GettyFlight secrets: Pilots never discuss their private life during this part of the flight
Flight secrets have revealed everything from the best travel hacks to advice from flight attendants.
The most secretive part of the plane is the flight recorder, which is used to listen to the cockpit during a flight.
This exists so that in the case of an emergency officials are able to determine what caused any accidents or crash landings.
It has now been revealed that recording devices also have an affect what the pilots can talk about on a flight.

Flight recorders only record the last half hour of cockpit voice data
Most flight recorder boxes, also known as black boxes, record between 30 minutes and two hours of the flight.
According to Quora user Tobias Wolter, this affects what pilots talk about to avoid, as the aviation experts understandably wish to any inflammatory topics being recorded.
He explains, having spoken to a friend who is a German pilot: “Flight recorders only record the last half hour of cockpit voice data.
“This leads to most personal topics being cut short about half an hour before landing, just in case.”
Therefore pilots will never discuss their private life during the last part of the flight to avoid it being heard by their work in extreme circumstances.
Alternatively, the time before the last half an hour is also the best time to listen for any secrets to be heard about their lives.

Black boxes on flights only record a short amount of time to avoid the recorded information being used against the pilots.
Pilot Andrew Hennigan wrote on the website: “Originally the two-hour limit was introduced to overcome objections from pilot's unions that the recordings might be misused by management for purposes other than investigation.“
The limit raised questions after the disappearance of the Malaysia Airlines Flight 370 as to whether the devices should record the entire duration of the flight to be able to fully understand a disaster.
The change could one day come into place, as Hennigan continues: “Now authorities are considering increasing this and using other measures to stop abuse, such as limiting access to the recorded data to official investigators.”

Pilots harbour other secrets from within the cockpit as well.
A pilot hijack sign signifies if the flight is at risk or has been taken over to signal to an airport.
Called squawking, it is a silent message they can send to the ground to alert the ground crew.
A distress code 7500 is used in this case so that air traffic control can take the necessary steps to assist the plane.
