Emergency Flashcards
emergency situations
RT procedures and phraseology is the only way to summon outside help
needs to be transmitted
- Quickly
- ## Correctly
Factors to keep in mind..
Distress has highest priority
**Urgency has 2nd highest priority
**
Use slow and clear and proper phraseology
**avoid repetition **uncessarily
Set trasnponder code to 7700 BEFORE you transmit the emergency message.
distress/urgency calls should be made on the frequency currently being used and continue to use it..
if the existing frequency isn’t supportive, use 121.5 MHz
all other pilots hearing the emergency transmission on the same frequency, should not make any further trasnmissions unless involved in the emergency assistance
if pilots intercept an emergency message that isn’t receving any assistance, they should ACKNOWLEDGE the message and RE-BROADCAST it to the ground station being addressed
Distress/urgency message components

name of station/service
aircraft call sign
Type of aircraft
Nature of distress condition
Intention of the person in command
current position
current FL or altitude

Engine on fire, Making forced landing 10 miles South of Steerton,
Passing 3000ft, heading 360, PPL, 2 POB.
GS:
G-FHJM, Steerton Tower, Roger MAYDAY, Surface wind at
Steerton 230°, 10 knots, Steerton QNH 998.
Imposition of silence (stop transmitting)
A GS in control of a distress situation may ask other aircraft on that same frequency to stay silent
AG:
All stations, Steerton Tower, Stop transmitting, MAYDAY in
progress.
Cancel distress message
(cancel distress)
Pilot needs to initiate it.
AC
Steerton Tower, G-CD, Cancel distress, Engine re-started, Field in
sight, Request landing.
GS
G-CD, Runway 20, Wind 210 degrees, 10 knots, Cleared to land.
AC
Runway 20, Cleared to land, G-CD.
ground station will cancel the distress transmission and cancel the silence condition
aircraft relaying a message from a distressed aircraft to GS
(Intercepted emergency call from ‘Call sign’)

Ending a distress transmission
pilot must ‘tell’ the controller before existing the emergency 121.5 frequency
