Maybe you can input the altitudes and temperature for the approach that was used by the accident aircraft and see what descent angle is required.

Thanks,

The crew used 3.5 degrees. That might explain why they were low on approach if 3.3 degrees was the angle that should have been used. As we know, there was no crosscheck of altitude versus distance and their company procedures manual(used instead of Airbus issued manuals) did not require them to crosscheck altitude versus distance.

It would be interesting to see the airlines formula table(or whatever it is) that was used to come up with 3.5 degrees as the crew apparently followed this table properly..
