I noticed that some of the Block60 versions don't have Pitot Tubes.

Block 60 hasn't got Pitot tube instead it using integrated multi function probes.

Block 60 hasn't got Pitot tube instead it using integrated multi function probes.

No difference in functions, only different in name. All aircrafts need raw air data. Pitot is basically rammed air through a tube. Static is basically air pressure. Lower altitude has a denser atmosphere and would exert a greater pressure, or 'weight', on an object. The hole at the end of a pitot probe that is facing the airstream is pitot air. On the side of the probe could be several much smaller holes, but at least one, and they are for static air, or 'weight' of the atmosphere. Placing the probe directly in front of the aircraft, as in at the tip of the radome, give the most direct and accurate of all air data, but because the probe is metal, there would be some minor interference with the radar system. Moving the probe to be along side the fuselage would require some redesign, mounting and recalibration of the entire air data system. Not technically difficult.

Am going to clarify this air data probe thingy a bit more...

The problem here is more about terminology than functions. For the images above of the F-111's intake, what is pointed out as a 'Local Mach Probe' is nothing more than a pitot-static probe, shaped slightly different and mounted in another location. But notice that the probes are facing into the airstream. Ram (pitot) and static air here are slightly different in velocity and pressure than the ones from the main probe at the radome's tip. The reason the F-111 uses them for the engines is to control inlet air velocity. Mach air is not good for long for any jet engine. For the F-111, that green and long pointy thing right in front of the intake is called a 'spike' and it actually expand, or 'blossom', narrowing the total intake mouth and slowing down inlet air velocity to subsonic. The inlet air, or spike, control system could not function without those pitot-static probes.

So no matter who call what these probes mounted where, basically they are pitot-static sensors. Let no one mislead the readers with fanciful sales brochures terminologies.

Thanks for your useful inputs, as always.
Great.

Differentiate between block 50 and 60...?

Differentiate between block 50 and 60...?

50 - 60 = -10
Can I have my degree now?

Wrong....

50 + 60=110

Anyone have pictures of PAF Block 52? Other than the ceremony pictures.

here you go:

i hope you will like it.
