AS 420- LOFT Paper Crew: Jason and Shubhanu 1. What did you encounter during the LOFT? We experienced No4 Engine Failure at V R . Had to shut down the engine and trim the rudder as we were at a slow speed, almost at V MCA . We decided to continue to the destination instead of diverting back to the airport as we had three remaining engines to support the flight. 2. What decisions did you make and why? Also, what communications would have been necessary in such a real-world scenario? We decided to Shutdown engine No 4, trim it to maintain directional control, and maintain a positive control of the aircraft. We had three remaining engines, which would be sufficient to help us continue to our destination of MIA instead of MCO as that gets the passengers closer to the destination, while landing at an airport which could provide adequate maintenance and services for the passengers to reach by busses, or another aircraft. In a real-world scenario, we would need to communicate with the dispatcher, and the ATC controllers- let them know that we need priority as we have one engine less than planned. The dispatcher would also be helpful to arrange services at Miami, even before arrival. 3. What did you learn from the LOFT experience? CRM- Crew Resource Management is key to an emergency. We were not overwhelmed by the emergency as we divided work and discussed everything that was to be done. We also noted that the climb rate decreased a lot as Quito is located at a high altitude as is, and one can only imagine the performance loss on a high-density altitude day. The onboard radar helped to avoid CFIT and helped us maintain situational awareness. It was important to have the knowledge from Exercise 7 that helped configure the airplane for the loss of an engine. Another, thing we learned was we had to reset the trim anytime a climb was initiated, or the power was changed. It would be wise to declare an emergency however, with four engines, we still had enough performance to continue to our destination, this shows how important redundancy in aircraft is. 4. What suggestions can you offer to improve the LOFT? a. The LOFT scenario was relatively easy as we expected an engine failure. However, if there were to be another engine failure a diversion back to Quito would be important, as the performance would decrease more than 80%. b. The flight could be arranged for a shorted period to match the class time. Maybe from Quito to Cali or Caracas. That could be achieve for the length of the class. c. Another way to really test the pilot skills would be to have unexpected emergencies and problems which keeps it fun and also allows the pilots to engage in High level thinking.
