Calculate critical aviation KPIs including On-Time Performance (OTP), Cancellation Rates, and Average Delays to monitor operational health.
Regularity (Operated %) = (Total Scheduled - Canceled) / Total Scheduled × 100%
Departure Punctuality (OTP Dep) = On-Time Departures / Total Operated Flights × 100%
Arrival Punctuality (OTP Arr) = On-Time Arrivals / Total Operated Flights × 100%
Cancellation Rate = Canceled Flights / Total Scheduled Flights × 100%
Average Departure Delay = Total Delay Minutes / Total Operated Flights
In the highly complex world of aviation, data-driven decision-making is the bedrock of profitability and customer satisfaction. The is a specialized tool designed to process flight schedule and operations data into actionable Key Performance Indicators (KPIs). By integrating planned schedules with actual performance data, this calculator provides an immediate snapshot of an airline's operational health. Whether you are an operations manager, a schedule planner, or an aviation analyst, utilizing a allows you to move beyond raw data logs and understand the true efficiency of your fleet.
The core function of the is to bridge the gap between "what was supposed to happen" (the schedule) and "what actually happened" (operations). It focuses on the industry-standard definition of "On-Time," typically defined as a departure or arrival occurring within 15 minutes of the scheduled time. This adherence to standards ensures that the metrics generated—such as Departure Punctuality (OTP) and Regularity—are comparable across the industry. Sources like the International Air Transport Association (IATA) and the Bureau of Transportation Statistics emphasize these specific metrics as primary indicators of carrier performance.
Furthermore, the assists in Root Cause Analysis. By isolating "Average Departure Delay" and "Cancellation Rates," operators can identify if issues are systemic (e.g., unrealistic scheduling) or event-based (e.g., weather). While a standard calendar view offers a visual timeline, this calculation tool distills that timeline into hard numbers. Regular use of the helps airlines optimize block times, improve passenger connection success rates, and ultimately reduce the significant costs associated with irregular operations (IROPS).

Schedule consistency (or Regularity) measures how many flights actually operated versus how many were scheduled, regardless of timing. OTP (On-Time Performance) specifically measures punctuality—what percentage of the operated flights departed or arrived within 15 minutes of the schedule.
The 15-minute threshold is a global aviation standard. It accounts for minor operational variances that do not significantly impact the airspace system or passenger connections. A flight departing 14 minutes late is statistically considered "on time."
Canceled flights are generally excluded from average delay calculations because they did not fly. Including them would require assigning an arbitrary delay value (e.g., extreme duration), which skews the data. This calculator calculates delay based only on flights that operated.
Yes. Simply aggregate your data (sum up all scheduled flights, all on-time departures, etc.) for the week or month and input the totals. The formulas work for any time period as long as the inputs represent the same duration.
