NERDS out there?!

Sorry but only real airplane nerds should know this. Anyone know why the "recall/cancel" panel on the 757 has this special shape?

Find the panel, thence the desired button by feel? Probably located on the OH panel near the flight deck door.

Straight in front of the captains seat. Im guessing there is a reason for everything and Id like to know what these guys were thinking when they drew up this thing

It could be 'design for assembly' - if a component *should* only fit one way, design it so it *can* only fit one way. Perhaps it is especially important if the panel features 2 identical buttons, you don't want it fitting upside-down by accident (like the soviet missile with the upside-down sensor recently)

Boeing 757-204 flightdeck instrumentation (image preview: FOT7199)

Nothing special, just shaped to clear one of the panel mounting fasteners.

It does appear from this last photo that there is some sort of securing screw at the top left which is not portrayed in your photo.

Suspicious that Mr Boeing has re-designed the Captains panel securing system but was left with the recalcitrant panels which no longer had to accommodate a screw.

They are still using overhead electrical panels on the 737NG that 'accommodate' the analogue gauges that were installed on the 737-100 and will more than likely be used on the new improved 737MAX!

Waste not want not!

Nerds
There are no nerds in aviation; they're called "total aviation persons".
