A25N

VHF Airband Handheld

Built-in GPS with Simplified Waypoint NAV

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.

Flight Plans with Android™ /iOS™ App

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:

Create a flight plan	You can make flight plans on an Android/iOS device by using preprogrammed waypoints.
Set Direct-To NAV	You can select a point on the map and export it to the IC-A25N for Direct-To NAV.
Display flight plan information	A flight plan in the IC-A25N can be displayed on an Android/iOS device.
Display waypoint information	Preprogrammed waypoints can be exported to an Android/iOS device and plotted on an map application.

VOR Navigation Functions

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

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.

Easy-to-Use Interface

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

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.

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.
