No it isn't - TPA (ALTITUDE) is denoted as 1589.
Gila Bend is 789 feet ASL and they want you to fly at a TPA as indicated of 1589' and will use an Altimeter setting (probably got from Phoenix Approach or Prescott FSS - or whoever you have watching over you with Flight Following ) at which you fly at that TPA.
Thatīs what I mean to say. Pattern height is 800, TPA is 1589. I have flown many times to Gila Bend without talking to anybody, often times having to get an altimeter setting from nearby. Thanks for clarifying, I misspoke/mistyped. i fixed my previous post.
and like socal said, not a big deal, you just fly the altitude published.
Using QFE in the US is not practical since at many airports at medium to high altitudes, you wouldnīt be able to set the altimeter to 0.
