No actually I read somewhere that the 757's windshield is rated to only 313 knots for birdstrike.
As mad scientist notes many aircraft are VMO limited by windscreens.
"We have turbocharged condors here...", well, some of the vultures in India must be on nitrous oxide, then, since there are reports of vulture bird strikes at close to 30,000 ft.
Now bear with me a sec.
VMO is IAS, no?
Now (off the top of my head) 300 KIAS is over 500 KTAS at those altitudes.
And for impacts such as birdstrikes, it's TAS that defines the energy of the impact, not IAS, so the energy is about three times that at sea-level.
Oops.... do we have a problem?
Should we start fitting condors and vultures with TCAS?
