Early July two aircraft collided in mid air.
The data from the Tupolev's black box confirms the Pravda reports
The instructions of the Swiss air traffic control contradicted the advice of the
- The British BBC soon reported conclusions of the Swiss:
The Russian pilot made mistakes
- The Russian Pravda reported a completely different story:
Swiss air traffic control was a big mess
air collision prevention system
To my amazement, nobody talks about improving the emergency procedures.
My memories from sailing lessons tell me a simple rule for ships on a collision course:
- It must be possible to prevent such a mid air crash, in spite of troublesome communication in the final seconds.
- Why have an emergency procedure in just one dimension (up, down), where a plane is free to move into three directions?
- Why use a procedure that is such error prone and time consuming?
Things are easier on the water, only 2 dimensions and much lower speeds.
- The one sailing closes tot the wind maintains course.
- The other ship, having superior manoeuvring possibilities, clearly changes course.
Aircraft have 3 dimensions for manoeuvring.
Two are sufficient to avoid a crash.
My proposal, a new rule for a eminent mid air crash:
Both aircraft divert right immediately.
- A simple rule it is.
Misunderstandings between pilots, systems and air traffic control are impossible.
- Both pilots can take action
No waste of valuable seconds on communication and interpretation.
- The system is rather fail proof.
It only fails if
their old course.
