Safe Operations on Battle Damaged Airfield Pavements

1
Safe Operations on Battle Damaged Airfield
Pavements

• Prepared By
• APR Consultants, Inc.

2
Will This Happen?

• Airfields are Easy Targets of Prime Importance
  for the Enemy
• If You are to Win the War, You Must Have an Air
  Force Your Aircraft Must Continue to Operate

3
Introduction

• During Times of Armed Conflict, Damage to an
  Airbase is Likely
• Techniques to Repair these Damaged Pavements are
  Available
• However, Are the Repairs Going to be Suitable for
  Safe Aircraft Operations?

4
Who is APR Consultants, Inc.?

• APR Sells Products and Services Specialized in
  Assessing Airfield Pavement Smoothness
• The Auto Rod and Level Profiling Device (ARL)
• APRas Aircraft Simulation Software
• Primary Clients are Civil Airport and Airport
  Authorities

5
The Auto Rod and Level
The Auto Rod and Level Measures the Pavements
True Profile
6
Aircraft Simulation Software

• APRas RRR
• Can Predict the Aircrafts Response to a Pavement
  Profile
• Can Determine if the Aircrafts Response is
  Severe Enough to Cause Damage to Aircraft
• Can Locate Area of Roughness and Optimize the
  Repair Process

7
An Effective Combination

• The Auto Rod and Level and APRas RRR are
  Effective at Keeping Pavements Operational
• Measure the Runways Profile with ARL
• Assess the Pavements Ride Quality usingAPRas -
  RRR

8
Scenario of Pre-Attack Operation

• Measure Profiles of all Applicable Pavements
  Using the ARL.
• Measure Three Lines Centerline and 3 to 10
  Meters Left and Right of Centerline for
• All Runways
• All Taxiways
• All Aprons Large Enough to Support Aircraft
  Operations
• This Establishes the Airfield Pavement Baseline

9
Post Attack Procedures

• Assess Damage
• Remove Unexploded Ordinance
• Establish Minimum Operating Strip (MOS)
• Repair Damage within MOS
• USAF Goal Airfield Operational Within 4 Hours of
  Attack

10
Are Repairs Suitable for Operations.

• Aircraft are Very Sensitive to Pavement Roughness
• The Same Repair Profile May be Acceptable for One
  Location but Not in Another
• How Will You Know if the Repair is Acceptable or
  Not.

11
APRas - RRR Will Give You the Answers

• After Repairs are Made to MOS
• Measure Repaired Profiles with the ARL
• Import the New Profile Data into the Airfield
  Pavement Baseline
• Using APRas RRR, Conduct Aircraft Simulation to
  Determine if Repairs are Suitable On the Spot

12
Example of Aircraft Simulation
13
Pavement Repairs Made for Simulation

• Repairs Made for Simulation Were Made According
  to Existing Specifications
• AFR 93-10, Troop Construction and Engineering
  Support of the United States Air Force Overseas

Example of Repair Made using AFR 93-10

Aircraft Response in Detail
15
Optimize Repair Using APRas - RRR

• Identify how Aircraft Responded to Repair
• If Too Rough, Modify Repair to Acceptable Levels
• When Aircraft Response is Acceptable, Commence
  Operations

16
When Aircraft Response to Repairs are Unacceptable

• Available Options if Aircraft Response is
  Unacceptable
• Refine Repair Profile by Lengthening Ramps and
  Reducing Repairs Height
• Reduce the Aircrafts Weight to Minimize Aircraft
  Response
• Begin Takeoff Roll Beyond Point of Repair
  (Displaced Threshold)

17
Summary

• In War, Airfields Will Be Damaged
• Pavement Repairs are not One-Size-Fits-All
• Crews Must Design Repairs Differently to
  Accommodate the Aircrafts Response at Speed of
  Impact
• APRs Auto Rod and Level and APRas RRR Can
  Provide the Answers to These Problems
