Summary of Contents for Renschler CoMo AV

  • Page 1 CoMo AV Instruction Manual Your CoMo is one of the most versatile, well featured and easy to operate flight instrument systems. To provide you with the most straightforward access, the manual is divided into 8 chapters. For rapid access the first chapter gives the important instructions: keys, functions, settings, displays and menus.
  • Page 2 1 CoMo AV Rapid Access 1.1 The CoMo AV Keyboard For easy operation the Keys (Push- Buttons) are arranged in two groups: Function Group is on the right hand side of the instrument and the Adjustment Group is along the bottom.
  • Page 3 Functional Group The keys in this section offer direct access in flight. All Function buttons are located next to the corresponding display, making incorrect operation most unlikely. Altitude-Function-Button A brief push shifts to the next value (e.g. from "alt 1" to "alt 2"). Make a long push to enter the adjustment menu.

  • Page 12: Description Of The Functions

    2. Description of the Functions 2.1 Altimeter Briefly push Altitude-Function-Button to shift between three different altitude-indications. "alt 1" and "alt 2" can be individually adjusted. The third altitude "zero" sets the indication to 0, whenever this function is activated. "alt 2" is linked to QNH (air pressure). If you are within the alt 2 adjustment menu, the speed indication shows the QNH value corresponding to altitude.

  • Page 13: Main Menu Setting

    - Push the EXIT-Button repeatedly to leave the adjustment menu without changes. Hint: In case you want to change more altitude values, confirm input by pushing the Rotary-Button instead of the Altitude- Function-Button. This way you keep the adjustment menu active for further adjustments.

  • Page 14: Variometer

    2.2 Variometer The variometer calculates climb or descent rate by measuring air pressure differences. This value is almost instantaneously indicated on the Analog- Vario-Display, while the averaged rate of climb or descent (within a selected timespan) is shown in the Digital-Vario-Display. 2.2.1 Analog Variometer (direct vario) Currently the analog variometer is limited to a range of + / - 10 m/sec.

  • Page 15: Audio

    2.3 Audio The volume can be quickly adjusted in flight by the Acoustic- Function-Button. A brief push shifts from "loud" to "quiet" and further on to "off". The present state of the acoustic is shown in the corresponding loud display. 2.3.1 Volume levels "loud"...

  • Page 16: Flight Profile

    2.4 Flight Profile The new feature of freely adjustable profiles is very useful for varying flying tasks. For any demand (thermalling, cross-country, acro) there is a configuration you can pre-adjust and recall when needed. Hint: In delivery-state only profile 1 is active! To use further profiles, they have to be activated in the menu.

  • Page 17: Time, Date And Stopwatch

    2.5 Time, Date and Stopwatch Time and Stopwatch On page 1 time appears on the left and a stopwatch on the right. The stopwatch can be started manually by a long push on the Logger-Button, or starts automatically when the instrument passes through a change in altitude beyond 15 m.

  • Page 18: Logbook Manual Start

    2.6.2 Logbook Manual Start The logbook can also be started manually by a long push on the Logger-Button. The indication skips automatically to the time/stopwatch-page and the stopwatch starts running. time and flight duration Stopwatch running, flight will be recorded Logbook Evaluation The Logbook is accessible through the menu (long push on the Rotary-Button, then turn until the display reads "Logbook").

  • Page 19: Battery Condition

    2.7 Battery Condition The CoMo AV uses two AA-cells. The battery-state-indication and battery-info-page keeps you informed about the battery condition. The battery-info-page shows on the left the actual voltage. New cells should provide at least 3.2 V. If voltage falls short of 2.2 V, cells should be changed.

  • Page 20: Battery Replacement

    You can estimate the remaining operation-time by watching the battery-time-counter. A new set of batteries should be good for about 700 h airtime without GPS (CoMo AV + easy GPS approx. 140 h airtime). Important: Make sure you load the compartment properly.

  • Page 22: Satellite-State-Indication

    2.8.3 Satellite-State-Indication This indication keeps you informed about GPS-reception. If the core of the indication flashes, the GPS is in search-mode. For every satellite found, one dot lights up. Although your GPS is capable of receiving up to 16 satellites, the indication only shows up to 6.

  • Page 23: Track And Northpointer

    2.8.5 Track and Northpointer To define a track the GPS has to be moved horizontally by a speed of at least 1.5 km/h whether you are flying or walking. Remember: This is not as responsive as a magnetic compass! flight-direction north track indication only from 1,5 km/h on!

  • Page 24: Glide Ratio Over Ground (L/D Ratio)

    2.8.7 Glide Ratio over Ground (l/d ratio) The glide ratio over ground is the ratio between your speed over ground (delivered by the GPS module) and the digital vario value. Example: Flying at 36 km/h (10 m/s) while descending at 1 m/s means your glide ratio over ground is 10.

  • Page 26: Erasing The Olc-Logger Memory

    3.5.2 Erasing the OLC-Logger Memory The memory of the OLC-Logger will be erased completely in only one step (flash memory). Ensure that all important flights have been transferred to the PC before erasing the memory. The function "erase memory" is in the menu: "settings"–"logger". Tip: We recommend that you erase the memory immediately after transferring data to the PC.
