QUICK REFERENCE HANDBOOK (QRH)
DISCLAMER: This publication is to be used as a quick reference handbook and is to be read and used in
conjunction with the aeroplane flight manual and standard operating procedures. It does not replace or
supersede the aeroplane flight manual. It is the responsibility of the pilot in command to comply with all
relevant performance and documentation criteria relative to their flight operations. This QRH does not
include all abnormal or emergency procedures listed in the aeroplane flight manual.
QRH COLOUR INDEX Meaning
BLUE: - Memory Items/Flow Checks –Normal Procedures –
Actions to be completed without reference. (Have a grey
background)
YELLOW: - Do List –Normal Checklists –To be read line by line.
GREEN:- Aircraft Type Information.
RED:- Emergency Procedure –Actions to be completed from
memory and without reference. (Items with grey background
are memory items)
ORANGE: Abnormal procedure –Actions to be completed by
checklist as per the CAS message.
DEFINITIONS:
Land Immediately –The urgency of the landing is paramount. Emergency descent normally required with a
landing in an open field.
Land As Soon As Possible –Land without delay at the nearest suitable airfield at which a safe approach
and landing is assured.
Land As Soon As Practical –Landing at the discretion of the pilot. Extended flight beyond the nearest
approved landing area is not recommended.
Required Performance –In compliance with CASR Part 91.
OEI –One engine inoperative.
Decision Point –The point during the take-off phase, that the PIC makes the decision to either, abort the
take off and land straight ahead utilising any run off area, or continue the take-off, climb and emergency
procedure.

PRECAUTIONARY LANDING
NOTE
A landing of this type is only necessary when there is a reasonable suspicion that due to
operational factors such as fuel shortage, weather conditions, etc. the possibility of
endangering the airplane and its occupants by continuing the flight cannot be excluded. The
pilot is required to decide whether or not a controlled landing in a field represents a lower
risk than the attempt to reach the nearest airfield under all circumstances.
NOTE
If no level landing area is available, a landing on an upward slope should be sought.
1. Select appropriate landing area.
2. Consider wind
3. Approach:
If possible, the landing area should be overflown at a suitable height in order to recognize
obstacles. The degree of offset at each part of the circuit will allow the wind speed and
direction to be assessed.
4. ATC …………………………………………………….…………………………………………………………………… ADVISE
5. Touchdown …………………………………………………………… WITH THE LOWEST POSSIBLE AIRSPEED
CAUTION
If sufficient time is remaining, the risk of fire in the event of a collision with obstacles can be
reduced as follows after a safe touch-down:
- ENGINE MASTER ……………………………………. BOTH OFF
- FUEL SELECTOR …...………………………………… BOTH OFF
- ELECT. MASTER ….………………………………………..….. OFF
