According to Indian members everything is fine. Yet, the entire world says that Indian pilots aren't trained properly.
I really think it is a combination of factors
1) IAF training standards are poor. They need to admit this. The amount of human led incidents shows this
2) No culture of accountability. When things go wrong, they often get brushed under the carpet, indeed, but not admitting faults (for example denying losses of S-400 radar and Jets) internally how does an organisation learn from mistakes in combat if it does not admit to any? After Balakot in 2019, even though PAF downed an IAF jet, it led us to see where we could have improved, resulting in a lot of the systems, platforms and processes that helped us in May this year. This attitude can partly be explained by Indian culture too
3) Lack of platform standardisation. What made PAF formidable in the 60s and in May was standardisation around common platforms (US in 60s and Chinese/Pak today). This has resulted in synergies around networking, training, tactics, logistics and communications. Pak aligned itself with US initially then China. IAF has throughout its history operated a mix of Soviet/Russian, British, French and now American equipment. That is 4 seperate suppliers with 4 very seperate operating philosophies (Although UK and US very similar). This has implications on basic stuff like data linking, what refuelling tankers you can use, ammunition and missile logsitics, pilot training etc
4) Lack of exposure to foreign systems and training. Although IAF is changing this, traditionally Pak forces (and PAF in particular) were very keen that most officers had some international exposure, this was done through either miltary exchanges, deputation abroad, training at foreign academies or joint exercises. IAF does do this but not to the scale PAF has, and remember PAF is half the size so more officers will be exposed. As an example go check out the past postings of past PAF CAS and compare with all past IAF CAS. Many more of PAF will have some foreign training/learning
