The risk of midair collision is greatest from takeoff to top of climb, and again from start of descent to landing. Don't assume you'll always be able to 'see and avoid.' You, the pilot, are responsible for your own separation and lookout. These tips will help.

Lookout: — Stay focused on looking outside.

Don't let routine tasks (programming GPS, paperwork, etc.) or familiarity with an aerodrome cause you to relax your lookout. Consider adopting 'sterile cockpit' procedures while climbing or descending. Cockpit activities should focus on lookout.

Complete most checks and briefings prior to descent so you can concentrate on procedures and lookout. 

Listenout: — Let your ears be your eyes.

Always monitor the recommended or mandatory frequency.

Get on frequency well before entering the ATF/MF zone to establish traffic awareness.

Monitor the ATF or MF throughout climb and descent.

Speakout: — By verbal, visual and electronic means.

Keep others aware of your position.

Transmit initial advisories and updates on the recommended or mandatory frequency giving your position, altitude, intentions and ETA.

Be conspicuous. Select position/strobes/landing lights "ON". Transponders provide Air Traffic Services and TCAS equipped aircraft with traffic avoidance information. Turn them "ON".

You can make flying safer — remember to:
