1. Nav calculator

The RightBase Navigation calculator automates typical E6B planning calculations.  It consists of six input fields:
  • Wdir: Wind direction in degrees (from met report)
  • Wv: Wind velocity (speed) in user-specified units (from met report - normally knots)
  • FF: Fuel Flow in user-specified units (from airplane manual)
  • TAS: True Airspeed in user-specified units (from airplane manual - normally knots)
  • CRS: Course (desired track over ground) in degrees (from chart), congruent with Wdir (e.g. true, magnetic or compass)
  • Dist: Distance, using congruent units as for TAS (from chart).  For example, if TAS is entered in knots, then Dist values must refer to nautical miles (NM).
Adding values in a field is simple - just tap onto the input box.  Any existing values will disappear and a numeric keypad allows you to type in new values.  Use the 'previous' and 'next' buttons to easily cycle through the fields.

Once all six values have been entered, click the 'Calc!' button and values for the following variables are calculated in a snap:
  • GS: Groundspeed; units are the same as those used for TAS and Distance
  • HDG: Heading to steer in degrees (true, magnetic or compass)
  • Time: Time in minutes
  • Fuel: Amount of fuel required; units are the same as those specified for Fuel Flow (FF).  
These output values should be recorded onto a navigation log.

The process reduces time spent using a conventional E6B calculator.
