Study Notes

Configurations

The flaps lever has 5 positions: 0, 1, 2, 3, and FULL.
Two configurations correspond to flaps lever position 1: CONF 1 or CONF 1 + F.
Selection details are in subsequent paragraphs.

Automatic Retraction System (ARS)

When CONF 1 + F is selected, auto retraction of flaps to 0 occurs at 200 kt (before VFE, which is 215 kt).

Flap Load Relief System (FLRS)

Only available in CONF 2, 3, or FULL.
When activated, the system retracts the flaps to the deflection corresponding to the next retracted lever position.
Auto retraction occurs when VFE is exceeded (VFE + 2.5 kt).
If speed is reduced below VFE (VFE - 2.5 kt), flaps return to their normal (selected) position.
In CONF 2, auto retraction results in CONF 1* (20° slats/8° flaps).
In CONF 3, auto retraction results in CONF 2* (23° slats/14° flaps).
These configurations can only be obtained by FLRS activation.

Notes

When FLAPS 1 is selected, VFE of CONF 1 or CONF 1 + F is displayed, depending on the actual configuration. In approach, VFE next is 205 kt (VFE of CONF 1*).
When FLAPS 2 is selected in approach, VFE of CONF 2 or CONF 1* is displayed, depending on the FLRS activation.
When FLAPS 3 is selected, only VFE of CONF 3 is displayed on PFD independently of FLRS activation.

FLRS Activation

During FLRS activation, the ECAM upper display shows a flashing "RELIEF" message.
If speed is increased by 4 kt above the VFE, corresponding to the actual flap/slat configuration, an overspeed warning appears on the ECAM.
