Cockpit Conversation: Alaskan Eagles

Cockpit Conversation: Alaskan Eagles

Okay - after trying to work the HTML in Aviatrix's comments box and getting error messages I bailed. Why Blogger can't provide the same easy link buttons for comments as they do for posts escapes me... anyway ...

What an entertaining blog entry with so many items worth commenting on ... where to begin?

re: Aircraft hitting eagles - I recall an event a few years ago in Alaska or the Pacific NW where a Boeing hit a big salmon during takeoff. Apparently an eagle dropped it during avoidance maneuvres. But when I googled for that item, instead I found this related story - funny.

re: "...Cleary looked at the instruments, which showed things were normal, but he had enough runway left to abort the takeoff and did so." and "..."You could see through the engine," he said. "All the blades were destroyed."

It's amazing what a JT8D engine can absorb and still show normal parameters. I once had a slight jiggle and recovery in the EPR (power) gauge during takeoff roll - wouldn't have even noticed it except for a sharp-eyed FO. The temptation to keep going was there - "It's probably just the gauge..." But because the speed was still just below 80 kts. and the weather was lousy, I rejected the takeoff for further investigation. The engine parameters were still normal after using reverse thrust, then shutting the engine down during taxi-back. Upon arrival at the ramp, maintenance discovered a completely destroyed fan section due to a tire failure. Yikes! So glad we aborted that one.

The newest Airbus?

After taking to the skies with an algae powered plane, EADS has unveiled the first electric powered, fully aerobatic four engine airplane at the Aviation Show in Paris. Based on the tiny twin engine Cri-Cri airplane developed by Michael Colomban in France during the 1970s, the latest aircraft is touted as a technology demonstrator by EADS. And unlike a big A380, the all electric Aerobatic Airplane is merely one seater but incorporates various technologies that include lightweight composite structures that compensate for the additional weight of the batteries, four brushless electric motors with counter-rotating propellers, and considerably low noise to that of thermal propulsion and high energy-density Lithium batteries. With its wingspan of just under 13 feet, plane has a flight time, as per company claims, of up to 30 minutes at 110 km/h, 15 minutes of autonomous aerobatics at speeds reaching up to 250 km/h, and a climb rate of approximately 5.3 m/sec.
