I am reading a book (in french) published last week about Air France ( La face cachee d' AF , by F.Amedeo) where a large part is about the company's safety culture. On the chapters on the AF447 accident and on the subsequent AF445 incident, , some information is different that of the BEA preliminary reports , mainly the speed buffer both a/c had .
On the AF447 :
The data coming from the BEA report indicates weight 205t, weight/balance 37,8%, FL350, Mach .82 and Out Air temp -42C.
The book claims a/c wa at Mach .81 and that with 8.1 Vmax was .02 Mach above and Vs 0.3 mach below IAS.
On the AF 445;
Someone in AF mentioned weight 196 T, FL380 and mach .82 , that to be 700ft above optimum FL .
Can someone with access to a A330 charts confirm those values ?
( and what will be the speed buffer on both a/c with M .82 ?)
