SHORTFIELD CIRCUITS
Aim: To operate safely and efficiently into and out of a field of marginal length, using as little runway as possible. Application: - short/rough strips - ALA’s - obstacle clearance Revision: P-Charts FACTOR Increase Weight Increase Headwind Increase Temperature Flap Upslope TODR LDR
↑ ↓ ↑ ↓ ↑
↑ ↓ ↑ ↓ ↑
Definitions: Short Field - When the runway length available and/or obstacle clearance gradients are only just sufficient to satisfy take-off and landing requirements. Principles: TAKE OFF Flap
- Reduces Vs therefore reducing VTOSS (1.2Vs) - Shorter take off run and distance to 50 ft AGL - Provides better obstacle clearance Power Vs Brakes - Ensures maximum power available to achieve maximum acceleration - Exercise caution on gravel surfaces Climb Performance - Rate and Angle of climb will both decrease
APPROACH AND LANDING Flap - Reduces Vs allowing approach at minimum speed (1.3Vs) Power - Allows slower flight on the back of the drag curve - Inboard surfaces (rudder/elevator) more effective Approach Profile -Same flight path flown with a higher nose attitude due less airspeed Landing- Shorter positive flare and touchdown - Use maximum braking as required
