PREFACE
R MSN 0002-0860
Whenever holding is anticipated, it is preferable to maintain cruise level and
reduce speed to green dot, with ATC clearance, to minimize the holding
requirement. As a rule of thumb, a 0.05 Mach decrease during one hour equates
to 4 minutes hold. However, other operational constraints might make this option
inappropriate.
A holding pattern can be inserted at any point in the flight plan or may be
included as part of the STAR. In either case, the holding pattern can be modified
by the crew.
HOLDING SPEED AND CONFIGURATION
R MSN 0002-0860
R(1)
If a hold is to be flown, provided NAV mode is engaged and the speed is
managed, an automatic speed reduction will occur to achieve the Maximum
Endurance speed when entering the holding pattern. The Maximum Endurance
speed is approximatively equal to Green Dot (it can be between Green Dot and
Green Dot + 10 knots, depending on aircraft weight and flight conditions)and
provides the lowest hourly fuel consumption.
If the Maximum Endurance speed is greater than the ICAO or state maximum
holding speed, the crew should select flap 1 below 20.000 ft and fly S speed.
Fuel consumption will be increased when holding in anything other than clean
configuration and Maximum Endurance speed.
IN THE HOLDING PATTERN
R MSN 0002-0860
The holding pattern is not included in the descent path computation since the
FMGS does not know how many patterns will be flown. When the holding fix is
