Many SID/STARs have altitude restriction that are ranges. In IF the VNAV altitude will only ahow one end of the range. Are we required to adhere to the altitudes in IF or can we use the range on charts?
Example of issues that can occur:
- SID has a minimum level somewhere. Unless you are a full heavy you are going to clear it by a lot.
- STAR has a maximum level on entry that is above your cruise altitude
- Descent/climb angle using the altitudes in IF are too steep
- Some arrivals have exceptions to certain altitudes if you are planning for a certain approach
