Built-in GPS with Simplified Waypoint NAV (for IC-A25N)
The simplified waypoint NAV guides you to a destination by using current position information from GPS (also GLONASS and SBAS). The waypoint NAV has two functions: Direct-To NAV and Flight Plan NAV. In the Direct-To NAV, the IC-A25N directly guides you to a specified waypoint. In the Flight Plan NAV, the transceiver guides you to a sequential series of waypoints. Up to 10 flight plans and 300 waypoints can be memorized in the IC-A25N. Position information imported from an Android/iOS device* can be used as a waypoint.
* RS-AERO1A/RS-AERO1I required.
Flight Plans with Android™ /iOS™ App (for IC-A25N)
Using the RS-AERO1A (Android) or RS-AERO1I (iOS) application, you can make flight plans on an Android/iOS device and import the plan into the IC-A25N via Bluetooth. The following four functions are available:
1. Create a flight plan
You can make flight plans on an Android/iOS device by using preprogrammed waypoints.
2. Set Direct-To NAV
You can select a point on the map and export it to the IC-A25N for Direct-To NAV.
3. Display flight plan information
A flight plan in the IC-A25N can be displayed on an Android/iOS device.
4. Display waypoint information
Preprogrammed waypoints can be exported to an Android/iOS device and plotted on an map application.
VOR Navigation Functions (for IC-A25N)
The CDI (Course Deviation Indicator) is detailed like a real VOR instrument, and displays any deviation from your course.
The OBS (Omni Bearing Selector) enables you to change course from the original flight plan.
The TO-FROM indicator shows the position relationship between your aircraft and the course selected by the OBS.
The ABSS (Automatic Bearing Set System) function enables you to set the current course as a new course in two simple steps.
Near Station Search Function (for IC-A25N)
The near station search function assists you in accessing nearby ground stations. The function searches for nearby stations using the station memories that have GPS position information. To use the near station search function, position data and frequencies of the ground stations must be programmed.
Class-Leading High Power RF Output
Output power is increased to approximately 6 W typical (PEP) and 1.8 W typical (carrier) compared to the IC-A24 (5/1.5 W (PEP/carrier)). This expands the communication coverage and enhances the safety of aircraft operation.
Often used functions are assigned to the keypad and you can directly access a desired function. The enlarged flat sheet keypad offers smooth and swift operation.
2.3 inch Large High Visibility LCD
The large and high visibility LCD provides user-friendly, graphic screens. The night mode option enables easy viewing in the dark. The operating frequency in large characters can be recognized at a glance.
"Flip-Flop" Channel Recall
The IC-A25N/C stores the last 10 channels used. You can easily recall those channels by using the directional keys or the channel knob on the top panel. This is convenient for switching between several channels, such as NAV and COM channels.
Built-in Bluetooth® for Hands-Free Operation (for IC-A25N)
A third-party wireless Bluetooth® headset, like a 3M™ Peltor™ WS™ 5*, provides convenient hands-free operation. Also, by using the optional VS-3 Bluetooth® headset, the side tone function can be used.
* Compatibility not guaranteed.
Intelligent Battery with Detailed Battery Status
The supplied BP-288, 2350 mAh (typical) intelligent battery pack, provides up to 10.5 hours* of operating time. You can check the condition of the battery pack in the battery status screen. It is very useful for optimum charging and battery health maintenance.

Ingress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.
Degrees of Solid Particle Protection – 1st Digit
|IP6x||No ingress of dust; complete protection against contact. (Dust tight)|
|IP5x||Protected from the amount of dust that would interfere with normal operation. (Dust protected)|
Degrees of Liquid Ingress Protection – 2nd Digit
|IPx8||Protected against continuous immersion in water.
Depth and duration specified by model.
|IPx7||Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes|
|IPx6||Protected against water projected by powerful jets from any direction.
100 L per minute by a powerful jets (12.5 mm) for 3 minutes.
|IPx5||Protected against water projected by jets from any direction.
12.5 L per minute by a nozzle (6.3 mm) for 3 minutes.
|IPx4||Protected against water splashed against the equipment from any direction|
