Ortac
Romeo 41 is an Airway over the English Channel from the Channel Islands Control Area to the Solent Control Area. There is a reporting point named ORTAC at southern boundary between Romeo 41 and the Channel Islands Control Zone. Its position is 49° 59' 57N,  2° 0' 18W, which is about 30 miles north-north-east of Alderney.  This is not coincident with the islet named Ortac, but its name is undoubtedly derived from the islet.
