Yep. It's 700 AGL for the Transition floor at Many. Sorry for the typo. (corrected) Thanks.

MDA (Minimum Descent Alttitude) is the lowest a pilot may descend on an approach until reaching the MAP. If he then has the airport/runway environment in sight he may continue to descend and land.flyguy wrote:...KAY - GAY qweshun 1 WHAT IS "MDA"?

Those people are nuts.
My experiences of instrument flight in un-controlled airspace mostly precede the present identification of airspace. What is now termed " Class G" used to be quite common in large areas of West Texas as late as the early '70's. It sometimes reached up as high as 14'K MSL. (There was no instrument clearances available in those areas at all, and it was legal, although with the associated hazards of traffic/obstacles, to fly IFR in there. I don't know of any such airspace today in large areas, except that found below 1200' AGL... of course obstacles are a definite hazard below 1200'!) At that time I had a job flying pipeline patrol along defined routes, along which I had a thorough knowlege of obstacles and along which, and at altitudes which, the potential for traffic conflicts were virtually "zero." Many times the pipeline was patrolled by patrol pilots in visibilities approaching zero along such routes. I believe that the practice was considered suicidal by anyone not familiar with the pipeline, but hundreds of miles of such pipelines were regularly inspected by such techniques by many patrol pilots, especially along marshland/coastal areas (long before helicopter operations were common there) and in remote areas of West Texas/Oklahoma. I'd not even consider doing it these days, and the practice did not take into consideration the rule about separation from people and property... it would doubtless be indefensible.a respected friend wrote: Under most circumstances, IFR in uncontrolled airspace should be limited to 1. a published IFR approach where the MDA happens to penetrate Class G. 2. an IFR departure from an airport with Class G airspace where you have to climb (typically on an obstacle departure procedure) to Class E airspace where the IFR clearance takes effect. Pilots need to know that the biggest safety implication under 1 and 2 is there is no IFR separation in Class G airspace and VFR traffic can be there legally with visibilities as low as 1 mile. Obstacle clearance can be assured by adhering to published IFR approaches and DPs. There are circumstances where IFR in Class G can be done safely by professionals with carefully planned procedures but most GA operators do not do this often. When making any IFR approach, the term "Flight Visibility" or the visibility determined by the pilot in the cockpit is the most critical factor in safely completing it. This is the visibility you refer to that a ground observer has no way of knowing. It is during this phase of the approach that the pilot determines safe height and course to the runway without the assistance of minimums. ... I spent 24 years flying for a large west coast regional airline and was a check airman for 20 of those years. Even though we have good wx out here, we have low IFR approaches all the time (coast/summer and valley/winter). Our flight department trained and stressed flight visibility always. We were taught and tested to identify flight visibility references and to continually monitor our ability to control the airplanes safely. If we lost these references it was an automatic missed approach. They never encouraged us to do "look/see" or "duck under" approaches and I can honestly say the majority of our guys would hit MDA or DH and do it by the book. We never had an accident. ... I have been shocked at the attitude of (some) pilots who boast about "always getting in" having "special" approaches" etc. I have seen several fatal accidents where pilots have clearly strayed from published routes/minimums. ... Don't forget ... to "stick to the straight and narrow". We'll live longer. By the way, best of the holidays to you.
