Requirements Concerning Operations in Night Visual Flight Rules (NVFR)
PURPOSE
This Commercial and Business Aviation Advisory Circular (CBAAC) is intended to
bring to the attention of Air Taxi operators the requirements for operations in Night
Visual Flight Rule (NVFR) flight.
BACKGROUND
Following a fatal accident, concerns have been raised about the operation of
aircraft in NVFR. The accident aircraft was operating in uncontrolled airspace. Other
company pilots who spoke to Transportation Safety Board (TSB) investigators were not
familiar with the NVFR requirement to fly an established route.
Transport Canada (TC) wishes to ensure that all NVFR operators understand the
obstacle clearance requirements and weather minima for NVFR.
ACTION
Canadian Aviation Regulation (CAR) 602.115 requires a visibility of
three miles for NVFR flight. Furthermore, CAR 703.27(a) prohibits enroute NVFR at
less than 1000 feet above the highest obstacle. NVFR must be conducted along air
routes or routes specifically established by the air operator and designed in
accordance with Commercial Air Service Standard (CASS) 723.34. The Company
Operations Manual (COM) must include information and direction pertaining to NVFR
operations. CASS 723.105(1)(j) refers.
Air operators who choose to develop their own NVFR routes will have to submit
their proposals to TC in the normal manner.
The generic operations manual for Air Taxi operators will be corrected in the
revision that is currently underway to include all pertinent information concerning
NVFR operations.
CONCLUSION
Company operations manuals must contain all the information required by the CASS
regarding NVFR operations, and pilots must be aware of, and operate in accordance
with, the NVFR procedures contained in the COM.

Circulars (CBAAC) are intended to provide information and guidance regarding
operational matters. A CBAAC may describe an acceptable, but not the only,
means of demonstrating compliance with existing regulations. CBAACs in and of
themselves do not change, create any additional, authorize changes in, or
permit deviations from regulatory requirements. |
