Once the FAA has completed an aeronautical study, a determination
is issued regarding the impact to air navigation. One
of three responses is typically issued:
- Determination of No Hazard - The subject construction
did not exceed obstruction standards and marking/lighting
is not required.
- Determination of No Hazard with Conditions - The proposed
construction/alteration would be acceptable contingent
upon implementing mitigating measures such as the
marking and lighting of the structure.
- Determination of Hazard - The proposed construction/alteration
is determined to be a hazard to air navigation.
Please note that if at any time during the aeronautical
study, the proposed alteration is determined to be a hazard,
the study is halted with no further consideration and
an objectionable determination is issued.
