Hi JPJP,
Thanks for TipToe Visual Chart.
Therefore: at 1900 feet, the aircraft is 400 feet high, 5 miles from the runway.
Even if they were 400 feet higher than the 3 deg slope at 5nm, then their approach path is still only 3.75 degs. (Marseille Provence RW 31R has ILS GP set at 4 degs).
It should not be a problem for crews ahead of their aircraft.
