With the continuous increase in the number of passengers and the
emergence of low-cost companies, the commercial aviation sector has
become a highly competitive one. Thus, airlines need to operate as
efficiently as possible in order to make a profit.
The aircraft turnaround stage is one of the most critical
processes that airlines and airports have to face in their daily
operations. The turnaround of an aircraft comprises all tasks that
need to be completed since it arrives to the assigned gate until it
is ready for departure. These activities include: boarding and
disembarking passengers, cabin-cleaning and catering, aircraft
maintenance and re-fueling, loading and unloading of baggage and
cargo, security checks, etc.
The Table below describes the tasks and steps involved in the
aircraft turnaround for Hala Airways. The focus of the process
improvement will be for the 1 – 4 pm shift.

a) In case Hala Airways wanted their gate to be serviced
by one crew only during the 1 – 4 pm shift, how many aircrafts can
be processed during that shift? What is the cycle time associated
with this arrangement?
b) Hala Airways would like to increase the number of
flights processed to 6 aircrafts/shift. How many actual crews will
be needed to achieve this target and what will be the time needed
for every flight? What is the efficiency of this arrangement?
c) In order to be able to process even more flights, Hala
Airways is ready to increase their staff to 7 crews. Help Hala
Airways design a system that will process the maximum number of
flights with 7 crews. What is the efficiency of the new system?
