I've seen things you people wouldn't believe.
Barbeques on fire by the chalets past the castle headland

All these moments will be lost in time, like icecream on the beach
Time for tea.

A radio signal carries information.

Erm... No

Not unless location is a consideration.

How does the average passenger determine when the aircraft is above 10,000

The PA comes on and a voice says 'Passengers may use electrical equipment
such as...'

How does the average passenger determine when the aircraft is above 10,000
feet?

By the "double ding" from the cockpit or the announcement from the FA.

Do you have any idea what the term "RF" stands for?

Not necessarily. But I can see the semantic argument.

MX's flight simulator doesn't have a PA for passengers. Anthony can't
