thank you, installed-

it happens just at the end of first component, windows 10 1709

I usually program flightplan without star and arr runway, i watch at charts altitude of the last waypoint, p.e: LEMD SID PINAR UN870 PONEN UT600 CASPE STAR LEBL in the 3 stars of LEBL (1,2,3) chart determine FL25 ot 26 at CASPE, i put that alt restriction and sid n DEPARTURE runway and vnav is totally avalaible. When u are close to T/D (in case that ur cruise level is above that alt rest) u can input star and arrival without extrange altitude resuts. hope it helps Enrique

"The lowest “at” altitude restriction if no arrival procedure is entered. " I think you can determine the E/D by asigning an alt restriction to last waypoint.

Top Of Descent (T/D) The point where the cruise phase changes to the descent phase is the top of descent. The T/D point is shown on the map as a green open circle with the label T/D. T/D is calculated from an end of descent (E/D) point. Intermediate T/D points show on the map as green open circles with the label T/D–XXXXX (altitude). Intermediate T/D points exist when path segments between altitude restricted waypoints produce a level path segment. The intermediate T/D point shows where the descent will resume. FLT MGT NAV Sec. 6.11 Page 20 737 Rev. 11/15/02 #41 Continental Flight Manual End of Descent (E/D) The FMC calculates a descent path based on airspeed restrictions, altitude restrictions and the end of descent (E/D) point. The E/D point is shown on the map as a green open circle with the label E/D. The E/D is the last of the following, which is not preceded by a lateral discontinuity: · The runway threshold for approaches with a runway waypoint on the RTE LEGS page, or · The missed approach point for approaches not showing a runway waypoint on the RTE LEGS page, or · The lowest “at” altitude restriction if no arrival procedure is entered. Entering an instrument arrival procedure provides an E/D point. If there is no E/D point, FMC predictions assume a computed profile to 1000 feet above the destination field elevation at a position, which varies according to selection of arrival procedures. The FMC provides a slowdown profile for approach. VNAV path descent is not available if there is no E/D point.
