Abstract :
Holdings are aircraft maneuvers to wait in a safe area (Protected airspace)
before being allowed to continue the next flight segment. For example, in
conditions of crowded air traffic, aircraft are required to hold in certain positions
and heights while waiting for their turn to land. The potential for aircraft holding
holding can be influenced by various things, one of which is the density of air
traffic in almost all airports in Indonesia, including the Ahmad Yani Airport in
Semarang.
The purpose of this study was to determine how much potential costs caused
by holding flight at Ahmad Yani Airport in Semarang by using holding
calculations on Standard Arrival Route (STAR) RWY-13 and RWY-31 in May
2018. The holding flight calculation was carried out by step by step from
calculating normal time arrival, flight time of holding, estimating takeoff weight,
estimating fuel burn, estimating landing weight, calculating holding fuel by using
interpolation formula, and calculating the holding cost of each aircraft.
From the calculation phase that has been explained, it can be seen that the
potential costs incurred by the holding flight for the lion air Rp 151,087,717,
Citilink Rp. 26,274,489, Batik Air Rp. 65,286,650, Garuda Indonesia Rp.
131,606,383, Air Asia Rp. 19,177. 245, Sriwijaya Air Rp. 9,729,825.
