(1) What is the distance between position at 02.00h and LKP?
(2) What is the distance between INTOL and LKP?
(3) Do we know when they passed INTOL? BEA (JUL-09,p.41) states 01.33h.
(4) What speed was reported at INTOL?
Sorry Denis, I missed your post. I cited the distance from memory without verifying it and from the BEA flightplan and positions (below), you are correct, speed between 0200-0210 was about 468 knots (not 473)
AF447 positions:
0210: 02°58'47"N 30°35'23"W (LKP)
0200: 01°48'00"N 31°08'59"W
0150: 00°38'23"N 31°45'36"W
0140: 00°29'23"S 32°22'11"W
0130: 01°38'59"S 32°58'47"W
0120: 02°49'11"S 33°36'35"W
0110: 04°01'11"S 34°14'24"W
0100: 05°12'35"S 34°52'11"W
So, you can make all your calculations from that.
