Re: Safe travel altitude / lowest pressure allowed

it's not really about "currently". For quite a while, the tech version does calculate how long one has to wait before being allowed to ascent to 1.000, 2.000, 3.000 meter or board an aircraft. If this time calculates to zero, you are cleared for ascent. This function is likely to be introduced into the Sport version in near future, too.
Opposit to your proposal, the target height has to selected via the settings menu, then the "stop time" is calculated. Calculating a ceiling height would be very complicated, as with air there is no linear relation between depth/hight and pressure change due to the compressibility of air. Additionally, the air temperature will also effect the pressure-to-height relation. In the current approach, there are 4 distinct pressures stored for each hight selection, each pressure is pre-calculated using the barometric hight formular, with reasonable temperatures and safety margins plugged in.
