Do any airlines have Braille emergency checklists? In reading the report into the crash of UPS Flight 6, I noticed that one of the items of feedback from pilots in a simulated inflight-fire scenario utilising a smoke-filled simulator was (page 287 of the report):


  In the thickest smoke, only Braille will help. What bigger font does to you, if there is any "break" in the smoke, it allows you to see more letters (group), therefore part of words. From that you can deduct what the action on the checklist is for the next step.


(Emphasis added.)

Which makes sense, as Braille, unlike most scripts, is read by touch rather than by sight, and is, thus, unaffected by limited or nonexistent cockpit visibility, while visual scripts, even with large, simple glyphs, have their legibility severely impaired by a smoky cockpit (in dense smoke, the pilot(s) essentially have to wait to do anything until the smoke momentarily lifts), and are completely useless in a zero-visibility environment.

With this in mind, do any airlines (passenger and/or cargo) have Braille checklists for use in situations of severely degraded cockpit visibility (such as a cockpit filled to the brim with dense black smoke)?
It would be counter productive


It takes time to learn (especially touch reading)
It takes time to keep proficient 


This is time spent on a skill useless for >99,999999% of flights

This is time NOT spent on more useful safety trainings

This wouldn't work anyway


It would be very slow to find the correct checklist then read it
If the aircraft is shaking, it would hinder your speed/prevent your from reading
You have to take your hands of from other controls to read


There is better alternatives

Simply having a recording/speech synthesis/speech command would solve it.

This one is a killer
