I dunno, it would feel a lot cooler and awesome if the magic was detailed..
Kinda like how Negima! & the Fate series are =D
These titles revolve on Magic but they usually have an in depth explanations of the whys and hows .. I know there are other titles out there that have in depth magic system and not a generic "Kaboom" based one lolz
The theme of this series are like 2 opposites.. Technology & Magic..

I hope there was a bonus or something that can explain how a striker unit works
My guess is that each girls have "Mana" (let's name it that for now..) that will flow and be absorbed by the striker unit instead of the usual Fossil fuel for normal machines.
Maybe if the girl runs out of mana, she could fall out of the sky. How to reload one's mana?
Go eat something and take a rest, or better yet, have fun yuri moments with your love witch.. After waking up you'd be having like 3 drop tanks worth of Mana energy for the mission ahead
How do the girls know their airspeed & altitude?? err... I dunno..
Striker units have a built in Neuro Barometric Altimeter to measure altitude above sea level. The data is then fed into the Witches mind so that they'll have an idea how high they are..
As for the airspeed, the striker's inlets have a sort of Pitot tubes inside that measures the press of air to determine their airspeed. Like the Neuro Barometric altimeter, it feeds data into the Witch's mind..
If this was Sky Girls timeline, It would've been easier since their tech is much modern and have an electronic display called the HUD.. ^
But then again, trusting one's feelings is much better than relying on instruments.. So the Witches fly without any of those..
Thus my senseless bloody theories are nothing
(and obviously this is NOT the Official Canon or anything at all just a fan idea.. Someone who have access on how Strikers really work please correct me hahahaha
)
Sorry, this must be the cause being an Aviation fan.. being spoiled by explanations on how those flying machines work and their bloody procedures ~~
