REVERSER COMMAND & REVERSER AIR/GND change due regulatory requirement

REVERSER LIMITED Replaces the NGs REVERSER

NG

REVERSER COMMAND - the reverse thrust lever is not in the down

-

REVERSER AIR/GRD the air/ground thrust reverser logic is failed

REVERSER LIMITED - A fault in the thrust reverser system limits reverse thrust. Thrust reverser will not deploy or reverse thrust will be

limited to idle if commanded.

Unchanged

L/R (WAI) VALVES and (ENGINE) COWL VALVES changed from blue to amber lights.

L/R WAI COWL

ENG ANTI-ICE lights added.

ENG ANTI-ICE - indicates the engine anti-ice system has been inhibited

-

COWL ANTI-ICE - indicates an overpressure condition downstream of the valve

-

COWL VALVE momentary - related cowl antiice valve is in transit or, steady cowl antiice valve position disagrees with

related ENGINE ANTIICE switch position, or extinguished related cowl antiice valve is closed (switch OFF), or open (switch

ON)

- -

Crew procedures remain the same, only light color is different

Crew Procedures - New read-and-do non-normal checklists

Landing Attitude Modifier

Two functions - -

Firstly o What - Increased drag to assist in glideslope capture (F15/30) at idle thrusto F15 30o How - Automatically increases spoiler deflection to increase drag to allow similar

glideslope capture from above capability as the NGo NG

Secondly o What - Improves clearance for the longer nose gear during flare/touchdown (F30/40)o / F30/40o How - Automatically and symmetrically adds spoiler deflection to reduce lift and increase

angle of attack from Vref+10 to Vref+ 20o Verf+10Verf+20

o Jammed or Restricted Flight Controls

EJLA uses the flight spoilers for small changes to the flight path

EJLA

ON CWS force sensors detect control column force & deploys the

spoilers to a preset position

Push increase descent rate -

Pull decreases the descent rate -

BOEING20

Maneuver Load Alleviation (MLA)

Function - -

Reduces wing and aft fuselage bending loads during certain maneuvers and

load factors

How - -

MLA retracts the extended speed brakes during maneuvers that result in

higher load factors at certain gross weights

MLA

Note - -

o The speed brake lever does not move during MLA activation

o MLA

o When the conditions for MLA are no longer present, the

speed brakes will return to the selected position

o MLA



2017

BOEING21

Emergency Decent Speedbrakes

o Reduced flight crew and passenger exposure to high cabin altitude

during a rapid depressurization

o

o Armed when the aircraft is above 30,000ft & CAW active

o 30000 CAW

o Activated by moving the speed brake lever to flight detent position

o

o Raises speed brakes to a higher than normal position, increasing

the rate of descent

o

o Deactivated when the spoilers are stowed or CAW is no longer

active

o CAW
