Landing Distance Calculation with no wind A320
Hello all,
let`s say you have an "emergency elec conf" on the A320. According QRH your delta Vref is 10, Flaps 3, and the landing distance factor is 3,15.
I would like to know the resulting approach correction with no wind and no ice accretion.
According the table in the QRH(80.14) the approach correction is the highest of :
5kts if A/THR is on and/or in case of ice accretion OR
1/3 Headwind
In case of "emergency elec" you have no A/THR and if you also have no wind, there should be no additional approach correction. Is this correct?
The other day I calculated this scenario in our landing distance tool on the flight deck. It calculated an approach correction of 5kts and an additional factor of 1.1 for the landing distance. Why?
Can someone help, please?
