Track 184, TAS 463kts, W/V240/148 equates to Hdg 199, G/S 364. At around 37N this would require moving your 22.15, 22.21, and 22.27 LOPs 6nm right of track. This would place the 22.25 LOP about 6.5nm closer the GPS position, the 22.21 LOP 6.5nm closer, and the 22.27 LOP 6.5nm further away. This is known in England as ‘Sods Law’. I'm sure you're aware that there is a Coriolis correction table at the back of each of Vols 1, 2, and 3 of HO249/AP3270? DaveP
