No problem understanding that, did it twice in the last year. Tirupati, India, holding overhead at FL310 due to an unNOTAM'd airport closure, procedural control, eventually cleared to descend from FL 310. Once, in contact with the tower, Chennai sent over to the tower for the approach clearance. See the airspace division?
Second time, entered holding at PTRO at FL 240 overhead the field, "leg length and direction at pilot's discretion". Two airliners shuttled down in the hold, below us, until each was given a cruise clearance into uncontrolled airspace. Once down to FL 160, Oakland OAC issued our cruise clearance. Took about 40 minutes with all the SELCALs and HF clearances.
So, yes, I and rest of us fully understand flying airplanes. A wee dram of patience and less condescension would allow us all to learn something here at TechLog, the web's best source of practical knowledge.
