## Max Duty Description
Stop guessing your duty limits. Let Max Duty do the math!

Did you know that under Transport Canada’s regulations, your maximum duty period dynamically changes based on your exact report time, acclimatization, average flight leg duration, and the total number of flights you operate?

Trying to decipher complex CARs tables and charts while preparing for a flight is a recipe for stress. Whether you are a commercial pilot, a flight dispatcher, or a commuter, Max Duty takes the guesswork out of compliance so you can focus entirely on the flight deck.

Why Pilots Choose Max Duty:
• Instant Dynamic Calculations: Input your report time, leg count, and sector lengths to get your exact maximum allowable duty period in seconds.
• Split Duty Support: Easily calculate legal extensions for split duty periods based on your rest opportunities and Transport Canada limits.
• Built for the Flight Deck: A clean, lightning-fast, and intuitive interface that works flawlessly on the go - no internet connection required!
• Error Prevention: Avoid costly, stressful scheduling violations before you even step onto the aircraft.

Stop flipping through regulations and manually averaging flight legs. Download Max Duty today, clear your mind for the day ahead, and let us handle the math.

Disclaimer: Max Duty is intended for situational awareness and reference purposes only. It does not replace your airline’s approved tracking software or operations manual. Always cross-reference results with official Transport Canada Civil Aviation Regulations (CARs) to ensure legal compliance before operating an aircraft.

## Max Duty Reviews in Canada

### ***** "Must have app"
Quick and simple to use a must have for pilots
-- Hhhhyhqwwwdxcvbhuujssrgc, 2023-11-11

### ***** "Great app"
Great app does exactly what it says very straight forward, also references the CARs section it takes it’s data from.

Would be great to see an Apple Watch app or a widget for iPhone would make this great for quick referencing your duty day and time remaining.
