VHF Communication System
VHF Communication System
A system used for short-range voice and data communication between aircraft and ground stations, or other aircraft, operating in the 118 MHz – 136.975 MHz frequency range.
VHF System Components
VHF System Components
Each system consists of a transceiver (for sending and receiving signals) and antenna(s) placed strategically on the aircraft.
Radio Management Panel (RMP)
Radio Management Panel (RMP)
The RMP is a control panel where you select frequencies for VHF and HF radio systems. It has an "active" frequency window and a"standby" window.

Study Notes
VHF Communication System
- VHF communication is used for short-distance voice and data comms with ground stations or other aircraft.
- The frequency range for aircraft comms is 118 MHz to 136.975 MHz.
VHF System Components
- Modern aircraft have three independent VHF systems (VHF 1, VHF 2, VHF 3).
- Components include: transceivers, antennas, ACARS, AMU, audio equipment.
- Each system has a transceiver and antenna located in different areas of the aircraft fuselage.
- The 3 antennas are installed at different locations on the aircraft fuselage.
VHF System Components Location
- VHF antennas are positioned at specific locations on the aircraft's exterior.
- VHF transceivers are housed within the aircraft's avionics compartment.
Radio Management Panel (RMP)
- The RMP is used to select frequencies for VHF and HF radio communication systems.
- It has two frequency windows: active and standby.
- The active window displays the current operating frequency for the selected system.
- The standby window shows the new frequency selected.
- Pressing the transfer button swaps the active and standby windows.
- All RMPs are synchronized and update each other in real-time.
System Operation
- To connect to a VHF ground station, verify the audio equipment selection and the selected VHF system in the RMP.
- The desired frequency is selected using the frequency selector knob.
- Before transmission, listen for ongoing communication on the selected frequency.
- Transmission is initiated by activating the PTT (push-to-talk) switches.
