WAT TABLE CALCULATIONS (please check for accuracy)

These are my calculations @40 degrees Centigrade (or below) using the tables provided for a Short Field Technique (with Cargo Pod installed). PA’s of 2000’ & 4000’ are there to shown interpolation and provide variations for the possible PA for the day.

lilflyboy reported to me as approximately 5 knots. Never-the-less I have not included a wind component even though it will reduce the figures below.

PA Gd. Roll/50’ in meters dry/grs Tq <1865 By-pass Gd. Roll/50’ ob

8750 lbs

2000 1910/3400 579/1030 x 1.15 x 1.03 x 1.05 720/1281 m

2500 751/1351 m

2750 771/1386 m

3000’ 2100’/3768’ 636/1142 x 1.15 x 1.03 x 1.05 = 791/1420 m

3500’ 827/1489 m

4000’ 2290’/4135’ 694/1253 x 1.15 x 1.03 x 1.05 = 863/1558 m

8300 lbs

2000 1660/2910 503/882 x 1.15 x 1.03 x 1.05 626/1097 m

2500 657/1154 m

2750 672/1183 m

3000’ 1820’/3210’ 552/973 x 1.15 x 1.03 x 1.05 = 687/1211 m

3500’ 717/1268 m

4000’ 1980’/3510’ 600/1064 x 1.15 x 1.03 x 1.05 = 747/1324 m

8525lbs (between the above figures)


2750’ = 722/1285 m

3000’ = 739/1316 m

3500’ = 772/1379 m


Keep in mind that the aircraft (according to the sources I spoke to ) did not have the APE III conversion and therefore had to be 8500 lbs (or less) on arrival at Xakanaka (Landing weight limit).

As above you add 15% (dry/grass), another 3% in case full Torque was not used, another 5% if the Separator was in by-pass.

This is for a Standard C208B. I could not get a hold of a POH for a Van with the APE II conversion.Someone please check these, but these figures indicate that even a standard Van could get out of this strip easily which is listed at 840 meters usable.

Now down to the W&B I guess.
