B. Speed Limitations
Below FL100, an airspace speed limit of 250kt applies. In addition, this limit may be lower when published in procedures or when required by ATC.
C. Flight Plan Requirements
A Flight Plan is required for flights in all Controlled Airspace except Class E. In certain circumstances the Flight Plan requirement may be satisfied by passing flight details on RTF (see page 30). A Flight Plan comprises sufficient information to enable an ATC Unit to issue a clearance and for search and rescue purposes (Rule 29 of UK Air Navigation Order refers).
D. ATC Clearance and ATC Instructions
ATC Clearance is required for flight in all Controlled Airspace except Class E, and compliance with ATC instructions is mandatory.
In Class E Controlled Airspace pilots of VFR flights are strongly recommended to make their presence known to the appropriate ATC Unit and comply with ATC instructions.
Outside Controlled Airspace an aircraft receiving a service from an ATC Unit is expected to comply with ATC instructions unless the pilot advises otherwise.
