We don't have a lot of direct descriptions, but the one I recall was in HotQ, and it make it sound like you do a continuous transition (at least on the way down).quite possibly a cat wrote:I stand corrected on the impellers!
There are a lot of bands, but you don't just go straight from N-space to the delta bands. You go N-space to Lowest Alpha band. Similarly you go from the lowest Alpha band to N-space.
4 minutes to drop across the Gamma bands is too quick for a hyper-generator to recharge from a transition and let you move again (that's on the order of 10 minutes for a DB, much less a CA like Fearless or a multi-megaton freighter like the ones transitioning with her).Honor of the Queen wrote:“Ready for translation, aye,” Chief Killian replied, and the helmsman’s hand hovered over the manual override, just in case the astrogator’s computers dropped the ball, while Honor leaned back to watch.
“Mark!” DuMorne said crisply, and the normally inaudible hum of Fearless’s hyper generator became a basso growl.
Honor swallowed against a sudden ripple of nausea as the visual display altered abruptly. The endlessly shifting patterns of hyper space were no longer slow; they flickered, jumping about like poorly executed animation, and her readouts flashed steadily downward as the entire convoy plummeted “down” the hyper space gradient.
Fearless hit the gamma wall, and her Warshawski sails bled transit energy like an azure forest fire. Her velocity dropped almost instantly from .3 C to a mere nine percent of light-speed, and Honor’s stomach heaved as her inner ear rebelled against a speed loss the rest of her senses couldn’t even detect. DuMorne’s calculations had allowed for the energy bleed, and their translation gradient steepened even further as their velocity fell. They hit the beta wall four minutes later, and Honor winced again—less violently this time—as their velocity bled down to less than two percent of light-speed. The visual display was a fierce chaos of heaving light as the convoy fell straight “down” across a “distance” which had no physical existence, and then they hit the alpha bands and flashed across them to the n-space wall like a comet.
Now we don't know if ascending is similarly continuous, but I suspect it is. (That may not have been the case hundreds of years before when hyper travel was first invented, but now continuous transition seems likely to be the norm)
You are presumably visible, and vulnerable, in the bands as you drop through, but at presumably less than 4 minutes to cross the entire Alpha bands a waiting enemy wouldn't seem to have long to try to take a shot at you... (especially if they have to be in the same subband to see and attack you)
Still it wouldn't be too hard to camp out in the bands that ships are most likely to use approaching the terminus. that could let you bag some unsuspecting victims until word gets out and ships being using evasive routings.
