ASC-5A Altitude Alert Super Clock Overview

Clock

The ASC-5A is a fully functional, panel mounted aircraft clock. Choose between local time or Zulu Time, and between 12/24 formats. The Up Timers and Down Timers have programmable alarms that will alert you at custom intervals, which is perfect for checking waypoint status, remembering to switch tanks, or for any of the other tasks for which you need an intermittent reminder.

Non-Volatile Memory

With the ASC-5A installation, it is not necessary to keep the clock attached to battery power. Non-Volatile memory ensures the clock is always accurate, to the second, without having to keep the instrument constantly powered up.

Altitude

The ASC-5A is not only a world-class aviation clock, it is an altitude management system as well. The instrument displays both ATC Altitude (picked up in between the Encoder and Transponder), and Density Altitude. The Density Altitude is corrected for by barometric pressure (input by pilot) and an Outside Air Temperature probe, which comes standard with the ASC-5A. Pilots can program alarms that will alert when they’ve reached a programmed altitude. Then, a Deviation alarm will alert when the altitude deviates too far from the programmed Destination Altitude. These tools are perfect for reaching and maintaining ATC assigned altitudes, Minimum Decision Altitudes, or whatever cruise altitude you decide during a VFR flight.

IFR Capable

Because the clock is accurate to the second, the FAA considers the ASC-5A to meet the requirements for IFR flying.

Installation

The ASC-5A can be installed as a minor alteration, with a logbook entry. No certifications or field approvals are required!
