Seatbelt Sign

As I do my flights on IF, one of the many troubles I have is wondering if it is realistically safe to turn the fasten seatbelt sign off. So my question is, what information should I use to determine when I should turn it off. What are the “parameters” or “criteria?” Does it vary in different aircraft?

I usually turn it off over 10 000 ft. (On if there’s turbulence)


There’s no realistic passengers (except weights) on IF’s planes, so I simply do it’s operations, just for extra realism.

I turn them off when:
Reaching cruising altitude with smooth air
At the gate

On when:
Unexpected rough air
In descent


usually you use the seat belt sign at pilots discretion unless its deemed unsafe or the flaps are deployed

In real life they will typically do it at 10,000ft as standard procedure should the conditions allow for it.

There is no specified altitude, except the minimum altitude specified by the local authorities (varies around 1000’ to 2000’). If the seatbelt sign switch is left in AUTO the lights will extinguish when the flaps reach UP (Boeing). This would occur anywhere from 1500’ to 4000’ depending on the airport/operator. If turbulence is suspected, or if company procedures dictate, the switch will be left ON until the ride is smooth enough to allow passengers out of their seats. Each airline develops their own procedures to ensure that all persons on the aircraft are seated according to regulation and safety. At Qantas is the seatbelt sign is on all passengers and crew are to be seated with their seatbelts fastened, other airlines allow crew to be upstanding while the sign is still on. Qantas’ view is that everyone on the aircraft is to be protected in this period. I hope this addresses your question.
