The names Bond, James Bond. In **Moonraker ** with Roger Moore (1979) 007 jumps out of a plane without a parachute to avoid an assassination attempt. He catches up with, Jaws, arch-baddie, in mid-air and takes his parachute. Jaws survives his fall by landing on a big top circus tent.

In **Point Break** with FBI agent Johnny Utah, Keanu Reeves, leaps from a skydiving plane after Patrick Swayzes’ characer, Bohdi, who has taken the last parachute. Utah catches Bohdi in mid-air, and after a tense confrontation with a gun, both survive using Bodhi’s chute. The remake was in 2015.

There are more movie and real life stories at the **Free Fall Maths** link.

Note: We’ll assume Bhodi and Utah have equal horizontal velocities (plane exit velocity plus wind) so the following calculations only involve the vertical or falling velocity. The terminal velocities used for Bhodi and Utah are realistic estimates.

So mathpigs, here is a small taste of what you would need to do to land a small aircraft in an emergency if the pilot is unconscious/dead.

# A = Airspeed

Find airspeed indicator on instrument panel.

Instrument Panel Piper PA-28

Check speed.

Knots or mph or kph?

Avoid red zone. Too fast.

Knots outer scale. mph inner scale. Recommended velocity between blue & red.

# B = Contact nearest air traffic controllers.

1. Call MayDay MayDay MayDay

2. Look for plane ID. It will be on instrument panel somewhere.

3. Check fuel.

On the Piper Cherokee there are 2 fuel tanks, R & L. Check both.

Check aircraft operating handbook to see fuel consumption and remaining time in air.

Quick calc.

# C = Checklist

Follow Emergency Landing Checklist in aircraft operating handbook for** Power OFF or Power ON landing****.**

Keep in mind, if your air speed is too low you can drop from air, but the higher the landing speed the bigger crash.

Crash energy increases with the square of speed. It’s a parabola!!!!!

The likelihood of a passenger with

## NO flying experience landing a plane safely in an emergency is

## very small.

The likelihood of a passenger with

## NO MATHS skills landing a plane safely in an emergency is

## ZERO.

# QWERTY Math uses KEYBOARD SHORTCUTS

# There are 10 math questions

## (pdf version and pdf ans below).

**The boxed sections are keyboard math symbol shortcuts.**

**When the students push these keys the Qs finally make sense. **

**eg. option v = square root sign**

**BUT:**

### 1. They must have a computer with a KEYBOARD (not a tablet)

### 2. The computer must be a MAC*

### *Mathspig tried to find the QWERTY Math shortcuts on her old PC and it went crazy!!!!

**Albert Digital Mathematical clocks are fascinating. **

**You calculate the time using +, -, x and ÷ . Such fun and ideal for the math classroom.**

**Mathspig found the Albert Mathematical clock at the Horsham International Hotel (below). **

**More info on the Albert Digital Clock here.**

**You can set the level of difficulty. You get 1 minute to work out the answer and that’s long enough.**
