H 1 - remember the time scale. Mid 70s to date is 35 years. A lot of people here were not born then. What mid/light twins were available? Bo 105, S76, Bell 212,A 109, Dauphin or Bell 222. With an original idea to have SWAT capability the B105 was too small and the S76 and B212 too large. No room in the back of 109 and no headroom in Dauphin.
After a couple of low hovers we operated normally at 1,000ft where you could see all you needed, use the loudhailer, and generally not create too much noise-what gets people is not the DB level but the beat, and avoid the F/W passing overhead.
AB -The prime task was the major consideration above running costs. We could easily get airborne in 2 minutes as in the B105. As a work environment it was fast (150kts initially) with a beautiful ride, low vibration, manoeuvrable and quiet. I once spent 9.5 hours flying one day with no discomfort.
Unfortunately the LTS101 let the aircraft down.
