LIMITATIONS
For RNAV operations in terminal airspace, obstacle clearance
protection, up to the Final Approach FIX (FAF), will assume that
airplane comply with the required RNAV
accuracy requirements;
Obstacle clearance altitude is based upon the infrastructure giving
the poorest precision;
The minimum flight crew are 2 Pilots;
The system must display essential information in the Pilot’s primary
field of view such as:
Lateral deviation;
TO/FROM waypoints;
Failure flag (failure of RNAV system);
Where GNSS is used, the signal must be acquired before the takeoff
roll commences and GNSS position may be used instead of runway
update;
Where reliance is placed on the use of radar to assist contingency
procedures, its performance has been shown to be adequate for that
purpose, and the requirement for a radar service is identified in the
AIP;
RNAV operations must use FMS to control all lateral navigation
functions. For FMS limitations, refer to Section 1-01-60 (Limitations,
System: FMS) of AOM;
The airplane RNAV system must display the following information to
the flight crew:
The active (TO) waypoint and distance/bearing to this point;
Ground speed or time to the active (TO) waypoint;
RNAV system failure;
Alternate means of displaying navigation information, that is
sufficient to perform cross-checks.
