Travis,
Many thanks for your answer.
EFB certainly does a good job of interpreting the data and drawing the charts. I have noticed on a few arrival procedures in the UK, Altitude restrictions on the EFB chart but not in the official NATS chart. So I assume this would be contained within the Navigraph Airac and EFB just produces these altitude restrictions from there.
Again in the UK charts, the Arrival Procedure turns appear to only show those for the larger Cat C and D aircraft, at the moment I'm flying the RealAir Duke Turbine version and need to use the 'tighter' Cat A, B procedure turns - is this possible with EFB.
