With respect to flight HECA-EHAM, MPH8342 - PH-CKB, planned 02FEB2024-09.10UTC:
On the first OFP page, under FL STEPS: HECA/0360/MOOCE/0240/MASEK/0380 a descent is planned from a comfortable F360 to FL240 at WPT MOOCE (TTLT 0327), then a climb is planned to FL380 at WPT MASEK (TTLT 0343).
Looking at data in a downloadable XML file for this flight, FIR valid levels at WPTs MOOCE & EKSOS are shown as 6000, 8000, …, 22000, 24000. FIR valid levels from MASEK onwards are 26000, 28000, …, 59000, 63000. For WPTs in between EKSOS and MASEK valid levels are shown as 6000, 8000, …, 59000, 63000.
In the German Aeronautics Information Publication (AIP, valid date 25JAN2024, ENR3.2-L-6) for airway L604, restrictions are shown for eastbound flights only between WPTs ANELA and MOOCE (available at FL245 and below). This planned fight was westbound, for which no such restrictions were applicable. I think, the flight could have been planned continuously at F360 (or FL380).
One other remark on this XML file…: where it says “ind_airspeed”, I would say that this number equals Equivalent Airspeed [EAS]; the speed shown on the Primary Flight Display [PFD] would be slightly higher. For instance near WPT RODIS: IAS is calculated as 261 kts in the XML file, the PFD - however - will show 278 kts (Calibrated Airspeed [CAS] for the atmospheric conditions at this WPT). IAS does not show on the LIDO flight log pages, it does however on the DAL format. And I think they are the incorrect lower EAS values.
Kind regards,
Simon
