The left arrow or right arrow points to the current service provider region determined by the aircraft position data. Action on line key 6L returns the user to the ACARS PREFLT MENU page.
(a)
Automatic frequency management mode When line key 6R is pushed, the MU sets the automatic frequency management mode and blanks the star adjacent to line key 6R. The data frequency displayed on the second line of this page reflect the frequency determined by the MU automatic frequency management mode.
(b)
Manual mode The manual frequency management mode is entered by selecting a line key with a frequency defined. The star adjacent to the name of the frequency in use is blanked in order to indicate the last selection mode. While in Manual mode, if the selected frequency is different from the frequency determined by the aircraft position data, the MU displays the AUTO/MAN FREQ MISMATCH indication in the MCDU scratchpad. The left arrow and right arrow are displayed next to the line key selected by the automatic frequency management. While in manual mode, the arrow is not displayed if the MU does not receive aircraft position.
(2) ACARS OOOI STATUS pages (Ref. Fig. 015) The ACARS OOOI STATUS 1/3 page is accessed by pushing the line key 3L from the ACARS MISC page. There are three ACARS OOOI STATUS pages. On page 1/3, OOOI states which have not yet encountered time values are represented with white dashes. When the aircraft transitions to one of these states, the time is inserted as hhmm. The current state is indicated with an arrow in column 12 pointing to the appropriate state name.
NOTE : Only one arrow is displayed at any one time, all arrows are
____ depicted in the figure below to indicate their position.
Absence of the arrow indicates the current state is INIT.
FLT NO: This field displays the flight number.
RETURN: This field displays time when the aircraft returns just after
an OUT event.
OUT, OFF, ON, IN: These fields display the OUT, OFF, ON, IN times.
DEPT/DEST: This field displays the departure and destination

BLOCK: This field displays the aircraft time from the OUT event to the IN event. The block time is computed by subtracting the OUT time from the IN time. Whenever a new OUT or IN time is posted, this value is updated. FLIGHT: This field displays the time that aircraft has been airborne during one flight. The flight time is computed by subtracting the OFF time from the ON time. Whenever a new OFF or ON time is posted this value is updated. Pages 2/3 and 3/3 display the values of the inputs used to determine the OOOI state and the time of the last change in value. Page 3/3 displays the individual door discretes. The door status on page 2/3 represents the output of the door logic. Door status is displayed in data field "AAAAAA". When one of the doors is open, then the OPEN indication is displayed, and when all the doors are closed then the CLOSED indication is displayed. Slide status is displayed in data field "BBBBBB". When the slide is armed, then ARMED is displayed, and when the slide is not armed, then UNARMD is displayed. Parking brake status is displayed in data field "CCC". When the parking brake is set, then the SET indication is displayed, and when the parking brake is released, then the REL indication is displayed. Aircraft movement status is displayed in data field "EEEEE". When the aircraft movement is detected, then the MOVE indication is displayed, and when no aircraft movement is detected, then the STABLE indication is displayed. The flight phase is displayed in data field "F". The current OOOI state is displayed in data field "GGGGGG", OUT, OFF, ON, IN, RET IN, INIT, and HOLD. Each entry has a corresponding time tag. Actuation of line key 6R (PRINT prompt) on any page will attempt to print only that page of the ACARS OOOI STATUS screen on the cockpit printer. Actuation of line key 6L (RETURN TO ACARS MENU prompt) returns the user to the ACARS PREFLT MENU page. 中國航空網 m.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320飛機維護手冊 AMM Communications 通訊1(117)
