A real inconvenience at remote northern locations such as Canada/Alaska where normal de-ice facilities don't exist. Expensive solutions are very high and expensive and incovenient tall, mobile stairs stuctures or powered, vertical lifts to enable access for de-icing.
And the only real large turboprop options are T-tail such as the ATR and DHC-8.
