OK...so how about adding the runway specific gravity to the ATIS?
This could be the start of a job creation scheme - get some person to go out and take three readings every 30 minutes (they won't block the runways for long).
....but it still comes back to knowing what the tyre pressures are - and are they affected by regional QNH?
How about more job creations...as well as waiting on stand for the refueller, you could all wait for the tyre pressure man to come along with his pocket pressure gauge from Halfords and take the readings.
Another little placard to put on the pedestal with the "cabin secure" card - just for tyre pressures.
Wonder how long it would take on a 747 with..what, is it 18 or 20 wheels?
P.S. .... yes, I'm teasing.
