on the ground display difference between p and cp
50 ft from sea level to 5000, 60 feet from 5001 to 10000
generators
if a generator load exceeds 41% while on deck, advance thrust to a min of 32%
oil quantity
overland ops: 60% full (12 qts)
overwater ops: 60% full (12 qts) or 7 qts plus 1 qt per total flight hour. whichever is higher. Flights should plan to arrive with 7 qts or more for possible toga operation
engine starter duty cycle
2 minutes
N2
do not try to engage the starter if n2 is more than 55%
max to egt
950-965 c 3 minutes
950 c for 5 minutes
if exceeds 950 but is less than 965 for less than 3 minutes, flight may be continued. thrust should be reduced below 950c as soon a flight conditions permit it
engine failure after takeoff
max time for operating at 950c goes from 5 to 10 minutes
max cont egt
925c
max start egt
725c
max n1
- 7% 20 seconds

max n2
105%
min oil px
13psi
during negative g you can operate below 13 psi for 10 secs before shutdown is required
max oil temp
155c
140-155c 45 minutes
140c continuous
engine idle prior to shutdown
3 minutes
engine ignition
shall be set to continuous if flying thru heavy rain, hail or sleet. shall be set to FLT is heavy turb is encounterd
windshear takeoffs
reduced thrust takeoffs not recommended if winshear conditions exist.
eec in alternate
no reduced thrust or atm takeoffs, no autothrottle, no fmc n1, and both eecs have to be in alternate
reverse thrust
not to be used in flight or for backing
unsymmetrical maneuver
a maneuver that includes a simultaneous combination of lateral control and elevator inputs such that high roll rate (greater than 10 deg/sec) is coincident with a/c load factor greater than 1.0gs.

landing lights
limit landing light illumination to less than 5 minutes when not in flight. does not apply to led landing lights
look ahead terrain alerting
do not use within 15 nm of takeoff, approach, or landing at an airport not contained in the system.
