We had a situation where I work where they had a roster of 5 starts before sunrise, consisting of 2 pre-0600 reports (early starts) followed by an 0605(not a legal early, just a morning start) followed by a pair of earlies.
(forgive me for errors of legal/tech jargon, I've been off for a while!)
Technically legal due to it not being 3 earlies in a row. Did they seriously think that the extra 5 minutes lie-in would make it easy to do another 2 earlies.
Plan didn't last for very long. Thankfully the local Pilot Manager saw the roster and got it sorted.
Good company to work for....just that the roster planning was starting to look at legal maximums more as "targets"!
