Hi Greg
I am of the opinion that the knee height comment was depth of water outside plane
Thanks Richie
If the premise is that the water outside the plane was knee deep during Betty's reception and conditions were
calm then I think the plane moved from the night before.
Say knee deep is about 1.6 feet
Per
Time and Tide, during Betty's reception the tide was as low as -.6 meters (even lower but thats where the chart stops)
The night before the tide was +.75 meters, a difference of 1.35 meters or 4.4 feet from Betty's reception.
4.4 + 1.6 = 6' deep water the night before if the plane did not move.
The dry transmitter constraint is 2'-11 7/16". See fig 8.
I'm not saying your premise is wrong, only that if we accept the premise then the plane either moved or the conditions were not calm. My speculation above was that the water was knee deep outside the plane and it had moved from where it was the night before. See
