NMCB Specific 107 Contingency Operations Fundamentals

Question 1

What are the five teams that make up the Airfield Damage Repair organization?

Answer 1

Damage Assessment Teams, Crater Repair Team, MOS Selection Team, Crater Support Team, Hauling Team.

Question 2

What are the two different types of damage assessment teams?

Answer 2

Airfield Damage Assessment Team, Facility Damage Assessment Team.

Question 3

What information does the DAT gather?

Answer 3

Damage Assessment Teams (DAT) must gather two types of Information: Location of pavement damage caused by bombs, cannon fire; etc., and UXO data. The UXO data should include information regarding type, location, and number.

Question 4

State the purpose of the Damage Assessment Teams (DAT) in reference to Airfield Damage Repair (ADR).

Answer 4

The damage assessment teams (DAT) determine and report the location, types, and numbers of unexploded ordnance, and the location, types, and quantity of airfield pavement damage to the survival recovery center (SRC).

Question 5

State the purpose of the Minimum Operating Strip (MOS) teams in reference to Airfield Damage Repair (ADR).

Answer 5

A qualified team from the SRC, known as the MOS selection team, uses the information collected by the DAT to select the MOS, which must be cleared and repaired in order to launch and recover aircraft.

Question 6

What is the MOS for fighter aircraft?

Answer 6

5000ft x 50ft

Question 7

What is the MOS for the C-130?

Answer 7

3500ft x 60ft

Question 8

What is the MOS for the C-17?

Answer 8

3500ft x 90ft

Question 9

Define “Spall” in reference to Airfield Damage Repair (ADR)

Answer 9

A spall is damage that does not penetrate through the pavement surface to the underlying layers. Spalls may be up to 5 ft in diameter.

Question 10

Define “Crater” in reference to Airfield Damage Repair (ADR).

Answer 10

Craters represent damage that penetrates through the pavement surface into the underlying base and sub-grade soil uplifting the surrounding pavement and ejecting soil, rock, and pavement debris around the impact area. Craters represent much more severe damage than spalls.

Question 11

What is the difference between a large crater and a small crater?

Answer 11

Large craters have an apparent diameter equal to or greater than 15 ft. Small craters have an apparent diameter less than 15 ft.

Question 12

What are the four methods used by the NMCBs for Airfield damage repair?

Answer 12

Folded Fiberglass Matting (FFM)
AM2 Aluminum Matting
Crushed Stone
Concrete

Question 13

Describe Folded Fiberglass Matting (FFM).

Answer 13

A standard FFM weighs about 3,000 lb and consists of nine fiberglass panels, each 6 ft wide by 30 ft long by 0.5 in. thick. Elastomer hinges 3 in. wide connect the panels. When folded, these mats are 6 ft wide by 30 ft long and 8 to 10 in. thick.

Question 14

Describe AM-2 Matting.

Answer 14

Once the mainstay of runway crater repairs, AM-2 has been mostly relegated to a secondary use for taxiway repairs and parking apron expansion. AM-2 mat is suitable as a runway surface only for fighter aircraft and C-130 operations, and then only if accomplished as a flush repair. AM-2 is not an approved runway surface for C-17, C-5, C-141, KC-10, and KC-135 operations. This limitation is due to the inadequate anchoring system, narrow patch (54 ft wide by 77.5 ft long), and susceptibility to jet blast from outboard engines.

Question 15

Describe how crushed stone is used to repair a crater.

Answer 15

Fill the crater with crushed stone material and compact, placing it in lifts approximately 6 to 7 in. thick. Overfill the crater by approximately 76 mm (3 in.) above the original pavement surface height. Compact each lift of crushed stone using a minimum of four passes of a 5-ton single-drum vibratory roller or two passes of a 10-ton vibratory roller.

Question 17

What is the purpose for maintaining operator logs for boiliers?

Answer 17

The main purpose of boiler operating logs is to record continuous data on boiler plant performance. Logs become a source of information for analyzing the operation of the boiler for maintenance and repair. The daily operating log sheets provide the basic information around which maintenance programs are developed

Question 18

Describe the Bailey Bridge.

Answer 18

The Bailey bridge is a through-type truss bridge, the roadway being carried between two main girders. The trusses in each girder are formed by 10-foot panels pinned end to end. In this respect, the Bailey bridge is often referred to as the “panel” or “truss” bridge.

In most cases, no heavy equipment is required to assemble or launch a Bailey bridge; only basic pioneer skills and equipment are needed.

It is highly mobile. All parts of the bridge can be transported to and from the bridge site by 5-ton dump trucks and trailers.

It is versatile. Standard parts can be used to assemble seven standard truss designs for efficient single spans up to 210 feet long

Question 19

Describe the Medium Girder Bridge (MGB).

Answer 19

The medium girder bridge (MGB) is lightweight, hand-built, bridging equipment it can be built in various configurations.

The MGB parts are fabricated from a specially developed zinc, magnesium, and aluminum alloy (DGFVE 232A). This enables a lightweight, high strength bridge to be built. All except three parts weigh less than 200 kg. Most parts can be handled easily by four soldiers. The three heavier parts, used in limited quantities are six-man loads.

Single-story bridges can be constructed by 9 to 17 soldiers. The normal building party for double-story bridges is 25 soldiers.
