gert57 0 Posted March 23, 2014 Share Posted March 23, 2014 Hi all, I have a flying problem and I hope somebody can help me. Problem is this: When I climb or descend the twotter I want to have a constant IAS and a constant rate of descend/ascend. I do this: When I want to descend, 1. reduce torque pressure e.g. 40 to 30, 2. Pitch down to abt 1000 ft/min vertical speed. 3 When speed settles, adjust trim so yoke can go back in neutral position. BUT IAS and vert speed don't stay constant. So it's very difficult FOR ME to get a stabilzed approach. Maybe I am doing something wrong. Pease help this newbie twotter pilot. Thanks!!

Finn 873 Posted March 23, 2014 Share Posted March 23, 2014 You cannot ahve both a cosnatnt IAS and verticalspeed. The Twin Otter does not have autothrottle, this means that when IAS Hold is engaged, then the autopilot adjusts the speed by increasin/decreasing pitch. When enggaged while trimmed for the wanted IAS, pitch will stabilise quite quickly, but as You climb or descend and get into less/more dense air, Your vertical speed will surely change. Maybe You confuses IAS with the autothrottles of larger airlinser where You can define both a set speed as well as vertical speed. Finn Link to comment Share on other sites More sharing options...
gert57 0 Posted March 24, 2014 Author Share Posted March 24, 2014 Hi Finn, thanks for the reply. But I wasn't talking about autopilot flying. My question was on hand flying. When doing that I can't get a stabilized descent. I want to have the ability to fly by hand, because if you are flying vfr to small airstrips using the autopilot isn't allways an option. Sorry I made myself insufficientlly clear. I hope you or somebody else (maybe RL pilot) can help me. Greetings, Gert Link to comment Share on other sites More sharing options...
Finn 873 Posted March 24, 2014 Share Posted March 24, 2014 Ah - Ok I will do a testflight myself later.... Finn Link to comment Share on other sites More sharing options...
