Telstar....true.....not on the 300's !! The 800's are fitted with an Emergency Evacuation Signal.
How do I know this....'cos I've flown this particular aircraft.
Besides...the IRS warning is a steady "horn"....not a high pitch "beeping".
TGIF......
A passenger jet bound for Spain made an emergency evacuation this morning on the runway at Glasgow Airport.
Four people have been taken to hospital and thirteen treated at the scene for shock.
It's thought the panic started when the pilot announced there would be no bar service on the flight.
