Rules and general ramblings
Posted: Sat Aug 08, 2020 2:39 pm
I was watching a post about Gabriela Island accident and of course the normal thread drift and guys like BP are all about black and white and no grey allowed so instead of throwing it out there with all the little finger pointing school kids I will field my thoughts here.
I know we have had the discussion of "it's legal" as opposed to the real question "is it safe" but using the logic of the rulees it's OK to fudge numbers like male/female weights to make it legal and the list of such bullshit goes on. So getting to my little operational idiosyncrasies which I pose as questions.
First if you have a radalt where do you set it on a precision approach (ILS,RNAV) I set at 100 feet for the D/H and the reason behind that is it's not part of cat1 or LVP instrument requirement and it only gives proper information(cat2 or cat3 minimums) over flat ground which only guarantee is the runway.
Second on a RNAV with an LPV approach but you are not LPV authorised where do you set your minimums, for me LPV (and yes radalt at 100 ft) with the thought that as long as you have non-LPV approach limits who can tell and really who cares. Approach bans are based on vis so why does a D/H matter as more than a point of reference. I have seen so many times where aircraft with all the toys missing approaches in stratus ceilings with unlimited vis and the aircraft clearly visible from the ground as the gear is coming up. I am not suggesting everyone goes around busting minimums but if we venture into the world of grey and think and plan your moves missions can get a better completion rate and still be very safe.
I always got irritated with pilots who are constantly throwing out "what if" scenarios trying to choreograph all emergencies into a set of rules. I always turned to and simply told them to learn their aircraft and drills because every emergency is a surprise with its own special circumstance. To put it more bluntly "fly the fucking airplane"
Chuck started the zero zero landing thing. I think we all should have the confidence to drive it down to the ground if there is no other option. Chuck is likely aware of this but back in the day a pig boat driver did that off an NDB and landed zero zero in Hudson's Bay (PQ side) and tracked back to shore using the NDB. Very high pucker factor and certainly extensive "local knowledge" but did it non precision.
Nothing less professional than not keeping the needles centred until the flare unless briefed. I would duck the GS a little to touch down earlier for short runways or slippery conditions. On runways with a surplus always at GS TD point. Ducking the GS adds risk, especially in a big aircraft but can be done safely if you use all the information available such as PAPI's and GS.
