Landing Dist Proc for G+Y...How ?
Hi,
Whilst doing my conversion, I have come to a dead end on this calculation.
Could someone please clarify......and help me out.
HYD G+Y SUMMARY rev 43 PG 1.12, a landing wt of 66 T the given tabulated distance is 2550 m
Now going thro the normal calculation
Landing dist without autobrake dry the value is 910m (qrh 4.03)
Applicable ldg factors are (qrh 2.34)
1. G+Y = 2.8
2. Direct Law = 1.35*
3. Flaps<1 Slat >1, conf 3=1.95* (cannot locate a better combination) I know the Slat will be at posn 3 but there is no table to choose from ??? So maybe I am wrong here !
So the final ldg dist correction will be
1st scenario
910 x 2.8 x 1.95 = 4968m
2nd scenario
910 x 2.8 x 1.35 = 3439m
3rd scenario
910 x 2.8=2548m (pretty close to answer in summary table)
In case 1 & 2 its more than 2550 given in the summary.
can anyone tell me where I am going wrong please.
