Triggered lightning
Hi all. Quick question from the back seats to those who know if i may. I am a regular customer in the back of the choppers in the north sea with a reasonable aviation background and I should have been on a chopper inbound today.
Instead of course its another night of offshore food and the cancellation of several choppers today including mine was based on grounding due to triggered lightning.
I checked for historical lightning strikes this afternoon and found none and I also have an app that gives a CAPE index - aparently a risk of lightning based on convection, also negligable.
The only reasoning i could find was the metar for egpd this afternoon indicated cb or tcu.
Could anyone please enlighten me on the decision making behind grounding flights for this reason? I also wonder if its company specific thing as other companies were flying today.
I would like to share this info with others offshore as one bet just now is that this company had their xmas party today.
Thanks.
