completed and signed by appropriate personnel before completing the field study. The SOI should include
A18.5.1. Siting recommendation--location, orientation, and height.
A18.5.2. Data comparisons and determinations made during field study.
A18.5.3. Reasons for deviations, if any, from siting requirements.
A18.5.4. Panoramic pictures, if available.
A18.5.5. Economic evaluations, if applicable.
A18.5.6. Major construction requirements to support communications-electronic (C-E) equipment, if
A18.5.7. Other special considerations.
A18.6. SOI Distribution. The SOI should be distributed to all signatories for programming the support
construction and the CE installation. Copies should be retained by the appropriate Base Civil Engineer,
Communications, and Airfield Operations Flight offices. Copies should be sent to the MAJCOM and
AFFSA/XR. After agreement to a siting recommendation, the host base submits the siting plan to the
appropriate MAJCOM for approval. A sample of SOI is shown on the following pages.
A18.7. Sample Statement Of Intent (SOI)
A18.7.1. This is a Statement of Intent (SOI) between HQ AFFSA/XR and (enter appropriate Wing)
as it pertains to the (enter date) Site Survey for the proposed new air traffic control tower at (enter
A18.7.2. The purpose of this SOI is to reserve the area required for this project, to note the major
allied support requirements needed for later installation of the project equipment, and to serve as a
source document for Project Book preparation.
A18.7.3. This survey considers (enter appropriate number) possible control tower locations:
A22.214.171.124. Site No. 1: (Verbally describe location).
A126.96.36.199. Site No. 2: (Verbally describe location).
A188.8.131.52. Site No. 3: (Verbally describe location).
A18.7.4. Site Numbers. (insert appropriate numbers) were rejected for the following reasons:
A184.108.40.206. Site No. _________: (Insert reasons for rejection).
A220.127.116.11. Site No. _________: (Insert reasons for rejection).
A18.7.5. Based on the results of this survey, it is recommended that Site Number ______ be
selected for the new control tower. The following rationale supports this recommendation: (Insert
A18.7.6. The control tower will be designed using the _____________________________ AFB
control tower as a guide. The height of the control tower will be (insert height in meters (feet)). See
attached sketch. This height is necessary to provide adequate visibility for taxiways/ runways and to
provide the minimum angle of 35 minutes for depth perception to the farthest aircraft traffic surface
on the airdrome.
