DO-160 vs. MIL-STD-704: The Engineer’s Cheat Sheet for Power Quality Requirements
Aircraft Power Requirement Tool
DO-160 Section 16 and MIL-STD-704 (Aircraft) Standard Comparison
| PARAMETER | REQUIREMENT |

The 16V Trap: Many 'COTS' (Commercial Off-The-Shelf) power modules are rated for 18V-36V. If you use these in a Category Z environment, they will shut down during Emergency Operation tests at 16V. At Inrush Technology, we specialize in 'Wide-Input' de-risking, ensuring your power stage remains stable down to 16V without triggering an over-current protection or thermal runaway.
| Performance Level | Operation at 16.0V DC | Example Systems |
|---|---|---|
| Level A | Full Performance. The equipment must operate exactly as specified without any deviation or degradation. | Primary Flight Controls, Critical Avionics, Engine FADEC. |
| Level B | Operational. Minor deviation is allowed (e.g., screen flicker or increased noise), but the system must remain functional. | Navigation, Communication Radios, Internal Lighting. |
| Level C | Survive & Restart. The equipment can shut down or fail, but it must automatically return to normal operation when power returns to 28V. | IFE (Entertainment), Galley Power, Non-Essential Sensors. |
