3.4.4.3.1. Missed Approach
A miss ed approach procedu re is ass oc i ated with every approach procedure contained in the naviga-tion database. It is extracted from the NDB when the approach procedure is selected and activated.
Objectives that shall be understood:
1.
How to append the missed approach proce-dure to the active flight plan during a go-around (GA).
2.
How to reengage LNAV and if applicable, VNAV during the missed approach.
3.
How to compare the electronic missed approach to the printed missed approach (e.g., overfly waypoints, left or right turns, altitude constraints, holding pattern, etc).
4.
How to read ARINC 424 leg types associated with missed approach procedures (e.g., way-points that are presented on the FMS but not on the paper chart).
5.
How to use the altitude preselector properly during a missed approach.
6.
Implications of prematurely activating the missed approach procedure on the FMS (e.g., not entering approach mode, horizontal and vertical deviation scaling, transition to the missed approach prior to completing the approach, etc.).
3.4.4.4. Alternate Destination
The alternate destination and its associated flight plan provide contingency routing in cases where it is not possible to continue to the destination.
Objectives that shall be understood:
1.
How to enter, change, or remove an alternate destination for the active flight plan.
2.
How to activate the flight plan to the alternate destination.
3.4.5. Holding Patterns
Holding pat terns can be def ined by the pilot or ex tr acted from the navi gation dat abase with
NBAA Automated Flight Deck Training Guidelines
procedures. Once activated in the flight plan, the FMS can enter, fly and exit a holding pattern.
Objectives that shall be understood:
1.
How to define, modify, activate and verify a holding pattern in the active flight plan.
2.
FMS defaults for holding patterns (e.g., speed, leg time/distance, etc.).
3.
How to delete a holding pattern once it has been activated and placed into the active flight plan.
4.
How to exit a holding pattern once it is active (e.g., automatically during course reversal, manually selected, etc).
Objectives that should be understood:
1. System limitations with regard to activating and modifying a holding pattern (e.g., too close to the waypoint, modifications to the pattern while in the hold, unable to activate a holding pattern on a waypoint while it is being laterally sequenced, etc.).
3.4.6. Direct-To
Direct-to is the ability to proceed directly to a loca-tion from the current aircraft position.
Objectives that shall be understood:
1.
How to perform a lateral direct-to to way-points in the active flight plan.
2.
How to perform lateral direct-to to waypoints not in the active flight plan.
3.
If applicable, how to undo a lateral direct-to (i.e., direct-to recovery).
Objectives that should be understood:
1. The relationship in sequence/timing between performing a lateral direct-to and engaging LNAV (if not already engaged) to avoid unde-sired S-turns.
3.4.7. Position Sensors
Position sensors provide position and velocity infor-mation required by the FMS to navigate the aircraft.
Objectives that shall be understood:
1.
The types of sensors interfaced to the FMS.
2.
How to access, interpret and operate the CDU pages associated with the position sensors.
3.
How to remove or reselect a sensor from the navigation solution (if applicable).
4.
The blending or weighting logic of sensors used to compute the FMS position.
5.
Any phase of flight operating limitations for a sensor (e.g.,IRS is approved for sole means oceanic operations, but not for sole means approach operations).
