On selection of up, the gear is hydraulically driven flat as the doors open and then retracted.
My books say that the bogeys are driven from forward wheel up to forward wheel down.
While the logic works off the RAD ALT. the transition from Ground to AIR mode happens when the tilt is taken out of the main gear trucks.
So you're saying that it's Rad Alt for Air to Ground, and tilt for Ground to Air?
Can you confirm that it is truck tilt and not the landing gear beam load sensors which give air/ground data to the AP and TMCS for the go-around function? Ref Boeing 777 AMM D&O 32-09-00. Or is it a combination of both?
I'm having trouble understanding the relationship between the PSEU cards and the WOW cards.
Thanks.
