Limitations What is the maximum differential pressure for takeoff and landing?.125psi
Limitations During takeoff do not engage the autopilot until? 1000’ AGL
Limitations Max allowable headwind/tailwind/crosswind for auto land is: 25knots / 15knots / 25knots (15knots when RVR is less than 2400 RVR)
Limitations At what pressure altitude is the autopilot use below 100’RA prohibited? 8,000’
Limitations What are the minimum use of autopilot on approach: ILS coupled / Non precision approaches / Auto landings: 50’ AGL / 50’ below MDA / touchdown and rollout’
Limitations What flap settings are approved for auto landings? 25 and 30 degrees
Limitations What is the minimum oil for dispatch? ETOPS 18qts / Domestic 16qts
Limitations Maximum flap extension altitude 20,000’
Limitations Minimum altitude for speed brake deployment? 800’ or in flight with wing flaps 25 or 30 degrees.
Limitations The maximum allowable in-flight difference between captain and first office altitude displays for RVSM operations is: 200’
Limitations Maximum and minimum fuel temperature? Max 49C / Minimum at least 3C above the freezing point of the fuel being used or - 45C, whichever is higher.
Limitations With the main tanks less than full, what is the maximum permissible fuel quantity permitted in the center tank? 2000lbs.
Limitations What RNP values are the 757/767 certified?.15 RNP
Limitations May Jet B or JP4 fuel be utilized? No
Limitations When must the center tank fuel pumps be positioned OFF? Less than 5,000lbs in the center tank with the airplane readied for taxi/takeoff, and when center tank indicates less than 1,000lbs during climb cruise and descent.
Limitations May a fuel circuit breaker be reset? No.
Limitations What is the minimum hydraulic quantity prior to takeoff? Not below refill mark, RF.
Limitations Maximum tire groundspeed? 757/767 195kts / 205kts
Limitations Minimum crew oxygen bottle levels? Refer to the chart
Planning and Performance When do you need to compute new V- speeds? Weight adjustments exceeding 4440lbs, switching runways, or if the runway analysis is used
Planning and Performance Is the Flex temp in Fahrenheit or Celsius? Celsius
Planning and Performance What is the maximum thrust reduction allowed for takeoff? 25%
Planning and Performance Can you use a FLEX reduction if your anti- skid is inoperative, or one brake has been deactivated? No
Warning Systems During what phase of flight are the master warnings inhibited? Inhibited for fire only at nose strut extension, and ends at 20 seconds elapsed time or 400’RA whichever occurs first.
Warning Systems During what phase of flight are the master cautions inhibited? Inhibited takeoff roll at 80knots to 20 seconds after nose strut extension or 400’RA whichever occurs first.
Warning Systems When will the EMER LT unarmed light be illuminated? Anytime the switch is out of ARMED
Warning Systems Will the EMER lights come on with loss of Normal DC? Yes.
Warning Systems What is the required action for STATUS messages prior to departing the gate and starting engines? Contact maintenance for possible corrective action
Warning Systems What does the takeoff configuration warning test? Slat/flap takeoff configuration, stabilizer trim out of green band, spoilers armed, and/or, parking brake set
Warning Systems What is the effect on warnings/caution/advisory/status messages with the loss of an EICAS screen? Status messages will be inhibited, while other information is compacted onto one screen.
Warning Systems What will cause the activation of the landing configuration warning? When below 800’ and the gear not down and the throttles are retarded, or landing flaps selected.
Warning Systems When are cautions and warnings inhibited on approach? Below 200’RA
Warning Systems When are flight attendant calls inhibited? Below 800’RA
Warning Systems Can warning messages be removed and recalled with the cancel and recall buttons? No.
Warning Systems Can the landing configuration warning be canceled? Yes, by pressing the GND PROX/CONFIG OVRD switch.
Warning Systems During flight what causes the slats to automatically extend to the landing configuration? A stall warning causes the slats to extend to the landing position if the slats are in the Takeoff position. When the stall no longer exists the slats automatically retract.
Warning Systems How many stall warning systems are available? Two systems are available, both of which are energized in flight and deactivated on the ground.
Warning Systems When may the ground proximity switches be deactivated? Only for approved procedures where the use of flaps at less then normal flap position or landing gear up is specified.
Warning Systems What are the altitude parameters for the ground proximity system? Between 30’ and 2,450’RA
Warning Systems Will the GPWS provide a warning of flight toward vertically sheer terrain or of slow descents into unprepared terrain while in the landing configuration? No.
Warning Systems When is the predictive wind shear alert inhibited? Yes, during takeoff at airspeeds above 100kts, until reaching 50’AGL.
