This picture shows a CTOL CV(F) with its aircraft in
transit, or "showing" formation, because some of them at the bow of the
ship are blocking the catapults! The angled flight deck can be seen clearly.
The big advantage of an angled flight deck is that if an aircraft crashes
upon landing it is unlikely that it will hit either the island structure or
another aircraft.
This picture shows a typical CTOL configuration for the
CVF. The catapults can clearly be seen at the bow of the ship. Two cats
will permit two aircraft to be sent up at a time. The problem with
catapults, however, is a relatively low launch rate because the catapults
have to be retracted and steam built up once more before launching again. The
arrester wires for a conventional landing are also visible at the stern of
the ship. A STOBAR option would retain these wires to assist in the
landing of the aircraft. This picture which shows an aircraft landing shows
the usefulness of the angled flight-deck, and both the CTOL and STOBAR
would have this option.
