Automatic Flight

Question 1

Recall function of the Altitude Select Knob

Answer 1

Rotate – preselects altitude in altitude window. If PROF
is engaged, sets FMS limits for climb or descent

PULL (Level Change) – Airplane will climb or descend directly to selected altitude and ATS will go to climb
thrust or idle descent as required

PUSH – Airplane will hold current altitude

Question 2

Recall function of the V/S-FPA changeover button

Answer 2

PUSH – Selects either vertical speed in fpm or FPA (Flight Path Angle) in tenths of degrees

Question 3

Recall function of the PROF switch

Answer 3

PUSH – Engages FMS vertical profile guidance

The aircraft is in PROF if the FMA altitude mode (word) is magenta. The altitude number will be white or magenta, depending on whether it is a known FMS
altitude

Note: In flight, PROF can also be used to engage the Autothrottle System

Question 4

Recall function of the HDG/TRK changeover button

Answer 4

PUSH – Selects either heading or track in the display window and on the ND

Question 5

Recall function of the NAV switch

Answer 5

PUSH – Arms the FMS NAV capture mode or resumes FMS lateral control

Question 6

Recall function of the FMS SPD switch

Answer 6

PUSH – selects the armed FMS speed.
Display window will show dashes and the
FMA speed changes from white to magenta

FMS speed can be edited by preselecting an FCP speed and immediately pushing this switch. Pushing
the FMS SPD switch again will cancel this FMS speed edit and FMS speed will return to ECON on the speed tape. However, the speed edit is not removed from the MCDU PERF page, it is just no longer active. EDIT speeds can bemodified, but not cleared.

FMS speed is disengaged by pushing or pulling the IAS/MACH select knob or engaging go-around

Question 7

Recall function of the IAS/MACH changeover button

Answer 7

PUSH – Selects either IAS or MACH in the display window

Question 8

Recall function of the IAS/MACH select knob

Answer 8

Rotate – preselects an IAS or Mach speed in the display window
PULL – Airplane will hold speed selected in the window
PUSH – Airplane will maintain current speed and the display window displays that speed

Question 9

Recall function of the APPR/LAND switch

Answer 9

PUSH – Arms the APPR and LAND modes (a tuned ILS is required)

Question 10

Recall function of the AUTOFLIGHT Switch

Answer 10

PUSH – Engages ATS and one AP in the FD mode that has been selected. After AP engagement, each push alternates the AP between AP1 and AP2

Question 11

Recall function of the AFS OVRD switches

Answer 11

PUSH DOWN – Allows emergency disconnect of respective autopilot, autothrottle and yaw damper

Question 12

Recall how Mach Trim is provided by the Flight Control Computers

Answer 12

• Only operative when Autopilot is not engaged
• When Mach trim is active, the stabilizer automatically moves to compensate for pitch forces caused by Mach number
• If Mach trim becomes inoperative, it will automatically stop driving the stabilizer and an alert will be displayed

Question 13

With the autopilot engaged, recall how the Bank Angle Limit Selector limits bank

Answer 13

Rotate - Selects max bank angle in 5 degree increments
AUTO - Bank angle limits vary with speed. This selector
cannot override FMS bank angle limits to make them less restrictive. They can be selected to more restrictive. Limits are displayed on the top of the PFD attitude sphere
