Air Brake set to "on" at cold start - Normal Procedure?

[Thisdale]

As title,

 

In a cold start environment, the Tiger's Air brakes are deployed.

Is that normal procedure?

 

It seems to be the only plane that does it this way?

 

 

(also, i keep forgetting to close them before takeoff... awkward).

The landing gear doors are also open (after landing, and turning off the engines, these doors "fall" into the open position as well); I assume that's all because of the lack of hydraulic pressure when doing a cold start...?

The saber is like this too. It's to do with no hydraulic pressure when the engine is off I believe

Bloody hell. That means i have to add this to my Start Procedure... i constantly forget about it.

 

Thanks for the reply guys.

Nope, it's not because of hydraulic pressure, but because of standard procedure - open airbrakes by pilot and gear doors by ground crew with switch in main gear well. It is used to ground examination of the interior of compartments, I believe

Yes and no,,,,,, allow me, the speed brakes as well as the gear doors are open during taxing.

If the aircraft arrives at the chocks and they are NOT opened and the aircraft is shut down before it is noticed (it happened, not that often but it happened), ground crews would have two choices to open the speed brakes and gear doors:

 

1) Hook up the air cart and motor the engines so they could be opened up this would require a engine run certified ground crew member to do this since not all ground crews were certified for this.

2) Hook up a hydraulic test stand and a power cart, pressurize the systems and energize the aircraft, then open the speed brakes/doors.

 

The "unofficial" was to open the gear doors was to pull the alternate gear release handle of the left side of the front cockpit or if your arms and hands were small pry open the gear door locks with a screwdriver.

It has been 20+ years since I worked on them so some procedures might have changed.

Was there any disadvantage to releasing with the alternate gear handle? (More maintenance etc.). That seems much easier than all the other ways once the engine was off.

When the alternate release handle was pulled in flight, it basically released the gear to free-fall so gravity would lock the gear down. The only disadvantage we could ever figure out was that if the reset switch was not placed in the reset position (up if memory serves me right) when the engine was started, there would be no way the pilot could release the gear if it was needed, the switch was down near the pilots left foot. We were required to either start the engine or hookup hydraulic and electrical power once the handle was pulled to reset the switch, can neither confirm or deny that step was followed.

Again, I could be getting my F-5 and T-38 systems mixed up!
