START HERE — LEARN THE SYSTEM IN 4 SIMPLE STEPS

Follow the four lessons from left to right. Learn one core idea, operate it, then move to the next step.

Understand the Big Picture

See how pilot voice moves through the microphone, audio panel, radio, antenna and finally reaches ATC.

Operate the Radio

Select VHF 1, tune the correct frequency, press PTT and watch the transmit and receive routes.

See a Complete Flight

Choose the correct communication system during gate, pushback, taxi, takeoff, cruise, oceanic flight and landing.

Continue With More Learning Tools

Use these after the basics to understand signals, data links, internal communication, failures, individual components and test your knowledge.

AIRCRAFT INTERNAL COMMUNICATION

WHAT'S HAPPENING?

Choose an action.

MIC / HANDSET→ AUDIO SYSTEM→ INTERPHONE / PA AMP→ DESTINATION

FAULT INJECTION

Inject a failure and then restore communication using a valid backup path.

No active fault.

RESTORE COMMUNICATION

Inject a fault first.

WRONG FREQUENCY SCENARIO

Tower frequency is 118.500 MHz. Enter a frequency and attempt contact.

No attempt yet.

COMMUNICATION SYSTEM COMPARISON

System	Main Job	Signal Path	Typical Use
VHF	Voice / data	Mostly line-of-sight	Normal ATC communication
HF	Long-range voice / data	Long-range HF propagation	Remote / oceanic operations
SATCOM	Long-range voice / data	Aircraft → satellite → ground	Wide-area connectivity
ACARS	Operational digital messaging	VHF data / SATCOM / HF data	Weather, ETA, airline, maintenance
CPDLC	Pilot-controller text	Datalink	Structured ATC messages
SELCAL	Selective aircraft alert	Radio tone call	Long-range radio monitoring
Interphone	Internal communication	Aircraft audio system	Cockpit, cabin and ground crew
PA	Passenger announcements	Mic → PA amplifier → speakers	Cabin announcements
