Two drills from Prentice days....first was taught to me by Adam Wojda, not a man to waste time, he said he learned it in the Battle of Britain;
Pre take off:- F F F
Fuel - Fan - Fu...leave (Fuel FULL and ON, Pitch fully FINE, Take off)
Second; I still wake up doing it in a nightmare; it's the procedure in a Prentice (OK, in my Prentice) for a change of frequency as in "Go to Tower, 118 decimal 1" when a mile or two from the threshold.
It had a 4-channel valve/crystal VHF set behind the left-hand seat with a selector for ABCD on the panel. If you had not loaded the crystal you needed pre-flight, you had to....
Reach behind the seat and switch set OFF.
Remove crystal from set, by feel.
Open box of crystals on RH seat, locate new crystal out of 75 of them, remove it.
Put old crystal in box.
Reach behind seat, feel for empty crystal socket, insert new crystal
Remove antenna feeder from socket in set
Insert in antenna socket a 3 ft piece of 2-core wire with a bulb on one end
Switch on set
Select channel with new crystal
With left hand press PTT on column
With right hand unlock and turn the antenna tuner knob for max brightness of bulb
Release PTT and Lock tuner
Remove piece of wire and replace with antenna feeder.
Call "Tower, this is GAOPL, short final".
Pretty standard for Civilian licences.
