1. Paper seals must be marked in a manner such that there is incontrovertible proof after the flight that seals have not been tampered with such as by marking with the glider registration the date time and OO s name and signature The use of adhesive plastic tape is not satisfactory for IGC approved sealing because it can be peeled off and re fitted Gummed paper tape is recommended as used for sealing drum type barographs The OO must seal the FR unit to glider parts which are part of the minimum standard for flight It is accepted that such parts can be removed for purposes such as servicing such parts include the canopy frame instrument panel and centre section bulkhead fittings If the FR is sealed to such removable part if such a part is transferred between gliders any FR seal for the previous glider must be removed 4 Security Seals Physical and Electronic A silver coloured tamper evident seal with the European CE Mark and the manufacturer s name is fitted over one of the case securing screws In addition an internal electronic security mechanism is included and the electronic security check will no longer produce a valid IGC file if the case has been opened On switching on after the LCD screen shows the unit serial number it should then show Security Seal OK for a short time If the FR is found to be unsealed either physically or electronically it must be returned to the manufacturer or his appointed agent for investigation and r
2. Takeoff The pilot must ensure that the time and point of takeoff has been witnessed and recorded for comparison with that recorded by the GNSS FR see para B1 2 A5 Connection to Ports Although this approval does not presently require sealing of any ports or plugs no attempt must be made to pass unauthorised data into the FR See paras 2 3 and 3 in the conditions of approval A6 Use in Motor Gliders including self sustainers When fitted Hardware versions 3 3 or later the internal microphone system automatically records a three figure ENL Engine Noise Level value with each fix The FR must be placed so that engine noise is clearly received when the engine is giving power it should not be covered for instance although automatic gain will continue to ensure high ENL readings under power Pilots should note that other cockpit noises will produce ENL readings and avoid those which could be mistaken for use of engine Generally the frequency filtering built in to the FR will avoid any problems but it should be noted that sideslipping with the cockpit DV panel open sometimes produces a low frequency sound which will register as high ENL as will stall buffet particularly if it causes engine bay doors to pant Flight close to powered aircraft should also be avoided except for normal aero tow launches For ENL levels which have been recorded on GFAC tests see B 4 2 A7 After Flight The pilot must ensure that the time and point of landing has b

Logger Function In its capacity as an FAI Logger the VOLKSLOGGER continuously and uninterrupted as long as there is sufficient memory available see Chapter 6 1 1 Flight Data Memory records all data relevant to the FAI IGC Position e GPS Altitude e Pressure Altitude e Engine Run Noise Level The data are recorded in certain time intervals as soon as voltage is supplied Data will always be recorded even if the aircraft does not move and independent of the availability of GPS Reception The recording happens in the background independent of the screens displayed navigational modes menus etc The only possibility for the pilot to interact with the recording process is in the modification of the recording cycle logging interval adjustment definition of the turn point observation zone sector manual activation of the fast recording etc 5 3 Screen Displays In the operation of the logger you can choose with Key 1 between the main screens e NAVIGATION e POSITION INFO e MENU These screen names will also be used in the subsequent descriptions On the logger itself these designations will never be displayed rather it will be clear from the context which screen is active at the time In the following text the particular display screens and the meaning of their indications are described starting with hardware 3 3 see Type Label 12 13 5 3 1 Navigation The main navigation display screen offers all

Sector Note The radii remain in metric units even though nautical miles are selected for distances The proper input of values for the Turn Point Sector is a mandatory prerequisite for the proper functioning of the following performance attributes of the VOLKSLOGGER e Acoustic signaling for the positive rounding of the turn point e Automatic switching to the next turn point within the route task e Automatic change of the recording interval upon reaching the turn point 32 33 A careful study of chapter 5 5 2 Turn Point Sector Observation Zone is recommended in order to understand the necessary basic concepts 5 7 Basics of Data Input Introduction The operation of the VOLKSLOGGER requires in many places the input or editing of certain values or data Examples for this are e The change of basic settings such as Recording Parameters Contrast etc e The input of the flight declaration Therefore a precise understanding of the mechanisms for the data input are necessary if one wants to use the full functional capacity of the instrument The input of data requires some practice however since the whole spectrum of data types has to be covered with only three keys So is for instance after some familiarity the input of the task quite easy even when no PC is available 5 7 1 Field Types The data fields which are used in the VOLKSLOGGER can generally be grouped into three categories 1 asimple field e C
