Now when had maiden flight, lets not forget efforts of Ajai Shukla of Business Standards and BROADSWORD.

He was momentous in supporting this project when IAF was hell bent on killing it.

Congratulations.

Now I am awaiting for successful flight of LUH.

Air force had a little interest as the Plane is said be heavy. We can hope that with the passage of time the weight shall decrease. Let us hope that it will be operational soon.

I do not know but Indian airforce had put forward this reason for not Zeroing on HTT-40.
A source will be much appreciated. Besides if you are referring to that time when IAF was desperate to kill HTT-40 then like to say that, that time has passed. Today HTT-40 as BTT is very competitive and on par with Pilatus-PC -7 MK-2 BTT. Its armed version will be in class of super Tucano and KA-1.

#Stringent Swiss end-user restrictions prohibit weaponising the PC-7 Mark II. HAL has armed version in pipeline since inception of this project. Its armed version will be sold to countries like Afghanistan, Iraq, African countries and anyone with requirement for Light attack aircraft.

# Pilatus has no zero zero ejection seat. PC-7 Mk II has ‘zero-60’ ejection seats. HTT-40 has zero -zero ejection seats enabling its pilot in any condition. A critical safety compromise in Pilatus.

#The PC-7 Mark II has an unpressurised cockpit. Meaning masks all the way. Flying at high altitude will be uncomfortable. A critical tactical minus in armed version. HTT-40 has pressurised cockpit.This will allow its pilots comfortably during weapon missions over Himalaya like terrain.

#The PC-7 Mark II does not have ‘in-flight simulation’ permits the instructor in the rear cockpit to electronically simulate instrument failures, training the rookie pilot to handle an emergency. The HTT-40 features “in-flight simulation” that permits an instructor in the rear cockpit to electronically simulate various system failures, training the rookie pilot in the front seat in handling emergencies. Wonder what was IAF smoking then, when they overlooked this critical training minus in Pilatus.

I like this. We must produce the best.

Here is one more good news. Sitara with the redesigned body has quickly recovered in spin recovery test.

It is a great news. By the end of the next decade we shall be making all sort of planes here. HTT 40, Sitara, Hawk, LCA tejas, AMCA, Su 30, FAGFA and bloody what not?

There is also something called HJT-39 CAT in pipeline. HAWK experience will of great help to HAL. Since it is almost certain that IAF won't support this program, in all likelihood it will be HAL funded program. However a CTOBAR version of HJT-39 could be sold to NAVY for training its pilots for fighter conversion.

Oh This is great . it seems to be a version of HJT 36 Sitara. Plane looks awesome and i hope that it will have all capabilities of sitara without the flaws that sitara has.

It's basically a twin engine version of HJT-36 with good percentage of borrowing of avionics and cockpit systems from LCA -T MK-1.

With HAL 25-30 KN turbofan undergoing development there is good chance of this product meeting success in international market as well.

I hope HAL repeats its resilience in HJT-39 as well and must not depend on services for funding (though i feel Navy will definitely support this program, it has requirement for carrier based AJT). HAL should sell it as AJT as well as LCA( not to be confused with Tejas) with full full blown A2A and A2G capability. HAWK production line at HAL will come of great help.

2 x25 KN engine is too much for this small aircraft. HJT 36 run on 17 KN Russian engine. Total 25 KN power should be more than suffice. 2x 25 KN engine will push its T/W ratio well beyond any best fighter plane in the world and it should break the plane if run at full speed. If there are 2 engines they should be 10 to 12 KN engine and the one that HAL prepares the one of 25 KN.

Well they might use de-rated version. But HJT-39 is twin engine jet as evident from scan photo above. HTFE should be flexible enough. Afterall whole purpose behind development of HTFE is to get good hold on its jet trainer segment.

Second possiblity is, HAL might conceive HJT-39 as YAK-130 kind AJT & LAA which uses 2x (~) 25 Kn turbofans, not as one like Combat HAWK.
