Thanks latetonite. So even during high elevation (i.e 7000ft) with TA and TL higher than 10,000 ft my input will stay 250/100 and the VNAV will keep the speed until 17,000ft (STD)?
No, from a 7,000' MSL airfield, in a climb VNAV will accelerate at 10,000 MSL / 3,000 AAL! To avoid this you will have to enter 250/170 or don't use VNAV until happy to accelerate above 250kts.
