Then I apparently can´t quote the following from the
Arsenal Errata:
"If a character improves the ratings of all of the individual
components in a sensor package, the overall Sensor rating of
the vehicle should also be improved accordingly. For the purpose
of improvement, sensors that do not have a rating are
considered to be automatically upgraded, when all the remaining
sensors in a package are improved to a higher rating.�
So put in some toys for that poor autopilot. There is a minimum of four individual sensors (same errata), easy to satisfy with that kind of capacity. You wouldn´t want to keep the sensor suite stock anyway.
