A diversion plotter that incorporates a 1:500,000 scale , speed, distance and time calculator and has 10 degree markers & waypoint. Eases mental calculations during the time when the pilot's workloads are at the limits
The DP-1 is aimed at those undertaking a Private Pilot Licence (PPL) or Commercial Pilot Licence (CPL) course and is handy tool for qualified pilots to keep in your flight bag. Taking away the mental calculations during the time when the pilot's workloads are at the limits, the DP-1 is the answer to diversion worries.
The DP-1 is manufactured using durable and flexible plastic allowing, the ruler to mould with the contours of a chart when overlaid on uneven surfaces. The plotter components are printed on the reverse side so that the print is better protected when the pilot removes writing on the front side. Using harsh chemicals to remove writing is not recommended.
The unique feature of the DP-1 is the Windstar. During the flight planning stage a pilot/student will complete the Windstar using the app or web application. The app can be downloaded via the app store searching 'pilot windstar'. Once downloaded no internet connection is required, alternatively use the web service here.
The windstar has 8 boxes, representing a cardinal point. (N,NE,E,SE,S,SW,W,NW). Each box is sub-divided into 2 boxes. The top part of each box is used to insert the calculated ground speed and the second box for correction angle. The correction angle can either by a positive or negative number. These figures are based on the planned wind speed and direction along with the planned cruising speed (TAS), from the app or here.
The DP-1 also combines a standard 1,500:000 nm scale. The scale is strictly for 1/2 mill charts designed to coincide with PPL and CPL training. In addition to this the straight edge of the scale can be used to draw a straight line between two points on a chart.
Below the 1,500:000 scale is a Speed/Distance/Time. The table provides speeds from 70kts to 160kts up to a distance of 40nm. The speeds and distance are usually sufficient for the training aircraft and diversion leg of the skills test. The table is used in conjunction with the Windstar and allows the pilot to quickly provide an accurate ETA as well as required times to chosen checkpoints en-route. Anything outside of this range can be easily interpolated.
10 degree markers on the rule allow the pilot during pre-flight planning to mark denote 10 degree fan line from the departure waypoint. The waypoint stencil in the centre of the compass rose is designed to mark around the departure and destination waypoint
