How Much Is Manual
Documentation Costing Your TIA?

Adjust the inputs to match your actual flight test program. See your estimated documentation overhead and TIA discrepancy risk benchmarked against programs running on Epsilon3.

Program Inputs
Conforming Aircraft 4
Number of conforming test articles in active flight test campaign
Daily Test Points 18
Average test points executed per test day across all aircraft
Flight Test Team Size 42
Engineers, FTEs, safety pilots, and data analysts on program
Active Test Days / Month 14
Flying days per month across the program
Certification Stage
Current position in FAA Part 21 / AC 21.17-4 pathway
Current Documentation Method
How test execution and data are currently recorded
Doc Overhead / Month — engineer-hours on
manual record management
TIA Discrepancy Risk — probability of a gap
surfacing in TIA review
Rework Delay if Gap Found — weeks to reconstruct
and remediate record
Documentation Overhead — Benchmarks hrs / month

Active Risk Flags
— Version drift across aircraft records
— Retroactive data entry risk (>4hr lag)
— Cross-team sign-off gaps in TIA package
— Institutional knowledge loss exposure
— Certification stage mismatch with record quality
This is your program. When a documentation gap surfaces in a TIA review, the delay isn't administrative — it's a program-level event. Epsilon3 was built by aerospace operators who ran these campaigns. No deck. Just a conversation.
