Communications, Light Signals, and Runway Lighting Systems

Objective

Upon completion of this lesson, the CFI candidate will demonstrate the ability to teach communications, light signals, and runway lighting systems for helicopter operations. The candidate will effectively explain radio procedures, emergency communication protocols, and lighting systems while demonstrating proper instructional techniques. This lesson supports ACS task HI.VII.B and prepares the candidate to teach student pilots safe and effective communication practices in the airport environment.

Content

Radio Frequency Selection and Management

Teaching students how to obtain appropriate radio frequencies begins with understanding the hierarchy of information sources. The primary reference is the Chart Supplement (formerly A/FD), which provides comprehensive frequency listings for each airport. Sectional charts show basic frequencies, while approach plates contain detailed communication requirements for instrument procedures.

For helicopter operations, emphasize the importance of monitoring multiple frequencies when operating in complex airspace. Unlike fixed-wing aircraft that typically follow predictable traffic patterns, helicopters often operate at lower altitudes and may need to coordinate with ground control, tower, approach control, and company frequencies simultaneously.

Teaching tip: Use the analogy of a telephone directory - students must know where to look up the right “phone number” for each facility they need to contact.

Proper Radio Communication Procedures

Standard phraseology follows the “who, where, what” format. Students must understand that clear, concise communication prevents misunderstandings that could lead to incidents. The AIM provides the foundation for all radio procedures, but helicopter-specific considerations include:

• Position reporting relative to prominent landmarks rather than runway references
• Altitude requests in feet AGL when operating below pattern altitude
• Route descriptions using ground references familiar to controllers
• Company frequency coordination for commercial operations

Demonstrate the difference between standard and non-standard phraseology through examples. Standard: “Helicopter 123AB, two miles southeast of the hospital, 800 feet, inbound for landing.” Non-standard: “Hey tower, this is the red helicopter coming in from the south side.”

ATC Light Signal Recognition

Light signals serve as backup communication when radio contact is lost. Students must memorize the meanings and appropriate responses for both aircraft on the ground and in flight. Create memory aids to help students distinguish between similar signals:

• Steady green: “Go” (cleared for takeoff/landing)
• Flashing green: “Get ready” (return for landing/cleared to taxi)
• Steady red: “Stop” (stop/give way to other aircraft)
• Flashing red: “Get out” (taxi clear of runway/airport unsafe)
• Flashing white: “Get back” (return to starting point - ground only)
• Alternating red/green: “General warning” (exercise extreme caution)

Transponder Operations

Modern transponder systems require understanding of Mode A, C, and S capabilities. Teach the standard codes (1200 VFR, 7500 hijack, 7600 communication failure, 7700 emergency) and emphasize the importance of proper code entry and altitude reporting accuracy.

For helicopter operations, discuss the challenges of altitude encoding accuracy when operating at low altitudes and in confined areas where GPS altitude may differ significantly from pressure altitude.

Lost Communication Procedures

Communication failures fall into two categories: equipment failure and inability to establish contact. Teach students to troubleshoot systematically:

1. Check volume and squelch settings
2. Verify correct frequency
3. Check microphone and headset connections
4. Try backup radio if available
5. Use light signals or other aircraft as relay

In controlled airspace, emphasize the importance of continuing flight according to the last received clearance or as filed. For VFR flights, squawk 7600 and land at the nearest suitable airport.

Equipment Issues and Communication Failures

Common equipment problems include:

• Microphone button stuck (stuck mic)
• Headset failures causing inability to hear transmissions
• Electrical failures affecting radio power
• Antenna damage from rotor wash or ground contact
• GPS interference affecting transponder altitude reporting

Teach students to carry backup communication devices and develop standard procedures for equipment failures. For commercial operations, emphasize company communication requirements and backup procedures.

Radar Assistance Services

ATC radar services include traffic advisories, safety alerts, and navigation assistance. Students must understand how to request services and the limitations of radar coverage, particularly at low altitudes where helicopters typically operate.

Teach the difference between radar contact and radar services. Radar contact means ATC can see your transponder return; radar services mean ATC is actively providing traffic advisories or navigation assistance.

Runway Status Lighting Systems

Modern airports employ various lighting systems to enhance safety:

• Runway Status Lights (RWSL) automatically illuminate when runways are occupied
• Takeoff Hold Lights (THL) at departure end
• Runway Entrance Lights (REL) at intersections and entrances
• Final Approach Runway Occupancy Signal (FAROS) for aircraft on approach

For helicopter operations, emphasize that these systems may not detect small helicopters in hover or slow taxi conditions. Pilots must maintain visual awareness and communicate position to ATC.

Common Errors and Risk Management

Communication errors often stem from:

• Using non-standard phraseology that confuses controllers
• Failure to read back altitude or heading assignments correctly
• Not monitoring appropriate frequencies for the phase of flight
• Hesitation to declare emergency when experiencing equipment problems

Risk management strategies include:

• Establishing clear communication protocols before flight
• Regular practice of emergency procedures
• Understanding when to escalate from “pan-pan” to “mayday” calls
• Maintaining situational awareness of backup communication options
