F-PLN SEQUENCING
In NAV Mode, the F-PLN will sequence automatically. HDG/TRK Mode, the F-PLN will only sequence automatically if the aircraft flies close to the programmed route. Correct F-PLN SEQUENCING is necessary to ensure that we programmed missed approach route is available in the event of a go-around. If under radar vectors and automatic waypoint sequencing does not occur, the F-PLN should be manually sequenced. This can be achieved by either using the DIR to RADIAL in function or by deleting the FROM WPT Repeatedly on the F-PLN page until the next likely WPT To be overflown is displayed as the to WPT on the ND however when established on an ILS or LOC approach, do not perform a DIR to as this will result in LOC reverting to Nav mode. in this case the APPR or LOC will have to be re-armed to re-establish on the approach.
USE OF A/THR
A/THR is Recommended for all approaches as it provides accurate speed control. If planning to use manual thrust A/THR should be disconnected by 1000 ft on the final approach.
The use of A/THR does not absolve the pilot from his responsibility to monitor its performance. If A/THR operation is not satisfactory, use manual thrust.
FCU ALTITUDE SETTING
When established on final approach, set the missed approach altitude on the FCU. This can be done at any time after G/S or FINAL APP mode engages. For a selected non-precision approach using FPA, the missed approach altitude must only be set when the aircraft is below the missed approach altitude and no further level segment is required. This will prevent an unwanted ALT capture on final approach do not set the MDA or DH on the FCU. Setting up MDA or DH on the FCU would result in an unwanted ALT* when approaching MDA or DH, Resulting in the approach becoming destabilised at a critical stage.
AP DISCONNECTION
When disconnection the AP for a manual landing, avoid the temptation to make unnecessary inputs on the sidestick.
