Planning an Assigned Area Task

A certain amount of planning is required to judge the weather conditions, decide what cross-country speed you think you can achieve and set a target distance to fly into each area.

The Waypoint Sector screen below, will allow you to move your target points in each area to adjust your expected total task distance, and based on your expected task speed from your MC value, plan how far to go into each sector.

In general, you want to make sure you go deep enough into the first area to ensure you don’t arrive early if the weather improves, and plan to be starting your final glide not before the minimum task time.

Waypoint Sector Screen

This screen can be accessed by tapping the direction arrow box on Final Glide screen, top left corner on Moving Map screen, (both only when active task, goes to active waypoint) and View button on Task Waypoint Edit screen. The left example above is for a PDA that has an unchangable silkscreen button area. The right example is from a PDA that has a Dynamic Input Area (DIA). In this case, the additional area normally occupied by the silkscreen button and input area is lowered. The task-related information is then moved down into this area to provide better map clarity.

Pressing the Calendar or Phone buttons will display the previous or next waypoints. You cannot display a waypoint before the active waypoint if a task is active.

This screen zooms in on the waypoint sector and gives you information on the total task distance and estimated time on task (TOT) based on your average speed. If you have set a minimum task time in the Task Rules screen and the predicted time on task is shorter than this, the TOT field will be hightlight.

If you are flying an active task, this speed and TOT is based on your MC setting and your average speed on the task so far. Also displayed is the estimated time of arrival (ETA) at the active waypoint.

If you are not viewing the active task, then the screen calculates your task speed using your MC setting for the expected thermal strength. You can use this to set your expected thermal strength and therefore average task speed. The ETA has changed to an estimated time elapsed (ETE) calculation and gives the expected time elapsed to reach the waypoint following the task.

Once the task is active, but you are still on the ground, you can change the MC value, and enter manually the expected wind. This allows you to look at the ETE at each turnpoint, and expected finish time. you can adjust the target point in the sectors to give you the optimum task plan.

Note: if your MC setting is zero, N/A will appear in the TOT and ETA/ETE fields as it is not possible to stay airbourne with a thermal strength of zero!

If an area waypoint is displayed, you can move the target point within the area by tapping the 4 edges of the map area. The map scale and map orientation keys work as per the Moving Map screen.

You also have a Min and Max button, which will move your target point to the min or max distance in the sector.

If you are currently in-flight, viewing the active area, and your glider is in the area, tapping the centre of the screen moves your target point to the current glider position.

Tapping the centre of the screen (or the Center button if displayed) when you are not viewing the active area will move your target point to the centre of the area. If you are in the active area, this will move the target to your current position.

Changing the target point changes the task distance and the expected TOT and ETA/ETE. This allows you to do some task planning on a fixed time task and determine how far to fly into each sector.
