LTE ? Vortex ring ? Deadman's Curve ? These aren't ATC issues and you shouldn't let them cloud your judgement. For the record, LTE was invented by Bell to cover-up the bad design of a their tail rotor, vortex ring is also known as settling with power and DC applies to any helicopter which is upto 400ft AGL with little or no airspeed.
There all sorts of eddys and currents around an airfield at low level. For instance, an airfield tends to be in open countryside - so the buildings cause immense turbulence to a smooth airflow going over the countryside. Chuck in some wayward vortices from aircraft and you have soup of distraction for a helicopter pilot trying to hold a hover.
Not much power in hand, unfamiliar surroundings, high tension through worrying about encroaching into the wrong area, rapid fire tower ATC.......and so the soup gets even more distracting.
And suddenly our lowtimer isn't doing the primary job : "keep flying the aircraft" is the mantra.
A busy commercial airport is no place for a low-level, low time student helicopter pilot on a solo - unless they've been there dual before.
Same day, same wx, same turbulence, same helicopter - experienced pilot with airport familiarity. No problem.
