How to Use This Calculator
- Enter distance in miles and cruise speed.
- Add wind (positive = tailwind, negative = headwind).
- Use Commercial Airline tab for gate-to-gate block time with buffers.
- Switch to Professional for full breakdown including holding allowance.
Formula
Ground Speed = Cruise Speed + Wind
Airborne Time = Distance ÷ Ground Speed
Block Time = Airborne + Climb + Descent + 2×Taxi + Holding
Example
NYC→LAX 2,450 mi, cruise 550 mph, 100 mph tailwind → GS = 650 mph → airborne 3.77 h + 50 min buffers + 30 min taxi = ~4.6 h block time.
Frequently Asked Questions
- Block time is total gate-to-gate time: taxi out + climb + cruise + descent + taxi in + any holding. Airlines schedule using block time, which is longer than pure airborne time.
- Tailwinds add to ground speed; headwinds reduce it. A 100 mph jet-stream tailwind on an eastbound transcon saves roughly 30–45 minutes versus westbound.
- Narrow-body jets (737/A320) cruise near 530 mph; wide-bodies (777/787) near 560–590 mph. The default 550 mph is a practical average.
- Aircraft spend ~20 min climbing and ~30 min descending at lower speeds. Ignoring these phases underestimates total time, especially on short routes.
