TIME ERROR TOLERANCE
* Used during RTA calculations to establish a boundary on computed speeds.
* 15 seconds is the default vaule (LSK 1L)
* Allowable entry range at 1L is from 6 to 30 sec. The RTA function attempts to arrive at the RTA wpt within TIME ERROR TOLERANCE of 15 seconds unless another vaule is entered.
* Default value displayed in small font.
* This tolerance value affects only the number of potential speed adjustments when near the RTA wpt.
