I don’t know about how those guys train or stay current. But to practice these types of failures do they do any sim training like some others do?? We all talk about engine out on take off and what to do about it.
TD;DR: Yes they practice them. More than likely in a simulator, maybe in an airplane.
Let me preface all this with although I flew mostly large, 4-engine airplanes in the Air Force for 25 years, I retired back in 2016 so some of this information may have changed in the past few years. Also, I didn’t fly C-130s, so although the AF would like to think they are standardized across airframes and across commands, they aren’t. I flew KC-135s, and even though its been years since we transitioned from SAC to MAC, now AMC the tanker worlds always held onto some SAC-isms and still to this day does things differently than airframes that were MAC/AMC (C-5s, C-141s, C-17s).
Speaking from the KC-135 world, we would have a monthly requirement to perform takeoffs with a simulated engine failure (we could pull an engine to idle after 200’ AGL), and to do simulated engine out landings and engine out go-arounds. The would also be evaluated on our recurrent checkrides. These items for the longest time were done in the airplane under the supervision of an Instructor Pilot. In addition to the OEI flying, Instructors were also allowed to demonstrate other failures in the aircraft (jammed stabilizer approaches and landings, OEI approaches with hydraulic failure to the rudder, etc.)
With this kind of training, I would say pilots were mostly proficient in their flying and handling of flying Emergency Procedures. We would still go into the simulator to practice other EPs that couldn’t safely be done in the airplane.
Several years ago (maybe 10 or so), the Air Force decreed, under the guise of safety that all EP training would be done in the simulator. All engine out procedures, all failure simulations, etc. There was an exception made for units that didn’t have a simulator collocated at their base. Luckily, our base didn’t have a simulator, so we were able to continue to train in the aircraft. For those pilots who were at a base with a simulator, all they could do in the plane were four engine operating approaches, landings, and go-arounds.
Personally, I think the training is not as good as it is in the plane. The simulators are not near what a full, Level-D sim is capable of and the sims that we had really didn’t replicate the airplane with the fidelity that I would have thought was necessary to really get a feel for the jet.
So, how much training and practice did these guys have in engine out flying? I don’t know, but I bet it was less than they would have had 20 years ago.
