SECTION 6 – AUTOMATIC

FLIGHT CONTROL

6-13

To prevent immediate proﬁle re-capture, the following

must be satisﬁed:

• At least 10 seconds have passed since the non-path

transition was initiated

• Vertical deviation from the proﬁle has exceeded 250

feet, but is now less than 200 feet

Pressing the

VNV Key twice re-arms Vertical Path

Tracking for immediate proﬁle re-capture.

VNV Target Altitude Capture Mode (ALTV)

NOTE: Armed VNV Target Altitude and Selected

Altitude capture modes are mutually exclusive.

However, Selected Altitude Capture Mode is

armed implicitly (not annunciated) whenever

VNV Target Altitude Capture Mode is armed.

VNV Target Altitude Capture is analogous to Selected

Altitude Capture Mode and is armed automatically after

the VNV Key is pressed and the next VNV Target Altitude

is to be intercepted before the Selected Altitude. The

annunciation ‘ALTV’ indicates that the VNV Target Altitude

is to be captured. VNV Target Altitudes are shown in the

active ﬂight plan or vertical direct-to, and can be entered

manually or loaded from a database (see the Navigation

section for details). At the same time as “TOD within 1

minute” is annunciated in the Navigation Status Box, the

active VNV Target Altitude is displayed above the Vertical

Speed Indicator (see Figure 6-13) and the “Vertical Track”

aural annunciation is issued.

As the aircraft nears the VNV Target Altitude, the ﬂight

director automatically transitions to VNV Target Altitude

Capture Mode with Altitude Hold Mode armed. This

automatic transition is indicated by the green ‘ALTV’

annunciation ﬂashing for up to 10 seconds and the

appearance of the white ‘ALT” annunciation. The VNV

Target Altitude is shown as the Altitude Reference beside

the ‘ALTV’ annunciation and remains displayed above the

Vertical Speed Indicator. The Required Vertical Speed

Indication (RSVI) is removed once VNV Target Altitude

Capture Mode becomes active.

At 50 feet from the VNV Target Altitude, the ﬂight

director automatically transitions from VNV Target

Altitude Capture to Altitude Hold Mode and tracks the

level leg. As Altitude Hold Mode becomes active, the

white ‘ALT’ annunciation moves to the active vertical

mode ﬁeld and ﬂashes green for 10 seconds to indicate

the automatic transition. The ﬂight director automatically

arms Vertical Path Tracking, allowing upcoming descent

legs to be captured and subsequently tracked.

Altitude Reference (In

This Case, Equal To VNV

Altitude Target)

Figure 6-15 VNV Altitude Capture

Changing the VNV Target Altitude

NOTE: Pressing the CWS Button while in VNV

Target Altitude Capture Mode does not cancel

the mode.

Changing the current VNV Target Altitude while VNV

Target Altitude Capture Mode is active causes the ﬂight

director to revert to Pitch Hold Mode. Vertical Path

Tracking and the appropriate altitude capture mode are

armed in preparation to capture the new VNV Target

Altitude or the Selected Altitude, depending on which

altitude is to be intercepted ﬁrst.

VNV target altitudes can be changed while editing the

active ﬂight plan (see the Navigation section for details).
