Upon power-up the Sensor requires approximately 20 seconds to produce a useable
image. During this time period a video test pattern is displayed for approximately 5
seconds followed by the message “OK”. After approximately 20 seconds the display will
blank momentarily for a NUC cycle and a useable image then appears. The image
generated is a monochrome (i.e., black and white) image. The
hotter an object is the
whiter it appears on the display. This is known as “white hot” polarity.
The display should be adjusted for optimum brightness and contrast, and readjusted
only during relatively benign phases of flight or periods of low workload. The image
then should be cross checked in a manner similar to other cockpit displays, using short
dwell times and appropriate cockpit priorities.
To optimize the IR image the EVS system periodically recalibrates itself. The
recalibration process is known as “Non-Uniformity Correction” (NUC). NUC can be
observed on the display as a momentary image interruption with “CAL” displayed. The
shutter closes for approximately one second during the NUC process, which happens
every four minutes or when manually activated, if an appropriate switch is installed in
the cockpit.
