R-ATP Calculator: your ATP & 1,500-hour minimum
Last updated July 3, 2026
Restricted ATP rules let some pilots reach the airlines with fewer than 1,500 hours. Pick your pathway and enter your flight time to see your minimum and how far you have to go.

Without a qualifying military or aviation-degree pathway, the standard ATP minimum is 1,500 hours (minimum age 23). The reduced number is total time — you still need the ATP's other experience (about 500 hrs cross-country, 100 hrs night, 75 hrs instrument, and 250 hrs PIC).
How the restricted ATP works
The standard ATP certificate requires 1,500 hours of total time. Under 14 CFR § 61.160, certain military-trained pilots and graduates of approved aviation degree programs can earn a restricted ATP with fewer hours and fly as second-in-command (SIC) for a Part 121 airline until they reach the full ATP. The total-time minimums are:
| Pathway | Minimum total time |
|---|---|
| U.S. military-trained pilot | 750 hours |
| Bachelor's degree, aviation major — 60+ aviation credit hours | 1,000 hours |
| Bachelor's degree, aviation major — 30–59 aviation credit hours | 1,250 hours |
| Associate's degree, aviation major — 30+ aviation credit hours | 1,250 hours |
| No qualifying pathway (standard ATP) | 1,500 hours |
The reduced number is total time. You still need the ATP's other experience (about 500 hours cross-country, 100 hours night, 75 hours instrument, and 250 hours PIC), and R-ATP applicants must be at least 21 (23 for the unrestricted ATP). Degree pathways require the institution to hold the FAA authorization — confirm with your school and the FAA.

Frequently asked questions
What is a restricted ATP (R-ATP)?+
A restricted Airline Transport Pilot certificate lets qualifying pilots earn an ATP with fewer than 1,500 total hours and act as second-in-command (SIC) under Part 121. It's authorized by 14 CFR 61.160 for military-trained pilots and graduates of approved aviation degree programs.
How many hours do I need for an R-ATP?+
It depends on your pathway: 750 hours for U.S. military-trained pilots, 1,000 hours for a Bachelor's degree with an aviation major and 60+ aviation credit hours from an approved school, and 1,250 hours for a Bachelor's with 30–59 credits or an approved Associate's degree with an aviation major.
How many hours do I need with an aviation degree?+
1,000 hours with a qualifying Bachelor's (60+ aviation credit hours) or 1,250 hours with a qualifying Bachelor's (30–59 credits) or Associate's degree in an aviation major, provided the institution holds the FAA authorization.
What's the difference between an R-ATP and a full ATP?+
An R-ATP has restricted privileges — you can fly as SIC under Part 121 and the minimum age is 21. A full, unrestricted ATP requires 1,500 hours and age 23 and allows you to act as pilot-in-command. R-ATP holders upgrade to the full ATP once they meet those thresholds.
Do the other ATP experience requirements still apply?+
Yes. The reduced number is total time only. You still need the ATP's other experience — roughly 500 hours cross-country, 100 hours night, 75 hours instrument, and 250 hours PIC — per 14 CFR 61.159.
How long does it take to build these hours?+
Most low-time pilots build hours by flight instructing, flying skydivers, aerial survey, banner towing, or Part 135 cargo. Timelines vary widely — see our guide on how long it takes to get 1,500 flight hours.
