• Threshold Time: Regulations require an aeroplane not to operate
on a route where the flight time at single engine cruise speed to
an adequate en-route alternate aerodrome exceeds a Threshold
Time established by the State (refer to page 62 – ETOPS). Note:
When operating without Threshold Time limit, check the ‘No
Threshold Time Limit’ option
• Diversion TAS: Single engine cruise speed based on one-engine-
out cruise speed in standard atmospheric conditions. This value
is calculated automatically, but can be adjusted if required.
• Threshold Dist: Given the Threshold Time and the Diversion TAS
a Threshold Distance can be calculated. This is the maximum
distance an airplane may operate from an adequate airport wit-
hout ETOPS approval.
• T/O Altn Dist: A Take-Off Alternate aerodrome shall be selected
if it would not be possible to return to the departure aerodrome
for meteorological or performance reasons. The Take-off alter-
nate aerodrome shall be located within one hour flight time at
one-engine-out cruise speed in standard atmospheric condi-
tions. For ETOPS approved airplanes, the distance may be exten-
ded to the Max Diversion Time, up to a maximum of two hours.
• TOPCAT Performance Module: PFPX allows performing Take-Off
and Landing Performance Calculation by selecting the appropriate
performance module. Note: This requires a full version of TOPCAT.
• Min Rwy Length, Ceiling, Visibility and Airport Type: Enter the
minimum runway length, weather requirements and type for an
aerodrome to be determined as Destination Alternate, Enroute
Alternate or Adequate Airport.
• Default Climb, Cruise and Descent Speed schedule: The speed
schedule used for flight operations has a great influence on ope-
rating costs. Obviously, the faster an airplane flies, the lower the
flight time, but a higher amount of fuel is required.Adjust the
settings for the default speed schedule used for climb, cruise
and descent calculations from the Origin aerodrome to the Des-
tination Aerodrome.
