UH-1H: Digital Display of ALT in Radar Altimeter is not readable anymore (daylight)

[wernst]

Since last update 2.5.6.50321 the digital display of ALT in the radar altimeter is not readable at daylight anymore.

Even when zooming in the blue digits are very vague, extreme weak, clearly not usable at daylight. All INST brightness knobs have been set to MAX.
