Screensaver for Android devices in the form of an analog aircraft clock resembling ACS, the famous Russian aircraft clock. Shows current system time. It has second hand for the clock and two timers - one is with hours and minutes and with an on/off/reset flag. This was used for registering the flight time. The other timer is with minutes and seconds and is used for measuring time intervals. Both function by double tapping the face of the timer. Double tapping elsewhere turns off the screensaver. The clock hands and marks turn greenish during the night like in the real clock. The clock face moves at regular intervals to avoid screen burning.
