![]() Think big asphalt parking lot in Houston with Jet exhaust everywhere. On the deck of the carrier we were required to have our canopy open, and without much power on the aircraft, there was almost no cooling. Don't remember it ever getting too bad though, because we could have the canopy closed. While on the tarmac was one such time, and this due to limited power on the aircraft, and hence lower pressure bleed air. There were times where the system was not quite useful. The oxygen was conditioned and so was always cool on the face, and not uncomfortable. Full gear was: wet suit (cold water operations), flight suit, g-suit, LPA and survival harness, helmet with visor down, flight boots, Nomex gloves, and oxygen mask on. This was true for the coldest to the hottest days I experienced. While airborne, with an operable air-conditioning unit, the cockpit was very comfortable. The anti-g suit also uses air provided by the air conditioning unit. In my squadron very few of the pilots used anti-exposure suites, and most used wet suits when flying over cold water (less than 60 degrees F). The air-conditioning system also provides anti-exposure suit ventilation and this is controlled separately from cockpit temperature. See the image below for the pictures and locations of the controls. There is cockpit over-temperature protection which is provided in automatic and manual settings, and limits the cockpit temperature to 210 degrees F. The A7-E cockpit temperature is maintained either manually or by setting the cockpit temperature with the temperature control knob. After here it enters compressor wheel section of the a/c unit, where the heat exchanger reduces the temperature of the bleed air. In the A7-E the air-conditioning system takes high pressure bleed air and passes it through the primary heat exchanger. Quick Introduction to the Airconditioning Unit The following image shows the other controls associated with ECS. When L ENG or R ENG, bleed air is supplied from the left/right engine only. When BOTH, bleed air is supplied from both engines. MIN, MAX and NORM settings are available for minimum/maximum/normal air flow, respectively.įLOW knob: A four-position knob to set the air source. TEMP knob: A rotary knob to set the cockpit temperature.įLOW switch: A three-way switch to select air flow. When MANUAL, cockpit temperature may be changed with the knob, but not maitained automatically. When AUTO, cockpit temperature is automatically maintained at the temperature selected on the TEMP knob. ![]() TEMP switch: A three-way switch to manage cockpit temperature. For example, in case of F-15, the following system is available: The cockpit air conditioning is usually managed by the pilot. The systems usually use conditioned engine bleed air or this purpose. Their primary functions (as far as cockpit goes) include, In general, they are called as Environmental Conditioning Systems (ECS). Fighter aircraft have air conditioning systems.
