I'd put the question to the airport authority, and through them to the Regulating Authority. Depending on your type of operation perhaps an exemption could be secured, using revised minima. On a wider point.....if the ILS is left switched on... is the airport operator inviting its use and therefore sharing liability in any outcome stemming from its use? Of course in a genuine emergency the availability of the ILS whether monitored or not could be a lifeline......but I'm glad I'm not a lawyer.
