| #17 So how did they fix the exhaust problem? Early on, it was reported that the exhaust was so hot it would melt the flight deck. Posted by Juting Clolugum7534 As far as can be told, they didn't. With the typical brilliant bureaucrat logic, it apparently was decided to fix the problem by reinforcing the flight deck, use heat resistant concrete in runways, et. al.. |

| #16 Military O2 Requirements: AIR FORCE INSTRUCTION 11-202, VOLUME 3 6.4. Oxygen Requirements. (N/A for UAS ground control stations) The PIC shall ensure sufficient oxygen for the planned mission (including contingencies) is available to all occupants before takeoff. Normally, aircrew will use supplemental oxygen anytime the cabin altitude exceeds 10,000 ft MSL. 6.4.1. Unpressurized Operations. When mission essential, aircrew trained IAW AFI 11- 403, Aerospace Physiological Training Program, may operate aircraft unpressurized above 10,000 ft. MSL without supplemental oxygen IAW MAJCOM guidance and the following restrictions: 6.4.1. (ACC) Unpressurized Operations. For any scheduled mission where cockpit pressure will exceed 18,000 feet MSL, all aircrew members/occupants will prebreathe 100% oxygen for at least 30 minutes prior to the cabin altitude exceeding 10,000 feet MSL. Any break in this prebreathing cycle will require either starting the cycle again or removal of the affected individual from the flight. 6.4.1.1. Total flight time (without supplemental oxygen) above 10,000 ft. MSL shall not exceed 1 hour if any portion of the flight above 10,000 ft. MSL is in IMC, at night, or when using NVGs, employing weapons, conducting airdrop or air-refueling, or performing high-g maneuvers. 6.4.1.2. Maximum of 30 minutes (without supplemental oxygen) between 12,500 and 14,000 ft. MSL. 6.4.1.3. Supplemental oxygen must be used by all persons while above 14,000 ft. MSL. 6.4.1.4. Any occupant, not trained IAW AFI 11-403, limits the cabin altitude to: 6.4.1.4.1. 10,000 ft. to 13,000 ft. MSL for three hours without supplemental oxygen. 6.4.1.4.2. 13,000 ft. MSL without supplemental oxygen. 6.4.1.5. FL 250 shall not be exceeded even if occupants have oxygen (see paragraph 6.5) 6.4.2. Pressurized Operations. Pilots flying pressurized aircraft maintaining a cabin altitude below 10,000 ft. will comply with Table 6.2. Each crewmember shall use supplemental oxygen anytime the cabin altitude exceeds 10,000 ft MSL. 6.4.2.1. (Added-ACC) The following oxygen restrictions apply to aircrew members: 6.4.2.1.1. (Added-ACC) Bomber crewmembers will wear oxygen masks from initial takeoff to the initial oxygen check. Additionally, bomber pilots will wear oxygen masks during air refueling from pre-contact through termination of actual refueling operations and from the final approach fix or turn to visual final through landing or missed approach. 6.4.2.1.2. (Added-ACC) In the B-1, when readily available oxygen is required, the helmet with oxygen mask attached satisfies this requirement, provided adequate oxygen sources are available. 70 AFI11-202V3_ACCSUP_I 28 NOVEMBER 2012 6.4.2.1.3. (Added-ACC) When readily available oxygen is required, the troop oxygen system with troop masks installed, satisfies this requirement for aircraft so equipped. |

| #15 the wings don't appear to fold I wonder how many they can store? The F-35C (intended for USN and MC carrier operations) has foldable wing tips. Al |

| #13 #11 I thought all domestic units were grounded last week due to pilot air? Posted by Skidmark The air show planes are not flying high enough to require supplemental oxygen use. I think they can fly up to 12,000 feet before the pilot is required to use supplemental oxygen. TW, thanks, I'll remember that from now on, luckily it doesn't happen too often. |

| #12 It appears I'm only allowed a maximum of two links per comment post. Right. Fred instituted that rule, Seeking cure, when we were having a spam problem in the Burg. Made my life a bit difficult until I internalized it; but as you just discovered, it's survivable. ;-) |

| #9 (Continued from previous post) F-35B F-35C There are also other versions, I will post link to those in another comment. |

| #8 #1 Huh, must be 2. I thought that one was at the airshow. Posted by Skidmark Skidmark, there are three variants of the F-35. The one at the airshow is the "A" variant, while the navy one above is the "B" variant: F-35A (continued in next post) |

| #7 Skid there are around 200 of them ATM. |

| #5 Mods, what happened to my reply? |

| #4 The Marines will probably like it then. I didn't see if it had a lug for the bayonet. |

| #3 The Harrier's wings also don't fold. |

| #2 I guess rough weather landings will be the next tests? Since the wings don't appear to fold I wonder how many they can store? |
