Immediate Actions

G500 Emergency Procedures

There has long been an industry-wide trend to deemphasize so-called "memory items," "bold print," or what is probably best summed up as "immediate action" items. I write about that in great detail here: Immediate Actions. While Gulfstream's official position is to not identify "memory items," there are things you are expected to know how to do immediately, without reference to a checklist. Here they are.


[AFM, §00-20-20]

  1. The following is applicable should any abnormal event occur:

    1. Maintain control of the airplane.

    2. Other than retracting the landing gear and silencing aural warnings, take no action until altitude greater than 400 feet AAL.

    3. If a CAS message contains a directive consequential alert, the action associated with the consequential alert should be accomplished without delay.

  2. Gulfstream’s philosophy is to not identify any steps in abnormal or emergency procedures as so-called “memory items”. Pilots are expected to perform some initial and critical steps without reference to any documentation. The following are examples of procedures that the initial/critical steps should be performed promptly without reference to a checklist:

  3. In addition, crews are expected to don oxygen masks and smoke goggles promptly when appropriate – for example when smoke is detected. Operators and training providers must ensure that pilots are trained in accordance with this or other acceptable defined procedures that satisfy these provisions for time-critical emergencies.

  4. During certain flight control emergencies a shallow approach is recommended for landing. The shallow approach segment should be commenced once the landing runway is in view and target a descent angle of approximately 2.5°, terrain and obstacles permitting.

Engine failure above V1

Immediate Action Items

  • Continue takeoff

  • Max Takeoff Thrust

  • rotate, gear up, V2 to V2+10

  • at 1,500 feet, VSE

  • after V2+20, flaps up, affected engine idle and fuel control off, checklist.

Engine Failure Above V1

Cabin pressure low/emergency descent

Immediate Action Items

  • Don oxygen masks, establish cockpit communications, deploy passenger masks, idle, set FPA -8°, VMO/MMO, extend speed brake smoothly to avoid AOA limiting, 7700, ATC, level off at 10,000 feet or minimum en route altitude if higher, checklist.

Engine exceedance

Immediate Action Items

  • Ground: idle and off.

  • Flight: confirm engine, reduce power, checklist.

Engine Exceedance

Enhanced ground proximity warning system (EGPWS)/windshear/Traffic Alert and Collision Avoidance System (TCAS) alerts

Immediate Action Items

  • For a predictive windshear: avoid it. (Don't takeoff or go around.)

  • For a windshear or EGPWS "Pull Up" alert: disconnect autopilot and autothrottles, pitch up smoothly up to full aft stick (30° maximum), power levers full forward, once safe climbout assured, retract gear and flaps.

  • The TCAS alert procedure isn't clearly spelled out yet but you are basically flying the FPV into a green box on the PFD until clear of the traffic, and then returning to altitude while telling ATC "TCAS RA" and "Clear of conflict, returning to assigned altitude." [AC 120-55C, App. 5, ¶3.]

Windshear

Sidestick fail

Immediate Action Items

  • Identify who is flying, keep pitch trim in trimmed condition.

  • If either sidestick is passive, turn the autopilot off, press and release the FLT CTRL RESET. Refer to checklist.

Sidestick Active/Passive Unlinked

Sidestick Both Passive (Unlinked)

Sidestick Link Failure

Ground spoilers armed

Immediate Action Items

  • Do not retard throttles to idle, if gear still down slowly apply parking brake to stop wheel spin, release, refer to checklist.

Brake-by-Wire fail (U) (ground procedures)

Immediate Action Items

  • Use the parking brake to stop.
