slot restrictions for charter flights

Duty Time

A pilot or crewmember is logging duty time whenever they are providing private jet charter services in any capacity. Current FAA regulations impose strict limitations on:

  • How long a crewmember can work in a single stretch
  • How long a crewmember must rest before resuming duty
  • Amount of duty time a crewmember can log in a week, month or year

For example, under normal circumstances, if a pilot is the sole crewmember for a charter flight, his or her total duty time may not exceed eight hours during any 24 consecutive hours. There are ways to increase the permitted duty time, however, it requires lengthening the mandated rest period afterwards.

The Effect on Long-range Jet Charter Services

As you can see, duty time has significant implications on planning private jet charter services. If a group of passengers wants to travel overseas on a long-range aircraft—such as a Gulfstream G550 charter—they will have to wait for the crew to undergo the required rest period before they can complete the return leg. Most of the time, that won’t be an issue. However, if the traveling party requires a quick turnaround, the private jet charter cost will increase.

The rules governing duty time are covered by Part 135 and Part 121 of the Federal Aviation Regulations.
