Appendix F Risk Assessment Instructions and Forms
This worksheet provides a starting point to logically track the process of hazards and risks. It can be used to
document risk management steps taken during the planning, preparation, execution of test missions and tasks.
All flyers must address the hazards listed in the attached risk assessment as a minimum. Operators may reference
the Range Safety Questionnaire if appropriate.
1 and 3: Self-explanatory.
2. Date is the date the form is prepared.
4: Subtask relating to the mission or task in block1.
5: Hazards Identify hazards by reviewing factors for the mission or task. Additional factors include historical
lessons learned, experience, judgment, equipment characteristics and warnings, and environmental considerations.
UAV Flyers must address all hazards listed in the attached forms, but are not limited to just these hazards. Those
that are unique to that UAV must also be addressed.
6: Initial Risk Level Includes historical lessons learned; intuitive analyses, experience, judgment, equipment
characteristics and warnings; and environmental considerations. Determine initial risk for each hazard by applying
risk assessment matrix on Page 6. Enter the risk level for each hazard-L, M, H, EH.
7: Controls Develop one or more controls for each hazard that will either eliminate the hazard or reduce the risk
(probability and/or severity) of a hazardous incident. Specify who, what, where, why, when, and how for each
control. Enter controls. References to the range safety review questionnaire are appropriate.
8. How to Implement and Who will Implement: Example of how: SOP, Rehearsal, UAS Operating Instructions.
Example of who: Supervisor, AVO, Mission Commander
9.: Residual Risk Level Determine the residual risk for each hazard by applying the risk assessment matrix on Page
6-4). Enter the risk level for each hazard-L, M, H, EH.
10., 11., 12.: Self-explanatory.
13: Risk Assessment Review. Required when assessment applies to ongoing operations or activities.

DD FORM 2977 INSTRUCTIONS, JAN 2014
Instructions for Completing DD Form 2977, "Deliberate Risk Assessment Worksheet"
1. Mission/Task Description: Briefly describe the overall
Mission or Task for which the deliberate risk assessment
is being conducted.
10. Overall Risk After Controls are Implemented: Assign
an overall residual risk level. This is the highest residual
risk level (from block 9).
2. Date DD/MM/YYYY: Self Explanatory.
11. Supervision Plan and Recommended Course of Action:
Completed by preparer. Identify specific tasks and levels
of responsibility for supervisory personnel and provide the
decision authority with a recommend course of action for
approval or disapproval based upon the overall risk
assessment.
3. Prepared By: Information provided by the individual
conducting the deliberate risk assessment for the operation
or training .
Legend: UIC = Unit Identification Code; CIN = Course ID
Number; OPORD = operation order; DSN = defense
switched network; COMM = commercial
12. Approval/Disapproval of Mission/Task: Risk approval
authority approves or disapproves the mission or task based
on the overall risk assessment, including controls, residual
risk level, and supervision plan. Space provided for authority to
provide additional guidance; use continuation page if needed.
4. Sub-task/Sub-Step of Mission/Task: Briefly describe all
subtasks or substeps that warrant risk management.
13. Risk Assessment Review: Should be conducted on a
regular basis. Reviewers should have sufficient oversight of
the mission or activity and controls to provide valid input on
changes or adjustments needed. If the residual risk rises
above the level already approved, operations should cease
until the appropriate approval authority is contacted and
approves continued operations.
5. Hazard: Specify hazards related to the subtask in block 4.
6. Initial Risk Level: Determine probability and severity.
Using the risk assessment matrix (page 7), determine level
of risk for each hazard specified, probability, severity and
associated Risk Level; enter level into column.
14. Feedback and Lessons Learned: Provide specific input
on the effectiveness of risk controls and their contribution to
mission success or failure. Include recommendations for
new or revised controls, practicable solutions, or alternate
actions. Submit and brief valid lessons learned as necessary
to persons affected.
7. Control: Enter risk mitigation resources/controls identified
to abate or reduce risk relevant to the hazard identified in
block 5.
8. How to Implement / Who Will Implement: Briefly
describe the means of employment for each control
(i.e., OPORD, briefing, rehearsal) and the name of the
individual unit or office that has primary responsibility for
control implementation.
15. Additional Comments or Remarks: Preparer provides
additional comments, remarks, or information to support
the risk assessment. If block 15 is used as a continuation
of block 14, strike through the block number and title.
Additional Guidance: Block 4-9 continuance page may be
reproduced as necessary for processing of all subtasks/
substeps of the mission/task. If a complete page is not utilized,
write “NOTHING FOLLOWS” on the first unused row,
immediately after the final item assessed.
9. Residual Risk Level: After controls are implemented,
determine resulting probability, severity, and residual risk
level.
