James, 3 more notes -
At KJFK in either Gerard's Fouga Magister, or the Senecall - these are more typical numbers that I referred to initially.
Heading Bug : 249.177
True Heading : 236.009, but every few seconds it jumps to something else and then comes back. Can't click it fast enough to catch the other heading.
Alt hold : 36, unchangeable. This is the most common number - 36 or 36000.
Speed hold : 8246. unchangeable. This is the most common number here - 7246 or 8246.
At KJFK in the KC-135
Heading bug : 249.165
True heading : 235.997 or 275.767, this one jumps just long enough to click and catch the 275.767 - otherwise unchangeable.
Alt hold : 36, unchangeable.
Speed hold : 8245. unchangeable.
