We investigate the spatial and temporal behavior of emission in flaring loops observed by AIA's 193 (Fe XXIV/XII), 131(Fe XX), 094 (Fe XVIII), 335 (Fe XVI), 211 (Fe XIV), and 171 (Fe IX) channels for two C class flares and one M class flare. Plotting light curves from loop-top areas in the six channels reveals the temporal distributions as a function of the ionization stages, with the same characteristic behavior identifiable in all three flares. The order of appearance is from the highest ionization state (FeXXIV) to the lowest (Fe XVI), and the observations are compared with the Reeves, Warren & Forbes (2007) model of flare loop energization, calculated for the various AIA channels. We also model the effects of non-equilibrium ionization on the simulated light curves.
