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. |

I assume since you refer to the "northern folks" that you are referring to the "Land that Mickey built - SOUTH" as opposed to the "Land that Mickey built - WEST?" Jay |

That was a cool story, Capt. Doug.
I'm just a 100 hour VFR pleasure-flyer, and I know absolutely nothing about jets and such. So, please continue to post this kind of cool stuff! I find it very interesting! Adam N7966L Beech Super III |

Great story. Must be a really cool feeling going from FL330
to touchdown at idle thrust. The company was also happy with the fuel savings..... ; ) "Capt.Doug" wrote in message ...

That was sweet! I'd buy the good Captain a round for that one.
Thanks for the bump -- I missed it the first time around. "Peter MacPherson" wrote in message news:Vc2sd.137670$5K2.43770@attbi_s03... Great story.

Hi NG,
question to the group: Nice story, and obviously very skilled performance, but I always thought jets were supposed to land with about 70-80% power on, to be prepared for a potential go-around? (Because spool-up time from idle would be prohibitive in that case?) thanks, Friedrich ...

Perhaps you are confusing RPM with thrust? The correlation is not linear. Normally the RPM is between 70% to 80% on approach, but the thrust around 20% to 25%. You are correct that normally the engines are somewhat spooled up to provide adequate acceleration if needed. Hence the reason I carried an extra 20 knots of airspeed into the flare when using idle thrust. D. |

(Because spool-up time from idle would be prohibitive in that case?) Perhaps you are confusing RPM with thrust? seems to be the case, as far as the figures are concerned.
