Time difference will not give you any relative information,you need time taken to complete...but good analysis
are you working in DWBI 
?the idea is - LCA rolls out when its ready.. how quickly is a new LCA ready is the analysis.Time difference will not give you any relative information,you need time taken to complete...but good analysis
definitely something has changed in SP 10 - they probably added/replaced LRUs?
Some modifications planned for Mk 1A
Must have been incorporated on SP 10
Other wise there was no reason for this long delay
The LRU s for MK 1 A are to be made more maintenance friendly

Does this mean that this is the New Kaveri engine built
After the French help and modifications
Are they expecting the private player to do altitude test?

ADE has issued a tender for Tejas MKIA DFCC Chassis Assembly. The tender opens by end august and first unit to be supplied in 3 months from date of contract
The fabrication of the chassis has to be carried out in Three Stages, based on the following Terms &
Conditions:
1) FIRST UNIT - PROTOTYPE UNIT (01 No.)
• The first prototype unit shall be fabricated using the first set of chassis component drawings released
and approved by ADE.
• The first prototype unit shall be delivered within 03 months from the date of placement of
order/contract.
• Depending on the outcome of the fabricated components and results of the preliminary assembly
tests and checks, the second set of drawings will be released with modifications (if required).
2) SECOND UNIT - QUALIFICATION TEST (QT) UNIT (01 No.)
• The second unit, which will be the Qualification Test (QT) unit, shall be fabricated from the modified
set of drawings approved and released by ADE.
• The QT unit shall be delivered within 03 months from the date of receipt of the modified drawings. T0
for the QT unit starts from the date of receipt of the modified drawings from ADE.
• Based on the Qualification Tests of the QT unit carried out in ADE in collaboration BEL Bangalore,
the third set of components drawings will be released (if required).
3) THIRD, FOURTH & FIFTH UNITS - FLIGHT WORTHY UNITS (03 Nos.)
• 03 numbers of Flight Worthy units shall be fabricated from the final modified set of drawings
approved and released by ADE. T0 for these three units starts from the date of receipt of the
modified drawings from ADE.
• These units shall be delivered together within 04 months from the date of receipt of the final modified
drawings.
• These final flights worthy units will accepted based on the mechanical inspection reports and
Qualification Tests results carried out in ADE in collaboration BEL Bangalore.
ADE has the right to short-close the demand, in case the design requirement of fins with 0.4mm or lesser
thickness (as mentioned in Annexure 'A') is not achieved even after the Second Unit (QT Unit) is fabricated.
4) Detailed drawings shall be obtained from ADE against Non Disclosure Agreement for details refer
1.1, Part 1(A) of RFP at Page No. 3.
Mk1A coming ☺☺☺

Assuming DFCC stands for digital flight control computer.
Assuming DFCC stands for digital flight control computer.
This seems to be a tender for the box which will be used in the new computer.
this is th first step in developing integrated modular avionics architecture.
Progress in Production of Tejas Aircraft
Two contracts were signed between IAF & Hindustan Aeronautics Limited (HAL) for procurement of (i) 20 Initial Operational Clearance (IOC) standard aircraft on 31st March 2006 to be completed by December 2011 and (ii) 20 Final Operational Clearance (FOC) standard aircraft on 23rd December 2010 to be completed by 2016.
Out of total 20 IOC aircraft (16 fighters and 4 trainers), 9 fighters have been delivered by HAL to IAF till date. The production of remaining 11 IOC aircraft (7 fighter + 4 trainer) are taken up at HAL. The aircraft is currently capable of undertaking Air Defence Operations and conventional ground attack with heavy bombs is feasible.
Production for 20 FOC aircraft, will be taken up after FOC clearance by Aeronautical Development Agency (ADA) for which current target is December, 2018.
In order to fast track the production of Light Combat Aircraft (LCA) Tejas and to achieve FOC clearance given by ADA, the following initiatives have been taken:-
•
For ramping up production capacity from existing 8 aircraft to 16 aircraft per annum, Government of India (GoI) has sanctioned Rs.1381.04 Crore in March, 2017.
•
Enhancing production rate of LCA Tejas primarily through outsourcing of major modules to private partners with HAL moving to the role of lead integrator.
•
Establishment of second line for structural and equipping activities at Aircraft Division, HAL.
•
Increase in number of jigs for Front fuselage, Centre fuselage, Rear fuselage and Wings.
•
Reduction in manufacturing cycle time through improved Supply Chain Management, learning and augmentation of manpower.
•
Modularization of electrical looms for reduction of cycle time of aircraft looming.
Besides, 40 aircraft (20 IOC & 20 FOC), Defence Acquisition Council (DAC) has cleared acquisition of 83 LCA Mk1A for IAF for which quotation has been submitted by HAL.
Further, in order to bolster the fighter squadron strength, Government of India has also planned to manufacture fighter aircraft through Strategic Partnership model.
This information was given by Raksha Rajya Mantri Dr. Subhash Bhamre in a written reply to Dr. Banda Prakash in Rajya Sabha today.

You were saying only air refuelling is pending in PDF
Gun trial abandoned for FOC ? Or got over ..?
If abandoned ...
I remember Vstol talking about altering the location of GUN to forward position to get extra pylon and few other things like front landing gear changes to shed weight..

Gun has been delinked from FOC. It can even be certified for production versions when fully ready.
Yeah, it will help if that hardpoint is freed up.
