Airbus Abnormal & Emerg. proc. chapt.4 says:
"for single failure, Vapp= Vref +App spd increment+wind correction
*if APP spd increment is >=20 kts : wind correction =0
*if APP spd increment is < 20 kts : wind correction= 1/3 HWC
In case we have no "App spd increment" due to a failure (ex.one splr fault..) and no HWC that day, our Vapp will be VLS? :bored:
In the procedure and Technique chapt. it is stated :
"Vapp= Vls + wind correction. The wind correction is 1/3 of the head wind component (excluding gust) limited to 5kts as a minimum and 15 kts as a maximum."
"During autoland or when A/THR is used, or in case of ice accretion or gusty crosswind greater then 20 kts, Vapp must not be lower than Vls + 5kts"
Is there something i miss, or in case we land with: no A/THR, no autoland, single failure with no Speed increment and no HWC, we should fly at VLowest Selectable?...just 1.23 Vstall 1g?? without A/THR perhaps?
Someone can help?:ugh: TKS
