this manipulation gives a velocity movement (three sensitivities), not a position movement.
When the bearing of the alidade is greater than the antenna travel, in 60° it returns to the lubber
line of the aircraft axis indicator and the scan continues; in 30° AIR-AIR the antenna reaches the
stop but the scan continues, the alidade then remains at the stop of the scope. In all cases the
antenna bearing remains readable on the IDN's narrow pointer (selector on "R").
The alidade is controlled in distance by the rotation of the handle around its vertical axis. It is
also a velocity movement (three sensitivities); anti-clockwise increases the distance, clockwise
decreases it. The movement of the alidade cannot exceed 35 NM.
In search phase the segment is vertical and indicates the mean scanning axis of the antenna. The
length of this segment delimits, in distance (3 km), the area where engagement is authorized.
NOTE: The length of the vertical segment is scale independent.
In pursuit phase (“PS" or "PC") the segment is horizontal and shifted by 2/3 of its length to the
left of the locked target.

Types of engagement
A.
Manual engagement
This is the operation that allows the radar to pass from autonomous search to automatic pursuit.
To execute this transfer, the pilot has a two-position lever on the radar stick:
-
upper position, pre-selection authorization (APS)
-
lower position, continuous pursuit authorization (APC)
1.
Preselection Authorization (APS)
The "PS" is a pursuit of discontinuous information. In this function, the radar pursues a target
while maintaining its sweep. It gathers information about the target thanks to a small slowdown
scanning at the echo level. The echo is taken into account if it is located in an area of: 3 km
distance and ± 70 mrd in bearing, centered on the vertical alidade.
The transit of the alidade to the horizontal confirms the radar lock-on in "PS".
Each time the antenna passes over the target, the antenna is recentred in distance and bearing.
In this function, scanning ± 60° in 1 line is imposed. The target square is present but undergoes
fluctuations due to the resetting carried out at each scan.
NOTE: The firing of electromagnetic missiles is not possible in "PS".
2.
Continuous pursuit authorization (APC)
The "PC" causes the program to stop, that is:
-
stop scanning with antenna pointing in the direction displayed with the radar stick
(positioning of the alidade)
-
short pulse emission
-
deletion of the distance markers for the whole time the program is stopped
The engagement on target echo is possible in an area of ±1500 m delimited by the length of the
alidade.
The lock-on authorization will take place 0.1 second later if the echo coincides in distance and
in direction with the alidade and if its level is sufficient.
