That airport like many that airlines elect to fly aircraft into is fundamentally high risk. It is not a reasonable risk to assume on behalf of the travelling public. The probability of a event and the consequence would in any reasonable analysis lead to upgrading of facilities to assure that MEHT and by association the TCH is safe. It is unreasonable to castigate the crew that are being asked to undertake an approach that is knowingly compromised.
My suggestion to the City is to void insurance on any accident involving a jet aircraft into this airport, and into our favorite scenic spot in the french side of the Caribbean. If we are not going to say no, then perhaps the insurers will step in and say what needs to be said. Perhaps then a PAPI or flight path guidance that will provide an accurate flight path for the crew to at least have a fighting chance.
ICAO puts out glossy documents such as ICAO Doc 9859, the one that says categorically what the airline and regulators and airport are supposed to do to not be a recipient of a lawsuit for wilful negligence or being on the reciving end of a wrongful death suit or proceedings.
