Incorrect, Cap'n. :ugh: :=
Use attitude to adjust airspeed. Use power to adjust rate of descent. |

Amazing as it may seem, sorry, Lead Balloon, I am going along with my old mate Bloggsie here, a bit against the grain, but there you go. "Attitude controls rate of climb and descent, power controls airspeed" always works, as I have gone into some (including historic) detail on other threads on this subject. "Attitude controls airspeed, power controls rate of climb and descent" is really applicable to the era of glide approaches being the normal approach. However, just to redeem myself, I will ask if Bloggsie has actually read said well known book, where at one point the whole concept of fixing the "point of no relative movement" at the desired aim point and maintaining the target airspeed with power, is the real point of the exercise. For a real discussion, how many of you have heard of, and practice, "minimum ground speed" (Yes!! ground speed, not a mistake) approaches ---- where the IAS on approach varies quite widely. Tootle pip!! |

No Bloggsie, a very long time ago we would calculate a "Minimum Ground Speed" and fly it within limits of Vref -0/+ 20 if I remember rightly. In most cases it worked quite well. Then it morphed into "Reference Ground Speed".

Rojer Must, I recall a skygod mate referring to the "Reference" one a couple a decades back... Lead Balloon's got a GPS in his machine, maybe you could introduce him to RGS? Might help him stay on speed in the bumps while he's pulling the nose up to get back on slope... :E

All,
My mistake, I did mean "reference ground speed". Originally developed in a collaboration between the long gone Flying Tigers cargo airline and Qantas, and a really effective defense against wind sheer. Actually, in a real glide approach ie engine dead, one uses the stick/pitch to control the flight path or else... Tootle pip!! |
Well, who'd 'ave thunk it?? Talk about a statement of the bleeding obvious. |
Originally developed in a collaboration between the long gone Flying Tigers cargo airline Any idea what magazine that was published in? |
Centaurus,
That's the one, don't remember his name now, but as you probably know, there were a number of occasions (and continue to be) of "landings" short of the runway, where shear is/was probably a factor. "Autothrottle" is NOT the answer in severe cases, with the obvious connotations for current day accepted SOP. Ground speed awareness is also a major help in combating downbursts. Tootle pip!! |
You guys going "pitch for slope" on a glide approach better keep your eye on speed as well! ;)
|
May I suggest that if a pilot is carrying 50 knots extra down final because he expects to lose it all in a windshear, he is an idiot! And what's more, since he got in, he unwittingly "encouraged" the 727 crew to try the same.
Tank, when you hear the strangled cat, raise the nose no more! :) |

Buffers are good - I've done a hill top landing in a fixed wing where the aircraft has gone from 'top of the white' (max flap) on final, to a full stall landed in under two seconds. A big surprise after over 10 years of operations to the strip, though the wind were just right on the day to give a perfect little high intensity roll wave at the threashold to catch me. |

See the following wonderful story about him. A lot of initial reading but you will quickly see his story and the newspaper cutting about him. You Gotcher Handsfull Buddy! |
Thanks to the truck and Chieftain drivers for creating the thread and as always giving rise to thread drift. Interesting read Centaurus
