If still too high (by 2000 ft above the platform, approaching the FAP - i.e. unrecoverable - let's imagine), the unfortunate decision to do a 360 would have you complete the full circle at 4000 below the target altitude. The obstacle clearance on the intermediate segment is 500 ft. Useless trick, that gets you nowhere but in trouble.

Give it one more read including the post I was replying to. I think you'll find we're in a perfect agreement, cześć.

I have seen a lot of armchair experts on here before but I think this one takes the cookie. We know absolutely nothing about what went on in the kitchen (cockpit). In contrast to a steep spiral at 230 kts, thrust idle, flaps 5, speed brake out night IMC (as some may imagine).. it could just as well have been smooth sailing at 180 kts, flaps 5, vertical speed at 1000 fpm draging it in with thrust on a moon bright night in obstacle protected airspace. As for reporting it... CHIRPing whatever that entails... give me a break. Disconnect and enjoy the fun of flying. |

I knew somebody would rip into me for that. Pull ya head in, Giggity. I never said I pass all responsibility for terrain clearance to ATC when they are radar-vectoring me. We also don't have access to radar terrain charts. Given the gung-ho attitude of some here "she'll be right, no hills around here that I can see", that's probably a good idea.

If you're doing you own thing though, as it appears here, John Wayneing an orbit below the 25nm MSA because you're high and in the area of the holding pattern is not on. You're either in the Hold or your not. Can't see the relevance of "500sqm"... The relevance was that 500sqm is a very large area, there will be many times that weather might appear inside one of these 25NM/90deg arcs. In that case, i'd assume most pilots would request a deviation to one side or another after first checking whether it was safe (terrain wise) and then passing that request onto ATC. ATC will either approve or deny that request based on the terrain, airspace, traffic etc. Using Flight Detents RNAV STAR 28 chart, if there was stationary weather at ETPAL i'd genuinely like to know what you'd do? Would your only option be to request direct to the hold and stay 8300ft till you get there, then descent to 6000ft in the hold and fly the approach after a couple of laps of the hold (assuming there was no other compatible procedure, for whatever reason)? I don't mean to be obtuse but I can see this as the only solution, at which point ATC will tell you to stay at 8300ft and wait a further 20 minutes so the other aircraft can pass underneath you. In reality, every time I've flown this approach - although it's been a while - it was via that RNAV transition and ATC just issue speeds for spacing. We've simply planned to fly the thing conservatively and don't end up with this dilemma. |

Sorry but I wouldn't like the idea of diving in such a mountainous area at 2000 ft/min or more for a glide slope which is already pretty steep, being busy with speed and configuration change... And I suppose that while orbiting you are still able to stop your descent at the desired altitude. ;)

It's your turn, alright...
