I was hoping for some insight on this, perhaps also from pilots who have used AOA indicators. This because I assume that an AOA indicator is the only means to get at least an idea of how much lift is being produced.
The real question: In a crosswind, during the roll, it is friction from the tyres that keeps the aircraft tracking down the runway, since you can't crab before becoming airborne. If the wing starts to produce lift during the takeoff roll, that friction will reduce.
Is that lift significant, or is it minimal (on a tricycle-gear aircraft)? In other words, does the surface friction decrease by lots, or is it relatively unaffected throughout the ground roll?
As a follow-on, how does ground effect influence the lift that is generated during ground roll at essentially a fixed AOA until rotation?
I'm interested primarily in the business jet side of the house, takeoff weights between 20 and 35 tons, but would also like to know what the answers might be for airliners (Airbus, Boeing). I was going to exclude the aircraft that - with all due respect - "sit funny" on the ground such as the CRJ900 or the G280, but then thought that fuselage attitude might not be directly related to AOA.
