Hi there,
although im in no position to be able to comment on documentation requireed by aircraft, i do know that ANO articles 63 and 64 say that a pilot (or indeed anyone) may not act in a manner that is likely to endnager the aircraft.
Could it not be argued that having an aircraft take off without having a means of knowing in which direction it is flying, is acting negligently, and in a manner that may endanger the aircraft?
Feel free to flame me regarding this point
NB
