Hi friends: Strange that the 737s came late to the Mexican "flag carriers". MEXICANA never flew ones and Aero Mexico started using 737 in 2003 (737-700). But various Mexican low cost airlines used 737s even the "Jurasic" 200 and the "Clasic" 300. Many tourists were carried by them from MMMX to the tourist centers. I flew with Nova Air, Magnicharters and Aviacsa to and from Cancun. en.wikipedia.org/wiki/Nova_Airen.wikipedia.org/wiki/Magnichartersen.wikipedia.org/wiki/Aviacsa All were 737-200 ADV. All started from MMMX with a "full house" and I presume with tanks halffull, having a one hour reserve arriving at MMUN. At least that one can assume using the FS9 simulations. Kind regards |

Think the "clean wing" and tri-engine configuration of the (larger) B727 .... and "that" (clean wing) of the DC-9 too .... were better suited to some of Mexico's hot and high environments such as Mexico City in particular. During the very late 1990's and early 2000's AVIACSA acquired a number of the originally mid-1980's delivered AIR NEW ZEALAND JT8D-15 powered B732 ADV's. Think the earlier D-7 and D-9 powered B732's might have struggled a bit within some of Mexico's airport environment/s unless powered upgraded (an "expensive" proposition) or weight restricted .... the latter then impacting operational economy of course .... whereas the D-15 (and D-17/A in particular) powered variants might have resulted slightly more positive difference for operators like AVIACSA. Just "a guess" only Mark C AKL/NZ |

Hi friends:
Seems Mexicanas and AeroMexico's decisions were well done when they were taken. The tourist boom of Cancun started late in the Seventies and transport to the "Riviera Maya" was a business opportunity for the new "low-cost airlines". For them the 737-200 (JT8D-15 upward) were better suited in costs, ease of operation and maintenance. The 200s at that time became available secondhand in big numbers.
In my picture above the Continental 737-200 with JT8D-9 engines was full but with half full tanks. The APAN 5 departure could be flown but only with a low climb rate marginal for that departure.
Kind regards

Just as well he's not using a "JT8D-7" powered B732 then As the assigned "weight and engine thrust" of each B732 aircraft type is specific to each version offered by us/HJG .... then .... using a "D-7" powered version (with its lower thrust rating) one will find the ROC (at/near MGW) a bit lower still and one might not be able to go up much beyond the virtual FL250/FL280 (initially) without exceeding engine limitations .... and even then only after one's burned off a lot of virtual fuel/weight too. This (as Walter's discovering) is "one of" the advantages of offering aircraft/engine type/and weight specific configurations as we/HJG have always done over the past 23 years .... since 2000 in fact. What we offer gives one a good idea of how the B732 developed, and improved, over time. No 2 configurations we offer are ever identical or fly precisely the same way either (if flown properly/as recommended). It's better to develop "THIS WAY". It "does" make for a better/more comprehensive B732 offering (in this particular case) .... albeit one that's "slightly more complex" too .... otherwise what we offer would be no different from anything that's been previously done and there'd be no point in our offering what we do. "A LOT" of FDE work was applied to this particular project .... since some of the original data was "way out to hell". The FDE's for what we/HJG offer are "VASTLY SUPERIOR" .... despite certain performance parameters still not being entirely accurate "due to the limitations of FS itself", but, FS at best is always "a delicate balance of truth versus a bit of bull-shi-yet and jellybeans" anyway.

Hi Mark:
Tried today also the APAN departure with a DC-9 10 with the JT8D-1 engines. AND it flies out from MMMX even full and at 25 dig centigrade better than the Boeing 737-200 with the D-7 engine. Both were the original HJG simulations
Kind regards
Walter
