As a general rule, any safety cross-check should be proportional to the hazard.
The yielding pilot's cross-check is based upon the worst-case assumption that the flight lead could initiate action at any time.
With a good cross-check established, pilots must be able to recognize collision vectors.
Since 1986 we have organized or taken part in Mooney viscosity cross-checks in collaboration with a substantial number of laboratories.
In figure 5 the results of the three cross-checks for these target functions are presented as bar charts.
In two cross-checks remeasurement by Bayer of samples prepared by the participants was carried out on one Mooney instrument only; this gave "theoretical" improvement factors of 3.
Because all of the squ ares covered by the left part have trivial cross-check sets, we need not consider those squares when traversing the dawg--we need only to know the maximum size of the left part.
We can express the backtracking search as a recursive procedure ExtendRight: ExtendRight (PartialWord, node N in dawg, square) = if square is vacant then If N is a terminal node then LegalMove (PartialWord) for each edge E out of N if the letter l labeling edge E is in our rack and l is in the cross-check set of square then remove a tile l from the rack let N' be the node reached by following edge E let next-square be the square to the right of square ExtendRight (PartialWord .
The NFU has been in touch with Natural England and they say that these cross-checks
have to be done.
The Racing Post has also undertaken further cross-checks
of greyhound SPs in tandem with the Press Association.
The Travelocity Business mid-office system, based on Sabre QIK technology, automatically cross-checks
the combined cost of the separate segments to ensure they do not exceed any company-specific cost thresholds that can be pre-configured within the system.
All values above 1,000 ppb were re-analysed and cross-checks
were done by fire assay with gravimetric finish and rejects re-analysed by fire assay with AA finish.
