"direction of approach" is a correct and usable phrase in written English.
It is often used when discussing the way in which someone or something is approaching a particular target or goal. Example: The pilot carefully evaluated the direction of approach before attempting to land the plane in the unexpected storm.
The main defense was concentrated in the direction of approach, where there were often two or three lines of advance fortifications.
Retinal speed did not correlate well with the actual risk of predation because it confounded a predator's direction of approach with its speed and proximity.
As for Midway -- in which the Americans enjoyed knowledge of "enemy objective, timing, strength, direction of approach, launch position," and scored an impressive victory -- he insists that it was not a pure intelligence victory, as some have contended, but a victory in which chance played an equally important role.
A careful review of the geometry of the engagement will reveal that even a moderately skewed off-frontal direction of approach will drastically reduce the chances that fragments from the Iron Dome warhead could be sprayed onto the warhead of the artillery rocket.
Although vision can in principle provide instant information on a predator's position, direction of approach and identity, prey animals that face fast predators have to respond so early (close to the limits of detection) that visual cues are unreliable predictors of actual risk.
Our structure also reveals that the inhibitor approaches the active-site cleft from the opposite side of the crossover loop as compared to the direction of approach of ubiquitin's C-terminal tail, thereby occupying the P1′ (leaving group) site, a binding site perhaps used by the unknown C-terminal extension of ubiquitin in the actual in vivo substrate(s) of UCHL1.
A new method of estimating the direction of approaching waves is presented and it is shown that this method correctly reproduces the analytic solution.
Under such empirical analysis, the zero-adjusted inverse Gaussian distribution is appropriate to reflect the distributional characteristics of crash rates and provide a new direction of approaches in the field of crash data analyses.
The two rectangular coordinate system (x, y, z) and (X, Y, Z ZZ indicates the direction of approaching meteor) constrains the geographical and meteoric trajectory location in space, respectively.
In order to evaluate this possibility, the direction of approaching bats was divided into four even sectors and the time to contact was evaluated for each sector separately.
