FCTM Flashcards
Minimum maneuver speed (amber band)
the minimum maneuver speed is the slowest speed that provides full maneuver capability, 1.3g or 40° of bank (25° of bank and 15° overshoot) to stick shaker.
As airspeed is decreased below the top of the amber band, maneuver capability decreases. In 1g flight, the speed in the middle of the amber band provides adequate maneuver capability or 30° of bank (15° of bank and 15° overshoot). The speed at the bottom of the amber band (top of the red and black tape) corresponds to stick shaker activation for the current g load.
Reduced maneuver margin?
The term “reduced maneuver margin”, when used in reference to anti-ice systems, means that the stall warning logic adjusts stick shaker to a lower angle of attack. This results in a higher stick shaker speed and a higher minimum maneuver speed. Flap retraction and extension speeds are not affected by the use of anti-ice systems, therefore maneuver margin is reduced.
Maximum wind adjustment?
When making adjustments for winds, the maximum approach speed should not exceed VREF + 15 knots or landing flap placard speed minus 5 knots, whichever is lower
Wind adjustment with tailwind?
Do not apply wind additives for steady tailwinds or tailwind gusts. Set command speed at VREF + 5 knots (autothrottle connected or disconnected).
Define V2 and V2+15
V2 is the minimum takeoff safety speed and provides at least 30° bank capability (15° + 15° overshoot) for all takeoff flaps.
V2 + 15 knots provides 40° bank capability (25° + 15° overshoot) for all takeoff flaps.
FMC Route Verification Techniques
The crew should always compare:
- the filed flight plan with the airways and waypoints entered on the ROUTE pages
- the computer flight plan total distance and estimated fuel remaining with the FMC-calculated distance to destination and the calculated fuel remaining at destination on the PROGRESS page.
Rudder trim techniques
The primary technique uses rudder trim only to level the control wheel and is an acceptable and effective method for trimming the airplane. It is approximately equal to a minimum drag condition. This technique is usable for normal as well as many non-normal conditions.
Alternate:
trim the rudder in the direction corresponding to the down (low) side of the control wheel until the bank indicates level (no bank angle indicated on the bank pointer). Apply rudder trim incrementally, allowing the bank to stabilize after each trim input. Large trim inputs are more difficult to coordinate. The airplane is properly trimmed when the bank angle on the bank pointer indicates zero. If the airplane is properly rigged, the control wheel should indicate approximately level. The resultant control wheel condition indicates the true aileron (roll) trim of the airplane being used by the autopilot.
FMC Performance Predictions
FMC fuel predictions are based on a clean configuration at normal thrust settings. Fuel consumption may be significantly higher than predicted in other configurations. Fuel consumption can be significantly different than predicted when operating at a reduced thrust setting
Autothrottle Use
Autothrottle use is recommended during takeoff and climb in either automatic or manual flight. During all other phases of flight, autothrottle use is recommended only when the autopilot is engaged in CMD. During engine out operations, Boeing recommends disconnecting the autothrottle and keeping the throttle of the inoperative engine in the CLOSE position. This helps the crew recognize the inoperative engine and reduces the number of unanticipated thrust changes.
LVL CHG vs VSPEED
LVL CHG is the preferred mode for altitude changes of 1,000 feet or more. V/S is preferred if the altitude change is less than 1,000 feet. If unplanned speed or altitude restrictions are imposed during the arrival, the continued use of VNAV may induce an excessive workload. If this occurs, use LVL CHG or V/S as appropriate.
AFDS Mode Control Panel Faults
If an AFDS anomaly is observed where individual pilot-selected AFDS modes are not responding normally to MCP switch selections, attempt to correct the problem by disengaging the autopilot and selecting both flight director switches to OFF. This clears all engaged AFDS modes. When an autopilot is re-engaged or a flight director switch is selected ON, the AFDS default pitch and roll modes should engage. The desired AFDS pitch and roll modes may then be selectable.
Pilot Incapacitation
Failure of any crewmember to respond to a second request or a checklist response is cause for investigation.
