EX60/14 is
specific to the 747-4 / 330 / 380 /767. When CASA issued the instrument in 2014, it would have been well aware of the inherent commercial range limitations of the airborne time of these specific types as well as established & longstanding operator practice. The 20 hours TOD allows for delays & diversions, rather than an every day normal operating practice.
The 787 transcends these previous types commercial limitations. In addition, will have to at least consider recent ICAO FRMS guidelines published in 2012 that seem to at least have some evidence based component, rather than simply pencilling in a larger number as new type range increased.
How many current pre-planned patterns on existing types have a 19 hour TOD? Because that is likely to be the norm form many crew on the 787, will CASA be justified in simply adding 787 to the next instrument?
