You’ll have two scenarios:
1. The pressure reaches equilibrium, or
2. The pressure in the aircraft reaches the maximum and the filling process is halted.

The basic equation would be:

Is anyone making a set of adapters to allow the use of Western hoses with the Yak-52? My hoses are due for replacement soon, and I'd prefer to go with locally available hoses rather than going thru th ...

Could you upload the DXF? I'm considering an instrument panel upgrade, it would really help to be able to get an accurate layout.

Thanks

After several years, the Australian Transport Safety Bureau (ATSB) have finally issued the report for the Yak-52 accident off Brisbane. I've attached a copy to this post.

I guess the investigation ...

I had a little heart-stopping moment on a routine flight yesterday. I was at about 2,000 ft on cruise settings when the engine very briefly cut, and then resumed as if nothing had happened. No warnin ...

How much maintenance is generally required on the Yak-52 pneumatic system, and does the lubrication level play a role?

The background to this is that I shipped my Yak from South Africa to Australia ...

I'd be interested in seeing if there is something available. I've thought of doing one myself, but my aircraft spends too much of its time in maintenance since coming to Australia.

My Yak-52 (1980 model) is currently in for annual inspection, and the shop doing the work has informed me that the wiring is so bad that the aircraft is "unsafe and dangerous". They are insi ...

To give a bit of background to this query, I moved my aircraft from South Africa to Australia a few years ago. I've owned the aircraft since 2003, and as a result have a fair amount of confidence in t ...

Some feedback on the starting problem:
We eventually replaced the solenoid valve, and the starting improved. Still not as good as I'd like it, but on most days I can get a start without having to dra ...

Hi all

I'm having problems starting my Yak-52. Symptoms:
- I can get a normal start, but only if the air pressure is right up over 5 (ie 50). Once the prop is turning, she starts easily.
- Anywhe ...

Hi all

Hi all

We've found some corrosion on the spar caps of my Yak-52, which is going to have to be repaired before further flight.

Is there an official repair manual for the Yak-52, or do most fa ...

Hi all

I've seen a maximum operating altitude for the Yak-52 quoted as 4,000 m (13,000 ft). Obviously this requires pilot oxygen, but is the altitude limitation due to operational procedures, or ...

Hi all

I have one of the older Yak-52s - flush riveted type. Due to a move from one registration to another, I have had to do some running around to determine the actual identity of the aircraft. ...
