XTreme EFIS - STRATOMASTER Instrumentation MGL Avionics

XTreme-EFIS Operating Manual Page 29Hobbs:The XTreme contains a password protected Hobbs timer. The Hobbs time can be set to the current known engine time inthe “TIMERS SETUP” menu. The Hobbs timer will only increment when the RPM is greater then the “HOBBS MINIMUMRPM”.Maintenance:This timer is set in engine hours and it will count down to zero when the engine RPM is greater then the “HOBBSMINIMUM RPM” value as set in the “TIMERS SETUP”. A good use for this function is to set the hours until your nextspark plug change or engine inspection.The purpose of this function is to assist you in determining remaining hours until maintenance will be required. It is notintended as a replacement for the aircraft's maintenance log. It is therefore important that the aircraft's maintenance logbe maintained in the normal manner. You should further use your own discretion in performing maintenance earlier thanindicated should any aircraft performance problems arise.A maximum of 999 hours can be entered as a maintenance interval. Areminder message will appear on startup when zero hours areremaining. The reminder message will automatically disappear after 10seconds or if the pilot presses any key. Engine running time for thepurpose of the maintenance timer is defined as the run time where the engine RPM is greater than the “HOBBSMINIMUM RPM” value as set in the “TIMERS SETUP”.Airframe:This timer operates similar to the engine maintenance timer but is based on flight time. You might use it to schedulethorough airframe checks at intervals, perhaps every 25 or 50 hours.A reminder message will appear on startup when zero hours are remaining. Thereminder message will automatically disappear after 10 seconds or if the pilotpresses any key.3.10.11 Information area 2Volts:The XTreme can measure the supply voltage up to 30Vdc. The supply volts parameters can be configured in the “VOLTSSETUP” menu.OAT:Outside air temperature can be measured using the external temperature probe. The OAT parameters can be configuredin the “OAT SETUP” menu.Glide Ratio:Glide ratio can be measured up to 1:99. Glide ratio is measured as a ratio between forward movement of the aircraft vs.vertical sink rate. Please note that the forward movement of the aircraft is not synonymous with horizontal forwardmovement relative to the earth surface but is a function of airspeed.Climb Ratio:Climb ratio can be measured up to 1:99. Climb ratio is measured as a ratio between forward movement of the aircraft vs.vertical climb rate. Please note that the forward movement of the aircraft is not synonymous with horizontal forwardmovement relative to the earth surface but is a function of airspeed.
