Pitch attitude angle or glide slope angle?  Pitch depends a lot on the
aircraft, somewhere between 8-12° is typical.

I've read somewhere that the meatball/FLOLS glide slope on US carriers
is set to 4°.  But remember that the carrier is *moving*, so the
actual descent angle flown by the aircraft will be less, depending on
the relative velocity.  I strongly suspect that they recalibrate the
angle for different aircraft (or even different aircraft gross
weights), wind speeds and ship speeds.

Actually, a basic angle setting of 3.5 degrees is most commonly used, with 4
degrees used for higher wind-over-deck conditions (+35 knots).  This assumes
a typical jet approach speed of 130kts.  The basic angle is adjustable by the LSO.  
And yes, you are correct, the decreased closure rate causes the actual glideslope
angle to be less.

Now to my regularly scheduled lurking... ;-)
