The USAF's fleet of E-8C JSTARS reconnaissance aircraft were all converted from 707-300 series airliners, some of which had already seen service with a half-dozen airliners before being purchased by the USAF for conversion. Using second-hand airliners wasn't exactly cheap however, as the reported unit cost of one E-8C was still 244.4 million in 1998 US ...

To be sure to not use more runway than available. It is also good to have runway to spare in case take-off has to be aborted. Look at this image as an example from another fighter. Notice the two X-axis. The top MIL is for without afterburner and the bottom FULL AB is with afterburner. Notice how the numbers for the MIL is almost double that of the FULL AB ...

F-15s and F-16s use nitrogen pre-charged hydraulic start systems. There is no 'air' involved. The utility hydraulic system pumps fluid into the two accumulators against the nitrogen side of the chamber. When the handle is pulled for starting, NORMALLY one bottle is opened and the hydraulic fluid is released thru the hydraulic start motor on the JFS. ...

AIM-9 Sidewinder and AIM-120 Scorpion are mounted on LAU-7 or LAU-127/8 launchers, known as "rails". Upon signal from the pilot, the motor fires. The missile goes forward. The umbilical cable connecting the missile to the launcher breaks away as the missile moves forward. As far as how they're held on, there is a spring loaded lock mechanism, that ...

The procedure is no different to if it's not raining unless the rain is heavy enough to impair the visibilty from the receiver aircrafts cockpit. Air to Air refuelling is normally planned to be carried out above cloud but there may be operational reasons to do it elsewhere The terms wet and dry refer to whether fuel is flowing or not. A wet contact is one ...

The gun would not have been fired by accident. The mistake here is that they did not unload all live munitions to make the aircraft safe before functionally testing the weapons system. There are multiple safety interlocks that stop a gun from “just firing”. 1) The undercarriage being down and locked or weight on wheels (WoW) is the first. 2) There will be a ...

As a rough rule of thumb, the speed of a compressor/fan is such that when at high speed (i.e. takeoff), the tip of the blade is going close to Mach 1 (i.e. the circumferential velocity is close to the local speed of sound). Thus, large compressors/fan will spin slowly, and small compressors/fans will spin quickly. If you spin way above Mach 1 (say Mach 2), ...

RPM does not generally fluctuate in flight, or on the ground for that matter. For 'fan' RPM, 100% N1, is somewhere between 2000 to 4000.(aka LP stage) For 'core' RPM, 100% N2, is somewhere between 9000 to 14000.(HP stage) The 3rd spool (IP stage) RPM would be in between the LP and HP nominally around 7000. These are ballpark figures.
