Flying the e190/195 here,
my advices would be:
- for descending, try to be a little bit under the FMS calculated path.
- If you have restrictions "at or above XXXX ft" it is a good habit to make a vertical direct to that position. for example, "5000A" meaning the FMS will calculate the ramp above 5000`. so you lock it on "5000" so the FMS calculates the descent to pass that pos. at exactly 5000`
this avoids you getting there high.
- a good thing is that, above the vertical profile on the MFD, the fms gives you the exact distance from the threshold, considering your entire route. so using this, a 3 to 1 mental calculation is a good thing. if you are at 15000 feet above field elevation at 50 miles of the airport, you are mostly ok. something above that requires your atention.
dont forget this: 200kt, flaps 2, gear down. If you are really high, this should do the trick!
When descending in FMS path, (magenta PTH) make sure you have the speed in your scan flow, the fms disregards speed, so it is easy to have a "high speed" alert.
Anyway, this is an easy to fly acft, very automatized and the workload is really low.
good luck!
