I saw a news report stating that on the 8th of this month, Air France flight AF293 (Tokyo to Paris, Boeing 777) deviated from the standard instrument departure procedure after takeoff.

After departing from Runway 34R, the aircraft did not bank immediately as required. Instead, it flew in a straight line at an ultra-low altitude (1,380 meters) directly over the Tokyo Imperial Palace in the city center, only initiating a right turn when commanded by Air Traffic Control.

I went to Flightradar24 to check the flight path for the 8th and confirmed the news report; the flight indeed did not fly the correct procedure.

I continued to check the flight records for the days before and after (the 7th and 9th).

This shows the proper route.

The news did not mention why this occurred, only stating that authorities are investigating the matter. Let’s wait for the investigation results.

I looked at the chart, and it feels the normal route is quite similar to the JYOGA TWO DEPARTURE. I’m posting it here for your reference.

According to the chart, the aircraft should have initiated a turn once it climbed to 700 feet (over 200 meters)…
