Prevent a collision between aircraft operating in the system, and to provide a safe, orderly expeditious flow of traffic.
What is the primary purpose of ATC?
When separating two primary targets on an analog system, controllers must measure from these specific areas of the radar blips, ensuring they do not touch
What are the centers of the primary radar targets.
A/C ID, Clearance Limit, SID, Route, Altitude, Mach, Holding instructions, Any Special Information, Frequency and Beacon Code
What are Clearance Items 4-2-1
nder Paragraph 5-5-7, a terminal controller may discontinue standard radar separation and apply "passing or diverging" separation once two opposite-course aircraft have passed each other, or if crossing, their courses differ by at least this many degrees
What is 15 degrees.
Under Paragraph 4-3-1, this is the only word controllers should avoid using in clearances unless they are actually clearing an aircraft for departure or canceling a departure clearance
What is Takeoff
Under Paragraph 3-7-1, controllers are strictly prohibited from issuing these types of taxi instructions that depend upon the movement of an active arriving or departing aircraft
What are conditional instructions? (e.g., "Proceed on Runway 26 behind the landing Kingair")
When separating a standard formation flight from other aircraft using radar, a controller must add this specific distance to the standard radar separation minima
What is 1 Mile
Under Paragraph 4-2-1, this word must always immediately follow the name of the destination when the clearance limit being issued is a landing facility
What is Airport.
An approach controller may initiate a vector for a visual approach only if the reported ceiling at the airport of intended landing meets this minimum altitude threshold above the MVA or MIA.
What is at least 500 feet (with visibility of 3 miles or greater).
This process utilizes automation systems to alert controllers when two tracked targets are projected to violate minimum radar separation parameters within a specific look-ahead time window.
What is Conflict Alert (CA).
Direction of holding from fix/waypoint Holding Fix/waypoint Radial, course, bearing, track, etc. Leg length in miles if DME or RNAV to be used. Specify in minutes if pilot requests. Direction of turns only if left turns are to be made or pilot requests.
What are Holding Instructions? 4-6-4
If a pilot informs you that they have received a TCAS Resolution Advisory (RA) climb or descent.
What is do not attempt to adjust the aircraft's flight path (or do not issue clearances contrary to the RA).
Unlike a visual approach, this type of approach must be explicitly requested by the pilot, cannot be initiated by the controller, and requires at least 1 statute mile of ground visibility
What is a Contact Approach.
Under standard terminal rules, this is the most common minimum distance (in miles) required between two aircraft targets when they are close (within 40 miles) to the radar antenna
What is 3 miles
If a change in atmospheric pressure occurs, controllers use this specific altimeter setting reading as the dividing line to determine the lowest usable flight level at or above 18,000 feet MSL
What is 29.92 inches mercury (Hg)
