Another topic that has been the focus of intense, emotional, debate on our forum is the issue of exploring the acquisition of Russian and/or Chinese aircraft (assuming, of course, that the Philippine Air Force [PAF] ever gets the budget for it)
The forces of caution have long advocated against it, citing logistical and training issues, since the PAF has been a "Western shop" since its inception.
Recently, two concrete points have recently been raised by this camp:
Artificial horizon design. Although not really a deal breaker, it does add to the things that a pilot must remember. This is probably the weakest of the new arguments. Here's a quote:
In a US/Western type attitude indicator, the airplane "icon" remains steady, fixed against the aircraft's nose/wings alignment. During a roll, the background horizon tilts to reflect the "image" of the actual horizon outside. Same thing with pitch - the horizon line moves up and down to indicate the aircraft nose's vertical pitch. Your photo shows the aircraft performing a 20 degree roll to the right without any nose-up/nose-down. as you can observe, it is the blue/black background that tilted to demonstrate the roll.
In a Russian-type AI, the background horizon will be fixed on the roll axis. yes, the horizon line will move up and down to reflect the pitch (nose-up/nose-down) but when performing a turn, the horizon line remains fixed on the x axis. Instead, the tiny airplane icon will tilt.
Service bulletins. We currently have no information about how well Russian and Chinese aircraft manufacturers issue service bulletins like the one below, and if they even translate these to English.

There are many examples of countries that have diversified their air forces with Western and non-Western aircraft: Pakistan, Malaysia, etc. So these countries have managed to work around these issues.
Does anyone here know how they did it?
Are there any other issues that countries considering diversification should consider?
