prior to donning crew oxygen masks.
Crew and passenger oxygen masks are not approved for use above
40,000 feet cabin altitude. Prolonged operation of passenger masks
above 25,000 feet cabin altitude is not recommended.
Passenger masks are intended for use during an
emergency descent to an altitude not requiring supplemental
oxygen.
RUDDER BOOST
Rudder boost must be on for takeoff.
On aircraft 45-002 thru 45-169 not modified by SB 45-22-4, rudder boost
must be OFF when the yaw damper is on.
SPOILERS/AUTOSPOILERS/SPOILERONS
Spoilers:
Do not extend spoilers with flaps extended while airborne, except as
specified in EMERGENCY and/or ABNORMAL PROCEDURES in
Section III and Section IV, this manual.
Autospoilers:
Autospoilers must be armed for takeoff and landing, except, do not
arm autospoilers for training maneuvers where engine failure will be
simulated above V1 speed or for touch-and-go landings.
STARTER
The following cooling periods must be observed between consecutive
uses of the starter:
After Start Attempt Wait
1 1 minute
2 2 minutes
3 30 minutes

SYSTEM LIMITS (Cont)
THRUST REVERSERS
Thrust reverser system use is limited to ground operations on paved
surfaces and attempts to deploy shall not be made in flight.
Thrust reversers must not be used to back up the aircraft.
Thrust reverser circuit breakers must not be intentionally pulled while
in flight, except as specified in EMERGENCY and/or ABNORMAL
PROCEDURES in Section III and Section IV of this manual.
Thrust reversers must not be used for touch-and-go landings.
Maximum reverse thrust is usable at speeds down to 40 KIAS.
Thrust reversers must be limited to idle reverse when the engines are
operating in MANual mode.
TIRES
Tire Limiting Speed (Ground Speed)...........................................165 knots
The takeoff and landing speeds presented in this
manual will not exceed this limit.
YAW DAMPER
On aircraft 45-002 thru 45-169 not modified by SB 45-22-4, rudder boost
must be off prior to engaging yaw damper.
On aircraft 45-002 thru 45-225 not modified by SB 45-55-6, the yaw damper
must be engaged for all flight operations except takeoff and landing.
On aircraft 45-226 & subsequent and prior aircraft modified by SB 45-55-6,
yaw damper use is not required.

ENGINE OPERATING LIMITS
􀁮 Maximum oil pressure may be exceeded for cold temperature starts for short
durations.
􀁯 Engine preheat is recommended at temperatures below -28°C.
􀁰 Allow oil temperature to increase to 30°C prior to increasing thrust above idle. If cold
ambient conditions prevent oil temperature from obtaining 30°C, idle thrust may be
exceeded as required.
􀁱 If altitude is greater than 30,000 feet: Oil Temperature — 140°C.
If altitude is 30,000 feet or less: Oil Temperature — 127°C.
􀁲 Manual Mode or RMU — 917°C (amber), Limit — 942°C (red).
􀁳 The thrust setting tables, in Section V, may be more limiting than the values listed
here.
