Hi mates !
Today I made a flight to Lisbon, and on the STAR chart I found 2 altitude restrictions for each legs: "MAX xxx" and "MHA yyy" where MHA was always smaller than MAX... obviously

I had to reprogram the FMC because I thought the altitudes there are not correct, but then I was confused what to enter. So what is MHA altitude ? I cant find any info on it.
Thanks.
