Frequently asked questions

Q: You're signing off an AOG avionics mod where a replacement GNSS antenna uses a slightly different radome dielectric constant. The lab report barely passes mask limits, but the last three VSWR sweeps drift upward. While searching "RTCA DO-229 antenna group delay variation acceptance with material change" you need to decide whether release to service is defensible under certification rules. What action aligns with the intent of the standard?

A: Pushing this to service risks latent position bias that only shows up after temperature soak, and that can invalidate approach protection surfaces. The standard exists to protect integrity over life, not just a single bench snapshot, so a material change that nudges group delay trend forces you to prove stability after environmental exposure rather than leaning on a one‑time pass.

Q: An MRO is selecting a replacement GNSS receiver front-end SAW filter after obsolescence. The aircraft operates mixed GPS/GLONASS. You're googling "select SAW filter bandwidth for GPS GLONASS aviation receiver" while the test data shows marginal adjacent-band rejection trending worse over three units. What's the safest selection call?

A: Chasing noise figure at the expense of band coverage leads to constellation dropouts and dispatch hits in mixed airspace. The right call trades a bit of loss for stability and qualification so adjacent-band rejection doesn't erode with temperature, keeping integrity margins intact over time.

Q: During a ramp check, RAIM availability drops right after engine start. One tech says it's EMI, another blames satellite geometry. You're searching "RAIM loss after engine start GNSS aircraft troubleshooting". What response stops you from masking the real cause?

A: Ignoring a bonding issue lets conducted noise chew into C/N0 and can snowball into approach failures. Checking the physical RF path first addresses a condition that changes with engine start, instead of hiding it with procedural workarounds.

Q: A WAAS-capable FMS update is pending. The new software tightens integrity monitoring, but your antenna mod has that marginal trend. While looking up "ICAO Annex 10 GNSS integrity monitoring antenna assumptions" you need to decide if the aircraft can fly LPV after the update.

A: Letting LPV continue without revalidation risks integrity flags tripping at the worst moment, driving missed approaches. The integrity model assumes stable antenna behavior, so limiting operations until that assumption is proven avoids operational surprises.
