1. Does a bare LCD temperature report qualify the complete aircraft-powered display?
Yes, if resolution is unchanged No; assess component credit and qualify the complete boundary Yes, if the panel survived +85 °C
2. What does DO-160G Category X record?
Compliance was not demonstrated The most severe category was passed The condition is automatically inapplicable
3. Which Section 5 minimum ramp rate corresponds to Category B?
2 °C/min 5 °C/min 10 °C/min
4. How long is an ideal −40 to +70 °C one-way transition at 5 °C/min?
11 minutes 22 minutes Two hours including stabilization
5. What does an unpowered +85 °C survival result establish?
Continuous readable operation at +85 °C The applicable survival evidence, subject to its criteria All temperature categories
6. Is 65,000 ft the universal DO-160G decompression endpoint?
Yes Only for touch displays No; the method and aircraft/customer allocation define the endpoint
7. What does Section 9 explosion proofness address?
Ignition in a flammable atmosphere The speed of every pressure decompression A universal display-glass impact test
8. Why is a static logo a weak functional monitor during EMC testing?
It consumes too much power It can conceal a frozen frame It invalidates every emissions measurement
9. What is missing from the claim Lightning Level 3?
Nothing for any cockpit installation Only the display diagonal Applicable waveforms/methods, configuration and installation allocation
10. After a touch-controller change, what is the best evidence approach?
Reuse every old report automatically Assess affected mechanisms and substantiate credit or retest Repeat only a room-temperature image check
11. Does laboratory qualification alone establish installed readability?
No; viewing geometry, lighting and installation must be verified Yes, if the panel is bright Yes, if every category letter is listed
12. Which contract deliverable best supports an independent review?
A single pass certificate Only the laboratory invoice Configuration, as-run records, data, anomalies/retests, report and qualification summary
