between one hour and an half and one hour and three quarters. The standard configuration of the couple of F/
A‐18s was composed by two AIM‐9Xs on the wingtips for both the jets, two AIM‐120C on the rails, one of
which (left station) was replaced in the second aircraft by the AN/ASQ‐228 pod, used for targets' tracking.
Both the fighters carried a ventral tank with the "STBY 121.50" words in red, which was the emergency fre‐
quency in use. During a typical mission the two F/A‐18s, once reached the operation area, separate themselves
and begin to flight straight parallel and opposite routes so, flying in the opposite direction, they can cover with
the APG‐73 radar all airspace assigned and, if necessary, they can achieve the target by performing at most a
90° turn. The pilots are assisted during the CAP with the information's received by the troops operating on the
ground on radar stations, mobile radars and STINGER antimissile warning system. In case of an unauthorized
airplane would penetrate into the controlled airspace, the procedure was to approach the intruder to get vis‐
ual contact with it and to order to switch the VHF radio frequency into 121.50, where it would receive instruc‐
tions to fly it back into authorized areas or even to force it to land. In the extreme case, they can also use the
weapons to shot down the intruder, but the final decision was up to the Department of Defense's Chief.
Fortunately, this year there were no violation of the restricted airspace over Davos were recorded and thanks
to the great efficiency of the military personnel and to the well‐established safety procedures between the
Army and the local police forces the protection to the World Economic Forum ended successfully without any
sort of problem or incident. As underlined by Colonel Walter Schlegel, commander of the Graubünden can‐
tonal police "The collective use of police forces from all over Switzerland and the Army is a great example of
the concrete operation of the integrated network for safety of Switzerland".
