Before every flight we have perform a preflight check, and for flying VFR (visual flight rules) during daytime there is list of equipment which must exist and must be operational. The entire list is stated in § 91.205, and there is an acronym for simplify our lives: A TOMATO FLAMES. Once filled out it looks like this:
A – airspeed indicator;
T – tachometer for each engine;
O – oil pressure gauge for each engine using pressure system;
M – manifold pressure gauge for each altitude engine;
A – altimeter;
T – temperature gauge for each liquid-cooled engine;
O – oil temperature gauge for each air-cooled engine;
F – fuel gauge indicating the quantity of fuel in each tank;
L – landing gear position indicator (for airplanes with a retractable gear);
A – anticollision lights (for aircraft certificated after March 11, 1996);
M – magnetic direction indicator (e. g. magnetic compass);
E – ELT (emergency locator transmitter);
S – safety belts.
Today I was going to fly commercial maneuvers: chandelles, eights-on-pylons, lazy eights, steep spirals. Constant practice is required for mastering them.
After the first climbing turn the magnetic compass attachment cracked, and the compass hanged on the wires. Actually it is not a big dear near the airport in a good weather, and that particular compass is a total mess with non-reliable indications and blurry glass, but legally this device is compulsory for flying. And anyway it is not safe at all to fly with a heavy metal device hanging in front of your face.
It looks like the airplane will be grounded at least for some hours, so it’s time to study.
