The objective is to be stabilized on the final descent path at VAPP in the landing configuration, at
1 000 ft above airfield elevation in instrument conditions, (or at 500 ft above airfield elevation in visual
conditions) -
тут, например, Аэрофлот убрал оговорку про 500 для Visual conditions, ужесточив требования.
In order to be stabilized, all of the following conditions must be verified before, or at this stabilization
height:
‐ The aircraft is on the correct lateral and vertical flight path
‐ The aircraft is in the desired landing configuration
‐ The thrust is stabilized, usually above idle, in order to maintain the target approach speed along
the desired final approach path
‐ There is no excessive flight parameter deviation.
GLIDE INTERCEPTION FROM ABOVE
The following procedure should only be applied when established on the localizer.
The flight crew
must react without delay to meet the stabilization criteria.
In order to get the best rate of descent when cleared by ATC and below the limiting speeds, the
flight crew should lower the landing gear and select CONF 2.
If above the glideslope:
APPR pb on FCU.............................................................................................................PRESS
FCU ALTITUDE............................................................................. SET ABOVE A/C ALTITUDE
V/S MODE......................................................................................................................SELECT
‐ Select V/S 1 500 ft/min initially. V/S in excess of 2 000 ft/min will result in the speed
increasing towards VFE.
‐ When reaching VFE, the AP maintains VFE and reduces the V/S without MODE REVERSION.
FINAL APPROACH
FLIGHT PARAMETERS.....................................................................................................MONITOR
‐ The PNF calls out if excessive deviation occurs:
• LOC: ½ dot
• GLIDE: ½ dot
Жирным выделил то, что высота ставится выше - следовательно, самолет будет снижаться без ограничения, если не захватит глиссаду, и потребуются дополнительные действия экипажа, если этого почему-то не произошло. Но это Airbus.
