72 preparing peak period and Operational profiles -- Guidebook The Toolbox methodology assumes that, without peak spreading, peak period operations will grow at the same rate as annual operations. It also provides an alternate calculation that assumes an average degree of peak spreading as the forecasted annual operations increase.

Since hourly data on passenger levels is typically unavailable, additional steps are required for the estimate.
