201 - Basic AAS

when should you locate an aircraft?

As soon as possible as far away as possible

What do you do before a departing aircraft starts its takeoff roll?

• Confirm all ground traffic has been removed from the runway in use and RPA

• Advise departing and arriving aircraft of any aircraft traffic or obstacles on the runway or RPA

What must you inform pilots of if not already in a NOTAM?

• Rough, flooded, or slippery parts of the maneuvering area

• Obstructions or debris on or near the maneuvering area

• Unserviceability or malfunction of any aerodrome equipment

• Wildlife and bird activity

• Other pertinent conditions

Who can report hazardous aerodrome conditions?

Pilots or other reliable observers

What are the three ways to obtain information?

Visual; audible; communicative

What are the most important elements of scanning?

Concentrate, maintain interest in the task, scan properly

When might you see something outside a fist sized area?

• There is movement

• There is striking contrast around it

What are the steps of scanning a small area?

1. Establish the object you will be scanning for

2. Establish scanning line, range, and direction

3. Scanning from left to right, look for the aircraft in the air or the vehicle or pedestrian n the ground

4. If the object is not found during the first scan return to the starting position and scan the next line or the next area close to the one already scanned

5. When the area to be scanned is well determined, scanning from the ground up, instead of left to right, can be done repeating the same procedure in #4

AAS (Aerodrome Advisory Service)

The provision by an FSS of information pertinent to the arrival and departure phases of flight and for transit through an MF area

MF (Mandatory Frequency)

Very high frequency specified in the CAP, CFS, or CWAS for the use of radio-equipped aircraft operating within a Mandatory Frequency Area

Mandatory Frequency Area (MF Area)

An area established at selected uncontrolled aerodromes within which aircraft are required to comply with mandatory-frequency reporting procedures

(Advise that advisory service is being provided)

What may you do if unable to provide advisory service on the MF?

Use any other frequency on which a pilot calls

What must you do if providing advisory when unable to use the MF?

Inform pilot traffic information may be incomplete. Advise pilot to use the MF to broadcast mandatory reports and to maintain listening watch
