Not a high priority for me, but my daughter-in-law is in a flying club and on iPad takes iFly into different aircraft with different cruise speeds, etc. Possibly, as iFly use on iPad becomes more popular this scenario might become more common?
Be nice if she could have separate "load saved profile" or something for at least two aircraft with significantly different specs instead of having to remember to retweak the profile.
Although I fly just one aircraft if there were alternate performance saved profiles I'd probably make one called "slow cruise" "default cruise" and "max cruise.."
