Hi mtoroshango
No "AM" had a throttle and when the computer didnt work (more often than not) it was just a twist grip.
I remember taking "AY" up to 17500' when I was on my own, between Isfahan and Zagross because the Flight Manual said the max alt for a Jet ranger was 20,000'. Running out of puff (the aircraft, not me because we had oxygen) at 17500', I chickened out when I saw a DC6 on the airways beneath me.
Anyone at Zagross remember the ski lift that we built for recreation on the slope near the base. The pulley wheel was underslung by the 204 at the top of the slope and Schlumberger loaned us a wire line engine which was converted into a ski tow.
