Narrative:

There is a new ZOB/cle LOA which took effect jan/xa/99. This letter is unsafe. It diminishes service to the user by imposing static in trail restrs on turboprop aircraft. There is an overflt shelf south of cleveland which will become a shooting gallery for en route aircraft. There is a loss of terminal airspace to the northwest which will increase coordination between facilities and preclude fanning of jet and propeller departures. Propeller separation has increased 100% to 10 mi in trail. The consensus is that this letter creates an unsafe working environment and poses a danger to the flying public.
