During Construction

AC 150/5370-2G DRAFT

Advanced ASOS October 17, 2016 AS

Steven Oetzell, Lead Airport Certification Safety Inspector, FAA

2Federal AviationAdministration

Principal Changes

• Open trenches are allowed within the Taxiway

Safety Area with specific restrictions.

• Enhanced guidance for temporary shortened

runways and displaced threshold.

• Closed Runways and Taxiways.

• Guidance for the use of temporary orange

construction signs.

• Airport Operations Area (AOA) definition

• Document (Advisory Circular) reformatted

3Federal AviationAdministration

Taxiway Straight Sections –

Open Trenches are not permitted while taxiway is open

within taxiway safety areas.

– Exceptions: (when it is impractical to cover open excavation)

– It is acceptable to open the taxiway with a non-

standard TSA subject to the following restrictions:1. Taxiing speed is limited to 10 mph.

2. Appropriate Issue NOTAMs are issued. advising taxiing pilots of hazard and

recommending reduced taxiing speeds on the taxiway.

3. Marking and lighting meeting the provisions of paragraphs 2.18 and 2.20 are

implemented.

4. Low profile lighted barricades are installed on pavement edges. If the

pavement is wider than needed to provide the required taxiway edge safety

margin (TESM), low barricades may be installed at the edge(s) of the

required TESM to limit aircraft wander.

5. If desired, appropriate orange construction signs are to be considered.

Closed Runways and Taxiways

For a multiple runway environment, if the lighted X on

a designated number will be located in the RSA of an

adjacent active runway, locate the lighted X farther

down the closed runway to clear the RSA of the active

runway. In addition, the closed runway numbers

located in the RSA

of an active runway

must be marked

with a flat yellow X.

7Federal AviationAdministration

Temporary Outboard

White Threshold Bars

and Yellow

Arrowheads

If it is not possible to

install threshold bars,

chevrons, and arrows

on the pavement,

install “temporary

outboard white

threshold bars and

yellow arrowheads

outside of runway

pavement.

8Federal AviationAdministration

Lighting and Visual NAVAIDs

• At towered airports certificated under Part 139, holding position

signs are required to be illuminated on open taxiways crossing

closed or inactive runways. If the holding position sign is

installed on the runway circuit for the closed runway, install a

jumper to the taxiway circuit to provide power to the holding

position sign for nighttime operations.

JO 7110.65W:

3-7-2 Taxi and Ground Movement Operations - Aircraft/vehicles must receive a clearance

for each runway their route crosses. An aircraft/vehicle must have crossed a previous runway

before another runway crossing clearance may be issued.

NOTE− A clearance is required for aircraft/vehicles to operate on any active, inactive, or

closed runway except for vehicles operating on closed runways in accordance with a Letter

of Agreement (LOA).

9Federal AviationAdministration

Temporary Orange Construction Signs

• Airport operator may choose to include them as additional

safety mitigation for a construction project.

• Applicable AC:

– 150/5345-44 Specification for Runway & Taxiway Signs

– 150/5340-18 Standards for Airport Sign Systems

– 150/5370-2 Operational Safety on Airports during Construction

• Engineering Brief No. 93 DRAFT

– Not internally lighted (retro-reflective only)

– Either ground mounted w/ frangible couplings or portable signs

secured to weighted, low profile construction barriers

– Material, Color, Legend and mounting are discussed

– Size and location are per 150/5340-18, Standards for Airport Signs

10Federal AviationAdministration

11Federal AviationAdministration

Airport Operations Area - AOA

• Definition: A portion of an airport, specified in the

airport security program, in which security measures

are carried out. This area includes aircraft movement

areas, aircraft parking areas, loading ramps, and safety

areas, and any adjacent areas (such as general

aviation areas) that are not separated by adequate

security systems, measures, or procedures. This area

does not include the secured area of the airport

terminal building.

12Federal AviationAdministration

Reminder

• Establish a Safety Culture: Everyone has a role in

operational safety on airports during construction: the airport

operator, the airport’s consultants, the construction contractor and

subcontractors, airport users, airport tenants, ARFF personnel, Air

Traffic personnel, including Technical Operations personnel, FAA

Airports Division personnel, and others

• 5370-2 helps to assess stakeholders roles

carefully:

– Airport Operator (18 items listed)

– Construction Contactor ( 10 items listed)

– Tenant ( 8 items listed)

13Federal AviationAdministration

Keep this in-mind:

• For on-airfield construction projects at 139

airports funded without participation with

AIP or PFC funds, the preparation of a CSPP

represents an acceptable method that the

certificate holder may use to meet Part 139

requirements during airfield construction

activity.
