Flight-deck qualification
DO-160G environmental qualification evidence support for flight-deck equipment
This support reads a flight-deck unit's DO-160G environmental qualification evidence and confirms the test categories claimed match where and how the equipment is installed. It suits control panels, glareshield units, and other equipment mounted in the crew environment. A specialist checks the environmental qualification form against the installation assumptions, confirms each declared category has a test report behind it, and finds the sections claimed but not substantiated. You receive a standards map tied to the DO-160G sections, a gap list ordered for closure, and a route to resolve each open item before submittal.
When this review is needed
- A flight-deck unit is heading for authorization and its environmental qualification form needs checking against the installation.
- The equipment is moving to a different flight deck and the installation assumptions behind the categories have changed.
- An authority finding asks which DO-160G section a stated category comes from and whether a report backs it.
- A design change touched the enclosure or mounting and the affected categories need re-examination.
The problem
The DO-160G environmental qualification form is easy to fill in and hard to substantiate. Every category letter on that form implies a specific test conducted to a specific level, and a flight-deck unit's form often carries categories inherited from a template or a prior installation that no longer match where the equipment actually sits. A crew-station location has its own temperature, vibration, and lighting conditions, and a category chosen for a different bay can be understated for the real installation.
What gets reviewed
- The environmental qualification form checked line by line against the installation assumptions
- Each declared DO-160G category matched to a specific test report and level
- Temperature, vibration, and shock categories reconciled to the crew-station environment
- Lighting and readability conditions relevant to the flight-deck location
- Power input and electrical categories for the equipment as installed
- The link between the qualification evidence and the installation the STC or TSO assumes
What gets validated
- Every category on the environmental qualification form has a test report behind it at the stated level
- Declared temperature and altitude categories cover the crew-station operating envelope
- Vibration and shock categories match the mounting and location, not a generic assumption
- The installation assumptions in the evidence agree with the STC or TSO installation basis
- Any category carried from a prior installation is confirmed valid for the current one
Evidence normally required
- The DO-160G environmental qualification form for the flight-deck unit
- The test reports supporting each declared category
- The installation assumptions, including location and mounting in the flight deck
- The certification basis and the intended installation approval path
- Any prior authority findings on the equipment's qualification
Common discrepancies
- A category on the form with no test report at the level claimed
- A vibration category carried from a prior bay that understates the crew-station environment
- A temperature range narrower than the flight-deck operating envelope requires
- Installation assumptions in the evidence that do not match the current STC basis
What is at stake
A category claimed without a matching test report is a finding waiting to happen, and on flight-deck equipment the fix can mean a real test late in the program. Worse, an understated category that passes review can leave the equipment qualified below its actual installation environment, which surfaces as field problems rather than a paper finding. Reconciling the form to the installation before submittal avoids both.
Move from findings to resolution
Identify gaps against the means of compliance.
How the work runs
Read the form
Take the environmental qualification form line by line and note the category and level declared for each section.
Match to reports
Confirm each declared category has a test report behind it at the stated level.
Reconcile to installation
Check the categories against the actual flight-deck environment and mounting, not a template.
Order the gaps
Rank unsupported and understated categories by closure effort so any retest is scheduled before submittal.
What the buyer receives
- A standards map tying each declared category to its DO-160G section and test report
- A gap list ordered by closure effort, with any needed retest called out
- A closure sequence from each unsupported category to the evidence that resolves it
Who uses the output
- Certification leads confirming the qualification form is submittal-ready
- Hardware and test engineers scheduling any retest the gaps require
- Compliance managers tracking unsupported categories against the submittal date
How the work fits into the transaction or program
The mapping runs once environmental testing is nominally complete and before the qualification evidence goes to the authority. It reconciles the qualification form to the actual flight-deck installation, so understated or unsupported categories surface while a retest is still schedulable, and its output feeds the installation approval the form supports.
Start with a single asset
Confirm requirements trace through verification.
Jurisdiction-specific considerations
FAA and EASA both accept DO-160G as an environmental qualification standard, and both expect the declared categories to match the installation the approval covers. The mapping notes where the installation assumptions hold for one authority's basis but would need to be restated for the other.
Regulatory limits
This work maps the qualification evidence to the DO-160G sections and reconciles it to the installation. It does not approve the equipment, issue a TSO or STC, determine airworthiness, or replace the authority's acceptance of the qualification.
What this review does not cover
- Conducting or witnessing the environmental qualification tests
- Authoring the environmental qualification form or test plans
- Issuing an approval or compliance finding for the authority
Specific to this review
- The environmental qualification form is the single most over-claimed document in an avionics package, because a category letter is quick to write and slow to substantiate.
- A crew-station location can be a harsher vibration and thermal environment than an equipment bay, so categories inherited from a prior installation are often understated for the flight deck.
- An understated category that passes review is worse than a missing one, because it qualifies the unit below its real environment and shows up as field failures rather than a finding.

Frequently asked questions
The equipment was qualified for a different aircraft. Can we reuse that form?
Sometimes, but only after reconciling each category to the new flight-deck installation. Vibration, temperature, and mounting conditions differ by location, so a category valid for the prior aircraft can be understated here and needs confirming before it carries over.
