1. What Is Total Flight Time?

Total Flight Time (TFT) represents the complete duration of flight operations including both block time (wheels-up to wheels-down) and taxi time (ground movement before takeoff and after landing). It provides a comprehensive measure of aircraft utilization.

2. How Does The Calculator Work?

The calculator uses the TFT equation:

\[ TFT = Block\ Time + Taxi\ Time \]

Where:

\( Block\ Time \) — Time from aircraft pushback/engine start to arrival at gate/engine shutdown
\( Taxi\ Time \) — Time spent moving on ground before takeoff and after landing

Explanation: This calculation provides the total operational time for flight planning, crew scheduling, and aircraft maintenance tracking.

3. Importance Of TFT Calculation

Details: Accurate TFT calculation is essential for flight operations management, crew duty time compliance, fuel planning, maintenance scheduling, and operational efficiency analysis.

4. Using The Calculator

Tips: Enter block time and taxi time in hours (decimal format acceptable). Both values must be non-negative numbers representing valid time durations.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between block time and flight time?
A: Block time includes all ground operations from pushback to arrival at gate, while flight time typically refers only to airborne duration.

Q2: Why is taxi time included in total flight time?
A: Taxi time represents significant operational duration that affects crew duty limits, fuel consumption, and aircraft utilization metrics.

Q3: How accurate should time inputs be?
A: For operational purposes, times should be recorded to the nearest minute (0.0167 hours) or as specified by company procedures.

Q4: Does TFT affect crew duty limitations?
A: Yes, TFT is often used in conjunction with other factors to determine crew duty and rest requirements under aviation regulations.

Q5: Can this calculator be used for multiple flight segments?
A: This calculator computes TFT for a single flight leg. For multi-leg operations, sum the TFT for each individual segment.
