PERF Button / CRZ ALT missing

[d3ca.deaf]

Hi, just wondering why the PERF button is missing at the 146 FMS? Its there in the operations manual - but not the final product.
I think we need the PERF page to set up a correct CRZ ALT, to have some altitudes in the flight plan. Unfortunately, CRZ ALT will not be imported via world map / simbrief.

I know there is no LNAV and maybe it's not totally necessary, but display of the altitude data shouldn't be a big of a deal? I'm sure the WT FMS is capable of. ;)

@d3ca-deaf You should still be able to get there from the Index page because I know I've seen it.

The PERF page wasn't included at release as there is no VNAV integration so it'd just be a repeat of what's available from the performance charts and speeds card, but we'll look into adding it in a future update if people would like it just for reference purposes.
