What to bring to the review
- Exact battery, host and relevant charger revisions
- Confirmed requirements, proposed targets and unresolved questions kept separate
- A responsible owner and evidence location for each decision
5 fields for reviewing UAV battery voltage sag against mission limits
Use a row with field number, requirement, responsible party, revision, evidence link and decision. Keep the original measurements or documents available to the authorized project team. Mark missing evidence as open; do not replace it with an estimated pass.
- 1. Event identity: link the load change to the mission phase and its duration.
- 2. Measurement boundary: distinguish pack-terminal voltage from voltage at the aircraft input.
- 3. Starting condition: record pack revision, condition, starting voltage and temperature basis.
- 4. Time-aligned trace: retain current, minimum voltage, duration and recovery on one time reference.
- 5. Host result: compare the trace with the documented aircraft operating limits and observed response.
Use the record to make a scoped decision
Use synchronized measurements to review where a voltage drop occurs. Compare like configurations and report the actual minimum with its duration; do not combine a current peak from one run with a voltage minimum from another. Agree acceptance limits with the aircraft and battery teams before interpreting the result.
Keep acceptance limits explicit
This is an evidence-review worksheet, not a flight-to-failure procedure or a universal safe-flight voltage. Do not bypass aircraft or pack protections.
Technical context and limits
TI describes measurement and verification in relation to battery characteristics and operating conditions. The proposed worksheet applies that need for an identified measurement context; it does not prescribe a universal application pass limit.
