Now i'm not sure what "every other second" means.. I meant something like every 30 seconds.
You can fly in unstable wheather, or in small orographic waves, you can fly through slightly colder air, your aircraft will also burn fuel, etc.. and I've noticed , in my experience, that if you don't look at your altitude regularly (at least once a minute), your aircraft is going to climb up/down in a random fashion, even if you're perfectly trimmed to begin with.
You can add altimeter lag and VSI imprecision to complicate the equation.
That's where I will get back to the topic.
You could practise IFR procedures.. if you had an aircraft properly equipped for IFR.
With imprecise instruments, what can you do ?
The aircraft I fly do not have DMEs, they have a VOR, one or none ADF. The gyrocompass has a precision of about 10°.. So you could try to fly IFR approaches in VMC with that but you're gonna have a bad time.
