After the assembly is installed there will be functional checks involving rigging, flapping, and balance. functional check evaluates only a single system within the entire aircraft. This is not to imply that all systems in the aircraft must have a functional check to complete an operational check on the aircraft.
Cut back shrubs grown primarily for their foliage, such as barberry and burning bush, almost anytime except in late autumn. New growth that starts after late-season pruning won't harden off properly before winter. If you want to do major pruning, it's best to cut the shrub back when it is dormant in winter.
When should we fertilize, prune, plant, cut back, harvest, etc? Here are a few important âtimingâ answers. Prune. The best time to prune most plants is when they are dormant in the early or late winter. Before trees leaf out, you can see the branch structure and decide which limbs to remove and which to save. When pruning to thin out a tree, it is important to maintain the natural shape by carefully selecting tall, outlying branches for removal. When you prune during dormancy the trees stored resources are still in the roots and large stems. After pruning, trees can concentrate those resources in the remaining branches for a good growth flush.
