  1. 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
  2. VNAV not calculated when ARR Runway not entered

    "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.
  3. VNAV not calculated when ARR Runway not entered

    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.
