A320 C.G Being Less Than 25% ...Question
Hello All....
in the A320 if the MAC T.O CG is less than 25% been indicated on the load sheet...
if max RTOW is required for that day...we must decrease the weight by 1000 kgs and increase V1,Vr and V2 by 1 knot.
if lower than MRTOW and Flex power is used ....we must decrease the flex by 2 degrees and increase V1,Vr and v2 by 1 knot.
in the QRH chapter 4.00 " in flight performance" page 4.01 "speeds"
on the bottom of the page it says "For C.G less than 25% add 2 knots to Vls and Vref"
so the question is ... for landing ...when the C.G is been known that it is less than 25% for T.O..do you have add 2 knots on Vapp ? ...that's what i understand when they say add 2 knots on Vls (by mental calculation not on mcdu because you can't change Vls) ..when you add vls + 2 that mean you have to increase the Vapp by 2 knots to stay 5 knots more than the Vls.Or do the FMGC take care of that and increase the Vls and Vrefs and Vapp?...one pilot told me that you add 2 knots on Vref incase of total Fac's loss so you won't have O,F,S speeds . ?
by the way..always when fully configured for landing ...i always notice that the C.G wheel is less than 25 % even if the load sheet shows that the Ldg c.g is more than 25 %.
thanks guys
