The perfect approach
It was a beautiful day in land that Mickey built- 76 degrees with full sun
while the northern folks got their first freezing blast of winter. We headed off-shore over the islands of the Caribbean. I was on the second radio talking to old friends and catching up on news from all the islands that I don't get to visit much anymore. Caught up with some old friends on the air-to-air frequencies as well. The flight levels were smooth and the visibilty was excellent. Then it came time for top of descent. This time was going to be sweet. There was no complicated arrival procedure and there was no traffic in front of us. We were number one. The center controller cleared us to decend from FL330 to 11,000' at pilot's discretion. One of the keys to good fuel economy in a jet is to stay high as long as you can and then descend at idle thrust. I looked at our weight, and tailwind. As I slowly pulled the throttles back to idle, the nose slowly dropped to maintain airspeed. I switched from Mach airspeed to indicated airspeed around FL240. I monitored the DME's ratio to the altimeter. It was holding constant. I leveled off at 11,000' and let the airspeed bleed off to 250 KIAS. We switched to the approach controller who cleared us down to 3000' and direct to the outer marker. The power was still at idle, the speedbreaks were still stowed, and the approach was looking good. I called the field in sight from 20 miles out and was cleared for the visual. I pulled the nose up slightly to bleed the speed down to 200 KIAS for the airport traffic area. At 1500' the slats and flaps were extended. Then the gear and the rest of the flaps. The old-timers taught me to carry an extra 20 knots into the flare when doing an idle-thrust landing. That prevents you from developing an excessive sink-rate which prevents the gear from going through the wing. I bled off the extra airspeed and more in the flare. The touchdown was sweet. There was just a hint of a bunny-hop before the ground-spoilers popped, but the runway is so bumpy that the passengers probably didn't notice. Without moving the throttles from idle, I popped the reversers and let it roll to the end of the runway. We rolled onto the taxiway without using the brakes. It was a perfect idle-thrust approach from top-of-descent to the gate. I spent the rest of the day sitting with my crew at a bar on the beach enjoying the little things in life. Over the bar was a television. The folks on the television were surrounded by snow. I bet their day wasn't near as perfect as mine. D. |
