Expedite traffic
Provide flight information
Aid in search and rescue
Internal net recorder form
DA form 7461-R
Three qualities of a pathfinder ATC
Accuracy
Speed
Knowledge
What are the six communication techniques
Avoid a monotonous r pitch
Avoid a too slow or too rapid rate of speech
Avoid any display of emotion, nervousness, indecision, or excitement
Speak directly into the microphone
Speak in normal conversational tone
Speak with confidence
FM for Pathfinder operations
FM 3-21.38
FM for Army Air traffic control
FM 3-04.120
What are the 4 categories of pertinent flight information
Signal on call
Description of the landing sight
Wind speed and direction
Field elevation of the landing site (night ops only)
What piece of Pertinant flight information is only important for night operations
Elevation of the landing site
What is the definition of pertinant information
Information pertaining directly to your landing site
Definition of advisory information
Information that a pilot
Must know in order to avoid a hazardous situation
Categories of advisory information
Turbulence at or near site Obstacles hazards Artillery fire Enemy situation Weather Other A/C at or near site
What must be considered when reporting artillery fire as advisory information
Weapon system range
Maximum ordinate
Weapon location
Weapon direction
What are the 3 ATC cardinal rules for arriving or departing A/C
- Arriving A/C will not be given clearance to land until all proceeding A/C have taxied or flown forward of the designated landing point
- departing A/C will not be cleared for departure until all proceeding A/C have flown clear of the forward landing point
- never allow a sling load A/C to fly over personnel, equipment, or other A/C at any time
Definition of Pathfinder air traffic procedures
Procedures used by pathfinder element to promote safe and expeditious flow of air traffic in and around a tactical operation site
What are traffic patterns used for
Used to control aircraft around landing sites, drop zones, and pick up zones in order to ensure aircraft separation
Altitude of traffic patterns is dictated by what
Height of obstacles
Aircraft requirements
May be adjusted as situation dictates
What are the dimensions of a standard traffic pattern
Extends one statute mile in each direction from landing site center line
What are the 5 legs of the standard traffic pattern
The upwind leg The crosswind leg The downwind leg The base leg The final approach leg
What is the minimum pattern that can be flown
The final approach leg
What is the best traffic pattern for rotary wing a/c and why
Right traffic, because the pilot sits on the right
Where can rotary a/C enter a traffic pattern
Anywhere as long as it is consistent with safety requirements
Where can fixed wing A/C enter a traffic pattern
The first one third of any leg at a 45 degree angle
When can an A/C be cleared for strait in approach
Within 30 degrees of final approach leg
When is a closed traffic pattern used
Used when a/c doesn’t land in first approach
DZ operations when the a/c had to make more then one pass
What is the definition of a closed traffic pattern
When an a/c continues to orbit a landing site at a prescribed altitude
What is a modified traffic pattern
Any traffic pattern consisting of either two or three legs
What are the two methods of increasing distance between a/c
Extending one or more legs of the traffic pattern
The 360 degree turnout
When is a 360 degree turnout executed
To increase distance between faster and slower moving A/c
How long is a 360 degree turnout
Standard 2 minute turnout
When can an a/c not execute a 360 degree turnout
On the final approach leg
What is the approach most commonly encountered by the pathfinder and why
Circular, used when the pilot is unfamiliar with the landing site
If a situation arises after an A/C has been given clearance to land what command must be given to remedy the situation
Go Around command must be given
What are the 6 landing priorities in order
- a/C with inflight emergency
- Medevac Aircraft
- Coded Aircraft 1-8
- Flight of two or more a/c
- A/c with external load
- Single aircraft
GTA map markings
CCP and RP to OP site 6-8 kilometers
CCP and RP to control zone 3-5 kilometers
Fixed wing control zone 18 kilometer diameter
Rotary wing control zone 6 kilometer diameter
What are some Countermeasures used in an electronic warfare environment
Pro words indicating frequency switch
Transmission authentication procedures
Brevity codes
Required reports
