Nav databases - size constraints
Does anybody understand Nav database formats?
We fly a bunch of older A319s with a 400k database and I'm trying to understand the approach and waypoint constraints on a databases this size in North American airspace. Our newer FMSs are 10 meg so obviously Honeywell is expecting that the larger size is required but not being a pilot or a nav database specialist I'm having a difficult time understanding why the extra size is required and in deciding/justifying if we should upgrade our older A319 FMS's.
