ZuluScript: Advanced Currency Example 1
<b>Example: At Least 10 Hours as PIC or SIC in Rotorcraft in 90 Days</b>
<div class="h10"> </div>

<div>Initialization script:</div>
<pre>
  var tottime = 0.0;
</pre>
<div>Loop script:</div>
<pre>
  var cat = getfieldstr("Category");
  var role = getfieldstr("Crew Role");
  var flttime = getfieldnum("Day Flight Time") +
   getfieldnum("Night Flight Time");
  
  if (strequal(cat, "Rotorcraft"))
  {
    if (strequal(role, "PIC") || strequal(role, "SIC"))
    {
      tottime = tottime + flttime;
      if (tottime >= 10.0)
        currency_ok = 1;
    }
  }
</pre>

<div>How it works:</div>
For each flight, we add the values of Day Flight Time and Night Flight Time into 
a variable called <code>flttime</code>. We check that the category of the aircraft
associated with the flight is "Rotorcraft" (this must match exactly with the 
Category drop-down on the Aircraft Definition screen). If this check passes, we
then check that the flight's Crew Role is either PIC or SIC. If this check
also passes, we then accumulate <code>flttime</code> into <code>tottime</code> and 
check the total value of <code>tottime</code>. If it's
at least 10.0, the currency is valid.
