FLIGHT CREW TRAINING MANUAL
Should the LOC deviate, the pilot will fly the bird in the direction of the LOC index, and when
re-established on the LOC, set the tail of the bird on the TRK index again. If there is further LOC deviation, a slight IRS drift should be suspected. The bird is computed out of IRS data. Thus, it may be affected by IRS data drift amongst other TRK. A typical TRK error at the end of the flight is 1 ° to 2 °.
The ILS course pointer and the TRK diamond are also displayed on PFD compass.
FINAL APPROACH
When 1/2 dot below the G/S, the pilot should initiate the interception of the G/S by smoothly flying the FPV down to the glide path angle. The bird almost sitting on the -5 ° pitch scale on PFD, provides a -3 ° flight path angle. Should the G/S deviate, the pilot will make small corrections in the direction of the deviation and when re-established on the G/S, reset the bird to the G/S angle.

PREFACE
Applicable to: ALL
This chapter deals with some characteristics of the Non Precision Approach (NPA). Recommendations mentioned Refer to NO-100 PREFACE.
NPA are defined as:
? VOR approach
? NDB approach
? LOC, LOC-BC approach
? R-NAV approach.
APPROACH STRATEGY
Applicable to: ALL
The overall strategy of NPA completion is to fly it "ILS alike" with the same mental image or representation and similar procedure. Instead of being referred to an ILS beam, the AP/FD guidance modes and associated monitoring data are referred to the FMS F-PLN consolidated by raw data. LOC only approach is the exception where LOC mode and localizer scale are to be used. This explains why the crew must ensure that the FMS data is correct, e.g. FMS accuracy, F-PLN (lateral and vertical) and proper leg sequencing.
The use of AP is recommended for all non-precision approaches as it reduces crew workload and facilitates monitoring the procedure and flight path.
LIMITATIONS
Applicable to: ALL
Lateral and vertical managed guidance (FINAL APP) can be used provided the following conditions are met:
? The approach is defined in the navigation database
? The approach has been crosschecked by the crew with the published procedure
