3.16 COUNTERMEASURES
Description
The integrated countermeasure system is an ALE-40 capable of launching chaff and flares. It was
installed on Spanish (and later Moroccan) aircraft and is one of the principal differences between
the Spanish CE and the base C model.
It is possible to mount either 30 chaff or 15 flare charges per side (although in practice flares
were only mounted on the left side for safety reasons). Countermeasures can be launched on
single mode, multiple or on a specific program. The timing and number of countermeasures
released on each configuration is adjusted on the ground. The possible modes are:

Single: Only one countermeasure is released per side (if both sides are selected).

Multiple: Allows the launch of a certain number of cartridges in a pre-set interval. 1, 2,
3, 4, 6 or 8 cartridges with a time in-between of either 100, 200, 300 or 400 ms.

Program: Commands the repetition of the previous ‘Multiple’ launch a certain number
of times with an interval. In this case, 1, 2, 4, 8 or C times, with C being continuous until
the countermeasures run out. The possible times between repetitions are: 1, 2, 3, 4, 5,
8 or R, with R meaning a random time interval.
Countermeasures can be set in the Mission Editor.
Controls
- OFF-SGL-MULT-PRGRM selector: enables the pilot to select the working mode of the
system: off, single, multiple and program.
- Chaff-Both-Flare selector: Allows the pilot to select if the launch order is to be sent to
the flares, the chaff or both.
- Emergency Jettison (JTSN): Commands the sequential and rapid ejection of all the flares.
Indicators
- Countermeasure counters: 2 counters inform the pilot of the remaining number of chaff
and flares.
