To quantify head-up transition behavior with and without a flightpath type head-up display, eight rated B-727 pilots each flew 31 manual and coupled approaches in a simulator with B-727 dynamics and collimated model board external scene. Data were also obtained on the roll played by the head-up display in the coupled-to-manual transition. Various wind shears, low visibilities, and ceilings were tested along with unexpected misalignment between the runway and head-up display symbology. The symbolic format used was a conformal scene. Every pilot except one stayed head-up, flying with the display after descending below the ceiling. Without the display and as altitude decreased, the number of lookups from the instrument panel decreased and the duration of each one increased. No large differences in mean number or duration of transitions up or down were found during the head-up display runs comparing the no-misalignment with the lateral instrument landing system offset misalignment runs. The head-up display led to fewer transitions after the pilot made a decision to land or execute a missed approach. Without the display, pilots generally waited until they had descended below the ceiling to look outside the first time, but with it several pilots looked down at their panel at relatively high altitudes (if they looked down at all). Manual takeover of control was rapid and smooth both with and without the display which permitted smoother engine power changes.

1Luck of the Dudley Grahams

By Alice Calhoun Haines

The Luck of the Dudley Grahams is the story of the four Graham children and their recently widowed mother, trying to make ends meet by taking boarders into their somewhat eccentric home, as told by 17-year-old Elizabeth to her diary. She chronicles their struggles with the boarders, housekeeping on a very tight budget, and the adventures of her three younger siblings. If the category existed at the time, this would be more of young adult novel than a children's book, as Elizabeth has her moments of angst and worry about herself, her family, and their future. - Summary by Colleen McMahon
