Dash 1 Section 3 Flashcards
What are the three basic rules in any airborne emergency?
- Maintain aircraft control
- Analyze the situation and take proper action
- Land as soon as conditions permit.
What is a critical action?
An action which must be performed immediately if the emergency is not to be aggravated and injury or damage are to be avoided.
What is a non critical action?
Actions which contribute to an orderly sequence of events, improve chances for the emergency action to be successful and serve as clean-up items.
What is the definition of land as soon as possible?
1) . An emergency shall be declared
2) . A landing shall be accomplished at the nearest suitable landing area, considering the severity of the emergency, weather conditions, field facilities, ambient lighting, and command guidance.
What is the definition of land as soon as practical?
Emergency conditions are less urgent, the mission is to be terminated but an immediate landing may not be necessary.
What is the definition of a suitable landing area?
A hard surface runway, taxiway, or under/overrun.
The engine start should be aborted for what five situations?
1) . High ITT (hot start)
2) . Normal N1 increase is halted (hung start)
3) . No ITT rise within 10 s of fuel flow indications (no start)
4) . BAT BUS annunciator comes on
5) . ST READY light goes out/PCL moved
How do you abort a start?
1) . If PCL is OFF, set STARTER SWITCH to AUTO/REST
2) . If PCL between OFF and IDLE, set PCL to OFF or set STARTER SWITCH to AUTO/RESET
3) . If PCL above IDLE, set PCL to OFF
True/False. If a start was aborted while connected to external power, you may attempt subsequent restarts so long as no engine limits were exceeded.
False. There is an aircraft malfunction if it’s unable to start with external power.
When do you perform an emergency engine shutdown on the ground?
Prop strike, CHIP light, FIRE light, depart prepared surface and any other situation the pilot deems necessary.
What factors affect a pilot’s decision to takeoff or abort?
1) . Runway length and condition, weather, and area traffic
2) . If adequate directional confirm cannot be maintained or a system emergency is encountered prior to Max Abort speed
What systems run off hydraulic pressure?
NWS, main gear, main gear doors, speed brake and flaps
What indications will you have that the hydraulic pressure transmitter has failed?
Hydraulic pressure will read 0 psi but all hydraulic systems will operate normally
Loss of hydraulic pressure without illumination of EHYD PX LO or HYDR FL LO may indicate what?
An engine-driven hydraulic pump failure.
Low hydraulic pressure is considered what and will necessitate what?
1800 psi and will necessitate using emergency gear extension.
When should you consider divert with certain rudder malfunctions?
If unable to achieve full left or right rudder, crosswinds exceed 15 knots and fuel is a concern.
True/False. With a rudder trim push rod failure the cockpit trim position indications will respond and the rudder pedal forces will adjust accordingly.
False. The cockpit trim indications will respond to trim inputs but will have no effect on rudder pedal forces or actual trim tab position.
What may a fully deflected rudder trim gauge be indicative of?
Runaway rudder trim or an out of trim rudder condition.
What is a concern when testing rudder deflection during a rudder system malfunction?
Switching rudders too quickly which can result in an OCF if not neutralizing the rudder in between.
Keep airspeed between what range during a rudder system malfunction check?
125-140 KIAS
Climb how high before attempting rudder system malfunction checklist (if able)?
6,000’ AGL
If the aircraft slip indicator is fully deflected remain below what airspeed?
140 KIAS
True/False. If must divert and fuel is a consideration for the range, it is permissible to raise the gear and repressurize the aircraft in order to reach a suitable alternate.
True.
What check should be done after reaching a suitable alternate following a rudder system malfunction?
Controllability check.
During a controllability check to what minimum airspeed can the aircraft be slowed?
90 KIAS or activation of stick shaker, whichever is higher
If unable to manipulate a control surface what should you consider (DUAL ONLY)?
Control may be available from the other cockpit.
How do you determine if the rudder will be available for landing following a bird strike or structural damage to the aircraft?
Attempt all power options, especially IDLE which will simulate the flare in landing.
Fly no slower than what after a controllability check situation?
Minimum controllable airspeed plus 20 KIAS.
What kind of approach should you execute following a controllability check situation?
Power-on, straight-in approach with minimum flare. Touchdown at no less than previously determined minimum controllable airspeed
Without full rudder authority and with a crosswind component greater than 5 knots how should you land?
Fly a no-flap, straight-in and use differential braking on landing roll to stay on prepared surface.
Landings have been accomplished at what airspeeds with landing flaps and flaps up?
110 KIAS and 130 KIAS respectively.
Illumination of the OBOGS FAIL annunciator indicates what?
Loss of sufficient oxygen concentration or pressure.
OBOGS may have failed because of what?
Failure of OBOGS heat exchanger, concentrator, bleed air supply, electrical system interface, excessive system leakage
What should you do if you have an OBOGS FAIL at low PCL settings?
Advance the PCL to extinguish the OBOGS FAIL and continue as normal if it extinguishes.
When is it possible to experience hypoxia symptoms?
If OBOGS has malfunctioned and cabin altitude is above 10,000’ MSL.
How long will emergency oxygen last?
10 minutes.
If at a certain altitude what descent rate is needed to achieve 10,000’ within 10 minutes?
31,000’ MSL, 2100 fpm
28,000’ MSL, 1800 fpm
25,000’ MSL, 1500 fpm
23,500’ MSL and lower, 1350 fpm
What if you have respiratory irritation, coughing, or white dust in the oxygen mask?
This could also be an OBOGS system malfunction caused by an issue with the concentrator beds which releases zeolite into the mask.
How should you breathe when under emergency pressure?
At a rate and depth slightly less than normal.
The OBOGS TEMP light indicates what?
Failure of the OBOGS heat exchanger.
The DUCT TEMP annunciator indicates what?
Bleed air temperature in the environmental systems duct has exceeded 300 deg F.
What will occur at altitude with the BLEED AIR INFLOW switch set to OFF?
Cabin pressurization will bleed out and the pressure seal and anti G systems will not be available.
What can you use if the Defog valve fails to close in flight and cockpit heat is uncomfortable?
The TEMP CONTROL switch.
What airspeed will best reduce control forces when have runaway trim?
110-150 KIAS
