If i stand correct this means my cruise altitude is FL330 and at waypoint RESIA i need to be at FL290?
When i enter this in my flightplan :
But the waypoint after this point RESIA is again FL330. But in my flightplan Resia is also more or less the top of decent.
Why an altitude constraint from 33 to 29 and then back to 33? Or does it mean do not go lower then FL290? But stay for instance at FL330?
