Hi,

been asked a few questions by my team members and was struggling to answer.

The alpha :

1)what is it supposed to look like on the water ?
I came up with the drawing I found on seabreeze
(my french version of it)



2) Distance
then I got asked : 50 m minimum or maximum between A and B ?

3) and yesterday I recorded an alpha (the green one) that actually looks like one (on ka 72 & google earth)



Any explanations/ clues ? Thanks in advance

Sean
