The only place I have ever seen the terms "roll steering" and "pitch steering" was in reference to the bars on an ADI. To those you can add "roll-summed steering," which is how Grumman described the steering commands on the ADI in the A-6. |

Splaperons? Only in Tehachipi... OK, maybe I could have resisted But why? |

Of all the lift devices the Krueger flap is in my opinion the oddest
one. Its hinged at the front and pivots forward into 'lift' position. Stick out your hand, palm down, fingers folded back flat. Now straighten your hand so that your fingers are bent down about 30 degrees from the plane of your palm. You have imitated a Kruger flap. FWIW the L1011 had a neat mode of spoiler operation - with the trailing edge flaps in land (33 degrees) position the wing spoilers were positioned up 8 degrees. Slight movement of the yoke fore or aft from the trimmed position raised or lowered the spoilers effecting a useful change in lift with minimal change in AOA. Made it very easy to stay on a glideslope or maintain a set rate of descent. Walt BJ |

The L-1011 lives on as a launch platform and offers performance superior in both rate of climb and payload, over the B-52. |

Anyone else? You might want to look at the recorded parameters for the DFDR on your 747-400. Sorry, but they don't let me bring home a DFDR. Exactly where would I find a reference to "a spoiler flap in a speedbrake configuration," and in what context? Look it up in CFR14, it is a required data element for digital flight data recorders. |

Exactly where would I find a reference to "a spoiler flap in a speedbrake configuration," and in what context? Also, I just looked through 14CFR Part 121 -- including 121.343, 121.344, and Appendices B and M (the FAA standards for Flight Recorder and DFDR operational parameters) -- and found absolutely no reference to "spoiler flaps" in ANY configuration. Or even "spoiler". Although, anyone familiar with aerodynamic surfaces could use the full nomenclature for the fixed spoiler, or the spoiler flap. |
