I'll assume two different aircraft are being spoken about? The Norwegian F-16 with drag/brake chute and the Canadian ???????? with drag/brake chute? I'll guess the Canucks have experience with Voodoo and Starfighter drag chutes. How different are these to the F-16 chute in use today?

Norway also had chute's on their CF-104's as well, where the C means they were Canadian models

However the article states 'Norwegian F-16 pilots' so I'll assume they were not talking about F-104s.

I agreee, but it demonstrates that it was not only the F-16 that benefited from the chute. These two pilots are probably too young to have flown both fighters though. CF-104 pilots are either Generals, retired or flying B737 in SAS.

Not true – the drag chute for the F-35 will have a design to conform with the body of the aircraft and will have very little effect on its radar signature.

You know, I hadn't thought of it that way, but that would explain why the drag chute needs development beyond the spin chute.

Perhaps the F-35A drag/brake chute container will get some excess heat piped to it to stop the 'ice block effect'?

Like they said...

-At altitude, where the temperatures are minus 50 C, they tend to freeze and turn into ice cubes.

Not true – Norway has operated the F-16 with drag chutes in the high north for 30 years and we have not had any such issues with it

So the old Canadian F-104/Voodoo pilots were telling lies?

Lies? No, anicent memory is just as clear as present day operational experience Salute

How about this. Different aircraft - different brake/drag chutes - different characteristics. No memory loss and why we even discuss this seems a bit silly. We will see what we will see when the Norwegian Drag Chute mod is on the F-35A and tested. Then we will know worthwhileness or not. Personally I don't believe the original blog poster has a clue what was under discussion but it would be helpful to know more about Canadian pilots and to what they referred. But then again I personally don't give a damn. FLY NAVY! Very Happy

By the nature of where the chute appears to be located on the F-35 this would not be an issue. Look at the external pod it is in on the F-16 and then its location within the main body, close to the engine, on the F-35

Had a chat with a RNoAF old timer. There were apparently no issues with the chute on the F-104 or even the F-86. The Russians have used it for decades too. As for icing you dry off the chute before using it, so there wont be any problems.

Good point about drying the chutes. In fact we had a tower looking building just for the purpose of drying drag chutes. Probably still there.

More info perhaps useful about 'landing and stopping' the F-35A in winter conditions?

Q3.16 Does the F-35A Conventional Takeoff and Landing (CTOL) variant need more runway to land than other comparable fighter aircraft?
A3.16 No. Upon landing the F-35 uses an efficient braking system, which includes computer directed flight controls and an advanced anti-skid wheel brake system. The aircraft is capable of unaided stopping distances equivalent to those of Canada’s current CF-18.

Q3.17 Does the F-35A have an arresting hook like the CF-18?
A3.17 Although the F-35A has an arresting hook, it is not designed for routine use. The CF-18 was originally designed for use on an aircraft carrier with regular use of the arresting hook.

As such, the more robust arresting hook on the CF-18 requires less maintenance and fatigue monitoring between uses than that of the F-35. This being said, the stopping capability of the F-35 arresting hook is equivalent to the arresting hook on the CF-18. The difference between the two arresting hooks is the maintenance action required after usage to prepare each arresting hook for the subsequent flight.

Q3.18 Can the F-35A stop on slippery and short runways like those often experienced at Canada’s northern aerodromes?
A3.18 The F-35 landing performance studies indicate that the aircraft can be stopped on a snowy runway in less than 6000 feet without the use of additional stopping aids. When runways are contaminated with ice or a mix of slush, snow, and ice, the F-35 will require an additional stopping aid such as a drag chute or the emergency arresting hook to stop in less than 6000 feet. This is similar to the CF-18, which regularly uses the arresting hook to stop on short runways in icy conditions...."

Maybe Canada should go for a F-35C then? Longer range and improved undercarriage and arresting hook.

Does anyone know the F-35C runway length requirements? Assuming non-arrested landing that is...

Norway may no longer require drag chute
