I wasn't able to attach the screenshot, don't know why, the uploading stops at 90%, nevertheless this a normal landing distance table with reference distances and adjustments for conditions like the normal landing table, except the title is:
Normal Configuration Landing Distance
Flaps 15,
Only for use with air turn back - Flaps 15 Supplementary procedure.
And the supp procedure air turn back in FCOM states this:
Air turn back - flaps 15 landing
When needed to meet return to land dispatch requirements, do the following
Plan flaps 15 landing and a flap 1 go-around.
Use normal descent procedure except:
Set Vref 15 or Vref Ice
If any of the following conditions apply, set Vref Ice=Vref15+10kt:
Engine anti-ice will be used
Wing anti-ice has been used during flight
Icing conditions were encountered during the flight and landing temperature below 10C
Use normal landing procedure except:
Ground proximity flap inhibit switch _____________flap inhibit
Use normal landing procedure.
Use the normal go-around and missed approach procedure except:
Use flap 1 for the go-around.
Limit bank to 15 when airspeed is less than Vref15+15 or the minimum manouver speed whichever is lower.
End of the procedure.
Any idea?
