Approach

 

 

The approach phase begins when flying over the (DECEL) waypoint.

If entering the initial approach area with HDG or Track, then the approach phase has to be entered manually on the MCDU. This is done by selecting the approach prompt on the relevant performance page and confirming the action.

Normally ATC will request specific speeds and headings, but a fully automatic approach should be possible by letting the FMGS guide the aircraft right up to the ILS intercept at an approach speed.

When cleared by ATC, select the APP push button on the FCU. This will arm the G/S and LOC A/P modes. At LOC and G/S capture the A/P will follow the ILS beam to the touchdown point. During that descent, careful monitor of the aircraft speed , ILS deviation and aircraft configuration needs to occur.

A good approach speed for this model is about 180 to 190 knots flap 1 at about 2500 ft above runway altitude.

This is then followed by :

approx 2000 ft radio altitude FCU speed of 170 knots flap 2

approx 1800 ft radio altitude FCU speed of 150 knots flap 3

approx 1500 ft radio altitude FCU speed of VAPP (145 knots) flap land

approx 1100 ft radio altitude Gear down.



These are not necessarily representative of an A330-200 or any other aircraft but are within the FMGS model so that the auto land phase may be demonstrated. Early stabilization of final landing speed and configuration is recommended.
 

 

 

      

 

Monitoring the Approach

 

Prior to LOC and G/S capture

Check that the FMA shows CAT II or CAT III for the intended ILS approach. This will be in white in the 5th FMA column

At 350 ft

Check that LAND is annunciated on the FMA

At 50 ft

Check that FLARE is annunciated on the FMA

At about 30ft

Check that IDLE is annunciated for the thrust mode on the FMA

And pull back the thrust levers to the idle position

At touch down

ROLL OUT mode engages.

At touch down

Disconnect the A/P when required
