iFACTS

Question 1

What can cause a CFL deviation alert?

Answer 1

• Descend when ready or level-by clearance and aircraft has not started descent by anticipated top of descent point.
• Aircraft has deviated from the entered CFL by more than 200ft.
• Aircraft levels off before achieving the entered CFL.
• Aircraft does not begin climbing within 30 secs of entering a CFL.
• Aircraft does not begin descending within 40 secs of a descend NOW CFL being entered.

Question 2

What can cause a HDG deviation alert?

Answer 2

• Aircraft does not achieve entered heading (+/- 5 degrees) within 3 deg/sec plus 15 secs.
• Aircraft has deviated from the entered heading by 5 degrees.
• Aircraft has deviated from the predicted path by 2nm (whn heading entered).

Question 3

When will a TDB display a NO TRAJ deviation alert?

Answer 3

When no primary trajectory can be created because the system has no route and/or level information.

Alerts 3 mins before end of route/off route fix. Will not display an alert when a flight is coming to the end of its standard route but will still produce a trajectory.

Question 4

When entering speed data, how does iFACTS differentiate between Mach and IAS?

Answer 4

Mach: two digits starting with a 5 or greater.
IAS: three digits starting with a 4 or less.

Can enter together with no spaces.

Question 5

How does the LAD show InComm and not yet InComm flight interactions?

Answer 5

InComm flights, or flights not yet InComm but within the sector VOI, use a trajectory derived from CFL, or if climbing or descending the trajectory extends from AFL to CFL. The callsign label in the LAD will have a pointed left-hand end when hovered over.

Not yet Incomm flights outside of the sector VOI will use a single-level trajectory derived from the NFL unless an SCL is present. The callsign label will have a squared left-hand end when hovered over. The label will be placed at the NFL and may not indicate the flight’s current AFL.

Question 6

When MUST the Planner use the iFACTS tools when considering an offer?

Answer 6

• Joining or Crossing requets including Cleared Flight Paths (CFPs).
• Late Offers.
• Holding.
• Vertical Coordination when giving away a Flight Level within the sector (including the highest and lowest level).
• Flights offered with an SCL.
