Metro's a fun airplane to fly. I've been single pilot metro for a year now and have really loved it. As for the type training: it's not that bad. The systems air somewhat straight forward. Some of the systems are hard to believe-- ex. fuel crossflow. There's no pump. Just a valve you open and slip the airplane to transfer. Easy enough, until you start thinking of how uncomfortable that had to be for passengers back in the day. Other system that's confusing is on the metro III and newer-- the computer used for starting it. Push the button and it starts- makes sense. Try and figure out what's actually happening through that start sequence can be a challenge (how the actual system works). Probably the worst system on the airplane is the hydralic nose wheel steering. It's dangerous. A lot of metro pilots have taken their plane through the weeds when that system fails. Lord knows you wouldn't design the nose wheel to fail straight-- you design it to fail hard left. Why hard left?? If you're on top of it, you can save it (I've had 1-- tough to deal with though). I think if that happened the first 100 hours flying alone you'd need your fair share of luck to not take it off the runway. You still need some luck no matter when that system fails.
Emergencies can be a handful. The company I fly for has 10 metros-- none of which have an autopilot. You have an emergency and you're doing everything. Not a whole lot of emergencies go on though, thank the lord. Hydralic failures, pressurization not working, and every once in awhile a wing overheat seem to be the standards. Oh yeah... and taking a bird through the engine is the other fear-- that seems to happen about once a year for us.
Learning the flows are the most important. If you aren't taught a specific flow make your own. This airplane almost requires a flow-- if you don't have one, it'll take you forever to do anything. The cockpit is not the most organized. Deice-- half the switches are up and half are down to have everything on. Why? I don't know. The bleeds are on the other side under the copilot's yoke. Not the end of the world, but sure not in an easy place. The gen and battery switches are behind your yoke-- why? You can't read the switch-- you have to learn what's what.
Fun airplane. I really enjoy it. Just don't be afraid to manhandle the thing. It's like flying a mack truck. It's the least responsive airplane I've flown. and it doesn't trim for crap.
