Aviation watches with a stopwatch Achs-1 on the dashboard
In aviation the time and other indicators are measured using aviation watches, chronometers, stopwatches, which operate on the principle of mechanical oscillations of the pendulum. The mechanism of such devices is using of consumption of certain stock of the mechanical energy contained in the spring. Popular options installed on the aircraft, are clock Achs-1, which include the usual Chrono time stopwatch and a mechanism taking into account the flight period.
Consider modifications designed for the following purposes:
- The display of the current time (hours/minutes/seconds).
- For a single commit in hours and minutes (modification Achs-1M Achs-1МН).
- Count down the flight time of the airplane, helicopter or other aircraft.
- Keep records of small time intervals in minutes and seconds.
Sekundarna scale model Achs-1 is designed for 60 minutes, the variations Achs-1M, and MN – 30 mins the Second hand is placed at the center, performs the role secondaires works in this mode only if the stopwatch is on.
Normal daily functioning without interruption indicator, and a device which determines the flight time and stopwatch have a separate control. On the front of the device is of the scale (3 pieces) and head-stick (2 PCs).
The purpose of the left handle
The left head, which is equipped with a watch of aviation, performs several functions:
- Used for winding.
- Designed to move the shooter main daily item.
- Used for the navigation start and the deactivation mechanism of flight time.
The maximum plant spring guaranteed to work for 72 hours. In order to achieve optimal accuracy, it is desirable to have a device every two days. Temporary flight mechanism is controlled by pressing the handle to the left, the first action is activated, the signal in the interval formed by the color red.
Pressing the head off the flight time. Arrows record the presence of the aircraft in the air, the scale notifies a red and white color. The next (third) pressing the arrow returns to the original position ("12") niche signal indicates white color.
Why the need for the right head?
Right hand aviation watch with stopwatch are regulated by starting and stopping of the circadian mechanism, stopwatch, as well as to return the minute and second hands to the initial position.
Cyclic operation of the stopwatch passes the full stage by means of three taps. At the first touch of the activation secundamano mechanism. A second click stops it, and the third returns the arrow to its original position.
Watch aircraft equipped with electrically heated with thermostatic control enabled temperature in the range of 20 degrees. The element is connected to the onboard network at a constant current. Recommended start temperature is below five degrees. Before the flight, check the watch, put on them an accurate time record.
To do this requires overcoming a second hand phase "12" scroll head to the right in a clockwise direction, stopping the move. Next you need the left hand to pull up to the stop by rotating it in a circle from right to left to set the exact time. After setting the current settings is produced, the left head return to its original position. To start the clock right handle crank from left to right.
After received clearance to take off, you must activate the mechanism of flight time, after landing – shut down it by pressing the left knob.
Aviation mechanical watches (ASF) have the following characteristics:
- Covering the dial and hands with white paint or reflective ground.
- The error of accuracy in day – ±20 sec.
- Duration of full winding – 72 hours.
- Recommended frequency podsevatkin every two days.
- Voltage tracing circuit (const. current) – 27 V.
- Resistance electric heating is 50 Ohms.
- Food built-in backlight – 5.5 V from a network of 400 Hz.
- Weight 650-750 grams, depending on model.
- Overall the magnitude of ASF-1 – 85*91,4 mm.
A description of the items
Aircraft on-Board clock consists of a kind of motor (winding springs), devices responsible for current time, stopwatch, flight period, and the regulator controls and electric podogrev with a thermal controller, built-in backlight (ASF-1МН).
Device current time is continuously available from the engine, and flight time and stopwatch is activated and deactivated offline. For viewing of readings designed dial with scales (3 EA.):
- For indications of the current time – the main (large) scale.
- Sector "flight Time" – for the fixation of flight time.
- Sector "H" – for measuring functions of a stopwatch.
The control clock is realized by means of two heads (pens).
Factory "Molniya" in Chelyabinsk produces a unique project – aviation wrist watch, which is a replica of the instrument of the ASF. Dial compact models completely copies the design of the original aircraft hours, equipped with appropriate scales, which give the ability to measure time intervals in hours, minutes and seconds.
The material for the casing is stainless steel. In the new line created two versions: with a special black PVD coating and uncoated. On the back cover you can apply individual image commemorative inscription, a wish, using the method of engraving.
This original gift will delight any person associated with aviation or just a lover of quality things. Wrist option most accurately resembles aviation clock mounted on almost all types of domestic aircraft.
After this overview of aviation hours, it can be noted that it is a reliable, unpretentious device that provides a maximum precision of the current time, the parameters of the flight period, with the stopwatch function. Due to the high quality indicators, consider the device and its modifications over many years are used in aviation.
Flight watch with stopwatch does not require special care, one winding is enough for three days, and a defroster ensures proper operation at any outside temperature. In the Internet you can find a lot of ads about selling/buying models Achs, while their price is quite high. Additionally the quality of the device and their popularity confirms the wrist is the copy that is in great demand and is exactly the same layout and design onboard power variation.
