Chart doesn't go high enough--what about FL410-FL470. I'm figuring' that the lowered risk of mid-air and being on top of a lot of weather compensates the odds.
Here is the complete chart..
Radiation increases DRAMATICALLY with increasing altitude! ( concorde.. )
that's why in the jar ops it's compulsory to carry radiation measuring equipment onboard if you fly very high
(b) 1. an operator shall not operate an aeroplane above 15 000 m (49 000 ft) unless the equipment specified in
OPS 1.680(a)(1) is serviceable, or the procedure prescribed in OPS 1.680(a)(2) is complied with.
2. the commander or the pilot to whom conduct of the flight has been delegated shall initiate a descent as soon as
practicable when the limit values of cosmic radiation dose rate specified in the Operations Manual are exceeded.
and btw yes with increased latitude there is a lot more radiation! go on the cari website and do it by yourself..
ps: everytime I go fly I chk this:
