Follow up...

The panel adjacent to the pitot tube warn's "Caution Hot", is that the vent for the forward avionics bays?

Follow up 2....

Is that 'Hot' panel on both sides?

Either the LM FlickR web pages with F-35 photos and /or Code One website will have high quality photos of the pitot tube area so that you can ZOOM in with your browser controls to see the writing.

The Pitot tubes are heated so they can burn off water (condensation) and ice at altitude. This stops the crashes like the B-2 at Guam and A330 over the Atlantic.

They do seem to be conveniently located to rip flesh off of heads.... :shock:

Yes and after landing the pitot tube will likely still be hot for a time however that pitot cover needs to be on as soon as because insects will find it attractive to start nest building and then there bee troubles..... :devil:

....and the occaisionally "newbie" ground crew who hasn't received his "salty" pitot tube "brand-on-the-hand" :shock:

... never saw anyone with "Two" brands! :wink:

I guess this covers it?:

Heat Exchangers
The X-35 had several external heat exchangers. >>>>A nose ram air inlet was incorporated for backup avionics cooling.<<<<< A centerline heat exchanger provided cooling for the hydraulic system. A heat exchanger on the left side supported the environmental control system. The F-35 has two scoops located in the wing/fuselage to provide nacelle bay ventilation. The aircraft also has a scoop located on the top of the right wing-glove to provide air to the fuel/air heat exchanger. A deployable scoop is located on the left-aft fuselage to provide air to the IPP and to the avionics. The F-35 minimizes the need for external scoops by using heat exchangers that are integrated in the engine fan duct. These heat exchangers use engine bypass air as a heat sink.

So the old nose ram air was replaced by some kind of forced air system.....?
