. From 30,000 ft to 35,000 ft, the
limit load decreases to 67% electrical power (20 kVA). Load
shedding may be required. See ELWS/ASC 420 APU
ALTERNATOR ELECTRICAL LOAD ENVELOPE chart in Section
05-04-30, APU Inflight Operation: Alternate Electrical Source -
ELWS (Loadmeter) / ASC 420 Procedures.
