In a previous article, EDR said:
Here is the question:
When you fill in the AIRSPEED box, do you give the actual indicated
airspeed for your cruise power setting?
Or, do you use the "groundspeed", based on winds aloft?

If you use the actual indicated airspeed, the math is not correct for
the time enroute.

They don't want the AIRSPEED so they can check your math, they want it for
separation purposes.

reach. Its magic -- its power -- is based on the very real human connections
that form 'round its threads of conversation... the relationships that are
kindled, flamed and, on occasion, extinguished and mourned." -deCadmus
