All electronic devices, including PDAs, laptop computers, handheld games, iPads, Ebooks and toys must be switched off during take-off and landing.
Qantas has various classifications for Personal Electronic Devices (PEDs)
The statement that ALL electronic devices must be turned off during takeoff and landing is not QANTASs policy.
PEDs are restricted by phase of flight.
eg unrestricted PEDs
Group 1:
Devices not restricted from use
Medical PEDs that are required for the essential
support of human life. Examples include:
• Medical implants, hearing aids, insulin pumps,
ventilators, electronic nerve stimulators,
automated external defibrillators and Airborne
Patient Medical Telemonitoring (APMT).
PEDs of the following kinds may be used at any time,
except when special operational restrictions are
applied by the Captain:
• Electronic watches, GPS, electric shavers,
video
and still cameras, pocket calculators and other
devices powered by micro-cell batteries and solar
cells.
it further goes on into category 2, 3 etc.
This information is available in the Flight Admin manual and the Cabin Crew Manual.
I would assume it is published in the inflight magazine too.
