High end mechanical pilots watches are very little use in the cockpit whether you are in a commercial airplane or a cessna 152. I love watches and I've searched for years for a watch that was a) very cool looking and b) actually useful when flying and I haven't found one yet. They usually fail on b) because their analogue chronometer and/or timer functions ...

If a door is put into armed mode, it will trigger the evacuation slide when the door is opened. Prior to departure (usually before engine startup), all the aircraft doors are placed into the armed (or automatic) mode by the cabin crew. Methods of arming vary from aircraft to aircraft, but ultimately the girt bar (a metal bar attached to the door end of the ...

These are part of the foot restraint system fitted to the seats used in the SR-71, later U-2 and some Space Shuttles. (They're all derived from the same basic design). The spurs engage in two ball nipples that protrude from the lower part of the seat. The nipples are connected via cables to reels beneath the rear of the seat which pull the pilots feet in ...

That is the mounting point for night vision goggles. The following image shows a helmet with NVG mounted. Helmet mounted NVG; image from lemt.by The USAF has helmets with different mounting and some of the modern pilot helmets (like BAE Striker II, for example) have an integrated night vision device.

Disclosure: I am both a watch enthusiast and a Pilot but on any note... The answer to your question is generally no, but that varies by personal taste as well as personal choice. There are lots of threads on the various watch forums discussing this very topic here, here and here. The consensus is basically a few things. First off pilots no longer make the ...

Watches in today's cockpits really aren't a tool the way they were in the past. We aren't using our wristwatch as a chronograph to manage dead reckoning the way that was required before such modern luxuries as Loran gasp. Wristwatches are more about expressing your style. It is more about jewelry. With the exception of a 24 hour Zulu hand, and a 24 hour ...

(airliners.net) Ejector on the Rolls-Royce Conway of a DC-8. It's called an ejector. Introduced in c. 1958 by Douglas for their DC-8, it is extended during takeoff and landing, and stowed during the flight because it increases the drag at high-speed flight. In the extended position it acts as a noise suppressor, and it also reclaims thrust that has been lost ...

(Source) Ju 88 model. Not just the 87, some Ju 88 models also had it, with no access to it in-flight. As mentioned, it's an antenna. The antenna is part of the EZ6 direction-finding unit. The glass is not for viewing. It's the construction method to keep the installation as thin as possible. The sense antenna is painted on the glass. The PRE/6 ferrite ...

Short answer Corsair is a small airline, with a limited number of aircraft, serving airports in remote islands from Paris. For their economical survival their aircraft must keep a high operational ratio. However: The airline may not have a maintenance facility at destination, either a owned facility or an agreement for maintenance services from another ...

This is an issue on airline passenger safety that has been debated since a very long time, and there are various arguments for and against the use of smoke hoods. A classic example which showed the requirement for smoke hoods was the British Airtours Flight 28M, which had an engine failure during its take off roll at Manchester International Airport in ...

Short answer It seems to be a US Army CEASAR pod, a communication intercepting and jamming system for electronic warfare, which has been flown in Iraq and Afghanistan. CEASAR is derived from AN/ALQ-227 EA used by US Navy on the EA-18G Growler. The aircraft is equipped with missile detection and countermeasures. Two sensors are below the cockpit windscreen, ...

I have worked on and designed DIRCM systems. Most of the technical specifications on these systems is classified. Also, the U.S. is not the only country with DIRCM systems. In particular, Israel is equipping their airliners with the C-MUSIC system. How does this system work? Basically, a laser at the wavelengths of the Infrared Missile seeker is directed ...

There are four different types of ELTs: Automatic fixed ELT (ELT(AF)). An automatically activated ELT which is permanently attached to an aircraft. Automatic portable ELT (ELT(AP)). An automatically activated ELT which is rigidly attached to an aircraft but readily removable from the aircraft. Automatic deployable ELT (ELT(AD)). An ELT which is rigidly ...

(Source) Externally, the Connie (shown above) had lights, with the red being the now obsolete passing light. From the high-res DC-3 and DC-7 cutaways, all sort of stuff, from autopilot oil and air filters, wiring, windshield spray systems, to hydraulic reservoirs. There wasn't one main object like there's now, nor was it completely empty. Its main ...

They are filled with carbon dioxide, oxygen and nitrogen. See here for reference. From the linked article: Slides inflate with an initial boost from a canister of compressed carbon dioxide and nitrogen. The canister provides only about one-third the volume needed to inflate the slides. The remaining volume is supplied by ambient air, channeled into ...

When the door is armed, the slide will deploy when the door is opened. The tape is indeed an indicator to people outside that the door is armed.

According to the NTSB, the accident airplane did have a functioning autopilot and GPS. The airplane was equipped with a Bendix/King 150 Series Automatic Flight Control System (AFCS), which was approved for use in Piper PA-32R-301 model airplanes by the FAA on November 1, 1982. The AFCS provided two-axis control for pitch and roll. It also had an electric ...

Some modern audio panels allow for independent volume control for pilot (left seat), co-pilot (right seat) and passengers. For example, a popular panel, the Garmin 340 has controls on each side of the panel, left for Pilot, right for Co-pilot: Another popular panel, the PS Engineering PMA-series only separates out the Crew from the Passengers. In that case,...

Cannulas are not effective above medium altitudes, and the FAA prohibits their use above 18,000 feet (FAA brochure on Oxygen Equipment, PDF). Because they only place oxygen at your nose, you don't receive oxygen when talking or breathing through your mouth, while a mask covers both nose & mouth. This is, obviously, not great. Cannulas are also less ...

How does this system work? Guardian is basically a Directional Infrared Counter Measures (DIRCM). By using an infrared laser (and an optical parametric oscillator to generate a second IR Band wavelength) the Guardian jams the IR seekers of incoming Infrared missiles through their sensor apertures. Does this successfully work in countering all types of ...

@mins got this one right. It's a British Tigercat short range surface to air missiles launcher system. The cones are protective weather covers for the missiles which are removed prior to launch. As to the 'buckets and chains' I'd venture a guess that they are a device to deflect and dissipate the rocket blast during launch but I am not totally sure. But ...

First we should see how active noise reduction works. The simplest definition would be: Active Noise Cancelling uses electric signals to reduce unwanted sounds. The following picture on Active noise control depicts it in a simple manner: Then we can see what unwanted sounds ANR can actually reduce. As mentioned in A Guide To Buying An Aviation Headset: ...

In Britain it's a Tiger Cat and in the South African defense force it was called a Hilda missile system. I operated one when I did national service there. The missiles are connected to a firing console via a thick cable. In the console you have a missile controller and computer operator. The missile controller controls the missile with a little teet (joy ...

I think it's a transparent cover for a direction-finding loop antenna. The rear gunner doubled as navigator, and probably needed to check the position of the moveable loop antenna. Ref.: Luftfahrt Bilder, Texte, Dokumenten Mittler Verlag 1978 Page 3389

While probably legal to fly over the Atlantic VFR, it appears getting out of Canadas airspace is a different matter. After a bit of googling I found this article on COPA's website, saying: Both for flying in the northern parts of Canada as well as in Greenland airspace, an ADF is legally required (refer to TC AIM 3.16.10 and CAR 605.18). I didn’t have ...
