IATA IOSO Manual
DSP 6.4.4 The Operator shall have a system of operational control to ensure that when a destination
alternate airport is not required, the aircraft carries sufficient fuel and oil to:
i) Turbojet Operations:
Fly to the destination and additionally fly 30 minutes at holding speed at 1,500 feet above the planned destination airport and to have an additional amount of fuel sufficient to provide for the increased consumption on the occurrence of other operational contingencies. If the destination airport is isolated, sufficient fuel to fly to the destination and thereafter for a period of two hours at normal cruise consumption.
So no mention of two runways.
So does "other operational contingencies" include single runway ops?
My company does not think so but many of our pilots do.
Looking for more feedback please.
