The Civil Aviation Authority (CAA) said safety is its "number one priority" after a poll by the pilots' union Balpa showed more than a half had fallen asleep while in flight.
A CAA spokesman said: "We think the new European flight-time limitation regulations maintain the UK's current high safety levels, and will actually increase safety for UK passengers travelling on some other European airlines.
"The changes will give the CAA far greater access to airline data to help us oversee fatigue risk management. We will shortly begin working with UK airlines over the introduction of the new system."
A review into offshore helicopter operations in the North Sea will compare UK fleets with those in Norway.
The CAA said its review will be undertaken with the Norwegian CAA and the European Aviation Safety Agency and will pay particular attention to:
- Operators' decision making and internal management
- The protection of passengers and crew
- Pilot training and performance
- Helicopter airworthiness.
The review follows five accidents in the last four years, the last of which in August this year claimed four lives.
The Civil Aviation Authority (CAA) has announced a review of offshore helicopter operations in the North Sea after an aircraft carrying 16 oil workers went down in August, killing four people.
The Helicopter Safety Steering Group temporarily grounded the Super Puma fleet after the incident, but lifted the ban after concluding that there was no evidence to support it.
The CAA said the review will be undertaken jointly with other safety watchdogs and advised by a panel of independent experts in order to make recommendations aimed at improving the safety of offshore flying.
Air passengers will today be given the first indication of how fares will change over the next five years at the capital's three main airports.
The Civil Aviation Authority (CAA) will outline its initial proposals for how much airlines will be charged for using London's three main airports between 2014 and 2019.
The plans will have an impact on fares at Heathrow, Gatwick and Stansted airports - the only three airports that are regulated by the CAA.
A final decision is due in January next year.
