FAA Speed Limits
FAR 91.117 imposes a speed restriction of 25 below 10,000 for turbo jet aircraft.
It has been put to me that this is applicable only out to 5 miles offshore.
Try as I might I can find no reference to the area of application of the restriction.
It has always been my understanding that it applies to any designated US airspace regardless of proximity to the US coast.
If any one out there can point me in the right direction to find verifiable data on the application of this restriction, I would appreciate it
