Need help from you guys!!
The distance between the Rocks (when RADALT callout was triggered) & Blackrock is approx. 1250 metres. Time elapsed from RADALT callout being triggered & time of impact is 28 seconds. That equates to 44.64 mr/sec..160.71 KM/hr ...or 86.7Knots
Does this mean tailwind was 11kts ???
I have't been at the controls of an aeroplane since 1994. Forgotten most theory !!!
