# What is the guy in green showing to the F/A-18E pilot before catapult launch?

In the following frames, you can see a guy in green showing a panel-like device with numbers on it to the pilot of the Super-Hornet that is about to launch from the carrier USS John C. Stennis.

• What is this panel for?
• What information is the pilot given?
• Why just before takeoff and not while boarding/briefing?

Edit: I won't accept this question as a duplicate. It may contain the answer

Taxiing up to the catapult, a green shirt will hold up the weight board. If the weight on the board matches the weight on the weight chit, acknowledge ...

but the question isn't really about that part and quite "hidden".

• @fooot I assume you are saying that he is showing the set catapult force to the pilot for verification purposes? I read the linked answer but it does not address what is displayed on that box. – Ron Beyer Mar 29 '16 at 16:48
• In the accepted answer, a green shirt will hold up the weight board, which is what your pictures illustrate. – fooot Mar 29 '16 at 16:52
• @fooot, ah, got it. The "possible duplicate" really isn't a dupe, but it is definitely related and happens to contain the answer. – FreeMan Mar 29 '16 at 17:16
• If you're happy to consider Wikipedia as being accurate, and articles like this do tend to be since many people would correct and there is little motivation for others to mislead, then this article will help. – Simon Mar 29 '16 at 18:10
