Push MCT button on TRI and observe MCT LIM is displayed in Data Line 2.
PMS will continue to command single engine speeds and a complete 2 engine profile until engine failure has been confirmed by one of the following:
.
If above single engine maximum altitude, confirmation is automatic. As airplane decelerates and approaches driftdown speed, PMS automatically enters driftdown mode.
.
If below single engine maximum altitude, PMS will display PLAN CRZ page with CONFIRMED ENGINE FAILURE and 1 ENG FL XXX XXXMN X:XX, alternately flashing in Data Line 3. Pushing Line Select key 3 will engage engine out mode and will clear flashing display from Data Line
3.
Note: At or below single engine maximum altitude, all CLB, CRZ and DES
modes are available.
Above single engine maximum altitude, PMS can only be engaged
into DES OPT or DRIFTDOWN submodes or engine out.
After entering DRIFTDOWN, PMS will continue to command driftdown speed and TRI selected thrust until two engine operation is restored or one of the following occurs:
.
Arrival at single engine maximum altitude.
.
Arrival at armed altitude below single engine maximum altitude.
.
Start of descent profile to BOD.
A cross-point (X-PT*) cannot be created in this mode and all previously inserted cross-points are cancelled.

Driftdown Altitude / Distance Inquiry:
Note: The driftdown altitude / distance inquiry will allow entry of an altitude or distance in Data Line 3 of the DRIFTDOWN page, thus creating a new vertical event called ALT*, with its corresponding altitude / distance / time data.
Altitude / distance inquiry procedure is valid only between present position and the end of the driftdown profile.
Note: If inquiry is to a point beyond driftdown profile it will not be accepted by the PMS.
If an Altitude / Distance inquiry is desired:
Altitude Altitude Desired .......................................ENTER INTO SCRATCHPAD
Enter desired altitude into scratchpad using data entry keys.
Line Select Key 3 ..............................................................................PUSH
Push Line Select key 3 and observe data is now displayed on Data Line
3.
Note: Distance and time in Data Line 3 will decrease until desired altitude is reached, then Data Line 3 will change to display next vertical event.
Distance Distance Desired ......................................ENTER INTO SCRATCHPAD
Enter a / and the desired distance into scratchpad using data entry keys.
Line Select Key 3 ..............................................................................PUSH
Push Line Select key 3 and observe data is now displayed in Data Line 3.
Note: Altitude and time now correspond to desired distance. Distance and time also decrease until zero distance and time are reached. Altitude will vary slightly but will always be that projected to be reached in displayed distance and time.
Distance inquires are limited to 999 NM.
OPERATIONAL ADVISORIES
Note: CDU Operational Advisory Messages appear in scratchpad of CDU. CDU MESSAGE annunciator (located on main instrument panel) will illuminate when a CDU scratchpad message appears. Procedures for clearing these messages are listed in the following tables.
MESSAGE CONDITION(S) CLEARED BY REMARKS, NOTES
ENTER PLAN 1. ENGINE start before plan data entered. 1. GWT entry. 2. PLAN entry.
CHECK GWT 1. Entered GWT outside limits (88 – 151 KLB). 1. Entry of GWT within limits. 2. CLEAR key. 3. Selection of different display page. Will not accept GWT outside limits.
CHECK FUEL 1. Engine start before fuel weight entered. 2. Entered fuel outside limits (10 – 43 KLB). 1. Fuel weight entry. 2. CLEAR key. 3. Selection of different display page if due to entry. Fuel displays blanked.
MAX LAND WT? 1. Predicted GWT at BOD greater than 135 KLB. 1. Correction of previously entered planning data if in error. 2. Entry of additional planning data: alt, wind, and temp. 3. CLEAR key. Correction or entry of additional data may cause predicted BOD gross wt. To fall below max.
CHK BOD FUEL 1. Predicted fuel at BOD less than 5 KLB. 2. Preflight or distance to BOD less than 500 nautical miles. 1. Correction of previously entered data if in error. 2. Entry of additional planning data: alt and wind. 3. CLEAR key. Correction or entry of additional data may cause predicted BOD fuel to increase above minimum.
