I've lived in both camps. Rotary first and now the fixed side. And let me tell you: I far more enjoy the job I'm in now. I flew the S76 for almost 8 years. And in interesting places! Thailand, Philippines to mention a couple and oh Karratha. W.A. And, I'm sure that's where I met and flew with Gordy (Ne). Karatha.. out and back 99% VMC very very boring! But the social life was a laugh. Songkhla, Thailand. Again out and back same old. Doing the shuttles first thing from rig to rig was the fun side. Could do up to 20 or so landings in a hour! If I remember right. The food on the BQP (Initially French) was beautiful. Until nationalised then not so good. Then came the joining of Lloyd and CHC. Time to move on. Manila.. Now this was fun and very interesting flying especially when the Monsoon season was on. IFR in and out of Manila using the ILS. Full speed 130kts down to about 2 miles. Refueling in Busuanga Island was a challange when the weather was down. And flying with really really nice guys.... This was my exit and over to the the Fixed Wing World.
After obtaining an Jar A licence. I was lucky enough to secure a First Officer position straight onto the Boeing 767. I thought, Being an experience 5000 hrs Heli pilot I would have little difficulty in making the mark!! So wrong was I!! I had to work my arse off just to keep up! Flying from A to B: boring!! Absolutely no way!! There were times I didn't even get chance to look out of the window (In the cruise). Doing an NDB approach in Mexico in CB conditions!! In my opinion is much more challenging than getting onto a rig in the monsoon conditions.
Now, I'm in the left seat of my B767 (Capt) and really still enjoy the job. So, In retrospect. I would not change a thing. I really enjoyed the rotary world (at the time) and enjoy the Airline flying more.
There are MANY Airline pilots who used to fly helicopters BUT not many, if any, Helicopter pilots whom used to be Airline pilots!!!
