Duty Time

IN PRACTICE

Part 135 duty limits are complex but a typical maximum is 14 hours of duty including up to 10 hours of flight time. When a customer requests a late departure on a long mission, the operator may have to schedule a second crew or position the aircraft the day before.

Where duty time sits in the flight day. Duty time is one of the moving parts the operator's flight department coordinates between booking and departure. It interacts with crew scheduling, dispatch, handling, customs and the cabin service plan, so a delay or change in duty time can ripple through the entire trip if it isn't surfaced early.

What duty time means for passengers. From a passenger's seat, duty time should be invisible — you arrive at the FBO, board, and depart. As your broker we monitor duty time status in the background and only raise it with you when it affects your schedule, your routing or your experience on board.

Who is accountable for duty time. The Part 135 (or equivalent EASA) operator holds operational control and is accountable for duty time. Brokers cannot lawfully exercise operational control and we don't pretend to. What we do is verify that the operator's procedures around duty time match the standard we promise our clients.

How duty time can affect price and availability. Anything that adds time, fuel or crew duty to a trip flows into the quote. Duty time can determine whether an aircraft is legal to fly your route at the weight you need, whether a second pilot or cabin crew is required, and whether the trip is feasible at all from a particular airport at a particular time of day.
