FLIGHT MONITORING AND FLIGHT WATCH — RELEVANT SAFETY INFORMATION
Relevant safety information is any element that may affect the safety of the flight, such as:
(a) an aircraft technical failure (e.g. failures where flight operations personnel can help to calculate the landing distance or new trip fuel or to update the aerodrome minima);
(b) unforeseen hazards:
(1) air traffic (e.g. delays and/or long distance to complete the approach, extensive use of radar vectoring);
(2) meteorological conditions (e.g. DH and aerodrome operating minima, adverse or extreme meteorological conditions);
(3) aerodrome and runway status (e.g. insufficient runway length due to brake failure, obstruction or closure of the runway, runway contamination, failure or malfunction caused by on-ground navigation or approach equipment);
(4) navigation aid status (e.g. failure of the navigation aids);
(5) availability of communications (e.g. failure of communications capabilities, interruptions, interferences, change of frequency channels); and
(6) terrain and obstacles (e.g. geophysical phenomena (volcanic eruptions, earthquakes, tsunami), difficult terrain at an unplanned aerodrome (large bodies of water, mountains);
(c) updates of the operational flight plan when they affect the fuel reserves:
(1) diversion to an en route alternate (ERA) aerodrome, a destination alternate, or a take-off alternate aerodrome;
(2) change of the runway selected for landing if the new runway is shorter;
(3) location of the decision point or the point of no return (PNR) due to, for instance, change in altitude, in wind data, etc.;
(4) significant in-flight change of the flight route compared to the route in the flight planning; or
(5) significant deviation from the planned fuel consumption; and
(d) position reporting:
(1) flight-monitoring personnel should report in every phase of the flight: taxi, take-off, climb, cruise, cruise steep climb, descent, approach, landing;
(2) flight watch provides active tracking; and
(3) where no real-time automatic position-reporting is possible, the operator should have an acceptable alternative to ensure in-flight reporting at least every hour.
Flight monitoring and flight watch require relaying safety information impacting flight safety. This includes aircraft failures, unforeseen hazards like weather or runway issues, navigation problems, and communication disruptions. Updates affecting fuel reserves, route changes, and position reporting throughout all flight phases are also crucial for safe air operations.
