'No speed'
If you ask a pilot why it is normal to reduce to 250kts below FL100 s/he will no doubt respond that it is to assist ATC with the management of traffic and, coupled with windshield heat, to help reduce the effect of a bird strike.
On departure when given the option by air traffic of 'no speed' pilots smile, think of the possible saving in time, and happily select VNAV speed.
What about the possibility of a bird strike?
This never seems to be considered yet is potentially just as likely as on the descent.
Is this a case of doing what we are trained and taught, rather than what would appear to be common sense?
