How does the hydraulic system work

6 hydraulic pumps provide pressure to 3 independent hydraulic systems . each system is pressurized by 2 pumps. Systems 1 and 2 are pressurized by their respective engine driven pumps and electrical backup pump. System 3 is pressurized by 2 hydralulic pumps

When should flaps 8 be added

After approach and in range checklists, at 180 kts

What is coffin corner

Coffin corner is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep an airplane in stable flight.

when can u descend in a PT ?

abeam the fix inbound

air wis robert binns

glideslope descent rate rule of thumb:

airspeed x5

What is Mach tuck

anywhere from 0.75 Mach to 1.2 Mach. When the first molecule reaches speed of sound, shockwaves form. Aerodynamic center moves aft, As air flows from the supersonic region in front of the shockwave, to the subsonic region behind the shockwave, it separates and becomes turbulent.

three factors that affect VMC:

density altitude, Gear, "keel" affect. CG

Flaps are

electrically operated

what is an emas?

enigineered materials arrestor system

what side around an anvil>?

upwind, away from anvil side

Dutch roll:

yawing towards raised wing due to more lift and drag

When should flaps 20 be added

170 kts, prior to intercepting final approach course

At what altitude does class b speed restriction end?

10,000

what bleed air is used for pressurization?

Holding airspeeds:

How many gens doe scrj have

1 APU gen, 2 engine driven, 1 ADG

What is a hung start

A hung start occurs when the engine lights off normally but doesn't accelerate to idle RPM. This is usually the result of insufficient power to the engine from the starter.

What is a hot start

If the engine experiences unusual difficulty accelerating during start, a hot start may occur. There won't be enough airflow to cool the initial combustion of fuel within the engine. Acceptable temperature and time limits are published within individual aircraft flight manuals to prevent engine damage.

How to recover from Mach tuck

Recovery can be attempted by lowering the gear, extending the dive brakes, and lowering the flaps. Drag needs to be increased. Recovery is sometimes impossible

What is mcrit

When Mach number equals 1 (speed of sound).. aircraft will begin Mach buffet

What is Y and Z on an appraoch ??
