19 (MOS) Minimum Operating Strip MOS- The launch and recovery surface selected for repair is called the minimum operating strip (MOS). The MOS is the area from which aircraft actually takeoff and land.When a MOS is combined with access taxiways from aircraft staging areas such as shelters and parking ramps, the entire area becomes the minimum airfield operating surface (MAOS).

26 ADR FactorsAircraft Type and Load. Each aircraft has distinct characteristics (e.g., wing span, tire pressure, load capacity, braking mechanism.) Available Material. The type and quantity of material (e.g., backfill, crushed stone, fiberglass mat) available for a repair. Available Equipment. The type and quantity of CESE available for a repair. Time Constraints. The time allotted to accomplish the repairs before the first aircraft arrival or departure. Repair Crew Capability/Equipment/Manpower. The repair crew’s capacity for the task (e.g., experience, number of repair people, resource availability). Type of Damage Sustained
27 Airfield Damage ABFC P-36 RRR – Ref. Manual Crater: is damage that penetrates through the pavement surface into the underlying base and subgrade soil uplifting the surrounding pavement and ejecting soil, rock, and pavement debris around the impact area. Craters represent much more severe damage than spalls.Large craters: diameter equal to or greater than 4.57 m (15 ft). Small craters: diameter less than 4.57 m (15 ft).ABFC P-36 RRR – Ref. ManualSpall: is damage that does not penetrate through the pavement surface to the underlying layers. Spalls may be up to 1.52 m (5 ft) in diameter.

34 106 Contingency Operations PQS Question 106.2Describe the following methods of RRR/ADR:Folded Fiberglass MattingAM-2 aluminum mattingCrete mobile
35 Folded Fiberglass Matting This procedure is currently the primary MOS repair method. It involves the installation of an anchored FFM over a crater which was prepared with a layer of well-compacted crushed stone. Crater preparation is essentially identical to that used with the AM-2 matting system. Again, this is the principle method of ADR employed for MOS repairs.The FFM is air-transportable, can be moved easily by vehicles, can be positioned at greater distances from airfield pavement surfaces, and must be stored indoors out of the elements.
36 Fiberglass Reinforced Plastic FOD CoversFolded Fiberglass MattingTwo patches per kit¼” thick 6’ wide, 30’ long30’ x 54’ patch – bolted together 60’ x 54’ patchTow into positionAnchor Leading and Trailing edge onlyDo not store in direct sunlightCan be used as flush finishUsed primarily on runway and taxiway

38 AM-2 Aluminum MattingHand-assembled and anchored over the crater which was prepared with a layer of crushed stone. This repair surface is the most manpower intensive of the two primary ADR techniques
40 AM-2 Aluminum Matting Primarily used on taxiway and parking apron Package contains matting, tools and accessories to assemble 54’ x 72’ FOD cover5 boxes contains 9 bundles of AM MattingCan be towed from side to sideMust be centered on the taxiwayAM2 patch is 54’ x 77’Must be towed by two pieces of like equipmentAM2 Matting cannot be a flush repair
41 Crushed Stone Repair Clear debris from the crater perimeter. Determine the actual crater diameter versus the apparent crater diameter, i.e., the extent of crater pavement damage/upheaval.Remove the up-heaved pavement.Remove large objects 36” or larger and water from inside the crater, as required.Backfill the crater with ejecta, ballast rock, or clean fill.Backfilling the crater with crushed stone.Compaction of the crushed stone.
42 Crushed Stone RepairInstall a 12” layer of crushed stone over the backfill material.Compact the crushed stone material in lifts approx 6” thick.Compact each lift of crushed stone using a minimum of four initial passes of a single-drum vibratory rollerFinal compaction with 28 passesRoll done parallel to runwayFor every inch above runway surface 3’ taper required
44 Crete mobileThe trailer-mounted crete mobile carries the cement, sand, and coarse aggregates in divided bins on the unit.Sand and aggregates are proportioned accurately by weight or volume with cement mixture and water and mixed.The mixing process will proceed until the aggregate bins are empty.Material feed to project can be stopped and started at any point to allow finishing crews to continue at a steady pace.
45 PavementAsphalt Pavements. Anchoring in asphalt pavement requires a 9.5-inch bolt and polymer. A hole 10 inches deep and 1.5 inches in diameter is drilled at the center of each predrilled mat hole. A two-part resin polymer is mixed and poured into each hole to about 0.5 inch below the surface of the pavement. An anchor bushing and bolt are immediately placed into each hole and pressed firmly (standing on the bolt and bushing) against the mat. The polymer will harden in about three minutes. Unless extra people are available, there may not be time to drill all the holes before beginning to pour the polymer

51 Camp MaintenanceControl Inspections - A control inspection reviews all camp facilities to determine the maintenance required during a deployment to preserve or improve the condition of the camp structures and property.It is the foundation for the camp maintenance program and workload.A control inspection is conducted within the first 30 days of a deployment.
52 Camp MaintenanceAnnual Inspection Summary – The AIS report documents deficiencies in camp facilities.AIS reports are produced annually.Validating deficiencies and costs is important to justify the money to support the proper maintenance and repair of camp facilities.
53 Camp MaintenanceOperator Inspections –consist of examining and making minor adjustments.Are performed by the operator assigned to the equipment.Are part of the operator's day-to-day responsibilities.
54 Camp MaintenanceThese inspections occur before, during, and after operation of the equipment.Operator inspection of constantly used equipment is another form of PM.
55 Camp MaintenanceTrouble Desk attendant receives all customer trouble calls, enters this information into the trouble desk log and fills out emergency/service authorization forms.Trouble desk attendant makes sure that ESA forms are properly routed and that outstanding ESA’s are completed within the required deadlines.
56 106 Contingency Operations PQS Question 106.4Explain the purpose of maintaining operators logs for generators and boilers [ref. c]
57 Camp Maintenance Operators Log Daily operating logs are kept on some Equipment. The main purpose for using operating logs is to continuously record data on equipment performance
58 Ground Rods Ground Rods Grounding protects human life, the generator, and the distribution systemProvides a path for electrical current to earth
59 Generator ShelteringGenerator sheltering protects and prolongs the life of advance-base portable generatorsProtects the equipment from rain, wind, and other adverse conditionsGood for noise discipline during contingency operations