Crew Action Upon Confirming Pilot Incapacitation:
- after ensuring the airplane is under control, engage the autopilot to reduce workload
- declare an emergency
- use the cabin crew (if available). When practical, try to restrain the incapacitated pilot and slide the seat to the full-aft position. The shoulder harness lock may be used to restrain the incapacitated pilot
- flight deck duties should be organized to prepare for landing
- consider using help from other pilots or crewmembers aboard the airplane.
Moderate to Heavy Rain, Hail, or Sleet recommendations
The airplane is designed to operate satisfactorily when maximum rates of precipitation are encountered. However, flight into moderate to heavy rain, hail, or sleet could adversely affect engine operations and should be avoided, whenever possible. If moderate to heavy rain, hail, or sleet is encountered, reducing airspeed can reduce overall precipitation intake.
The Supplementary Procedure recommends that the crew should consider starting the APU, if available, because it provides quick access to backup electrical and pneumatic sources.
Turbulent air penetration recommendations
During manual flight, maintain wings level and smoothly control attitude. Use the attitude indicator as the primary instrument. In extreme updrafts or downdrafts, large altitude changes may occur. Do not use sudden or large control inputs. After establishing the trim setting for penetration speed, do not change pitch trim. Allow altitude and airspeed to vary and maintain attitude.
Maneuver at bank angles below those normally used. Set thrust for penetration speed and avoid large thrust changes. Flap extension in an area of known turbulence should be delayed as long as possible because the airplane can withstand higher gust loads with the flaps up.
Taxi with anti skid inoperative
With antiskid inoperative, tire damage or blowouts can occur if moderate to heavy braking is used. With this condition, it is recommended that taxi speed be adjusted to allow for very light braking.
Takeoff Flap Setting
For takeoffs, when conditions permit, consider using larger flap settings to provide shorter takeoff distance. Larger flap settings also provide greater tail clearance.
Minimum tail clearance flaps 1, 5 & 10
33, 51, 58
Tail strike pitch attitude?
11 degrees
Light weight take off recommendation
At light weight and aft CG, use of reduced thrust and rolling takeoff technique is recommended whenever possible. The rudder becomes effective between 40 and 60 knots.
Crosswind Takeoff technique
Engine surge can occur with a strong crosswind or tailwind component if takeoff thrust is set before brake release. Therefore, the rolling takeoff procedure is strongly advised when crosswinds exceed 20 knots or tailwinds exceed 10 knots.
Gusty wind take off guidelines
The use of a higher takeoff thrust setting reduces the required runway length and minimizes the airplane exposure to gusty conditions during rotation, liftoff, and initial climb.
To increase tail clearance during strong crosswind conditions, consider using a higher VR if takeoff performance permits.
This can be done by:
- using improved climb takeoff performance
- increasing VR speed to the performance limited gross weight rotation speed, not to exceed actual gross weight VR + 20 knots. Set V speeds for the actual gross weight. Rotate at the adjusted (higher) rotation speed. This increased rotation speed results in an increased stall margin, and meets takeoff performance requirements.
Reduced take off thrust (atm)
Reduced takeoff thrust (ATM) may be used for takeoff on a wet runway if approved takeoff performance data for a wet runway is used. However, reduced takeoff thrust (ATM) is not permitted for takeoff on a runway contaminated with standing water, slush, snow, or ice.
At any time during takeoff, thrust levers may be advanced to the full rated takeoff thrust.
Difference between TO/GA below and above 800ft?
When the airplane is below 800 feet RA, full GA N1 can be determined by pushing a TO/GA switch a second time. This will set the reference N1 bugs for full GA thrust. When the airplane is above 800 feet RA, pushing a TO/GA switch advances the thrust levers to full GA thrust.
What is Improved Climb Performance Takeoff?
When not field length limited, an increased climb limit weight is achieved by using the excess field length to accelerate to higher takeoff and climb speeds. This improves the climb gradient, thereby raising the climb and obstacle limited weights. V1, VR and V2 are increased and must be obtained from dispatch or by airport analysis.
