After on and off research lasting a year, I have finally found the information I needed. I decided to look up hard numbers after Zest Air had two accidents at this airports within 6 months.
I have found after much digging through conflicting numbers that Caticlan Airport has a runway length of 2,938 feet. http://business.inquirer.net/money/t...240715/Caticlan-flight-rules-eased
Airlines and Aircraft:
Official takeoff distances are at 15 celcius. Caticlan is 30 celcius, meaning air is less dense, requiring a longer distance for takeoff. These quoted distances are supposed to include safety margins such as an engine failure situation.
SEAIR uses the Dornier 328 aircraft to Caticlan. The President personally claims this aircraft can operate at MTOW using a runway of just 2,460 feet. http://www.flyseair.com/node/168 This is definitely not the case. At MTOW, the Do328 needs 3,570ft according to an approved maintenance contractor for this aircraft. http://www.328support.de/en/328/328-prop.php Dornier itself no longer exists so I cannot dig up their numbers. Even if the Do328 is likely to be 1,200kgs under full weights from Caticlan to Manila, it’s doubtful whether the takeoff distance decreases by 638 feet. SEAIR was allowed to continue flying to Caticlan even with runway restrictions in place because “the planes were smaller”. This is a misconception. The Do328 is a “high-speed” turboprop. To allow for the high speed, the aircraft needs to have less drag/lift which means it needs long runway for its size!
Zest uses the MA-60 aircraft which stands out because it is an extremely heavy aircraft for the size. This 56-seat aircraft’s OEW is even heavier than the 72-seat ATR-72-500 aircraft that Cebu Pacific uses http://www.atraircraft.com/public/at...products.php?aid=506&pid=28706 and http://www.flightglobal.com/pdfarchive/view/2001/2001%20-%202982.html The MA-60 is also 1,500kgs heavier when empty than PAL Express’ 50-seat Q300 aircraft. http://www.bombardier.com/en/aerospa...ducts/commercial-aircraft/q-series Information is vague about this aircraft but an official-looking PDF quotes a 3,600 feet required for a fully loaded takeoff. http://www.chinaga.com/UserFiles/MA60Aircraft.pdf This probably means the MA-60 would safely manage to takeoff with a limited number of passengers, say 25, instead of the full 56 and they are supposed to be restricted like this on this route. That said, they had 55 passengers when they overran in June. http://www.philstar.com/Article.aspx?articleid=481030
PAL Express’ Q300 aircraft has a full-weight takeoff run of 3,865 feet. This would mean considerable reductions in weight (by limiting number of passengers) to shorten the safe takeoff distance by over 800 feet, as required for this airport.
Cebu Pacific’s ATR-72 aircraft requires 4,232 feet of runway. This means even more weight-shedding is needed. After the obvious overloading by Zest, it is obvious there is lax regulation and I really question if PAL or Cebu Pacific really does the weight shedding. I am therefore curious if PR and 5J really enforce this.
Of course, the old Asian Spirit actually used a suitable aircraft in the past, the Dash-7 to Caticlan. This aircraft however was notoriously expensive to operate.
