I guess this this is one way to check the cowl latches without crawling around on one's knees.
One of the basic things with the cowling latches is that they are at the bottom centerline. And you really have to go down on your knees to be able to see if they are properly latched and locked. Murphy ...
No you don't.
Stand at the side of the engine near the anti-icing ring, facing aft.
Put your nearest hand against the cowling to steady yourself and then crouch down into a wicket keeper's crouch. Place your other hand on the ground and then you can lean your head down enough to see the cowl latches. Your knees don't touch the ground at all. You can also check the engine drain mast for leaks while you are there.
All done, no excuses. (You might at worst get a wet hand*, but better than an in-flight turn-back, or worse)
*dry it on your hi-vis.
