What is RTCA DO-160?
RTCA DO-160, often referred to as simply “DO-160,” is a certification standard set forth by the Radio Technical Commission for Aeronautics (RTCA). It defines environmental conditions and test procedures for airborne equipment, covering everything from temperature, vibration, and humidity to electrical interference and lightning resistance.
A practitioner’s look at DO-160 Section 4 for galley equipment: what it tests, a real documented oven overheat incident, the design trade-offs behind passing it, and where certification credit gets lost years later.
DO-160 Section 5 tests how fast equipment can handle temperature change, not just the extremes. Here’s why that distinction causes real durability failures in galley equipment.
DO-160 Section 6 humidity testing runs equipment through repeated heat and moisture cycles. Here’s what the categories require and why galley equipment is an unusual, higher-exposure case.
Section 7 covers two different things: everyday operational shocks and crash safety retention. For heavy galley equipment near evacuation paths, retention design carries real consequences.
Vibration is one of the most category-dense sections in DO-160. Here’s the real structure, the category-mismatch trap, and why it should drive galley mechanical design early.
Waterproofness is one of the highest-stakes sections for galley equipment, and a current Boeing 787 Airworthiness Directive shows exactly why category selection and defense-in-depth matter.
Fluids susceptibility may be the single most relevant DO-160 section for galley equipment, and a real Airworthiness Directive on a galley water heater shows exactly why the failure usually comes from the equipment’s own fluids.
Sand and dust testing matters for externally exposed equipment. Here’s what it covers, the real-world erosion it guards against, and why it’s usually minor for enclosed galley equipment.
Fungus resistance becomes a genuine consideration for equipment that runs warm and humid in service, which describes a lot of galley equipment.
