2. GPU Analysis OVERVIEW
GPU USAGE
• Fuel Saving by implement FCP
• APU Life Saving
• Significant Cost Saving
ANALYSYS
• Calculate GPU needed for RON (Night Rest)
• Calculate GPU needed for Ex-RON (Before Departure)
• Calculate GPU needed during prolonged transit
gp g
• Identify GPU usage peak time and number of GPU needed

3. GPU Analysis ANALYSIS
ASSUMPTION
• Analysis based on GA and CT’s biweekly schedule
• Biweekly schedule used for period 01-15 July 2011
• Analyze for CGK, DPS, UPG, and SUB station
RON ANALYSIS
• Analyze based on Arrival Station and Standard Time Arrival
• The last flight and the next flight should be in different date
• The interval between those flight > 3 Hours
g
• GPU usage assumption 2 hours
• Sample Result

4. GPU Analysis ANALYSIS
BEFORE DEPARTURE ANALYSIS
• Analyze based on Departure Station and Standard Time Departure
• GPU usage assumption 2 hours for W/B and 1.5 hours for N/B A/C before STD
• Sample Result
TRANSIT ANALYSIS
• A l
Analyze based on Arrival St ti and St d d Ti
b d A i l Station d Standard Time A i l
Arrival
• GPU usage assumption 2 hours for W/B Aircraft
