Traffic Patterns

Objective

Upon completion of this lesson, the CFI candidate will demonstrate the ability to teach helicopter traffic patterns (ACS HI.VII.C) by explaining and demonstrating proper traffic pattern procedures at both towered and non-towered airports/heliports. The CFI candidate will teach traffic pattern entry, maintenance of proper altitude (±100 feet) and airspeed (±10 knots), wind correction techniques, collision avoidance, and common error recognition and correction. The candidate will emphasize the unique considerations for helicopter operations in the airport environment and proper integration with fixed-wing traffic.

Introduction to Helicopter Traffic Patterns

Traffic patterns provide standardized procedures that enhance safety and efficiency at airports and heliports. Unlike fixed-wing aircraft, helicopters have unique operational capabilities that require specific considerations when operating in the traffic pattern environment.

Towered Airport/Heliport Operations (HI.VII.C.K1)

At towered airports, helicopters must:

• Establish radio communication before entering the traffic pattern
• Follow ATC instructions for pattern entry, altitude, and sequencing
• Use standard helicopter approach angles (typically steeper than fixed-wing)
• Request specific helicopter procedures when appropriate
• Comply with any published helicopter routes or procedures

At towered heliports:

• Follow published arrival and departure procedures
• Coordinate with ground control for movement areas
• Understand heliport-specific restrictions and noise abatement procedures

Non-towered Airport/Heliport/Helipad Operations (HI.VII.C.K1)

At non-towered facilities, helicopters must:

• Monitor and announce on the appropriate frequency (CTAF)
• Self-announce position and intentions clearly
• Follow standard traffic pattern procedures unless safety dictates otherwise
• Be aware that other aircraft may not see or hear helicopter transmissions
• Use visual scanning as primary collision avoidance

Landing area operations require:

• Thorough reconnaissance of unfamiliar areas
• Assessment of obstacles, wind conditions, and approach/departure paths
• Coordination with any ground personnel or other aircraft

Traffic Pattern Configuration (HI.VII.C.K2)

Standard traffic pattern components:

• Departure leg: Straight-out climb from takeoff position
• Crosswind leg: 90-degree turn from departure heading
• Downwind leg: Parallel to landing runway/area, opposite direction
• Base leg: 90-degree turn toward landing area
• Final approach: Aligned with landing runway/area

Helicopter-specific considerations:

• Steeper approach and departure angles than fixed-wing aircraft
• Ability to make tighter turns with shorter pattern legs
• Flexibility to modify pattern based on wind and obstacle conditions
• Option to use non-standard patterns when operationally necessary

Right-of-Way Rules (HI.VII.C.K3)

Federal Aviation Regulations establish clear right-of-way priorities:

1. Aircraft in distress has right-of-way over all other aircraft
2. Aircraft on final approach has right-of-way over aircraft on base, downwind, or crosswind
3. When aircraft are on final approach simultaneously, the lower aircraft has right-of-way
4. Aircraft on base has right-of-way over aircraft on downwind or crosswind
5. Head-on approaches require both aircraft to alter course to the right

Helicopter-specific considerations:

• Helicopters should avoid impeding the flow of fixed-wing traffic
• Use of hover capabilities to maintain spacing or yield right-of-way
• Responsibility to see and avoid regardless of right-of-way rules

Weather and Airport Information Systems (HI.VII.C.K4)

Automated systems provide critical information:

• AWOS/ASOS: Current weather conditions including wind, visibility, ceiling
• ATIS: Airport information including runway in use, weather, NOTAMs
• Airport/Facility Directory: Permanent airport information and restrictions

Helicopters must consider:

• Wind direction and velocity for pattern planning
• Visibility requirements for VFR operations
• Density altitude effects on performance
• Current NOTAMs affecting helicopter operations

Risk Management

Collision Hazards (HI.VII.C.R1) The traffic pattern environment presents multiple collision risks:

• Converging traffic on final approach
• Aircraft departing while others are landing
• Faster aircraft overtaking slower aircraft
• Aircraft operating at different altitudes
• Non-radio equipped aircraft at non-towered airports

Distractions and Situational Awareness (HI.VII.C.R2) Common threats to situational awareness:

• Radio communication requirements
• Traffic scanning while maintaining aircraft control
• Navigation and wind correction calculations
• Task saturation during pattern operations
• Fixation on one task while losing awareness of others

Windshear and Wake Turbulence (HI.VII.C.R3) Environmental hazards include:

• Mechanical turbulence from buildings and terrain
• Wake turbulence from larger aircraft
• Windshear near buildings or terrain features
• Sudden wind changes affecting aircraft control
• Density altitude variations affecting performance

Common Errors (HI.VII.C.K5)

1. Altitude deviations: Flying too high or too low in the pattern
2. Poor wind correction: Allowing drift to affect ground track
3. Inadequate spacing: Flying too close to other traffic
4. Poor radio technique: Unclear or incomplete position reports
5. Loss of runway orientation: Becoming confused about runway/landing area alignment
6. Inappropriate pattern size: Making pattern too large or too small for conditions
7. Failure to scan for traffic: Inadequate visual scanning for collision avoidance
