No Batteries Required
Am I also getting to that stage of my career? What ever happened to:
a. Flying boats
b. Fountain pens, and
c. The Mass in Latin?
I still pull a slide rule out of the nav bag for fuel (and other) calculations.
Good thing is that it requires no batteries, chargers, can be taken through checkpoints without upsetting those who are easily upset, and (the best part) the XOs invariably ask "what is that thing you are playing with?"
Hopefully they are enquiring about the slide rule.
From the JT performance/navigation classes:
TI/60 = D/GS = FBO/FF (just plug them into the C and D scales)
I must be getting to old for this stuff.
