Good thing the Pinnacle and American planes had TCAS on them a few months back. MEM center control tried to plant them into each other. American was holding, and the control gave the Pinnacle flight a descent clearance right into the guy.
Yes, but the controller also tried to give them a clearance in conflict with what the TCAS was telling them to do. Even MORE scary.
I like the post Doug made about civilian versus military mentality. Generalization, yes. Close to reality, you betcha. Personally, I try to fall somewhere in the middle. I
want to get my passengers to their destination, safely and on time. If something breaks that would not make the flight unsafe, I'll do my best to find a way to legally allow us to depart without it. I have flown airplanes with the TCAS MELed. It just means you must be more vigilant for see and avoid.
I have only turned down two airplanes in my career. First time was when we were taking an airplane that could carry less fuel on a fairly long flight into forecast thunderstorms. Our AC Inverter was inoperative, therefore we had no windshear detection and no GPWS. We felt it was unsafe to take an airplane that would only permit us to carry minimum fuel reserves into an area of known thunderstorms without GPWS and windshear guidance. Little did we know we'd get a windshear alert in a microburst on final, only to do a go-around
straight into a thunderstorm. We diverted and landed at our alternate with FAA required reserve fuel. If we had taken the previous airplane, we would have not had the windshear escape guidance, and we would have landed with 500 pounds of fuel. About 15 minutes of flying time.
The second time I declined an airplane is when we had a complete electrical system failure during pushback. The airplane did not transfer into "essential" power mode, but rather was in a mode I have never seen. It caused our electrically activated/hydraulically actuated spoilers to deploy. ALL of them. Imagine getting to 500 feet on takeoff and losing all instruments, and having flight/ground spoilers deploy? Maintenance was working on a fix, and I told them not to bother. We weren't flying that airplane.
The fact is, things break. Sometimes they can be consequential, and sometimes they are not. I cannot speak for this Captain, and I will not Monday-morning quarterback his decision. I will say, however, that I have flown airplanes with TCAS on MEL and felt completely safe, even going into Newark. Some of the scariest encounters I have had with other air traffic are gliders/ultralights/small single-engine props who do not have an operating transponder. TCAS is a great help, but it should not override see-and-avoid.
Whether the Captain was right or not in the Gulfstream example, he should never have been fired.
