What It Evaluates

Test full-scale production equipment or a representative prototype in its intended mounting and bonding configuration. Equipment is normally unpowered; high-voltage testing identifies likely attachment points before category-specific high-current testing is applied.

Equipment Categories:

• 1A / 1B: First-return-stroke zones with low or high flash hang-on probability.
• 1C: Reduced first-return-stroke attachment areas.
• 2A / 2B: Swept subsequent-stroke zones with low or high flash hang-on probability.
• 3N: Zone 3 equipment with novel designs or limited service history.

When It Applies

Applicability depends on the airborne equipment installation, declared category, aircraft environment, and program requirements.
