2012年7月5日 · The King Air F90 and F90-1 were produced between 1979 and 1985. The F90s were faster than their predecessors, thanks to a more powerful version of the Pratt & Whitney PT6 engine. The F90 actually is a “hybrid” King Air in that it combines the fuselage and wings of the King Air E90 with the T-tail of the King Air 200.

2009年8月1日 · The King Air F90 is a fuel-efficient version, thanks in part to the Pratt & Whitney engines with improved turbine blades that extract more power from the engine. At 300 mph true air speed, it burns less than 70 gallons per hour.

打开vscode，创建一个文件，后缀名命名为.f90（Fortran程序的后缀），先编一个最基础的hello world程序吧，名字就叫hello.f90。 在.f90文件中输入下面代码： ok，这个时候再在终端中输入gfortran语句，调用gfortran编译器对.f90文件进行编译。 语法为“gfortran -g f90文件的地址 -o 输出文件地址”。 但是我一开始并没有成功，而是在vs的终端中报了个这个错误： 上网百度了一下，用了这个大神的回答（解决无法将“xxxx”项识别为 cmdlet、函数、脚本文件或可运行程序的名称 …

The F90-1 was built with redesigned engine cowlings, upgraded PT6A-135A engines, hydraulic landing gear, and triple-fed electrical bus. Only 33 were built by the time production on the model was terminated in 1985.

2008年9月30日 · With its two PT6A-135 engines, the King Air F90 climbs so well that owner Ron Zagami often files for low-20,000-foot cruise levels, no matter how short the leg. The broad T-tail enables smoother airflow and enhanced pitch control.

Those few* F90-1s that Beechcraft made are highly sought-after variants that outright perform. But, they don’t come with upgraded avionics, a fancy interior and much lower airframe hours found in newer aircraft.

2019年1月1日 · Considered by many to be the finest of the smaller 90-series Beechcraft King Airs, the F90 is a typical “parts-bin airplane.” It uses the E90 fuselage and wings merged with the towering T-tail of the larger King Air 200. It also added 400 more horsepower than the C90 of the time, earning it the same “Super King Air” badge as the 200.

The KingAir F90, produced only between 1979 and 1985, is the model just above the go-to entry-level C90. A total of 236 F90s and F90-1s were built, with 137 of them still on the FAA registry. For those of you keeping score, that’s 203 F90s and 33 F90-1s with 58% still officially around.

F90-1 - superseded the F90; offered improved performance by offering PT6A-135A engines (885 shaft horsepower at max takeoff power, compared to 850 power for the -135). H90 - a trainer version of the U-21, designated the T-44A Pegasus.

2021年6月8日 · Also, the F90 was the first King Air to use the company’s completely new, state-of-the-art, 28 VDC multi-bus electrical system. The circuitry featured five separate buses, automatic load shedding and solid-state current sensors that provided protection against ground faults (electrical shorts) and quickly isolated a faulty bus, thereby ...
