Six dials, and what the airframe has taken.
Two pages of instruments, each figure a measurement or nothing.
Six dials, and what is left in the cell.
Ground speed, horizon, altimeter, turn and slip, track, vertical speed. Over the middle dial, the battery in percent: how much flying is left in the device is the one thing the other five cannot say. The time since takeoff, for the logbook, is on the radar.
The horizon rolls with the bank a coordinated turn would need at that speed, because nothing on the board measures a bank. The ball is measured, and it answers the rudder. Nothing here is certified, and it is not an attitude indicator to fly in cloud.
What the airframe has taken.
The fourth page reads the accelerometer and infers nothing from it. The marker says where the wing is now, the box around it says where it has been: the most and the least it has pulled, and how far it has been thrown to each hand.
The peaks belong to this flight and go back to zero when the clock starts. Fore and aft has a strip of its own, because braking and a rough landing are not a wing load.
