Actually, it is less for a given VOLUME of air, not
mass (a pound of air  is a pound is a pound).  That's
why EFI cars do better with mass flowmeters at
altitude.  It is the density that lessens at altitude.
 density is = 2.7 * pressure (in psia) / temperature
(in dgrees rankine, which is F +460).  Lower altitude,
higher pressure, denser air.
