Every aircraft requires a longer runway in wet conditions. What is your point?
Quite right. We've all heard during our travels:
"Ladies and gentlemen, this is the captain. Because a light drizzle fell on our destination runway while we were enroute and because the runway is still damp, I regret to inform you that we will have divert to our alternate airport and remain there until such time that the runway of our destination airport becomes, once again, dry. We sincerely regret the inconvenience this may cause to your travel plans and we appreciate your patience. This was an act of God over which Air Stupid obviously has no control and we hope that you appreciate that this measure is taken in the name of safety, which at Air Stupid is priority number one. We thank you, once again, for making Air Stupid part of your travel plans"
Sir, on the aircraft I fly, the difference in landing distance between a dry and a wet runway at maximum braking effort and at maximum landing weight is 370 meters, so about 1,200 feet. The minimum length runways we are dispatched to always includes the wet runway provision, precisely so that we never have make such a ridiculous announcement as the one above. How can one dispatch an aircraft to an airport thousands of miles away on the prayer that the destination runway will have to be dry at the time of arrival in order for the aircraft to be able to land?
Boeing, to be able to meet its target runway length, even after that target had been changed from 3,000 to 3,500 feet, had to imagine that little scheme where the 3,500 foot runways it was dispatched to always needed to have 400 foot
under runs and
over runs (which real 3,500 foot runways do not have) and then they decided not to include any wet runway provisions, such as is done for all aircraft of the world.
You can call me a liar all you want: I have provided US Government documentation for every statement I have made on this forum.
The Boeing C-17 is a fantastic Strategic Aircraft with some Tactical capabilities, just like the Ilyushin IL-76. Each of these two aircraft has advantages over the other, and each has qualities that the other does not have.
Aircraft can be upgraded and often are. Here is the picture of the cockpit of a C-141B
Here is the same aircraft with an upgraded cockpit:
When an airframe still has potential left in it, it can be upgraded in engines and avionics at a much lesser cost than replacing it with new expensive aircraft. The original 1963 C-141A was stretched, and provided with in flight-refuelling which became the C-141B and some of those were converted to full glass cockpit into the C-141C. All C-141B were converted and upgraded C-141A and all C-141Cs were upgraded C-141Bs.
The C-130 Hercules was first flown in 1953. It was continuously upgraded and improved over the years and is still in production today with the C-130J. Many Hercules aircraft were not manufactured in their final version but were upgraded from earlier versions.
In helicopters, the US has the CH-47 Chinook which was introduced in 1962. The most common version on US Army inventory now is the CH-47D. Almost all the CH-47Ds were not new builds but were converted, upgraded and overhauled CH-47As, Bs and Cs built in the sixties and seventies. Most new glass cockpit CH-47Fs are upgraded CH-47Ds which themselves were upgraded earlier from CH-47As, Bs and Cs.
With all this in mind, why is it that 1980s era IL-76s are considered ancient and of need of retirement? The only flying IL-76MF, the stretched version prototype, was converted by Ilyushin from a short IL-76. This can be done to any IL-76 like it was done to the whole fleet of C-141As. There is now a conversion kit to upgrade the older IL-76 with more powerful, fuel efficient PS-90s engines. Indian aviation industry is quite capable to convert the IL-76 to full glass cockpit, with a full suite of modern avionics, including flight follwing radar and a modern DAS suite. The same air to air refuelling boom receptacle as installed in the the A-50 can be installed on IL-76s, just like was done to the C-141A when it was converted to C-141B standard.
I find it peculiar that the greatest and most powerful nation in world finds it advantageous to spend millions to upgrade its older hardware in order to get more use out of them, but that countries such as India, which have the industrial capability and technical expertise to do the same, are encouraged to ground and retire aircraft which still have ample potential, in order to buy new and expensive hardware, over which they will have no control once they are purchased (Although this may be true in the case of older fighters such as the Mig-21, helicopters, bombers and transport aircraft can easily be upgraded to get more life out of them. The USAF still has hundreds of 1950s and 1960s B-52s and KC-135s on inventory.
If India buys C-17s, it will also sign a long-term service contract with Boeing to maintain these aircraft and Indian Aviation industry will get nothing in return. If India decides to upgrade its entire fleet of IL-76 with modern engines, to stretch them, to install glass cockpit and a modern DAS as well as in flight refuelling, it will end up with a cheaper and very capable modern strategic aircraft with very good tactical capabilities and Indian aviation industry may get some work out of it. If the Il-76 was not upgraded over the years, it was not because the aircraft's technical capabilities or potential, but rather because of the economic situation of Russia and of most countries that operated the Il-76 in the nineties which could not afford to invest in upgrading their fleets. India is now one of the largest operators of the IL-76 in the world, and the owner of the most modern IL-76 in the world, the new A-50 AWACS. A contract to upgraded and modernize 30 IL-76s will receive instant attention by Ilyushin if India decides to go that route as they did with their An-32s.
The alternative is for India to retire its IL-76s and purchase C-17s and sign a 20 year maintenance contract with Boeing for the service of the C-17. Then India will have to toe the US line if it wants it C-17s to keep flying. Ask Pakistan, France, Iran, Venezuela and others about their experience with purchasing US aircraft.......it always comes with many strings.
