What this outcome means
The FAA sent the case back to the filer rather than issuing a determination. This is the most common non-clean outcome and usually means something has to change or be supplied before the study can finish — not that the project was refused.
The proposal, in the filer's words
"Construction of 30ft billboard which will be static on one side and digital on other. The billboard will not impact any protection surfaces based on internal reviews. The digital unit is designed with downward-facing LED diodes so visibility from the air is minimal even on close approach. In addition Formetco incorporates light mitigating technology including louvers (protective shields) which help control light dispersion both vertically and from side angles."
