I am wondering what these markings (which I found both in the French Super Etendard and in the British Tornado) indicate? They may be something relevant for the maintenance crews.

Vertical stabiliser of a Super Etendard modernise, showing two types of stencils, one looks like a hook, the other a horizontal line with two bulges

The sine wave sign indicates an access panel for electronics. Two examples:

sbap.be; electronic comp. access

sbap.be; electrical bay access

The handle shape indicates a nearby anchor point for hoisting the plane.

In your photo, the forward facing protruding part is a forward radar warning antenna.

    $\begingroup$ Your answer could be improved by listing the picketing point (upper symbol) and describing what it is. $\endgroup$ Oct 18, 2021 at 22:49

    $\begingroup$ According to the diagram in the answer, the hook on a bar isn't a picketing point but a slinging/hoisting point. I don't know enough about maintenance to know if they're colloquially interchangeable. In any case, they're on civil aircraft too, not just military. $\endgroup$

  • $\begingroup$ @user: upper symbol was already described – see previous comment. Anyway, picketing point is simply tie-down point. $\endgroup$

    $\begingroup$ @TomW: Aircraft are serviced by more than one team, and each team services different types, e.g. fueling teams in an air force. This is easier than mistaking an access point and then opening them all :) $\endgroup$
