What is the definition of Land as Soon as Possible?
An emergency shall be declared and a landing accomplished at the nearest suitable landing area considering the severity of the emergency, weather conditions, field facilities, ambient lighting, and command guidance
What is the definition of Land as Soon as Practical?
Emergency conditions are less urgent and, although the mission is to be terminated, the degree of the emergency is such that an immediate landing may not be necessary
What is the definition of a Suitable Landing Area?
A suitable landing area is a hard surface runway, taxiway, or under/overrun. Landing on an unprepared surface or ditching is not recommended
How do you confirm a Battery Bus Failure?
BAT BUS indicator as well as multiple failures of items on the Battery Bus with associated CWS annunciatiors illuminated (TRIM OFF, OIL PX, HYDR FL LOW, PMU STATUS). The most noticable failures will be the EADI, GPS, AEDD, and power off flags in the standby ADI, standby turn and slip indicator, and pressurization.
If Bat Bus annuncator illuminates without actual loss of battery bus what should you do?
Check CWS circuit breaker (battery bus panel front cockpit). If CWS Circuit breaker is open, DO NOT RESET, battery bus is functioning normally, land as soon as practical.
If you confirm a Battery Bus failure what should you do?
Descent below 10,000 Feet MSL - Initiate (As required)
Composite Switch on Unaffected Display - Push
BUS TIE Switch - Open
AUX BAT Switch - ON
BACKUP UHF - ON
AUDIO Switch - select ALTN (BOTH)
LANDING GEAR EMERGENCY EXTENTION - Execute Prior to Landing
Land as soon as Practical
What is the effect on configuration that a confirmed Battery Bus failure will have?
Emergency Hydraulic System will need to be used to lower gear and flaps. OBOGS will fail, cockpit will depressurize
If the red GEN annunciator illuminates, what should you check first?
The Starter Switch, if the Starter switch is not in NORM, the generator will not function. If the starter switch is in Manual, the generator will not function and the starter will drain battery in less than 10 minutes if left on.
What should you do in the event of a red GEN annunciator?
STARTER SWITCH - NORM (BOTH)
GEN SWITCH - ON (front or back)
GEN RESET SWITCH - DEPRESS AND HOLD FOR 1 SECOND MINIMUM
How do you confirm an inoperative generator?
DC Voltmeter below 25 Volts and Ammeter Discharging
If generator remains inoperative after gen reset is depressed, what should you do?

GEN SWITCH - OFF
BUS TIE switch - OPEN
BOS PUSH MAN switch - PRESS ON
Land as soon as practical
What does opening the bus tie switch do in the event of generator failure?
Reduces electrical load by shedding items on the generator bus, this will permit main battery operation for at least 30 minutes.
How do you confirm a generator bus inoperative?
GEN BUS annunciator illuminated along with CWS annunciators illuminated for items on generator bus (most prominent indicator EHSI failure)
If GEN BUS annunciator illuminates without associated indicators of actual generator bus failure, what should you do?
Check CWS circuit breaker on generator bus panel and if open, DO NOT RESET.
Land as soon as practical
