Non-Normal Checklists, when we have problems with high lift devices and :
- engine anti-ice will be used during landing
- wing anti-ice has been used any time during the flight or
- icing condiions were encountered during the flight and the landing temperature is below 10 degrees Celsius
require to use VREF ICE = VREF 15 + 10.
I wonder if we use flap setting another than 15 and above conditions shall we use ICE additive to VREF?
Thanks in advance
