In order to maintain HIRF protection, bonding checks between airframe and electrical components carrying voltages greater than 50 volts RMS or DC or main earth return should not exceed
- 5 ohm.
- 1 ohm.
- 3 ohm.
Explanation from PART66Online
For HIRF and lightning protection, bonding between the airframe and electrical components carrying more than 50 volts, or the main earth return, must be a primary low-resistance bond not exceeding 1 ohm. Higher values such as 3 or 5 ohms would allow excessive potential differences and compromise the protective bonding.
